多管组合穿越工艺研究

Process Design of Multiple Combination Pipe Crossing

本管道穿越技术在大型管道工程建设中应用较多，但多管组合穿越目前应用不多。本文着重从定向钻穿越三个主要环节着手，介绍多管组合穿越的特点，提供具体的设计方法。

the techonology of Pipeline Crossing is much applied in the construction of large-scale pipelines, but multiple combination pipe crossing is merely applied at present.This paper emphersizes the three main components of directional drilling crossing, introduces the characterastics of multiple combination pipe crossing, and then provides the specific design methods.
