Hydraulic station produces hydraulic oil with high pressure, drive the hydraulic cylinder operation through the hydraulic pipe line, the piston of hydraulic cylinder carries the downhole sucker rod and the plunger to the reciprocating movement, thus to achieve the oil liquid lifting.
1.The operating pressure of the hydraulic cylinder is stable and the system equipment has a long service life.
2.Small size, light quality, easy moved and installed, esp. suitable for shoal, offshore platform and mountainous area pumping operation.
3.Easy to achieve long stroke, low stroke, and stroke, stroke can be steplessly adjusted.
4.It has strong adaptability to large loads and can meet the needs of deep wells and heavy oil wells.
5.Realize remote transmission and automatic control of oil well data.
6.One control more wells, so it achieves to drive more wells on one platform.
The field experiment case
It has been widely used in Shanxi coalbed methane, Xinjiang oilfield, Jilin oilfield and Yanchang oilfield.
