摘要
建立了三维水平井井眼轨道设计模糊非线性多目标最优控制模型 ,利用模糊集理论把该模型转化为非线性规划问题 ,并把该模型应用到水平井的实际生产中 ,得到满意的结果 .
Multiple objective non-linear optimal control models for designing 3D trajectory in horizontal wells are developed in a fuzzy environment. Model is translated into nonlinear programming by the fuzzy non-linear programming method based on Zimmermann and Lee and Li . Using simulated annealing method solves the nonlinear programming. The model is applied to practical design and satisfactory solution is obtained.
