Abstract
An extract oil circulation injection and extraction device comprises a connector (1), an oil pumping plunger (2), a pump cylinder (3), a sealing plunger (4), a circulation valve (5) and a baffle (6). The extract oil circulation injection and extraction device is characterized in that internal threads are arranged at the upper portion of the pump cylinder (3) of the extract oil circulation injection and extraction device, the sealing plunger (4) is arranged in the pump cylinder (3), the oil pumping plunger (2) is arranged between the upper portion of the sealing plunger (4) and the pump cylinder (3), the circulation valve (5) is arranged at the lower portion of the sealing plunger (4), and the baffle (6) is arranged at the upper portion of the circulation valve (5). The extract oil circulation injection and extraction device is used for injection and extraction, the phenomena that cold damage happens to oil layers, scaling occurs in pipelines, and the plungers are stuck are avoided, working cost is reduced, the injection and extraction efficiency is improved, and normal production of an oil well is ensured.
Description
Technical field
the utility model relates to oil field well injection-extraction pump kind equipment, specifically a kind of oil recovery circulation injection-recovery apparatus.
Background technology
oil well, in recovery process, due to down-hole complex geologic conditions, need to carry out steam injection, water filling to oil reservoir, and conventional oil well pump, can not turn and take out as early as possible after open flow at present, has shortened peak productive life; Compress and wash well to formation damage, reduce oil reservoir heating effect, increase operating cost; During the vexed well of steam injection, often occur pipeline scale, plunger is prone to stuck phenomenon, cannot normally move, and causes note to adopt Efficiency Decreasing, affects the normal production of oil well.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of oil recovery circulation injection-recovery apparatus is provided.
technical solutions of the utility model comprise: joint, oil-pumping plunger, pump barrel, sealed plunger, circulation valve, baffle plate.The pump barrel top of its oil recovery circulation injection-recovery apparatus is provided with internal thread, is provided with sealed plunger in pump barrel, between sealed plunger top and pump barrel, is provided with oil-pumping plunger, and the bottom of sealed plunger is provided with circulation valve, and circulation valve top is provided with baffle plate.
sealed plunger top in above-mentioned oil recovery circulation injection-recovery apparatus is provided with pressed on ring discharge orifice.
baffle plate in above-mentioned oil recovery circulation injection-recovery apparatus is provided with centre bore and lower circulation hole.
operating principle: during steam injection, above carry rod string, oil-pumping plunger leaves pump barrel, and sealed plunger leaves circulation valve, the lower circulation hole on circulation valve sealing plate is as steam injection passage steam injection.During oil pumping, transfer rod string, oil-pumping plunger and sealed plunger reset, and start oil pumping.
the beneficial effects of the utility model are: note is adopted dual-purpose, avoids formation damage, pipeline scale, and seizure of plunger phenomenon reduces operating cost, improve note and adopt efficiency, and assurance oil well is normally produced.
Accompanying drawing explanation
the main complete section structural representation of looking of the on-the-spot application of Fig. 1-the utility model;
the master of Fig. 2-baffle plate 6 looks complete section structural representation;
in figure, 1, joint, 2, oil-pumping plunger, 3, pump barrel, 4, sealed plunger, 5, circulation valve, 6, baffle plate, 7, oil pipe, 8, sucker rod; A. pressed on ring discharge orifice, circulation hole under B., C. centre bore.
The specific embodiment
by reference to the accompanying drawings, the utility model will be further described:
oil recovery circulation injection-recovery apparatus is comprised of joint 1, oil-pumping plunger 2, pump barrel 3, sealed plunger 4, circulation valve 5, baffle plate 6.Pump barrel 3 tops of its oil recovery circulation injection-recovery apparatus are provided with internal thread and are connected with tubing string 7, in pump barrel 3, be provided with sealed plunger 4, between sealed plunger 4 tops and pump barrel 3, be provided with oil-pumping plunger 2, the bottom of sealed plunger 4 is provided with circulation valve 5, circulation valve 5 tops are provided with baffle plate 6, and sealed plunger 4 tops are connected with sucker rod 8.
