Abstract
An oil well pump pumping-assisting production-increase device is mainly composed of a rotational flow pumping-assisting pipe, an oil pipe hoop and a sieve pipe. The oil well pump pumping-assisting production-increase device is characterized in that the rotational flow pumping-assisting pipe is connected with an inlet of a rod oil well pump, the sieve pipe is connected with the lower end of the rotational flow pumping-assisting pipe, and the lower end of the sieve pipe is connected with a tail pipe; and the center of the rotational flow pumping-assisting pipe is designed to be two rotational flow sections, and two small ports of the two rotational flow sections are opposite to each other. The two small ports of the two rotational flow sections are opposite to each other, an invariant-diameter throat pipe is installed between the two rotational flow sections, the upper rotational flow section is long, the lower rotational flow section is short, and a plurality of holes which are inclined upwards towards the centerline are formed on the periphery of the sieve pipe. The oil well pump pumping-assisting production-increase device effectively solves the problems that mixed liquor entering into the oil well pump is not stable and feed flow capability is poor, improves the coefficient of admission and the pump efficiency of the oil well pump, and has obvious effects especially for oil wells which are lower than reasonable submergence depths.
Description
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.
Background technique
The oil field at home major part all is to mid-late oilfield development at present, and main oil production method is mechanical oil recovery, and major part is 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 unstable state of rod pumping pump, particularly stratum energy is not enough, the pump submergence is less than the well of reasonable submergence, and unstable state is more obvious, makes oil well pump import feed flow not enough, 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.
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 is achieved in the following ways:
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 inlet 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, lower eddy flow section is short, screen casing week side be provided with upward several holes in center line.
It is unstable that the utility model has solved the mixed solution that advances oil well pump effectively, and the problem that fluid supply capacity is poor has improved filling index and the pump efficiency of oil well pump, and especially to being lower than the oil well of reasonable submergence, effect is more obvious.
Description of drawings
Accompanying drawing is structural representation of the present utility model
1-eddy flow helps and takes out pipe among the figure, 2-tubing coupling, 3-screen casing.
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 mainly by eddy flow help take out pipe 1, tubing coupling 2 and screen casing 3 form, and it is characterized in that eddy flow helps to take out the inlet that pipe 1 is connected in rod pumping pump, screen casing 3 is connected in eddy flow and helps and take out pipe 1 lower end, screen casing 3 lower ends are 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, lower 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 part of oil casing annular space, when oil pumping, profit in the tail pipe and the oil of oil casing annular space enter simultaneously eddy flow and help and take out pipe, improved gradually the flow velocity of oil water mixture through lower eddy flow section, reduce gradually again the flow velocity of profit to the forward spin flow section, be in steady state when making it advance pump.Disturb without gas, improved filling index and the pump efficiency of oil well pump, increase crude output.
