Description
Technical field:
The present invention relates to a kind of oil well pump for sanding heavy crude oil well, particularly a kind of notes are adopted integrated sand-proof oil-well pump.
Background technique:
At present, the steam injection heating exploitation is one of main mining type of thick oil well, on-the-spot thick oil well need be lowered to steam injection string usually earlier and carry out gas injection in implementing the heat extraction by steam injection process, behind the oil well steam soak, use directly suction well liquid from oil well of conventional oil well pump, must wait do not have pressure after, tripping out the gas injection tubing string could descend the pump commentaries on classics to take out, so not only increase the work operations amount, prolong the construction operation cycle, and missed the most favourable commentaries on classics extraction oil phase, and then make oil layer pollution, reduced oil well output.Prolongation along with the viscous crude injection thermal recovery time, the sand production situation is on the rise, and sand content is also more and more in the crude oil, and in use often sand card, sand bury to cause oil well pump, significantly reduced the working life of oil well pump, its stable yields and normal exploitation have been constituted adverse effect.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of notes and adopts integrated sand-proof oil-well pump, and this device has been realized variorum gas, oil recovery, the multiple function of sand control in one, reduces the underground work workload, prevents that effectively sand card, sand from burying.Having overcome prior art need trip out the gas injection tubing string earlier and could descend pump to change extraction oil and the deficiency that sand card, sand bury often occurs in oil recovery process.
The technical solution used in the present invention is: a kind of notes are adopted integrated sand-proof oil-well pump, and plunger, plunger valve cover, travelling valve gland place in the pump barrel, and plunger valve cover is connected with plunger; Travelling valve gland upper end connects the travelling valve cover, and the lower end connects pump barrel; Travelling valve cover upper end connects the hollow stem short circuit, and the hollow stem short circuit places in the upper connection; Upper connection, box cupling I, overcoat, joint I, joint II, pipe nipple, joint III, joint IV, lower contact connect in turn; Box cupling I spigot is connected with box cupling I, and the pump barrel outside is set with the pump barrel sheath, the pump barrel sheath, bump the pump cap, overcoat connects in turn; Plunger, joint I, interior pipe connect in turn, are provided with connecting rod in the joint I, linkage connector, connecting rod, bump the pump short circuit head, bump the pump pipe nipple, bump the lower contact of pump pipe nipple and connect in turn; Bump the lower contact of pump pipe nipple and be connected with the steel wire loop joint by wire rope I, wire rope II, wire rope I, wire rope II are on pulley, and pulley is contained on the pulley spindle, and pulley spindle is contained on the pulley base; Steel wire loop joint, head sub, box cupling II, valve connecting rod spheroid, ball valve, valve connecting rod connect in turn; Valve connecting rod spheroid is equipped with heavy body metal outward, and heavy body metal is equipped with protecting jacket outward, on protecting jacket and the heavy body metal end cap is housed; Be connected with valve spring holder, therapeutic method to keep the adverse qi flowing downward croquet valve, valve connecting rod section header on the valve connecting rod, valve connecting rod section header, following pipe nipple head, stuffing box gland connect successively; Last valve ball seat, cotter seat, therapeutic method to keep the adverse qi flowing downward croquet seat are connected, and are sleeved on the valve connecting rod outside.
The invention has the beneficial effects as follows: the present invention is owing to adopted the device that control gas injection channel switch is installed under pump barrel, thereby have the gas of variorum, oil recovery, the multiple function of sand control in the effect of one, utilize it can be when sanding heavy crude oil well be produced the immobile oil tubing string, has only needed alternately to finish gas injection oil recovery production under the situation of lower sucker rod, reduced the underground work workload, take full advantage of the favourable oil recovery phase, prevent that thereby oil layer pollution from reaching raising injection efficiency and crude output, and efficiently solve the problem that prevents that sand card, sand from burying.
