水平定向钻施工在软硬分层地质中的风险控制

Risk Control of Horizontally Directional Drilling under the Soft-Hard Stratification Geological Condition

通过对上海市漕廊公路次高压天然气管过沫沥港、秦湾路穿越工程案例进行分析,论述了在软硬分层地质中水平定向钻施工采取的相应改进措施,为以后定向钻穿越同类地质条件的工程提供了有益的借鉴。

By analyzing the engineering project which high-pressure natural gas pipelines cross Qingwan Road, the paper discusses the counter measures taken in the horizontally directional drilling construction under the soft-hard stratification geological condition, and can be as a good reference for the future engineering.
