Abstract
An oil extraction pump assistant pumping increase production equipment comprises a swirl assistant pumping tube, a oil tube connecting hoop and a griddle tube, which is characterized in that the swirl assistant pumping tube is connected with the input of an oil extraction pump with rod, the griddle tube is connected with the lower end of the swirl assistant pumping tube, the lower end of the griddle tube is connected with a tail tube; the center of the swirl assistant pumping tube is provided with two opposite ventage swirl sections, the middle of the swirl sections is provided with a throat tube without changing diameter, the upper swirl section is longer, and the lower swirl section is shorter, the circumference of the griddle tube is provided with a plurality of holes upward and inclined to the center line. The utility model effectively solves the problems of instable mixed liquid input to the oil extraction pump and the bad supply liquid ability, which improves full coefficient and pump efficiency of oil extraction pump, in particular to an oil well less than reasonable sinking degree, the effect becomes more apparent.
Description
One, technical field
The utility model relates to oil field used a kind of oil well pump in mechanical oil recovery to be helped and takes out increasing device.
Two, background technology
Present domestic oil field major part all is to the oil field development middle and later periods, and main oil production method is a mechanical oil recovery, and major part is a sucker rod pumping in mechanical oil recovery.The import tail pipe section of rod pumping pump is the low-pressure area of oil gas aqueous mixtures reciprocation cycle, caused the import feed flow labile state of rod pumping pump, stratum energy deficiency particularly, the pump submergence is less than the well of reasonable submergence, and labile state is more obvious, makes oil well pump import feed flow deficiency, especially arrived the gas slug, the oil well pump standing valve is not all opened, and causes the pump sky to take out, and oil well pump is worked under inefficient state for a long time.
Three, summary of the invention
The purpose of this utility model provides a kind of oil well pump and helps and take out increasing device, solves the problem that above-mentioned prior art exists.
The technical solution of the utility model realizes in the following manner:
The utility model is helped by eddy flow and takes out pipe, tubing coupling and screen casing and form, and it is characterized in that eddy flow helps to take out the import department that pipe is connected in rod pumping pump, and screen casing is connected in eddy flow and helps and take out the pipe lower end, and the screen casing lower end is connected in tail pipe; Eddy flow helps to be taken out tube hub and is made as two relative eddy flow sections of osculum, and osculum is relative, and the centre is made as one section not reducing trunnion, the forward spin flow segment length, following eddy flow section is short, screen casing week side be provided with upward several holes in center line.
The utility model has solved the mixed liquor instability of advancing oil well pump effectively, and the problem of fluid supply capacity difference has improved the coefficient of fullness and the pump efficiency of oil well pump, and especially to being lower than the oil well of reasonable submergence, effect is more obvious.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
The 1-eddy flow helps and takes out pipe 2-tubing coupling 3-screen casing among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
As shown in the figure, the utility model by eddy flow help take out pipe 1, tubing coupling 2 and screen casing 3 are formed, it is characterized in that eddy flow helps to take out the import department that pipe is connected in rod pumping pump, screen casing is connected in eddy flow and helps to take out and manage the lower end, the screen casing lower end is connected in tail pipe; Eddy flow helps to be taken out tube hub and is made as two relative eddy flow sections of osculum, and osculum is relative, and the centre is made as one section not reducing trunnion, the forward spin flow segment length, following eddy flow section is short, screen casing week side be provided with upward several holes in center line.Oil well pump is in the process of taking out, mixture of oil, water and gas in the oil reservoir flows into behind the shaft bottom under the effect of strata pressure, being raised to screen casing and eddy flow in the tail pipe helps and takes out pipe, oil well pump is not when pumping, gas in the tail pipe enters the topmost of oil casing annular space, when oil pumping, the profit in the tail pipe and the oil of oil casing annular space enter eddy flow simultaneously and help and take out pipe, the eddy flow section has improved the flow velocity of oil water mixture gradually under the warp, reduce the flow velocity of profit again gradually to the forward spin flow section, be in stable state when making it advance pump.No gas disturbs, and has improved the coefficient of fullness and the pump efficiency of oil well pump, increases crude output.
