江苏油田自1978年开始进行摩擦对焊钻杆工艺试验,在MCH-Ⅱ型摩擦对焊机基础上进行改进设计,经反复试验,于1982年投入使用,截至1985年8月共对焊钻杆接头7460只,累计修复钻杆40000多米,配给5个钻井队使用,共钻井50000余米,使用情况良好,没有出现过钻杆折断事故。这批修复钻杆不仅适应了喷射钻井的需要,还不同程度经受了顿钻的考验,如3291钻井队所配的一套摩擦对焊修复钻杆,在一次顿钻事故中,有一根钻杆被顿弯,但所有焊缝处仍完好无损。
Since 1978, Jiangsu Oilfield has carried out the frictional butt welding drill process test. Based on the MCH-Ⅱ friction butt welder, the improved design was carried out. After repeated tests, it was put into operation in 1982. As of August 1985, 7460 joints, the cumulative repair drill more than 40,000 meters, allocated to the use of five drilling crew, a total of more than 50,000 meters drilling, the use of good condition, there has been no broken drill pipe accident. These rehabilitated drill rods not only meet the needs of jet drilling, but also to a certain extent to withstand the test of Dayton, such as the 3291 drilling team with a set of friction welding repair drill pipe, in a drill accident, there is a drill pipe Beat, but all welds are still intact.
