Description
The cross reference of related application
The application requires to be filed in the U.S. Provisional Application No.61/138 on December 16th, 2008,044 priority.
Technical field
The application relates to from the container that is arranged in surperficial facility and carries the material of scale preventative chemicals for example so that hydrocarbon well is carried out scale preventative squeeze treatment under water under water to submarine site and subsea well.
Background technology
Used equipment can produce incrustation and inorganic matter crystalline deposit in the hydrocarbon production operation.For example, under a kind of typical situation, because oil-bearing stratum flooding, for example be injected in the oil well and can produce fouling when formation water in the oil well mixes at seawater.Fouling also can be in stratum or recovered water the solubility hypersaturated state of mineral produce when changing because of pressure and/or temperature change.Fouling also can be because of nucleating point, for example sand and corrosion and increase.The fouling sediment can comprise various mineral, for example calcium carbonate, calcium sulfate, barium sulfate, magnesium carbonate, magnesium sulfate and strontium sulfate.For example, when utilizing seawater to inject the hydro carbons of exploiting storage, be easy to take place the sulfate scale deposition.
This fouling can occur in inside and outside the oil well, for example makes in the oil pipe or miscellaneous equipment that the production fluid from oil well flows through, and is important mobile assurance problem in oil and gas industry.In some cases, the fouling meeting reduces or hinders the flow that flows through hole and oil pipe, hinders the proper operation of valve and pump, and otherwise interferes the operation with the oil well relevant device.
There are several methods that can be used for controlling incrustation.For example, the fluid method of modifying comprise water (for example, aquifer water or desulfurization water) with different component be injected in the reservoir and make water and the extraction flow point from.The most popular method that prevents and handle incrustation is to apply the chemicals that plays the scale preventative effect.This chemical inhibitor or scale preventative can be water base, oil base, suspended emulsion, micro encapsulation seal, porous dipping spherolite and multifunctional product (for example, anticorrisive agent/scale preventative, pitch inhibitor/scale preventative etc.).Scale preventative adopts the operating principle that stops nucleation and crystal growth usually.Many scale preventatives can be applied to extraction liquid stream or be injected into well by the scale preventative squeeze treatment by continuous injection.The typical scale preventative squeeze treatment that utilizes scale preventative that well is handled comprises flowing of the production fluid that interrupts artesian well, scale preventative is injected in the reservoir by well, makes that the rock matrix in scale preventative and the reservoir reacts to be absorbed in the stratum and to be deposited on the mineral surfaces subsequently.Typically, squeeze treatment comprises injects pre-rinse solution, injects chemical inhibitor (main flushing) thereafter, injects afterflush (overflush) solution at last.Thereafter, the well recovery operation, the scale preventative in the reservoir is emitted and is dissolved in the fluid in the reservoir, makes production fluid contain some scale preventatives.Scale preventative prevents or reduces the production fluid fouling in other equipment that pipeline and fluid flow through usually.
Scale preventative can be injected into the underwater well with relevant header (it upwards is delivered to surperficial facility with the extraction fluid from underwater well usually) by exploitation pipeline or flowline (it can comprise marine riser) from the surperficial facility of for example offshore platform or floating production, oil storage and unloading system (FPSO).In this case, the production flow by marine riser stops.Subsequently, scale preventative is pumped into the riser top that is arranged in surperficial facility place and be pumped into underwater well and deliver to submarine reservoirs by marine riser.Because with exploitation flowline and/or the relevant bigger friction of scale preventative viscosity (it is increasing with the temperature reduction near the place, seabed), for the low rate of pumping of the common needs of scale preventative.In some cases, can use a large amount of scale preventatives.For example, the exploitation flowline of typical 15km has 5000 barrels volume according to diameter, and the whole volume of flowline was full of before scale preventative begins to flow into reservoir.In addition, in some cases, flowline need be carried out emptying and cleaning by the pigging operation before chemical inhibitor pumps into well, and with the residue of avoiding being present in the flowline, for example incrustation scale, paraffin and/or sand pump are delivered in the stratum.
When the subsea production system of different satellite wells pooled together in header or flowline, it is expensive that scale preventative squeeze treatment meeting becomes.In this case, because flowline will be used to carry scale preventative, also must closeall well even have only a well to handle.By being provided, the independent pipeline from each well to surperficial production facility can avoid above-mentioned shortcoming; Yet, because engineering restriction or investment spending restriction use dedicated pipeline always not possible.In some cases, sometimes utilize water surface ship, for example diving support vessel (DSV) and the flexible pipe line that is attached on the header are under water carried out squeeze treatment under water.Can carry out squeeze treatment under water by the inhibitor of encapsulated is put into well head.In this case, diving support vessel can transport capsule, and capsule drops in the collecting tank via flexible marine riser by self gravitation.Because the scale preventative diffusion takes place in concentration gradient missionary society.
The operation of even now is successfully used to scale preventative squeeze treatment under water, still needs to be used for to carry material to underwater well, for example is used for the improved system and method for the chemicals of scale preventative squeeze treatment.This system and method should use with can't help the passage that marine riser limits, for example, make that scale preventative squeeze treatment under water can be with the extraction fluid evacuation in the marine riser or make under the situation of the fluid flow inversion in the marine riser and carry out, and should in the system that comprises several wells that are attached on the public exploitation flowline and/or production tree, use.

The specific embodiment
Describe the present invention more fully referring now to accompanying drawing, wherein shown a part of the present invention but non-whole embodiment.In fact, the present invention can implement and should not be construed as and be confined to the embodiments described herein according to many different modes; On the contrary, providing these embodiment is in order to make the present invention satisfy the legal requirements that is suitable for.The member that identical numeral is identical.
With reference now to accompanying drawing especially Fig. 1,, shown schematically to be used for that the chemicals that for example is used to carry out the scale preventative squeeze treatment is delivered to the system 10 of underwater well 12 with material.System 10 generally includes a plurality of pumping units 14,16 by the multiple stage pumping structural configuration, is used for material is delivered to submarine site 22 and material is injected into well 12 by tubular articles 24 from one or more container 18 that is positioned at surperficial facility 20.
First order pumping unit 14 receives material and the tubular articles 24 by stretching out from surperficial facility 20, and for example umbilical is pumped to submarine site 22 with material.Especially, as shown in Figure 1, tubular articles 24 can extend to and be positioned at submarine site 22, for example is positioned at or is close to the second level pumping unit 16 at 26 places, seabed.Tubular articles 24 defines and is used for one or more passage that material flows.First order pumping unit 14 typically is higher than material atmospheric pressure but is not enough to material is transported in well 12 and the reservoir being delivered to pumping unit 16, the first pressure in the second level under first pressure by tubular articles 24.Will be appreciated that material pressure can reduce to the outlet 30 of the tubular articles 24 that is positioned at second level pumping unit 16 places from the inlet 28 of the tubular articles 24 that is positioned at first order pumping unit 14.For example, material can approximately be stored in the container 18 under the atmospheric pressure, and first order pumping unit 14 can be increased to pressure big pressure and carry materials to pass through tubular articles 24, and material can more offer second level pumping unit 16 under the high pressure.
First order pumping unit 14 can be by power source 32, and for example power supply or hydraulic power supply provide power.The operation of power source 32 and first order pumping unit 14 can be by controller 40, for example is configured to receive from operator's artificial input and/or the computer installation control operated according to the program with the order that pre-determines and stipulate and parameter.Controller 40 and power source 32 can also be used to control other parts of the system 10 that comprises second level pumping unit 16 and/or provide power to it.In some cases, controller 40 can be high pressure insertion type control system unit.
The second level pumping unit 16 that is positioned at submarine site 22 is connected to tubular articles 24 and passes through the material that tubular articles 24 receives from first order pumping unit 14.Second level pumping unit 16 raises the pressure of material and material is injected under second pressure in the well 12, and described second pressure is higher than first pressure that is obtained by first order pumping unit 14.
Multiple stage pumping of the present invention system 10 can utilize the pressure that is enough to be used in injecting that material is offered well 12, and the remainder in system 10 provides relatively limited pressure to material simultaneously.For example, if first order pumping unit 14 is operated under the situation that does not have second level pumping unit 16, in tubular articles 24, need bigger pressure to provide enough pressure in the well 12 for material is injected into position 22 under water.Typically, first order pumping unit 14 need to material provide high at least to tubular articles 24 inlet 28 and export 30 between pressure drop and be injected into required pressure sum in the underwater well 12.In some cases, for example, at tubular articles 24 are umbilical or low-pressure hose or the pipes that have than minor diameter, and/or tubular articles 24 be used for that the deep-sea is used or the situation of the long member of others under, bigger along the pressure drop ratio of the length of tubular articles 24.In this case, inlet 28 places of tubular articles 24 be used for resisting on the tubular articles 24 pressure drop and under water 22 places, the position required pressure that is used to be injected into well 12 required pressure sums can surpass the intensity of tubular articles 24.Therefore, for the single stage pump system, need to give tubular articles 24 to provide high strength to resist required high pressure and/or to provide than major diameter so that pressure drop can be very not big to tubular articles 24.
On the other hand, the second level pumping unit 16 that is arranged on submarine site 22 places and is in tubular articles 24 downstreams can be used for pressure is elevated to the level that is enough to be injected in the well, makes the level of pressure limit within the performance constraint of tubular articles 24 in the tubular articles 24.Like this, the pressure that offers the material of tubular articles 24 by first order pumping unit 14 is enough to resist the pressure drop on the tubular articles 24, but less than the pressure drop on the tubular articles 24 and under water 22 places, position be injected into required pressure sum in the well 12.Therefore, be enough to use and have than low-intensity and/or than the tubular articles 24 of minor diameter.Even in use at the very long deep-sea of tubular articles 24, the intensity of umbilical and size are enough to the adaptation material flow and keep the required pressure of flow of material.For example, tubular articles 24 can be configured to have the intensity greater than the pressure drop in the tubular articles 24, makes tubular articles 24 to bear and carries the required pressure of material; Yet tubular articles 24 can be configured to have the intensity less than pressure drop on the tubular articles and injection underwater well 12 required pressure sums.Especially, in some cases, tubular articles 24 can be configured to provide 15000psi or following burst strength, and material can provide to the maximum pressure of 5000psi with 3000psi in tubular articles.
For example, tubular articles 24 shown in Figure 1 is flexible umbilicals, and the cross section of umbilical further specifies in Fig. 2.Umbilical is synthetic cable, and it comprises oversheath 42, and this oversheath holds a plurality of longitudinal members or functional part, pipe or the flexible pipe that is formed by thermoplastic or steel or other metal for example, cable or optical cable, reinforcement etc.For example, as shown in Figure 2, umbilical comprises hollow cylindrical tube 44a, 44b, 44c, and it defines the tubular conduit 46 that is used for carrying chemicals or other material between surperficial facility 20 and submarine site 22.For example, scale preventative squeeze note operating period carries scale preventative or operates delivering hydraulic fluids etc. for other under water can to use one or more tubular conduit 44a, 44b, 44c.Umbilical also comprises the communications cable 48, and it can be by electric conductor or optical conductor, and the copper core of for example solid or twisting or aluminium cable or optical fiber cable are made.The communications cable can be used for transmission of control signals, transmits electric power and/or is used for information (as the information of being collected by the sensor that is positioned at submarine site 22 places or other device) communication.Cable can be contained in the sheath of being made by plastics or other protective materials 50.Reinforcement 52 can be formed and be used to improve the intensity and/or the rigidity of umbilical by steel, composite material etc.In addition, in the oversheath 42 other member or material can be set.For example, in some cases, the space 54 between the different component in the sheath 42 can be full of plastic material or other material to improve intensity, buoyancy, rigidity or the sealing of umbilical.
