摘要
本文用数据拟合、三次样条和数值积分的方法模拟水平井井眼轨迹曲线，为有限元分析提供条件，同时用解三弯矩方程计算水平井中套管初弯曲的内力。通过算例分析说明，本文所述的计算方法可行，而且可靠，对指导钻井工作具有实用意义。
In this Paper, some methods, such as datu fit, cubic spline and data integration.are used to describle the trajectory of horizontal well' That can provide conditions for the finite element analysisymeanwhile, the internal force that will cause of the easing initial buckling is calculated in horizontal wells with themethod of Tri-moment formulate. It has been proven that the method is applicable and reliable throughthe analysis of the case history and will be useful in guiding drilling operation
