201. and acquiring the arrangement position, the orientation and the model of the drilling equipment according to the area of the well site.
In this step, the well site may be a well site storing unconventional oil and gas resources represented by shale oil and shale gas. Since the land acquisition for oil field construction is difficult, the development of the well site needs to be changed to a multi-layer three-dimensional development, and the land utilization efficiency of the well site needs to be improved by improving the well site arrangement method.
The well head position is preliminarily planned according to the determined area of the well site which can be developed, for example, it may be preset that the well heads are arranged in one or more rows and the drilling equipment of one row of well heads is arranged in a direction coaxial with the direction of the row of well heads at a time of construction, and when the drilling equipment is initially placed in the well site, it is placed at the well head position at the edge of the well site in the plan, so that after the first well head is drilled, other well heads are drilled by moving the drilling equipment in the same direction each time, and the well heads drilled in the construction are arranged in a row.
202. Based on the model of the drilling equipment, obtaining the size of the drilling equipment, wherein the size of the drilling equipment comprises half of the length and half of the width of the drilling equipment.
Wherein, the size of the drilling equipment can be obtained by a nameplate of the equipment or an instruction for using the equipment.
203. Based on the size of the drilling equipment, half the length and half the width of the area required for drilling construction are obtained.
Please refer to fig. 3, L in fig. 3 1 Representing half the length of the area that the drilling construction needs to occupy, D in figure 3 1 Indicating that drilling operations require half the width of the area.
204. And acquiring the arrangement position, orientation and model of the fracturing equipment according to the area of the well site.
The fracturing construction is an important technical measure for increasing the yield of an oil and gas well and increasing the injection of a water injection well, is widely applied to low-permeability oil and gas reservoirs, and has good effect in the yield increase transformation of medium-high permeability oil and gas reservoirs. The method is characterized in that a ground high-pressure pump set is utilized, high-viscosity liquid is injected into a well with a discharge capacity greatly exceeding the stratum absorption capacity, high pressure is suppressed at the bottom of the well, when the pressure is greater than the ground stress near the well wall and the tensile strength of stratum rocks, a crack is generated in the stratum near the bottom of the well, sand carrying liquid with a propping agent is continuously injected, the crack extends forwards and is filled with the propping agent, and the crack is closed on the propping agent after the well is closed, so that a sand filling crack with a certain geometric size and high flow conductivity is formed in the stratum near the bottom of the well, and the purpose of increasing the production and the injection of the well is achieved.
In this step, according to the area of the well site and the planning of the drilling construction in the well site arrangement, the fracturing construction may be planned, that is, the arrangement position, the orientation, and the model of the fracturing equipment are set, for example, the fracturing equipment may be configured to fracture in a direction perpendicular to the drilling construction direction, or other arrangement manners may be adopted according to actual needs, which is not limited in this embodiment.
205. Based on the model of the fracturing equipment, the size of the fracturing equipment is obtained, and the size of the fracturing equipment comprises a fracturing equipment central angle corresponding to the fracturing equipment.
The central angle of the fracturing equipment corresponding to the fracturing equipment can be obtained according to a nameplate or a use instruction of the equipment or can be obtained according to production experience summary, and the central angle is not limited in the embodiment.
206. And acquiring the central angle of the area required to be occupied by the fracturing construction based on the size of the fracturing equipment.
The cross section of the zone of influence of the fracturing treatment on the formation is a sector, see the fracturing work zone 4 in fig. 3, the central angle of the fracturing work zone 4 being alpha.
207. And acquiring the minimum distance between the drilling equipment and the fracturing equipment during synchronous construction based on the half of the length, the half of the width, the central angle, the preset additional safety distance between the drilling equipment and the fracturing area and a relation 1.
In the formula, L represents the minimum distance between drilling equipment and fracturing equipment during synchronous construction, and m;
d represents an additional safe distance between the well and the fracture zone, m;
alpha represents the central angle of the area required to be occupied by the fracturing construction;
L 1 the length of a region required to be occupied by drilling construction is represented by m;
D 1 representing half the width of the area, m, that the drilling construction needs to occupy.
The following describes the above relation 1 with reference to fig. 3:
In the construction process, the wellhead spacing represents the distance between two adjacent wells, based on the minimum spacing between the drilling equipment and the fracturing equipment during synchronous construction and the design wellhead spacing, the quotient obtained by dividing the minimum spacing by the wellhead spacing is the minimum spacing well number of the drilling and fracturing synchronous operation, and therefore the construction sequence of the working operation is integrally planned.
The minimum distance between the drilling equipment and the fracturing equipment can be obtained according to drilling and fracturing experience based on synchronous construction, or set according to the requirements of the drilling equipment and the fracturing equipment, which is not limited in this embodiment.
The additional safety distance between the drilling well and the fracturing area may be obtained according to drilling and fracturing experience, or may be set according to requirements of drilling equipment and fracturing equipment, which is not limited in this embodiment.
The step is explained by taking the fracturing equipment as an example, which can perform fracturing construction along the direction vertical to the drilling construction direction, if the fracturing equipment adopts other arrangement modes, corresponding allowance is set when the setting position and other construction dimensions of the fracturing equipment are determined, so that the additional safety distance D between a drilling well and a fracturing area in the construction process can meet the safety requirement of construction.
208. After a plurality of well mouths are drilled in the drilling construction, when the distance between any well mouth and the drilling equipment is smaller than the minimum distance, fracturing construction is carried out on any well mouth by adopting fracturing equipment.
In one possible implementation, the fracturing apparatus performs fracturing operations in a direction perpendicular to the direction of drilling operations. The well drilling construction can be continuously carried out while the fracturing construction is carried out, namely, the well drilling construction and the fracturing construction are carried out simultaneously, and based on the steps, an additional safety distance between the well drilling and the fracturing area is reserved, so that the areas of the well drilling construction and the fracturing construction do not coincide, namely, the well drilling construction and the fracturing construction do not influence each other, and the construction efficiency can be improved.
The fracturing construction can adopt an independent fracturing technology, and can also adopt a zipper type fracturing technology or a synchronous fracturing technology.
In particular, individual fracturing is the fracturing of each well individually, stage by stage. The zipper type fracturing is characterized in that two horizontal well mouths which are parallel and close to each other are connected to share one set of fracturing truck set, 24-hour uninterrupted alternate staged fracturing is carried out, and staged and perforating operation is carried out on one well while fracturing on the other well. Synchronous fracturing is that two wells fracture simultaneously, and two wells carry out cable bridge plug operation simultaneously in addition, and the ageing is higher, but must possess two sets of fracturing unit, and is with high costs. The zipper type fracturing technology is a main mode of industrial fracturing, fracturing of any number of sections can be achieved, waiting time between sections is 2-3 hours, and work such as equipment maintenance and fuel addition can be completed by utilizing the gap, so that the zipper type fracturing technology is particularly suitable for industrial fracturing.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
The well site construction method provided by the embodiment of the application comprises the steps of obtaining the minimum distance between the drilling equipment and the fracturing equipment during synchronous construction based on the size of the drilling equipment, the size of the fracturing equipment, the additional safety distance between a preset drilling area and the fracturing area and the relation 1, and arranging the drilling equipment and the fracturing equipment conveniently, namely, in the construction process, after a plurality of well mouths are drilled in the drilling construction based on the minimum distance, and when the distance between any well mouth and the drilling equipment is smaller than the minimum distance, fracturing construction is carried out on any well mouth by adopting the fracturing equipment.
Aiming at the current situations of limited construction land and short construction period, the technical scheme can greatly save development land, shorten construction speed and meet the requirement of 'multilayer three-dimensional development' of unconventional oil and gas resources.
