The design technology of rod pump well with no tubing raising system;

Nodal analysis method and application of rod pump production in polymer flooding;

To solve the problems of rod pump such as stroke loss and lower pump efficiency caused by fluid production force deficiency in the formation of the low permeability but high oil saturation, the layering oil production technology rod jet pump is developed.

Designing the submergence depth of sucker rod pump with curve fitting;

Analysis on common subsurface failure of the sucker rod pumping installation;

With the development of the oilfield, deviated wells, sidetracking wells and horizontal wells have more and more important function,whereas the particularity of casing programme limited the landing depth of sucker rod pump,and affected the producibility of oil well seriously.

Optimization of sucker rod pumping system' efficiency for lower permeability reservoir directional well;

Comprehensive control of eccentric wear of sucker rod and tubing in rod pumped wells in Shuanghe Oilfield;
