Abstract
The utility model relates to a vapor pressure type petroleum extraction pump. After the vapor pressure type petroleum extraction pump is soaked in the underground petroleum reservoir, the pump is fulfilled with petroleum, high pressure gas can enter a pump body (4) through a vent pipe (1) to close a check valve (6) and a check valve (8). A check valve (5) is open, the petroleum can enter a petroleum outlet pipe (3). High pressure gas can enter a pump body (7) through a vent pipe (2) to close the check valve (5) and a check valve (9). A check valve (8) is open, the petroleum can enter a petroleum outlet pipe (3). Meanwhile the vent pipe (1) is stop supplying gases and exhausts gases to open the check valve (6), and then the underground petroleum can enter the pump body (4), thereby the two pumps can work alternately to convey the petroleum in the petroleum outlet pipe onto the ground through the pressure continuously.
Description
Affiliated technical field
The utility model relates to a kind of pneumatic-typed quarrying oil pump device.
Background technique
The current method that a lot of recover petroleums are arranged both at home and abroad, common use rod pump is more, owing to be that unidirectional stroke recovers the oil; So oil production is few, recover the oil with the gaslift method, gas consumption is big especially again; Gas ability utilization ratio is very low, can only just use the airlifting oil recovery method under special circumstances so cost is very high.
Summary of the invention
Problems such as it is few that the utility model purpose is to use pneumatic-typed quarrying oil pump device can solve rod pump one-stroke oil production, and gaslift method oil recovery gas consumption is big, and gas ability utilization ratio is low.
The present invention realizes through following manner, and same oil outlet tube is installed in two pump housings, and two one-way valves are installed on oil outlet tube, at two pump housing upper positions breathing pipe is installed respectively, two pump housing bottoms one-way valve is installed respectively.When pneumatic-typed quarrying oil pump immerses oilbearing stratum; One-way valve is opened by formation pressure and is full of oil in the pump housing, and gas is discharged by breathing pipe in the pump housing, when pressurized gas get into the pump housing by breathing pipe; The one-way valve that the one-way valve of pump housing bottom is closed on the while oil outlet tube by high-pressure gas pressure is opened; Oil in the pump housing is pressed in the oil outlet tube by pressurized gas, supplies with and is opened to pump in this during gas, the oil that oilbearing stratum is interior when stopping pressurized gas; Get into again in the pump housing, like this two pneumatic-typeds quarrying oil phase mutually exchange repeatedly operation make that oil in the oil outlet tube is continual to be gone out ground by force feed.
The utility model is because be two pump housings, and with using an oil outlet tube and two pump housings under the pressure and ground high-pressure gas pressure of oilbearing stratum, oil-feed simultaneously, one are fuel-displaced; Each other exchange is carried out repeatedly, so oil outlet tube is continually to go out ground to the oil force feed, the oil output height; Again because pressurized gas only supply to use in the pump housing gas at every turn; So gas consumption is few, gas ability utilization ratio is high, and cost for oil production is low.
Description of drawings
Accompanying drawing is a pneumatic-typed quarrying oil pump device structural representation.
Fig. 1 is a pneumatic-typed quarrying oil pump body schematic representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment model utility is further specified:
One-way valve [5], [8] are installed above the oil outlet tube [3], and the pump housing [4] is connected with one-way valve [6], breathing pipe [1], outlet pipe [3], the pump housing [7] and one-way valve [9], breathing pipe [2], and outlet pipe [3] is connected.
Pressurized gas get into the pump housing [4] by breathing pipe [1], and one-way valve [8], [6] are closed, and one-way valve [5] is opened; The interior oil of the pump housing [4] gets into oil outlet tube [3]; Pressurized gas get into the pump housing [7] by breathing pipe [2], and one-way valve [9], [5] are closed, and one-way valve [8] is opened; The interior oil of the pump housing [7] gets into oil outlet tube [3], and two pump housings exchange operation each other and make that oil is continual to be gone out ground by force feed.
