一种随钻安装测斜仪
摘要：
本发明公开了一种随钻安装测斜仪，包括柔性万向节、柔性钻杆及钻头，所述的柔性钻杆一端与柔性万向节连接，另一端与钻头连接，所述的柔性钻杆与钻头的连接端通过测斜筒设有测斜仪。本发明的测斜仪安装在测斜筒内，在超短半径侧钻井开窗作业、造斜钻进作业、水平钻进作业均可实现随钻测量井斜作用，满足对井眼轨迹的精准掌控。
摘要（英）：

The invention discloses an inclinometer installed while drilling. The inclinometer comprises a flexible universal joint, a flexible drill rod and a drill bit, one end of the flexible drill rod is connected to the flexible universal joint, and the other end of the flexible drill rod is connected to the drill bit, and the connecting end of the flexible drill rod and the drill bit is provided with aninclinometer body through an inclinometer cylinder. The inclinometer body is installed in the inclinometer cylinder, the effect of measuring well deviation while drilling can be achieved during ultra-short radius side drilling window opening operation, deflecting drilling operation and horizontal drilling operation, and accurate mastering of a wellbore trajectory is realized.
