虎头山定向钻穿越实例分析

Example Analysis of Hutou Mountain

山区油气管道的设计和施工一直是管道建设中较为棘手的问题,利用定向钻穿越非灰岩地质的山体,是近年来多家设计和施工单位在摸索和试验的一种非开挖施工方法;山体定向钻可以减少对原生地形地貌的破坏,减少对地表植被的破坏,有利于环境保护和降低管道山区施工困难。本文为山体定向钻探索性试验项目,施工方案的成功,可以为类似地形地质条件下的山区管道设计提供一定参考价值。

The design and construction of oil and gas pipeline in mountainous areas has always been a difficult problem in pipeline construction. Using directional drilling through non-limestone geology is a trenchless construction method explored and tested in recent years;directional drilling can reduce the damage to native topography,surface vegetation,facilitate environmental protection and reduce the difficulties of pipeline construction.This paper is a simple test project for mountain directional drilling. The success of the construction scheme can provide some reference value for mountain pipeline design under similar topographic and geological conditions.
