摘要
因出砂、套管垢沉积、落物、注灰等原因常造成钻杆卡钻,导致油水井报废。钻杆做为落物,其硬度较高,磨铣不易切削,磨铣效率极低。高效铣削式套铣头的研制成功为钻杆的打捞提供了新的途径。该工具已在中原油田3-251井、3-153井应用成功。
Many reasons like out sand,deposition of case dirty,falling things and cement injection can cause the drill pipe sticking and the well abandoned.The pipe is too hard to be milled easily which makes the efficiency of it to be low.The success research of high efficiency milling washover head provides a new way for fishing pipes. this tool has been applied successfully in well 3-251,3-153 of zhongyuan oilfield.
