定向穿越技术优化的探讨

Probe into Directional Crossing Pipeline Technology

该文就燃气管道定向穿越工程中,当穿越出、入点和深度确定后,如何进一步优化该技术,着重分析穿越管的实际综合应力和钻机回拖力、探讨穿越过程对不同材质管道防腐蚀层的影响以及穿越过程中对泥浆质量的控制。

In order to optimize this technology when inlet,outlet and deepness determined during gas pipeline direc- tional crossing,actual synthetic stress of crossing pipeline and drilling rig return of trailer are analyzed and effect of anti-corrosion coating for different material pipeline and control of mud quality during pipeline crossing construction are probed.
