In this paper discrete optimization is applied to a sucker-rod pumping for seeking optimum parameters, such as length of stroke, pumping speed, plunger diameter and pump depth. The authors establish the mathematical models of three objective functions of the initial production rate,inter-grated technical performance and economic return.

In this paper discrete optimization is applied to a sucker-rod pumping for seeking optimum parameters, such as length of stroke, pumping speed, plunger diameter and pump depth. The authors establish the mathematical models of three objective functions of the initial production rate,inter-grated technical performance and economic return. Th? pump depth is taken as a variable. The computer programs are developed to optimize the pumping parameters of sueker-rod pumping well. This program can also be used to tap the potentialities of the oil well and to justify the oil well operation. A case study is given in this paper. |
