摘要
目前定向钻穿越技术已经得到了广泛应用,而多管组合穿越以其特有的经济及环保优势,正逐步推广开来。针对多管组合穿越的特点,对单管穿越的回拖力计算方法进行了改进,使其适用于多管组合情况下的管道穿越,为多管组合穿越提供了一定的理论指导。
Directional drilling technology has been widely applied and multiple pipes combination crossing will also be gradually adopted for its unique economic and environmental advantages. According to the features of combination of multiple pipes, calculation methods of back dragging forces have been improved and become more adoptable in multiple pipes combination crossing, which would be of instructive significance.
