摘　　要：在邻井井段曲线类型为圆柱螺线时,通过数学变换,将邻井间最近距离点的约束方程转化为一个形式更简单的约束方程;使用二分法,得到了一个计算量最小且收敛性好的新的迭代算法。新算法可应用于钻井轨道设计、井眼轨迹监控等实际问题中。When the interval curve type of adjacent well is cylinder helical,the constraint equation of the near distance spot of adjacent well is simplified further by mathematical manipulation.A new iteration algorithm is obtained by using dichotomy,with little calculated amount and good convergence.The new algorithm can be used to solve field problem,such as well drilling track design and well course monitor.
