Abstract
An efficiency-improving sand prevention device of an oil well pump comprises an adapter connector, a valve seat, a mechanical valve and a plunger piston, wherein the mechanical valve penetrates the valve seat from bottom to top, a valve cone at the lower portion of the mechanical valve is in matched sealing with a valve opening at the lower portion of the valve seat, and the lower portion of the adapter connector is connected with the upper portion of the mechanical valve. When the mechanical valve and the valve seat are in a closed state, a distance between the lower end face of the adapter connector and the upper end face of the valve seat is 5-20mm, the lower portion of the valve seat is connected with the upper portion of the plunger piston, and a valve on the plunger piston is arranged at the upper portion of the plunger piston, so that the length of the mechanical valve is small, the mechanical valve can be processed integrally, and the problems existing in the prior art are overcome. The service life of the mechanical valve can be prolonged, accordingly the service life of the oil well pump is prolonged, sands do not deposit in the plunger piston, an oil flowing channel is not blocked, an oil well production period can be prolonged, and the economic benefit can be improved.
Description
Technical field
The invention belongs to the equipment that oil pumping in oil fields is used, particularly a kind of oil well pump synergy sand control device.
Background technique
As shown in Figure 1, the valve cone 05 of mechanical valve type oil pump plunger piston can open and close with the sucker rod that is connected on valve rod 02, as long as the ground sucker rod drives the sucker rod to-and-fro motion, valve cone 05 just can open and close, be adapted at using in the high oil well of thick oil well and air content, can increase pump efficiency.But the valve rod 02 on existing mechanical valve type oil pump plunger piston will pass plunger 03, the length of plunger 03 is generally 1.2m, so the length of valve rod 02 must be greater than 1.2m, valve seat 04, valve cone 05 are that special material could be used as valve member through strengthening heat treatment, therefore, valve rod 02 must be formed by connecting for two bodies with valve cone 05.Thereby present mechanical valve type oil pump plunger piston structure is, valve rod 02 with pass plunger 03 after valve cone 05 is connected, valve rod 02 top is connected with variable buckle joint 01, is connected to the valve cone 05 and valve seat 04 fitted seal that is connected to plunger 03 bottom of valve rod 02 bottom.Easily thread off after the alternations that connecting thread process between this structure valve rod 02 and valve seat 04 is hundreds thousand of times, annular space between valve rod 02 and plunger 03 is long, easily sand setting stops up oil flow channel, a lot of problems in use appearred, affect the oil well production cycle, reduced the economic benefit of oil well.
Summary of the invention
The objective of the invention is to design a kind of oil well pump synergy sand control device, improve the working life of oil well pump, extend the oil well production cycle, improve the economic benefit of oil well, prevent that sand from stopping up oil flow channel.
The object of the present invention is achieved like this: comprise variable buckle joint, valve seat, mechanical valve, plunger, mechanical valve is passed valve seat from bottom to top, the valve port fitted seal of the valve cone of mechanical valve bottom and valve seat bottom, the bottom of variable buckle joint is connected with the top of mechanical valve, when mechanical valve and valve seat are in closed condition, distance between the lower end surface of variable buckle joint and the upper-end surface of valve seat is 5-20mm, and the bottom of valve seat is connected with the top of plunger, and UNICOM's groove is arranged on valve seat.
The invention has the beneficial effects as follows: the valve element design on plunger is on the top of plunger, thereby the length of mechanical valve is short, integrative-structure be can be processed into, thereby the problem that prior art exists, the working life that can improve mechanical valve overcome, thereby improve the working life of oil well pump, can not deposit sand in plunger, oil flow channel can be not blocked, can extend the oil well production cycle, increase economic efficiency, reach the purpose of synergy sand control.
Description of drawings
Accompanying drawing 1 is the erection drawing of existing machinery valve formula oil pump plunger piston.
Accompanying drawing 2 is erection drawings of the embodiment of the present invention.
Embodiment
Describe below in conjunction with 2 pairs of embodiments of the invention of accompanying drawing.
embodiments of the invention comprise variable buckle joint 1, valve seat 3, mechanical valve 4, plunger 5, mechanical valve 4 is passed valve seat 3 from bottom to top, the valve port fitted seal of the valve cone of mechanical valve 4 bottoms and valve seat 3 bottoms, the bottom of variable buckle joint 1 is connected with the top of mechanical valve 4, screw thread is arranged at the top of variable buckle joint 1, be generally the sucker rod screw thread, in order to be connected with the sucker rod on top, for little pump, to be connected a pull bar between variable buckle joint 1 and sucker rod, when mechanical valve 4 and valve seat 3 are in closed condition, distance between the upper-end surface of the lower end surface of variable buckle joint 1 and valve seat 3 is 5-20mm, the impact when restriction of adjusting the distance can reduce the sucker rod commutation, reduce and thread off and fracture, the bottom of valve seat 3 is connected with the top of plunger 5, this joint will guarantee sealing.UNICOM's groove 2 is arranged on valve seat 3, and UNICOM's groove 2 can oil extraction when descending.
Be connected to sucker rod on variable buckle joint 1 during work when up, mechanical valve 4 contacts with valve seat 3, realizes closing, and when sucker rod is descending, mechanical valve 4 is separated with valve seat 3, realizes opening oil extraction.
The bottom of plunger 5 can connect other parts easy to use.
