Abstract
The utility model relates to a special plunger pump for an oil well, which is composed of an air cylinder body, a plunger and a connecting rod. The special plunger pump is characterized in that the air cylinder body is fixedly connected with a base of an oil extractor, the upper part of the plunger is connected with a walking beam of the oil extractor through the connecting rod, an air inlet pipeline at one end of the air cylinder body is connected with a sleeve pipe, and an air inlet valve is connected to the air inlet pipeline; an air outlet pipeline at the other end of the air cylinder body is connected with an oil outlet pipeline, and an exhaust valve, a gate valve and a check valve are connected to the air outlet pipeline. The special plunger pump is an auxiliary device for intensifying oil extraction, is utilized by being matched with the oil extractor and increases the oil well output through reducing the sleeve pipe pressure largely.
Description
Technical field:
The utility model relates to the special-purpose plunger pump of a kind of oil well, is a kind of auxiliary device of intensified oil reduction.
Background technique:
In the oil recovery process of oil field, pumping unit can make the interior a large amount of rock gas of oil well accumulate on the oil level of oil well casing in coming and going oil pumping process, and the gas that accumulates produces negative pressure to oil level, has reduced the oil pumping effect of pumping unit.Usually can adopt the well head outlet valve of manually opening oil well; rock gas is discharged in the air; this not only causes a large amount of rock gas wastes; and to around environment produce to pollute, increased working strength of workers, especially if forget the gas of discharging oil well casing for some reason; gas accumulation is too much in the oil well casing; reduce the oil pumping effect, even cause burn-down of electric motor, production accidents such as oil well stopping production.
Summary of the invention:
The purpose of this utility model is to provide a kind of oil well special-purpose plunger pump, is a kind of auxiliary device of intensified oil reduction, with the supporting use of pumping unit, by reducing casing pressure significantly, improves oil well output.
The technical solution of the utility model is achieved in that the special-purpose plunger pump of oil well, form by cylinder block, plunger, connecting rod, it is characterized in that: cylinder block is fixedlyed connected with oil pumping unit base, plunger upper part links to each other with the walking beam of pumping unit by connecting rod, the air inlet pipeline of one end of cylinder block links to each other with sleeve pipe, is connected with on the air inlet pipeline and brings air valve into; The gas exhaust piping of the other end is connected with flow line, is connected with outlet valve, gate valve, one-way valve on the gas exhaust piping.
Good effect of the present utility model is a kind of auxiliary device of intensified oil reduction, with the supporting use of pumping unit, by reducing casing pressure significantly, reduce the back pressure of sleeve pipe gas to oil reservoir, and then produce bigger producing pressure differential, and improve the oil well pump filling index, improve oil well output.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the special-purpose plunger pump of oil well, form by cylinder block 3, plunger 2, connecting rod 1, it is characterized in that: cylinder block 3 is fixedlyed connected with oil pumping unit base, plunger 2 tops link to each other with the walking beam of pumping unit by connecting rod 1, the air inlet pipeline of one end of cylinder block 3 links to each other with sleeve pipe, is connected with on the air inlet pipeline to bring air valve 4 into; The gas exhaust piping of the other end is connected with flow line, is connected with outlet valve 5, gate valve 6, one-way valve 7 on the gas exhaust piping.
When pumping unit is up, it is up that the connecting rod 1 that links to each other with the walking beam of pumping unit drives plunger 2, the suction valve 5 of cylinder block 3 one ends is opened, in-cylinder pressure descends, after gas is inhaled in the sleeve pipe 8 sleeve pipe 8 internal pressures will be descended, and reduce the negative pressure of sleeve pipe 8 interior gases, and then produced bigger producing pressure differential oil reservoir, improved the filling index of oil well pump, gas enters cylinder block 3 inner chambers in the sleeve pipe 8.When pumping unit was descending, plunger 2 pressurized gass entered flow line by the outlet valve on the gas exhaust piping of cylinder block 3 the other ends 5, gate valve 6, one-way valve 7, finished once operation.
