在已知的孔段(设计的或实际的)中,利用楔子(活动楔子或固定楔子)来强制造斜钻具按预期的空间方向钻进,特别是急剧造斜,迄今仍是一项重要手段. 定向造斜的基础,是楔子在孔内的定向理论及其所建立的计算方法.本文就此问题作一探讨. 式算法1.假设与推导设图1中O_1O_2为一下楔孔段(原孔段)的轴线,过点O_1的轴线方位垂直面为P,水平 In known hole segments (designed or actual), the use of wedges (moving wedges or fixed wedges) to force a diagonal driller to drill in the expected spatial direction, particularly sharp slash-hit, is still an important hitherto Means.On the basis of directional slashing, it is the orientation theory of the wedge in the hole and its calculation method.This paper makes a discussion on this problem.Algorithm 1.Hypothesis and derivation Let O_1O_2 in Figure 1 be the wedge hole segment Hole segment) axis, O1 axis over the plane perpendicular to the plane P, horizontal
