【Abstract】 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.更多还原
