摘要/Abstract

摘要： 为让圆弧型井眼轨道设计模型的求解方法简洁、有效、快速且具有足够精度，提出了井眼轨道解析、扫描和迭代的综合求解法。讨论了三段制和五段制两种典型的圆弧型井眼轨道及其初值问题。对于三段制轨道，利用其几何性质直接给出解析计算公式；对于五段制轨道，分为约束目标井段的井斜角或方位角、约束中间稳斜段的井斜角或方位角两大类，并建立了简洁的参数约束方程，提出了先以图谱扫描初步求解、再以此为初值迭代求解的综合求解方法。研究结果表明，所提出的算法简单实用，易于编程实现，在三维定向井和水平井设计中具有应用价值。

Abstract: To obtain the concise, effective, fast and sufficiently-precise solving method for the design model of arc-type well-path, this paper proposes a comprehensive solving method involving the analysis, scanning and iteration, and explores two typical arc-type well-path, i.e., three-section path and five-section path, as well as their initial value problems. For the three-section path, an analytical calculation formula is directly given using its geometric properties; for the five-section path, two types of constraint conditions are distinguished according to the inclination angle or azimuth angle for both target and middle holding section, respectively. Moreover, this paper has established a simple constraint equation for model parameters, and puts forward a comprehensive solving method that solves the problem by scanning the spectrum, using this result as the initial value for iterative solution afterward. The research results show that the proposed algorithm is simple and practical, easy to implement by programming, and has application value in the design of three-dimensional directional wells and horizontal wells.
