Abstract
The oil-gas separation under well of oil well pump, by flat oil pipe, II grades of separators, I grades of separators, packers, oil pipe length adjuster, loss of gas piecings, oil well pump make up, solve the oil-gas separation of oil well oil recovery under well, because of having adopted I grades of separators, II grades of separators, thus raise the oil-gas separation efficiency, raise the pumping efficiency of the oil well pump, has improved the output of the oil well, this apparatus is applied to the oil recovery low yield well and many gas oil wells of many years.
Description
Technical field: oil-well pump of oil well downhole oil air separation is to be applied to oil field petroleum recovering operation, makes the device of Oil-gas Separation in particular for down-hole oil production.
Background technology: at present, oil well is along with year by year oil recovery, strata pressure descends, escaping gas can not effectively be discharged from fluid, gas is the one of the main reasons that influences the oil well pump pump efficiency, especially many gas wells are bigger to the oil well pump influence, because gas enters in the pump, make oil well pump oil-feed valve postpone to open, even close, thereby reduced the oil well pump pump efficiency, caused oil well output to descend, for solving gases affect pump efficiency problem, extensive use gas anchor in oil field carries out Oil-gas Separation, because the restriction of structure accumulates in below the packer gas of separating, and can not enter in the oil jacket annular space on packer top, especially gas gathers when too much and mixes with oil stream again, oil gas separation is not obvious, makes oil well pump be in the inefficient operation state, and oil well output descends.
Summary of the invention: the purpose of this invention is to provide a kind of raising down-hole oil gas separative efficiency, improve the oil well pump pump efficiency, improve the oil-well pump of oil well downhole oil air separation of oil well output, above-mentioned purpose is to realize by following technical scheme: oil-well pump of oil well downhole oil air separation, comprise plain end oil well pipe, oil well pump, it is characterized in that between plain end oil well pipe and oil well pump, installing successively II level eliminator, I level eliminator, packer, tubing length adjuster, ease gas joint; II level eliminator is connected with plain end oil well pipe, and I level eliminator is connected with II level eliminator, and packer is connected with I level eliminator, and the tubing length adjuster is connected with packer, and ease gas joint is connected with the tubing length adjuster, and ease gas upper end of joint is connected with oil well pump.
Operating principle: when fluid is rising when II level eliminator oilhole enters II level eliminator on the down-hole, part gas separates from fluid, the fluid that enters II level eliminator enters the space between sleeve pipe and outer layer sleeve of separating of I level eliminator through separating sleeve pipe upper end oilhole and oilhole in the top connection, fluid rises to the packer place, under the big effect of fluid density, fluid flows downward, enter I level eliminator inner chamber through oil-through hole, pass through packer, the tubing length adjuster, the oilhole at ease gas joint center enters oil well pump, when fluid rises when flowing downward again at I level eliminator, gas secondary separation in the fluid, isolated gas is through packer, the tubing length adjuster, pore on the ease gas joint is discharged in the oil jacket annular space.
Advantage of the present invention is: because adopted I level, II level eliminator, and make isolated gas pass through packer, pore on tubing length adjusting, the ease gas joint enters in the oil jacket annular space, has reduced the gas content in the fluid, thereby has improved the pump efficiency and the oil well yield of oil well pump.
Description of drawings: Fig. 1 is oil-well pump of oil well downhole oil air separation structural representation (solid arrow is the fluid flow direction, and empty arrow is a gas flow direction).
The specific embodiment: oil-well pump of oil well downhole oil air separation comprises plain end oil well pipe 1, II level eliminator 5, I level eliminator 10, packer 11, tubing length adjuster 14, ease gas joint 16, oil well pump 17, II level eliminator 5 is connected with plain end oil well pipe 1, II level eliminator 5 is by outer tube 2, separator tube 22, top connection 6 constitutes, separator tube 22 is connected with outer tube 2, install joint 6 on the separator tube 22, make oilhole 3 on the outer tube 2, pore 4, oilhole 21 is made in separator tube 22 upper ends, make oilhole 23 in the top connection 6, I level eliminator 10 is connected with II level eliminator 5, I level eliminator 10 is by separating sleeve pipe 9, outer layer sleeve 8 constitutes, connect into integral body through oilhole 7, packer 11 is connected with I level eliminator 10, oilhole 20 is made at packer 11 centers, around oilhole 20, make pore 12, tubing length adjuster 14 is connected with packer 11, oilhole 19 is made at tubing length adjuster 14 centers, around oilhole 19, make pore 13, ease gas joint 16 is connected with tubing length adjuster 14, the upper end is connected with oil well pump 17, oilhole 18 is made at ease gas joint 16 centers, makes air vent 15 mutually in sidewall and bottom.
