水平井选料轨迹有一般造斜、垂直造斜点、目的层水平段、稳斜加下造斜、上选料加稳斜、单一稳斜、双圆弧造斜、单圆弧造斜及单圆弧造斜加水平稳斜轨迹等9种类型。本文推导了这9种水平井造科轨迹的设计公式，对9种水平井的选斜轨迹设计公式进行了分析对比，建立了9种造斜轨迹的设计通式。 Horizontal well selection material track general ramp, vertical incline point, the target level, steady ramp plus the next ramp, the choice of material plus stability ramp, a single steady ramp, double circular arc ramp, single circular arc ramp and Single arc ramp plus horizontal steady ramp and other 9 types. In this paper, the design formulas of the trajectories of the nine horizontal wells are deduced. The design formulas of the inclined trajectories of the nine horizontal wells are analyzed and compared, and the design formulas of the nine kinds of trajectories are established.
