摘要: 归纳丛式定向井设计中常见障碍物的数学模型有细直圆锥、圆环加斜圆台和空间圆柱三种.分析了绕障设计的必要性,得出在各种障碍物条件下绕障必要性的判断关系式.提出一种新的三维绕障定向井设计方法——斜平面试算法,并给出了设计实例.

Abstract: This paper sammarizes the mathematical models of the obstructions which are often encountered in cluster-directional well drilling designs,It is shown that they can be summarized in to 3 types: thin vertical circular cone,ring,and inclined frustum,and cylinder.It further analyses the necessity of bypassing the obstructions,derives criteria of bypassing under different conditions,and presents a new 3-D design method of bypassing the obstructions-the inclined plane-trial-and-error method.A design example is given also.
