我队在实现塔上无人的钻探作业中,蘑菇头不下井,常因提引器及垫叉跑位等原因造成跑管事故.防跑管钢体,正是针对这一情况设计的. In the course of realizing the unmanned drilling operation on the tower, the team did not go to the top of the mushroom head, and often caused running pipe accidents due to the puller and the fork running position. The runaway pipe steel body was designed for this situation.
