作者对游梁式抽油机优化设计中的设计变量、约束条件和目标函数作了深入分析,指出了若干论述抽油机优化设计文献所存在的问题,认为取抽油机若干特征角度作为设计变量,可使优化维数和约束条件数降至最少。应研究不同井况下的抽油机动力学特性随这些变量变化的规律,以此作为优化设计的基础。 The author makes an in-depth analysis of the design variables, constraints and objective functions in the optimization design of the beam pumping unit, points out some problems existing in the literature about the optimization design of the pumping unit, points out that taking several characteristic angles of the pumping unit as the design Variables minimize the number of optimization dimensions and constraints. The dynamic characteristics of the pumping unit under different well conditions should be studied as a function of the variation of these variables as a basis for optimal design.
