Abstract
The utility model relates to an oil drain device of an oil pump. The utility model is characterized in that the oil drain device is composed of a main body 1, a pin 2, and a casting rod 3. The utility model is arranged between a pump barrel and a fixed valve in underground. When a well is repaired, after a pump in underground is lifted, the casting rod 3 is cast in, the pin 2 is struck off to cause the inner part of an oil pipe to be communicated with an annular space, and therefore, the purpose of oil drainage can be achieved. The utility model has the advantages of novel and simple structure, convenient operation, and high safety. The utility model can be applied to an oil field.
Description
The utility model relates to a kind of rod-pumped well bleeder that is used for the oil field oil exploitation.
At present, oilfield pumping well on-the-spot with bleeder as Shengli Oil Field HF type bleeder, North China Oilfield KGBX type switching regulator bleeder etc., structure is all complicated, inconvenient operation, safety does not reach requirement, promptly bleeder lost efficacy in the down-hole because of a variety of causes sometimes, caused the well workover accident, produced to the oil field and brought heavy losses.
Task of the present utility model is to provide a kind of new pumping unit well bleeder, adopts this bleeder, and simple in structure, easy to operate, safety can reach 100%, and promptly bleeder can not lose efficacy in the down-hole.
The utility model is to realize like this.It is made up of main body 1, pin 2, caber 3, will finish in the screwed hole of going on the pin 2 in the main body 1 during assembling.
During use, this rod-pumped well bleeder is installed between pump barrel and the standing valve, under the lower going-into-well, when well workover plays pump, after tripping out down-hole pump, drop into caber 3, after caber 3 falls into the down-hole, sever pin 2, make in the oil pipe and annular space UNICOM, promptly reach the draining purpose.
The utility model novelty simple in structure, easy to operate, practical, safe, can widely apply in the oil field.
Accompanying drawing is the utility model structural representation.
Below in conjunction with accompanying drawing enforcement of the present utility model is further described.
Accompanying drawing shows structure diagram of the present utility model.Main body 1 is cylindric, and there is pin thread the upper end, and there is negative thread the lower end, and the internal channel first half has tapering, and is upper coarse and lower fine, in the middle of the main body screwed hole is arranged, and size and pin 2 match; Pin 2 materials are cast steel, and pin thread is arranged at top, and a blind hole is arranged vertically at top, on the cylindrical of pin blind hole bottom a triangular groove are arranged; Caber 3 is the long 4 meters rod irons of a diameter 20cm, and there is tapering the lower end.
