Abstract
The utility model relates to a plunger type air extracting pump for an oil well, belonging to an air pump class. The plunger type air extracting pump for an oil well is composed of a cavity plunger, a cylinder body with an air inlet valve and an air outlet valve, and a sealing device. The air inlet valve of the plunger type air extracting pump for an oil well is connected with an oil well, and the air outlet valve is mutually connected with a natural gas station. The oil gas in the oil well is extracted through the work of the plunger type air extracting pump for an oil well. The oil well forms negative pressure, an oil surface is raised, the yield of the oil well can be enhanced, and the oil well which can not discharge oil can be caused to continuously produce oil.
Description
The utility model belongs to the air pump class.
In the exploitation in oil field, because oil constantly is sucked out from underground, subsurface pressure is more and more littler, causes pasta constantly to descend, and the suction subterranean oil is more and more difficult, and oil well output is constantly descended, have in addition to become dried-up well no longer fuel-displaced.
The purpose of this utility model is: a kind of oil well plunger type extraction pump that makes oil well produce negative pressure, raising well recovery amount is provided.
Technical measures of the present utility model are: adopt a plunger by cavity, have the plunger type extraction pump that the cylinder body of suction valve and gas outlet valve is formed; The suction valve of extraction pump is connected with well head, and steam outlet pipe is connected with the rock gas station.
Extraction pump of the present utility model has the good effect that makes oil well improve output.
Fig. 1 is an application schematic representation of the present utility model.
Fig. 2 is the structural representation of a kind of plunger type extraction pump of the present utility model.
Drawing explanation and embodiment are described below: 1 is the walking beam, the 2nd of beam pumping unit among the figure, connecting rod, the 3rd, and the plunger of cavity, the 4th has the cylinder body of suction valve 5 and gas outlet valve 6.Suction valve 5 is connected with oil well 7, and gas outlet valve 6 is connected with natural gas station 8.The reciprocally swinging of walking beam 1 moves back and forth up and down plunger 3 by connecting rod 2, suction valve 5 and gas outlet valve 6 replace leaves valve, oil gas in the oil well 7 is extracted in the natural gas station 8, make and produce negative pressure in the oil well, underground pasta rises, subterranean oil is extracted out ground by pumping unit, makes oil well improve output, even makes the dead oil well continuous produce oil of seam of waking up from death.Above-mentioned extraction pump can be by the plunger 3 of cavity, has that the cylinder body 4 of suction valve 5 and gas outlet valve 6 forms, and in order to prevent gas leakage, on plunger 3 the choke ring can be housed, and seal ring apparatus can also be housed in cylinder body.Suction valve 5 and gas outlet valve 6 can be processed into one with cylinder body, and for the volume that makes extraction pump is little, suction valve 5 and gas outlet valve 6 can be processed into monomeric form, are connected on the cylinder body with the clip structure.Extraction pump of the present utility model can adopt the structural type of Fig. 2, and seal arrangement 15 of the cylinder body 4 that this extraction pump is made up of plunger 3, cylinder barrel 12 and the cylinder seat 16 of cavity, the guide pin bushing 13 in the cylinder body 4, guide pin bushing 13 lower ends, the pump nozzle on the cylinder body 4 14 and the suction valve of being made up of valve body 19, valve seat 20, valve rod 21 and spring, stem guiding frame 22 5 and gas outlet valve 6 are formed.Suction valve 5 is connected with cylinder body by clip 18 with gas outlet valve 6.There is pin connecting plate 9 to be connected with the walking beam 1 of pumping unit in plunger upper end seam through pump rod; Bottom surface seam at the cylinder seat 16 of cylinder body 5 has pin connecting plate 23 to be connected with the oil pumping frame.10 and 17 is nuts among the figure, and its effect is that cylinder barrel 12 and cylinder seat 16 are connected as one formation cylinder body 4.11 is adjustment sleeves among the figure.
