Abstract
The utility model relates to a long column stopper sand control card oil -well pump, the delivery valve is installed to the upper end of long column stopper assembly, and the outside of long column stopper assembly is provided with the pump barrel assembly, and the outside of pump barrel assembly is provided with heavy husky outer tube, the bleeder is installed to long column stopper assembly lower extreme, and the bleeder is inside to be provided with the traveling valve, and the standing valve assembly is installed to the bleeder lower extreme. Be applicable to during the sand content is less than 0.8% oil well, the operation of recovering the oil in the great oil well of the mainly used volume of shaking out, adopt comparatively ideal pump barrel assembly of sand control effect and long column stopper assembly structure, the sand setting outer tube has been increased simultaneously, make the oil -well pump the pumping in -process can be fine the partial sand grain that carries crude oil block outside the pump barrel assembly, simultaneously because the effect of sand grain gravity, make the annular space of sand fallout between pump barrel assembly and statement outer tube, the wearing and tearing of pump barrel assembly with long column stopper assembly have been avoided, the sand card, phenomenons such as sand plug, the service life of the oil -well pump is prolonged.
Description
Technical field
The utility model belongs to pumping unit technical field, particularly relates to a kind of long plunger sand control card oil well pump.
Background technique
At present, along with continually developing of oil well, shaking out of many loose sand oil accumulations is on the rise, moisture rising and surging of liquid-extracting amount make sand production more aggravate, a large amount of oil wells is caused to affect normal production because sand card oil well pump or sand bury sucker rod, at the bottom of oil well production efficiency, some oil well production will carry out pump detection and workover in several days, and the scrappage of oil well pump is high; Gudao oilfield is because of sand card, and the oil well pump that scuffing of cylinder bore lamp reason is scrapped accounts for more than 30% of oil well pump sum, causes the significant wastage of manpower and materials, has had a strong impact on the production of crude oil.
Model utility content
The utility model provides the long plunger sand control card oil well pump that a kind of structure is simple, easy to install, increase work efficiency for solving in known technology the technical problem that exists.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
This long plunger sand control card oil well pump comprises: outlet valve, pump barrel assembly, long-plunger assembly, desilting outer tube, standing valve assembly, traveling valve, pump barrel;
The upper end of long-plunger assembly is provided with outlet valve, and the outer installment of long-plunger assembly has pump barrel assembly, and the outer installment of pump barrel assembly has desilting outer tube; Long-plunger assembly lower end is provided with oil drainer, and oil drainer inside is provided with traveling valve, and oil drainer lower end is provided with standing valve assembly.
The utility model can also adopt following technical measures:
Gap is provided with between described long-plunger assembly and desilting outer tube.
The length of described long-plunger assembly is corresponding with the length of pump barrel assembly.
During upstroke, standing valve assembly is opened, and traveling valve cuts out, and fluid enters in pump barrel assembly by the oil drainer oil inlet hole on the standing valve assembly of bottom; During down stroke, standing valve cuts out, and traveling valve is opened, and the fluid of pump barrel assembly cavity of resorption enters pump barrel assembly and oil pipe by traveling valve, long-plunger assembly inner chamber, so repeatedly fluid constantly can be transported to ground.
The advantage that the utility model has and good effect are: this long plunger sand control card oil well pump is applicable to sand content and is less than in the oil well of 0.8%, be mainly used in oil producing operation in the larger oil well of sand production rate, the pump barrel assembly adopting sand controlling result ideal and long-plunger assembly structure, add sand setting outer tube simultaneously, the part sand grains making oil well pump can be good at crude oil to carry in pumping process is blocked in outside pump barrel assembly, simultaneously due to the effect of sand grains gravity, make in the annular space of sand fallout between pump barrel assembly and statement outer tube, avoid the wearing and tearing of pump barrel assembly and long-plunger assembly, sand card, the phenomenons such as sand plug, improve the working life of oil well pump.
