Abstract
The invention discloses an oil well pump for oil exploitation. The oil well pump comprises a motor, a transmission shaft, a screw and a pipe body. The motor is arranged on the pipe body. A sealing cover is arranged between the motor and the pipe body. The transmission shaft is arranged on the lower portion of the motor and is in transmission connection with the motor. The screw is arranged in the pipe body and fixedly connected with the transmission shaft. An impeller is arranged at the tail end of the screw and fixedly connected with the screw. The inner side of the pipe body is arranged in a corrugated manner. Sealing cavities are formed between the pipe body and the screw and distributed at equal distance. A filter screen is arranged at the bottom of the pipe body. The oil well pump for oil exploitation is simple in structure, high in oil pumping efficiency and good in running stability.
Description
Technical field
The present invention relates to a kind of oil exploitation oil well pump.
Background technology
Oil well pump refers to be driven downhole hardware crude oil in well being given rise to ground by oil pumper, and common oil well pump is mainly made up of pump barrel, inlet valve, piston, drain four major part.According to the oil well pump fixed form in down-hole, tubing pump and insert pump can be divided into.Tubing pump is also known as oil-line pump, and feature is urceolus, lining and inlet valve to be assembled on ground be attempted by oil pipe bottom elder generation lower going-into-well, then the piston sucker rod equipped with dump valve is entered in pump by under oil pipe.Lining is become some joints by materials processing, is lining into outer barrel.The hollow circular cylinder that piston seamless steel pipe is made, smooth outer surface is with annular ditch groove, effect is to allow the sand grains entering piston and sleeve clearances be gathered in groove, prevents the oil deposited in sand grains worn piston and lining, and groove from playing the effect of lubrication piston face.Inspection is to release the oil in oil pipe when pumping up pump, can use salvageable inlet valve (standing valve), by transferring roofbolt, allow the buckle of piston bite the fishing head of inlet valve, inlet valve is proposed.But this pump occupies space in pump due to inlet valve fishing head, make the dead space of pump and clearance volume big, easily affected by gas and reduce pump efficiency.Enter the well of tubing pump at present under great majority, be bleeder to be installed, by opening the oil that bleeder is laid down in oil pipe in oil pipe bottom.Enter in the well of big pump under, owing to piston diameter is more than pipe aperture, it is impossible to by entering piston under oil pipe, the method for employing be first piston with in oil pipe lower going-into-well, rear under enter rod string, utilize the device of a referred to as disjointed device to dock with piston in pump.
Current existing oil well pump structure is complicated, and pumping efficiency is relatively low, run time organization less stable.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of simple in construction, and pumping efficiency is high, the oil exploitation oil well pump of good operation stability.
For solving the problems referred to above, the present invention adopts the following technical scheme that a kind of oil exploitation oil well pump, including motor, power transmission shaft, screw rod and body, described motor is located on body, it is provided with seal closure between described motor and body, described power transmission shaft is located at below motor, described power transmission shaft is connected with motor-driven, described screw rod is located in body, described screw rod is fixing with power transmission shaft to be connected, described screw rod end is provided with impeller, described impeller is fixing with screw rod to be connected, corrugated setting inside described body, it is provided with annular seal space between described body and screw rod, described annular seal space is in being equally spaced, described its bottom is provided with drainage screen.
As preferably, described body side is provided with flowline, convenient discharge crude oil.
As preferably, described flowline, in being horizontally disposed with, keeps oil extraction smooth and easy.
As preferably, described flowline being provided with electromagnetic valve, convenient control flowline is fuel-displaced.
As preferably, described motor is servomotor, the convenient rotating speed regulating motor.
The invention have the benefit that the motor of setting can drive screw rod to rotate by power transmission shaft, screw rod rotates and can carry out oil transportation operation with the annular seal space of formation inside body, remain on good stability, the impeller of screw rod end can increase the efficiency of oil transportation, keep oil transportation smooth and easy, drainage screen can effective impurity screening, prevent from causing impeller to damage.
