| 摘 要： | 在定向井轨道设计、实钻轨迹监控等一系列问题中,圆弧井段参数计算是一个最基础的问题。前人提出的圆弧井段井斜角和方位角的计算公式具有计算复杂、推导过程烦琐等缺点,为此以坐标增量恒等式为基础,使用初等方法推导出了一组新的圆弧井段井斜角和方位角的计算公式。这组新公式具有简洁对称、结构清晰等特点。基于井眼曲率是空间圆弧井段的不变量,还给出了井底参数预测的一种新方法。 |
| 关 键 词： | 定向井 空间圆弧 井斜角 方位角 井眼轨迹 井底参数预测 |

| Abstract: | Circular arc well section parameter calculation is the most primary question among a series of questions of directional orbit design and actual surveyed trajectory. Due to the complicated calculation formula and trivial deduction course proposed by predecessor, this article derivated a new calculation formula for circular arc well section deviation angle and positional angle based on increment of coordinate identical equation. This series of new formula has advantages of concise symmetry and clear structure. This article also provided a new method of predicting well bottom parameter according to well bore hole curvature, which is invariable of space well circular arc section. |
| Keywords: | directional well space circular arc orbit deviation angle position angle bore hole well track well bottom parameter prediction |
