摘　　要：通过对二维定向井轨迹影响因素 (井轨迹曲线参数 )的分析 ,建立了考虑下部钻具组合特性、轨迹曲线参数、地质要求等因素 ,以最短井轨迹曲线长为目标的二维井轨道非线性规划模型 .根据目标函数及可行域的性质 ,采用均匀设计法选择初始点 ,构建了模型求解算法 .根据算法研制的软件对二维定向井的十余种常见剖面类型均能很快给出最优设计 ,提高了剖面设计的灵活性及计算速度和精度 。Diathesis effecting on trajectory of two-dimensi on directional well will be analyzed copiously in this paper. Characters of infras tructure of drill, parameter of trajectory and geologic request are thought. The ory of nonlinear programming is used to found a model in order to get the minima l path of wells. This paper will discuss the properties of target function and f easible field, and a kind of arithmetic is going to be found by using knowledge of target programming. A method making the point distributed equably is used to choose initialization iterative point, so the time cost is shorter obviously tha n the method of particularization. The software following this paper can find th e best trajectory of ten kinds of usual section designs very quickly. The speed and precision are improving, and the engineering requires are satisfied.
