Abstract
The utility model provides an efficient protective oil pumping device, and relates to the oil and gas lifting tool technology in oil and gas development. The efficient protective oil pumping device overcomes the defects that in the prior art, a standing valve seat of a tube type oil pump and a standing valve ball of the tube type oil pump are poor in sealing performance and easily damaged, so that washout is caused. A working barrel, a plunger and a standing valve assembly are connected to form the efficient protective oil pumping device, wherein the working barrel is connected with the standing valve assembly in a threaded mode, and the plunger is placed in a cavity of a pump barrel. Third oil and gas passageways are arranged on the upper end face of a standing valve cover, and the standing valve ball is placed in a cavity formed by the standing valve cover and an integration pressing connector. An upper traveling valve is arranged at the inner upper end of the plunger, and a lower traveling valve is arranged at the inner lower end of the plunger. First oil and gas passageways are arranged on the upper edge of the upper traveling valve, and second oil and gas passageways are arranged on the upper edge of the lower traveling valve. The inner portion of the plunger is hollow, and anti-clamping grooves are formed in the outer wall of the plunger. The three or four third oil and gas passageways are evenly distributed on the upper end face of the standing valve cover, the three or four first oil and gas passageways are evenly distributed at the inner upper end of the plunger, and the three or four second oil and gas passageways are evenly distributed on the inner lower end of the plunger.
Description
Technical field: the utility model relates to oil gas lifting implement technology, especially high efficient protected oil rig in natural petroleum gas field.
Background technique: in oilfield development process, the application pumping unit drives the tubing pump mechanical oil recovery and is still the main artificial lifting way in oil field, in recent years, in oil recovery process, because of the pipe type oil pump fixing valve self structure, cause fixed valve base and standing valve joint sealing place to become flexible, under the effect of high-pressure liquid, cause standing valve upper end of joint face thorn to leak and cause pumping well inspection pump always high, not only to machine, adopt management work and brought larger difficulty, and the operating cost that causes thus is high.
Patent No. CN86209054 discloses a kind of Anti-sand oil pump, it is comprised of pump barrel, plunger, standing valve and travelling valve, adopted bitubular annular space sand setting structure, pump barrel has the sand setting urceolus that communicates with oil pipe outward, the sand setting tail pipe is arranged at bottom, sand card in the time of both can having prevented the pump motion, the sand card in the time of can preventing termination of pumping again.This pump can be used for the sand output well of sand factor below 3.6%, and the oil well that does not shake out uses equally.But it does not change traditional standing valve assembly structure, due to the fixed valve ball shock fixed valve base that pumps, causes fixed valve base and pressed joint sealing place loosening, under the effect of high pressure oil, gas, water, causes standing valve upper end of joint face thorn to leak.
Summary of the invention: the purpose of this utility model is to provide fixed valve base and the integrated high efficient protected oil rig of pressed joint, it overcomes the defect of above-mentioned pipe type oil pump fixing valve seat of the prior art, fixed valve ball poor sealing performance, the leakage of fragile thorn, the purpose of this utility model is to realize like this, it is to be formed by connecting by working barrel, plunger, standing valve assembly, working barrel is threaded with the standing valve assembly, and plunger is placed in the cavity of pump barrel.There is the 3rd gas channel the standing valve cover upper-end surface, and fixed valve ball is placed in the cavity of standing valve cover and the formation of integrated pressed joint; In plunger, upper end is equipped with upper travelling valve, and in plunger, lower end is equipped with lower travelling valve; There is the first gas channel the top of upper travelling valve, and there is the second gas channel the top of lower travelling valve.
Plunger inside is hollow, and outer wall is provided with the anti-draw-in groove of annular.
The standing valve cover upper-end surface is evenly equipped with three or four the 3rd gas channels.
The plunger inner upper end is evenly equipped with three or four the first gas channels; The plunger interior lower end is evenly equipped with three or four the second gas channels.
While utilizing the high efficient protected oil rig, integrated pressed joint of the present utility model is threaded with tail pipe, working barrel top is connected with the top oil pipe by screw thread, plunger is threaded with the top sucker rod, when sucker rod drive plunger is up, under the effect of suction force, fixed valve ball is up, and well liquid is provided with gas channel by the standing valve cover upper-end surface and enters working barrel; The effect of head of liquid in oil pipe simultaneously, close upper travelling valve, lower travelling valve, thereby discharge one section liquid of plunger stroke length; When plunger was descending, under the effect of fluid pressure, fixed valve ball was descending in working barrel, with the valve base sealing of integrated pressed joint upper end, in working barrel, liquid backs down upper travelling valve, lower travelling valve, and well liquid in working barrel is entered to the top oil pipe, complete and so forth lifting, realize the oil gas lifting.
The beneficial effects of the utility model are that fixed valve base and pressed joint is integrated, change traditional fixed valve base, fixed valve ball sealing means, solve the pressed joint upper-end surface and easily sting problem leakage, reduce the pumping well operation, avoid the waste of human and material resources, financial resources.
