Abstract
The utility model relates to a pumping mixed fluid and gas deep well pump, which is formed by improving on the basis of the prior flowing back and oil pumping deep well pump. The utility model has the main improved points that more air change chambers are arranged on the outer wall of a pump barrel, the air change chambers consist of cavities between an air change cover fixed on the outer wall of the pump barrel and the outer wall of the pump barrel, and a seal rubber ring is arranged between the upper end and the lower end on the air change cover, and the contact surface of the wall of the pump barrel. The utility model has the advantages that the pump is especially suitable for the production of the flowing back and the oil recovery of the pumping mixed fluid and gas well in the oil field, the pump efficiency can be enhanced, and the gas locking can be prevented.
Description
Technical field
The utility model relates to a kind of air-liquid mixed pump deep-well pump, is applicable to the discharge opeing of oil field gas-liquid mixed pumping well, the production of recovering the oil.
Background technique
At present, the discharge opeing oil pumping deep-well pump that use in the oil field is made up of pump barrel and plunger, is provided with standing valve in the bottom of pump barrel, is provided with travelling valve in the bottom of plunger, is furnished with through hole at the end face of plunger.Its shortcoming is owing to contain gas in various degree in the well, influences pump efficiency, even causes gas lock, can not ordinary production.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, can improve pump efficiency, prevent the air-liquid mixed pump deep-well pump of gas lock.
The technological scheme that its technical problem that solves the utility model adopts is: it includes pump barrel, plunger, bottom at pump barrel is provided with standing valve, bottom at plunger is provided with travelling valve, end face at plunger is furnished with through hole, it is characterized in that on the outer wall of pump barrel, being provided with more than one air-exchanging chamber, air-exchanging chamber constitutes by being fixed on range hood on the pump barrel outer wall and the chamber between the pump barrel outer wall, be distributed with air-vent on the pump barrel wall in air-exchanging chamber, air-vent is in the total height of the pump barrel axial direction length less than plunger, between the surface of contact of two ends and pump barrel wall O-ring seal is housed up and down at range hood.
Air-vent is any in the following form: uniform vertical slotted eye, uniform horizontal slotted eye, spiral slotted eye, uniform circular hole, uniform elliptical aperture.
Air-exchanging chamber is positioned at the upper, middle and lower of pump barrel.
The beneficial effects of the utility model are the discharge opeing that is specially adapted to oil field gas-liquid mixed pumping well, the production of recovering the oil, and can improve pump efficiency, prevent gas lock.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of air-exchanging chamber of the present utility model.
Embodiment
By Fig. 1, embodiment shown in 2 as can be known, it includes pump barrel 1, plunger 3, be provided with standing valve 8 in the bottom of pump barrel 1, be provided with travelling valve 7 in the bottom of plunger 3, end face at plunger 3 is furnished with through hole 2, particularly on the outer wall of pump barrel 1, be provided with more than one air-exchanging chamber 5, air-exchanging chamber 5 constitutes by being fixed on range hood 6 on pump barrel 1 outer wall and the chamber between the pump barrel outer wall, be distributed with air-vent on the pump barrel wall in air-exchanging chamber 5, air-vent is in the total height of the pump barrel axial direction length less than plunger 3, between the surface of contact of range hood two ends and pump barrel wall about in the of 6 O-ring seal 10 is housed.
The air-vent of present embodiment is uniform vertical slotted eye 4, also can adopt uniform horizontal slotted eye, spiral slotted eye, uniform circular hole, uniform elliptical aperture etc.
All can in the upper, middle and lower that air-exchanging chamber is positioned at pump barrel.
In Fig. 2,9 is rivet.
Working procedure of the present utility model is as follows:
In the gas-liquid mixed pumping well, during plunger 3 down strokes, pressurized gas enters air-exchanging chamber 5, and when below plunger 3 walks to range hood 6, the gas in the plunger 3 top air-exchanging chambers is displaced outside the well by well liquid, realizes the deep-well pump gas production.Plunger 3 up strokes are during to upper dead center, and liquid fall in the last air-exchanging chamber 5 of plunger 3 belows, and enough well liquid is arranged all the time at standing valve 8 tops, and plunger 3 standing valve 8 when lower dead centre is up can in time be opened, and can not cause gas lock.
