Abstract

Abstract:

Constant tool face angle curve is a typical component of well-path in planning, characterized by complex calculation and difficult design solution. The existing models are lack of generality and only have single solving mode, so two typical planning models of well-path with constant tool face angle are proposed to find the flexible and effective solving methods. Aiming at the common design problems of directional wells and horizontal wells, two typical planning models of single and dual constant tool face angle curve(s)combined with line are created to discuss multiple solving methods of design variables. Through rationally setting the initial value of design variable, the quasi-Newton numerical solving method is used to solve the above two types of planning models accurately, rapidly and flexibly. According to calculation examples, these two typical planning models of well-path and their solving methods are correct, reasonable and effective, able to be used for the well-path planning of directional or horizontal well, satisfying various kinds of application requirements.

Key words: directional drilling, well-path, constant tool face angle, planning model, solving method

摘要：

恒工具面角曲线是一种典型的井眼轨道设计模型组件，计算复杂，设计求解难度大。现有模型缺乏一般性，且求解模式单一，为此提出两种典型的恒工具面角井眼轨道设计模型，并寻求灵活、有效的求解方法。针对定向井和水平井一般设计问题，构建了单、双恒工具面角曲线与直线组合两种典型设计模型，探讨了多种设计变量求解方法。通过合理确定设计变量初值，采用拟牛顿数值求解方法，精确、快速、灵活地求解了这两种设计模型。算例应用结果表明，两种典型轨道设计模型及其求解方法合理、有效，可用于定向井和水平井轨道设计。
