Optimization of suction parameter of pumping well in low permeability reservoir from grey analytic hierarchy process;

By using the improved suction parameters containing polished rod stroke, pump plunger diameter and pump depth changed, the mathematical models of simulating system efficiency were developed according to .

Efficiency analysis of sucker-rod pumping system and optimal design of swabbing parameter;

A method for systematical engineering analysis is used to describe the procedures for its1parameter design, and the method for optimum design of swabbing parameters is established for rod pumpi.

To achieve the purpose of raising the system efficiency of mechanical recovery in pumping wells and saving electrical energy, efforts should be made to strengthen the work of routine management, technical management, and optimization discussion of swabbing parameters.

A method of optimization of pumping well production system was studied, and the swabbing parameters of some pumping wells of Liaohe oil field are optimized,results show that the optimum combination of swabbing parameters of pumping well can be realized by using this method.
