For this reason,the landing nipple without angle difference used for directional drilling of deviated well track is developed based on the previous landing nipple. The piston and main body of the previous nipple are improved by using splined piston matching structure,which overcomes the shortcoming of the previous nipple.
针对这种情况,在原有定向接头的基础上,研制出用于斜井轨迹定向钻进的无角差定位接头,即对原接头的活塞和主体加以改进,采用花键式活塞配合结构,克服了原定位接头的不足。
