Abstract
The utility model discloses an eccentric oil inlet respective-pumping and mixed-outtake oil pump. An upper discharging valve is mounted on an upper plunger; the upper plunger is located in an upper pump cylinder, and is sealed with the upper pump cylinder in a matched manner; a lower oil discharging valve is mounted on a lower plunger; the lower plunger is located in a lower pump cylinder, and is sealed with the lower pump cylinder in a matched manner; a lower pump oil inlet valve is mounted at the lower part of the lower pump cylinder; an upper pump oil inlet valve is mounted between the upper pump cylinder and the lower pump cylinder; the upper part of a connecting rod is connected with a communication connector; the upper part of the communication connector is connected with the upper discharging valve; the lower part of the connecting rod is connected with the lower plunger; an eccentric valve set is mounted on the upper pump oil inlet valve; the upper pump oil inlet valve is mounted between the upper pump cylinder and the lower pump cylinder, as a result, no clearance is reserved in an upper pump, the effect on the pump efficiency from gases can be eliminated, the pump efficiency of the oil pump can be greatly improved, and gas locking can not occur; the valve set on the upper pump oil inlet valve adopts an eccentric structure and is mounted on one side, so that the diameter of a valve ball can be increased, the flexibility of a valve ball switch is improved, the reliability of the oil pump is enhanced, and the service life of the oil pump is prolonged.
Description
Technical field:
The utility model is the down-hole pumping unit that oil extraction in oil field is used, and is that a kind of eccentric oil-feed divides to take out and mixes out oil well pump.
Background technique:
Most wells has been penetrated out a plurality of oil reservoirs at present, pressure due to each oil reservoir, moisture difference, close while adopting and interfere with each other, high pressure zone compacting low pressure layer, make low pressure layer not bring into play effect, even can there is the problem that high pressure zone pours in down a chimney to low pressure layer, cause oil well water breakthrough, have a strong impact on oil well production, in order to address this problem, the normal way that adopts separate zone production, but existing eccentric oil-feed divides, take out the upper oil pump inlet valve that mixes out oil well pump and be arranged between two pump barrels, owing to being subject to the restriction of casing inner diameter, upper oil pump inlet valve valve ball diameter is less, during oil pumping, be easy to work ineffective, cause that oil well is not fuel-displaced.Chinese patent application 201120179736.1 < < divide to take out and mix out oil well pump > >, upper oiling valve bulb diameter is not limited by or not pump footpath, can increase oiling valve bulb diameter, but between its connecting tube and lower pump barrel, be clearance, make the clearance of pump on it very large, cause the pump efficiency of oil well pump low, gas lock even can occur not fuel-displaced, oil well deficiency in economic performance.
Summary of the invention:
The purpose of this utility model is that a kind of eccentric oil-feed of design divides to take out and mixes out oil well pump, makes the valve ball diameter of oil pump inlet valve it on large, the clearance of pump oil suction chamber in minimizings, the impact of minimizing gas on pump efficiency, the pump efficiency of raising oil well pump.
The purpose of this utility model is achieved in that and comprises pump barrel, upper plug, upper expulsion valve, UNICOM's joint, upper oil pump inlet valve, connecting rod, lower pump barrel, lower plunger, lower draining valve, lower oil pump inlet valve, on upper plug, install expulsion valve, upper plug is in upper pump barrel, upper plug and upper pump barrel fitted seal, lower draining valve is installed on lower plunger, lower plunger is in lower pump barrel, lower plunger and lower pump barrel fitted seal, lower oil pump inlet valve is installed in the bottom of lower pump barrel, between upper pump barrel and lower pump barrel, install oil pump inlet valve, the top of connecting rod is connected with UNICOM joint, the top of UNICOM's joint is connected with upper expulsion valve, the bottom of connecting rod is connected with lower plunger, a set of eccentric valve group is installed on upper oil pump inlet valve.
The beneficial effects of the utility model are: between upper pump barrel and lower pump barrel, install oil pump inlet valve, make pump there is no clearance, can eliminate the impact of gas on pump efficiency, can greatly improve the pump efficiency of oil well pump, gas lock can't occur, and the valve group in upper oil pump inlet valve is eccentric structure, and valve group is arranged on a side, can increase valve ball diameter, improve the flexibility of valve ball switch, increased the reliability of oil well pump, can extend the working life of oil well pump, therefore, the utlity model has significant economic benefit.
Accompanying drawing explanation:
Accompanying drawing is the utility model embodiment's erection drawing.
Embodiment:
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.As seen from the figure, embodiment of the present utility model comprises pump barrel 1, upper plug 2, upper expulsion valve 3, UNICOM's joint 4, upper oil pump inlet valve 5, connecting rod 6, lower pump barrel 7, lower plunger 8, lower draining valve 9, lower oil pump inlet valve 10, on upper plug 2, install expulsion valve 3, upper plug 2 is in upper pump barrel 1, upper plug 2 and upper pump barrel 1 fitted seal, lower draining valve 9 is installed on lower plunger 8, lower plunger 8 is in lower pump barrel 7, lower plunger 8 and lower pump barrel 7 fitted seal, lower oil pump inlet valve 10 is installed in the bottom of lower pump barrel 7, between upper pump barrel 1 and lower pump barrel 7, install oil pump inlet valve 5, the top of connecting rod 6 is connected with UNICOM joint 4, the top of UNICOM's joint 4 is connected with upper expulsion valve 3, the bottom of connecting rod 6 is connected with lower plunger 8, a set of eccentric valve group is installed on upper oil pump inlet valve 5.General two outlet valves of installing on upper plug 2, lower plunger 8.On UNICOM's joint 4, there is linked hole.
While going into the well, after upper pump barrel 1, upper oil pump inlet valve 5, lower pump barrel 7, lower oil pump inlet valve 10 link into an integrated entity with the design attitude that under oil pump tubular column to oil well is, upper plug 2, upper expulsion valve 3, UNICOM's joint 4, connecting rod 6, lower plunger 8 link into an integrated entity and are lowered in pump with sucker rod, make it in state shown in the drawings.
During oil pumping, two of the bottoms of the bottom of upper plug 2, lower pump barrel 7 oil suction chamber enters oil extraction simultaneously to be realized two oil reservoirs and pumps simultaneously.After the fluid that during oil extraction, two pumps are discharged mixes on pump, be discharged to ground, therefore be referred to as minute to take out, mix out.
