Abstract
A long plunger type injection-production pump comprises an adapter 1, a pump cylinder 2, a fixed valve 3, a downstream traveling valve 4, a plunger 5 and an upstream traveling valve 6 and is characterized in that the adapter 1 of the long plunger type injection-production pump is of a cylindrical reducer structure provided with inner threads at the upper and lower ends, the inner threads at the lower end are connected with the pump cylinder 2, the fixed valve 3 is arranged at the bottom end of the pump cylinder 2, the upstream traveling valve 6 and the downstream traveling valve 4 are arranged at the upper and lower ends of the plunger 5, and the plunger 5 is installed in the pump cylinder 2. The long plunger type injection-production pump is suitable for a conventional thickened oil steam huff and puff exploitation technology, is high in injection-production efficiency and can achieve quick rotary pumping after blowout, avoid chilling damage caused by killing and flushing well operation to an oil layer, increase oil well yield, reduce the oil well operation cost and reduce the labor intensity of operators.
Description
Technical field
the utility model relates to oilfield exploitation down-hole pumping unit, specifically a kind of long-plunger type injection-extraction pump.
Background technique
conventional Heavy Oil cyclic steam stimulation technique: steam injection-stewing well-open flow-compress and wash well-lower pump-open and take out.The problem existing is: after open flow, can not turn and take out as early as possible, shorten peak productive life; Compress and wash well to formation damage, reduce oil reservoir heating effect, not only affect oil well output, and increase oil well operation expense, increase the labor intensity of operating worker.
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 long-plunger type injection-extraction pump is provided.
technical solutions of the utility model: comprising: crossover sub, pump barrel, standing valve, lower travelling valve, plunger, upper travelling valve.The crossover sub of described long-plunger type injection-extraction pump is cylindrical shape CONCENTRIC REDUCER structure, upper and lower end is equipped with internal thread, upper end is connected with oil pipe, lower end internal thread is connected with pump barrel, the bottom of pump barrel is provided with standing valve, plunger upper and lower end is respectively equipped with upper travelling valve and lower travelling valve, is arranged in pump barrel, and plunger upper end is connected with sucker rod.
pump barrel top in above-mentioned long-plunger type injection-extraction pump is provided with steam injection hole.
the beneficial effects of the utility model are: be applicable to conventional Heavy Oil cyclic steam stimulation technique, it is high that note is adopted efficiency, after open flow, can realize fast and turn and take out, avoid operation to compress and wash well to formation damage, increase oil well output, reduce oil well operation cost, alleviate the labor intensity of operating worker.
Brief description of the drawings
fig. 1-on-the-spot application structure schematic diagram of the present utility model.
in figure, 1. crossover sub, 2. pump barrel, 3. standing valve, 4. lower travelling valve, 5. plunger, 6. upper travelling valve, 7. rod string, 8. oil pipe; C. steam injection hole.
Embodiment
by reference to the accompanying drawings, the utility model will be further described:
long-plunger type injection-extraction pump is made up of crossover sub 1, pump barrel 2, standing valve 3, lower travelling valve 4, plunger 5, upper travelling valve 6.The crossover sub 1 of described long-plunger type injection-extraction pump is cylindrical shape CONCENTRIC REDUCER structure, upper and lower end is equipped with internal thread, upper end is connected with oil pipe 8, lower end internal thread is connected with pump barrel 2, the bottom of pump barrel 2 is provided with standing valve 3, and top is provided with steam injection hole C, and plunger 5 upper and lower ends are respectively equipped with upper travelling valve 6 and lower travelling valve 4, be arranged in pump barrel 2, plunger 5 upper ends are connected with sucker rod 7.
when steam injection, above carry rod string 7, plunger 5 is mentioned in oil pipe 8, and annular space and the pump barrel 2 top steam injection hole C UNICOMs of plunger 5 and oil pipe 8 form steam injection passage, realize steam injection.
turn while taking out, transfer rod string 7, plunger 5 resets, the steam injection hole C on sealing pump barrel 2, and steam injection pathway closure, adjusts over-stroke, and polished rod is connected with rope hanger, gets final product opening well and making production.
