| description | The invention discloses a shale gas horizontal well continuous fluctuation type reservoir horizontal section geosteering trajectory control method. Identification points are arranged at fluctuation change points of a top interface and a bottom interface of a target layer, an optimal trajectory control path is formed by combining an in-target point and an out-target point, the well deviation angle of the trajectory reaching the in-target point and the well deviation angle required by the front point reaching the rear point in each section are obtained by matching with corresponding formulas, and the geosteering trajectory control of the continuous fluctuation type reservoir horizontal section is realized. The control method is simple, the engineering curvature is optimized, the trajectory adjustment frequency is low, the drilling route is short, and the drilling quality and the drilling time are improved.
本发明公开了一种页岩气水平井连续起伏型储层水平段地质导向轨迹控制方法，通过在目的层顶界面和底界面的起伏变化点处设置标识点，结合入靶点和出靶点形成最优的轨迹控制路径，配合相应公式获得轨迹到达入靶点井斜角和每个分段中 |
