“旋转闭环钻井系统”(Rotary Closed Loop Drilling System)是一种智能化自动化的定向钻井系统。它能在钻柱旋转(即常规旋转钻井)的条件下,自动调整井眼的倾斜和方位,按预定的轨迹(几何导向)或岩层(地质导向)钻成定向井。可谓“从心所欲而不逾矩”——想钻到哪里就钻到哪里而又不出偏差。旋转闭环系统由地面仪器和井底的“导向套”和“测量短节”组成。
“Rotary Closed Loop Drilling System ” is an intelligent and automated directional drilling system. It automatically adjusts the inclination and orientation of the wellbore as the drill string rotates (ie, conventional rotary drilling) to drill directional wells in a predetermined trajectory (geometry orientation) or rock formation (geosteering). Can be described as “do not want to exceed the moment ” - Where you want to drill where you go without deviation. Rotating closed-loop system consists of the ground instrument and the bottom of the “guide sleeve ” and “measuring the short section ”.
