Description
Technical field
The utility model relates to down-hole oil production equipment technology field, oil field, relates to the gas-liquid separator that the oil recovery oil-immersed pump connects especially, is a kind of gas-liquid separator of built-in wax-proof anti-scaling erosion protection system.
Background technology
In the oil exploitation process, the pit shaft of oil well and the inwall of oil-immersed pump tend to produce phenomenons such as wax deposition, fouling and corrosion.Inwall wax deposition, fouling and the corrosion of pit shaft and oil-immersed pump not only have a strong impact on oil well production, and influence the application life of well wellbore and oil-immersed pump.Oil-immersed pump is being born in the oil exploitation process crude oil supercharging in well, and be lifted to the effect on ground, so wax deposition, fouling and corrosion can make the function of the lifting crude oil of oil-immersed pump reduce, even the clogging raw oil flow channel, shorten pump detection period, shorten the application life of oil-immersed pump.
At present, the oil well that use in each oil field and wax control, antiscale and the method for inhibiting corrosion of oil-immersed pump, mainly based on chemical injection, but long-term chemical injection is the cost height not only, and a kind of chemical agent can only play single effect, as single wax control, antiscale or corrosion-resisting function, also there is the compatibility compatibility issue between wax-proofing agent, scale preventative and the anticorrisive agent.Some chemical agent itself has negative interactions such as corrosion to pit shaft and crude oil production facility, and organic class chemical agent also is subjected to such environmental effects such as HTHP and is ineffective.For oil well, promptly be to use chemical agent also to be difficult to obtain the effect of antiscale, scale removal with barium sulfate and Liu Suan Strontium fouling.Also have the physical method of employing and device to carry out single or comprehensive wax-proof anti-scaling anticorrosion, operating distance is short, action time is short, be difficult to put into problems such as down-hole and construction operation expense height but physical method and device exist.The oil-immersed pump intake is between electric pump and motor, and the intake eyelet is positioned on the tube wall, and physics wax-proof anti-scaling erosion protection system is placed on the electric submersible pump bottom, and it is very difficult simultaneously oil well and electric submersible pump being carried out the wax-proof anti-scaling anticorrosion.Reach oil well and electric submersible pump are carried out the etch-proof purpose of wax-proof anti-scaling, just need multiple measures such as employing is given up, packer, Y pipe, kuppe, fluid is flowed through behind the wax-proof anti-scaling anticorrosion physical unit, flow into the oil-immersed pump intake again, not only increased the input cost of downhole tool, and increased down-hole construction operation cost, and because of the servicing unit of these physical units and increase be not the straight tube of hollow entirely, and cause oil well can't carry out electric submersible pump bottom test jobs, limited the use of physics wax-proof anti-scaling erosion protection system.Chinese patent notification number: CN200955384Y provides a kind of " gs-oil separator that is used for electric submersible pump ".
The utility model content
The purpose of this utility model is: a kind of gas-liquid separator of built-in wax-proof anti-scaling erosion protection system is provided, the wax-proof anti-scaling erosion protection system is set in gas-liquid separator, realize simultaneously oil-immersed pump and oil well being carried out the wax-proof anti-scaling anticorrosion.
The technical solution adopted in the utility model is: the gas-liquid separator of built-in wax-proof anti-scaling erosion protection system, mainly form by top connection, urceolus, helical runner, metal ring, central axis and lower contact.Be connected with urceolus at the top connection outer wall, central axis is arranged in urceolus, the top connection centre bore is passed in the upper end of central axis; On the wall of central axis, be fixed with helical runner; The lower end of urceolus is connected on the upper end outer wall of lower contact, and the lower end of central axis is in the centre bore of lower contact; On the outer wall of lower contact, intake is arranged, axial entrance hole, intake and entrance hole UNICOM are arranged around the lower contact centre bore.It is characterized in that: in urceolus and in the bottom of helical runner metal ring is arranged, central axis passes the metal ring centre bore, and the quantity of metal ring is between 2～60, and the distance between adjacent two metal rings is between 10～80 millimeters.Be evenly distributed with axial hole on the metal ring.Axial hole is used for fluid to be passed through, and the gross area of axial hole is according to oil well output design and greater than the design discharge capacity of oil-immersed pump.These axial holes help gas to separate.Metal ring has the wax-proof anti-scaling corrosion proof function.
For preventing metal ring generation axial float, the fixed form of metal ring has two kinds: separation sleeve is fixing to be fixed with circlip for shaft.When adopting separation sleeve fixing metal ring, separation sleeve is arranged in urceolus, separation sleeve is a cylindrical shape, and the upper end of upper isolation cover is fixed on the outer wall of top connection, and the lower end of lower isolation cover is fixed on the upper surface of lower contact.Between per two metal rings a separation sleeve is arranged.When adopting separation sleeve to make the metal ring location, the central axis of metal ring and eliminator is gapped, prevents the eliminator central axis and the metal ring frictional impact of high speed rotating.When adopting circlip for shaft fixing metal ring, on the outer wall of central axis, annular groove is arranged, circlip for shaft has a circlip for shaft respectively in the both sides of metal ring in the annular groove of central axis.When adopting circlip for shaft to make the metal ring location, gapped between metal ring and the eliminator outer tube inner wall, prevent the metal ring and the eliminator urceolus frictional impact of high speed rotating.
The beneficial effects of the utility model: the gas-liquid separator of the built-in wax-proof anti-scaling erosion protection system of the utility model, 1, metal ring has the wax-proof anti-scaling corrosion proof function, can carry out wax control, antiscale, reach anti-corrosion treatment oil-immersed pump and the above pit shaft of oil-immersed pump simultaneously, have good economic worth.2, adopt metal ring along gas-liquid separator central axis arranged in series, simple in structure, processing and easy for installation.3, the connected mode of gas-liquid separator and intake and other parts of oil-immersed pump and size do not change, with the electric pump compatibility of each oil-immersed pump manufacturer production.4, gas after treatment can separate from liquid better, reduces electric pump gas lock and corrosion, improves the application life of pump efficiency, prolongation pump.Therefore, can be widely used in the oilfield exploitation operation.
