The Research And Application Of The Method Of The Optimization Of Artificial Lift Patterns Of Pumping Jack And Screw Pump

At present, the artificial lift patterns used in Daqing Oilfield mainly include: pumping jack and screw pump. For a reservoir (block and oil well) choosing the right way of artificial lift patterns concerning about whether it can be reasonable, high efficiency, energy-saving oil-recovery. Therefore, the study of the method of the optimization of artificial lift patterns of pumping jack and screw pump has practical engineering significance.for high and stable production in Daqing oilfield.In the basis of analysising the state of the process and the adaptability of pumping jack and screw pump, the mathematical models of fuzzy evaluation which was the objective function matrix of the optimization of of artificial lift patterns and can be available to the optimization of the artificial lift patterns of pumping jack and screw pump were established, and the method of the optimization of artificial lift patterns by caculating the objective function array was given in this paper. A software on the optimization of artifical lift patterns of pumping jack and screw pump in Daqing Oilfield was programmed using VB6.0, and it was applied to 7 wells, such as X8-D4-130 of Daqing Oil Recovery Plant No. 5, the optimized results show that the artificial lift patterns optimized using the optimization method given in this paper are in accord with those chosen through practical experiences of 6 wells, such as X8-D4-130.
