Description
Technical field:
The utility model relates to a kind of downhole hardware that oil field pumping well is produced that is used for, and belongs to the oil tool class.
Background technique:
So far for a long time, tubing pump is that the most general a kind of downhole pump is adopted in the oil field pumping well exploitation always, and this kind oil well pump has its characteristics and advantage, can satisfy the needs of most pumping well ordinary production basically.Yet also there is following problem from following pump in this kind oil well pump to well repairing and pump checking:
1, in following pump process,, some sand grains can be brought in the pump line because oil pipe or sucker rod are cleared up thoroughly or managed down in the way of bar, sink at the bottom of the pump, this brings hidden danger just for the pump detection and workover success rate, makes the pump efficiency reduction even causes holddown, causes the serious consequence of secondary operation;
2, the plunger of common oil well pump because the influence of certain factor is stuck in the pump barrel ingress sometimes, can't enter in the pump barrel, makes the oil well pump cisco unity malfunction, thereby causes secondary operation;
3, when playing pump line, have a large amount of profits in the pump barrel, increased the difficulty of job execution, the factor that influences safety, quality increases, and makes construction period prolong, and cost of production increases, and pollutes to well site and surrounding enviroment.
Summary of the invention:
The utility model purpose is to provide a kind of draining type sand-proof oil-well pump that can improve the pump detection and workover one-time success rate, help improving construction safety, quality, environmental protection.
The utility model is to realize like this.This kind oil well pump by box cupling, standing valve cover, standing valve ball, ball seat under tubing coupling, pump barrel, draining switch, the pump barrel, compress box cupling, on move about valve ball, ball seat, travelling valve cover, valve ball, ball seat, plunger, pressure cap, docking adapter male, seal ring are formed down, the pump barrel upper and lower end is connected with box cupling under the pump barrel with tubing coupling with screw thread respectively, the box cupling lower end is connected with the standing valve cover with screw thread under the pump barrel, standing valve cover lower end with screw thread with compress box cupling and be connected; The pump barrel sidewall is provided with the draining switch, and the pump barrel internal upper part is equipped with the docking adapter male, in the seal groove seal ring is housed therebetween; Plunger is housed in the pump barrel, and the plunger upper end is connected with the docking adapter male, and the lower shoulder upper and lower is respectively equipped with the valve ball that moves about, ball seat and following travelling valve cover, valve ball, ball seat on the plunger inner headed face; Standing valve cover and compress and be provided with the standing valve ball seat between the box cupling which is provided with the standing valve ball.During pump detection and workover, this oil well pump is connected the tubing string bottom, down to the downhole designs degree of depth, the rod string that then bottom is connected with the docking adapter female is lowered in the tubing string; When the docking adapter female is soon docked with the docking adapter male on this oil well pump top, mix up polished rod length, following polished rod when being hampered, (this moment, the docking adapter female achieved a butt joint with male), on carry polished rod, adjust over-stroke and hang oily.During well workover, as long as sucker rod is tripped out, plunger is proposed pump barrel once more, the draining switch just can be opened, and the profit in the pump line is released in pit shaft, thereby avoid well head to pollute, and reaches the purpose of environmental protection, safe construction.
The utility model novel structure, reasonable in design, owing to be respectively equipped with anti-sand launder on plunger and the docking adapter male, the sand grains of falling in the pump line in the time of can be with construction is controlled at more than the pump barrel, works plunger working stability when taking out, and sand control capability strengthens; Because the pump barrel sidewall is provided with the draining switch, can prevent effectively that well head from polluting, and reaches raising pump detection and workover one-time success rate and environmental protection, purpose of safety.
