井下稳定器安放位置调节器是斜井旋转钻井时实施井斜连续控制的专用工具, 安装在钻头与钻铤之间。正常钻进时, 稳定器至钻头的距离保持不变, 钻具造斜性能相对稳定; 停钻后,通过调整泵压可使稳定器至钻头的距离变长, 也可通过调整钻压使稳定器至钻头的距离缩短, 此伸缩值可由井口测出。现场应用情况表明, 这种调节器能够由地面简单操作改变井下稳定器的安放位置, 使下部钻具结构和造斜性能发生变化, 从而实现井斜连续控制, 避免了反复起下钻和重新组配钻具组合, 具有良好的推广应用前景。
Downhole stabilizer placement position regulator is a special tool for continuous well deviation control in inclined shaft rotary drilling, which is installed between drill bit and drill collar. During normal drilling, the distance from the stabilizer to the drill remains the same, and the drilling tool is relatively stable. When the drilling is stopped, the distance from the stabilizer to the drill can be lengthened by adjusting the pump pressure, and the drilling pressure can be adjusted to be stable The distance from the drill to the drill bit is shortened, which is measured by the well head. The field application shows that this regulator can change the position of the downhole stabilizer by simple operation on the ground and change the structure and the beveling performance of the lower part so as to realize the continuous control of the inclination and avoid the repeated drilling and reorganization With drilling combination, with good prospects for promotion and application.
