Abstract
Disclosed is an oil pump plunger capable of mixing water. Lower threads of an upper diversion joint are connected with the upper portion of the plunger, the lower portion of the plunger is connected with the middle of a lower diversion joint in a threaded manner, upper threads of the lower diversion joint are connected with the lower portion of a discharging valve, the upper portion of the discharging valve is connected with the lower portion of an inner insertion pipe, the upper portion of the inner insertion pipe is inserted into the upper diversion joint, a water mixing inlet flow channel and an extracted liquid outlet flow channel are arranged inside the upper diversion joint, a water mixing outlet flow channel and an extracted liquid inlet flow channel are arranged inside the lower diversion joint, an annular flow channel is arranged between the plunger and the inner insertion pipe, the water mixing inlet flow channel, the annular flow channel and a water mixing outlet flow channel are communicated with each other, the extracted liquid outlet flow channel is communicated with the upper portion of the discharging valve, and the lower portion of the discharging valve is communicated with the extracting liquid inlet flow channel. A sealing ring is mounted at the position of the upper end of the inner insertion pipe inserted into the upper diversion joint. Hot water or steam are led to flow downwards to the lower side of a pump through the oil pump plunger to heat crude oil on the lower side of the pump without changing the oil discharging mode of the oil pump, and normal production of a heavy oil well can be guaranteed.
Description
Technical field
The utility model is the down-hole pumping unit that petroleum production is used, but particularly a kind of water mixing oil pump plunger piston.
Prior art
In thick oil well is produced, the employing hollow stem water mixing viscosity reduction oil pumping that has.Hollow stem water mixing principle be with hot water or steam from well head enter hollow rod through oil pump plunger piston flow to downwards under the pump with pump under crude oil Hybrid Heating (on pump, not mixing) with crude oil, reach the purpose of viscosity reduction, make the oil well can ordinary production.But existingly through plunger hot water is mixed oil well pump to the pump and will drain into from the pump barrel bottom on the pump in the oil pipe, as Chinese patent application 200920031493.X " mixing streamer water viscosity reduction device ", it is exactly this structure, because it is to begin oil extraction by the pump barrel bottom, and the natural gas of separating in the oil is in pump barrel top, cause natural gas body row not come out, gently then reduce pump efficiency after assembling too much, heavy then cause gas lock, pump can not be pumped, cause oil well to stop production.
Summary of the invention
But the purpose of this utility model provides a kind of water mixing oil pump plunger piston, does not change the oil extraction mode of oil well pump, can be with hot water or steam heating crude oil under oil pump plunger piston is mixed to the pump pump downwards.
The purpose of this utility model has been achieved in that plunger, expulsion valve, also has the tap of going up, interpolation pipe, following tap, last tap lower thread is connected with plunger upper part, the plunger bottom is threaded with following tap middle part, following tap top screw thread is connected with the expulsion valve bottom, expulsion valve top is connected with the interpolation pipe bottom, interpolation pipe top is inserted and is gone up in the tap, there is water mixing to flow into runner in the last tap, extraction liquid flows out runner, there is water mixing to flow out runner in the following tap, extraction liquid flows into runner, between plunger and the interpolation pipe ring runner is arranged, water mixing flows into runner, ring runner, water mixing is flowed out runner and is communicated, extraction liquid flows out runner and communicates with expulsion valve top, and the expulsion valve bottom flows into runner with extraction liquid and communicates.
The interpolation pipe upper end is inserted and is gone up tap place installation seal ring.
The beneficial effects of the utility model: do not change the oil extraction mode of oil well pump, can make hot water or steam heating crude oil under oil pump plunger piston flow under the pump pump downwards, make the thick oil well ordinary production.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a whole-cutaway view.
Embodiment
1 couple of the utility model embodiment describes below in conjunction with accompanying drawing.
As shown in the figure, by last tap 1, plunger 2, interpolation pipe 3, expulsion valve 4, following tap 5, seal ring 6 is formed, last tap 1 lower thread is connected with plunger 2 tops, plunger 2 bottoms are threaded with following tap 5 middle parts, following tap 5 top screw threads are connected with expulsion valve 4 bottoms, expulsion valve 4 tops are connected with interpolation pipe 3 bottoms, interpolation pipe 3 tops are inserted and are gone up in the tap 1, last tap has water mixing to flow into runner 7 for 1 li, extraction liquid flows out runner 8, following tap has water mixing to flow out runner 10 for 5 li, extraction liquid flows into runner 11, between plunger 2 and the interpolation pipe 3 ring runner 9 is arranged, water mixing flows into runner 7, ring runner 9, water mixing is flowed out runner 10 and is communicated, extraction liquid flows out runner 8 and communicates with expulsion valve 4 tops, and expulsion valve 4 bottoms flow into runner 11 with extraction liquid and communicate.Interpolation pipe 3 upper end ends insert to be gone up tap 1 place seal ring 6 is installed, and makes to mix water and can not enter from here in the interpolation pipe 3.
During work, last tap 1 top is connected with hollow rod, following tap 5 bottoms are connected with hollow rod, plunger 2 is in the oil pumping pump barrel, mix hot water or steam and flow into runner 7, ring runner 9, water mixing through hollow rod on the pump, water mixing and flow out under runner 10, the pump hollow rod and flow to pump under and to heating crude oil, crude oil flows into runner 11, expulsion valve 4, interpolation pipe 3, extraction liquid outflow runner 8 through extraction liquid and is flow on the pump by extraction in the well.
