燃气管道定向钻穿越卵石层等复杂地层的实践

Practice of Gas Pipeline Directional Drilling Crossing in Complex Stratum Area like Pebble Layer

结合工程实例,论述了天然气管道水平定向钻穿越圆砾层、卵石层、局部溶洞区等复杂多变地层的设计方案与施工方法。

The design scheme and construction method of natural gas pipeline horizontal directional drilling crossing in complex stratum area such as rounded gravel layer, pebble layer and local limestonecave area are discussed with an engineering example.
