石油管道红水河穿越的工程地质问题分析

以某石油管道红水河穿越工程为例,从穿越断面的工程地质条件及场地环境评价方面进行研究,结果表明,穿越段勘察深度范围内具备定向钻穿越条件,可选用灰岩层作为水平穿越层；同时穿越段的灰岩层溶蚀作用强烈,为岩溶发育地区,在施工时应防止漏浆及卡钻事故的发生.

Engineering Geology Problem Analysis of Oil Pipeline Crossing Red River

Taking the project of oil pipeline crossing the Red River as an example,this paper does the research from the aspects of engineering geological conditions of the crossing profile and site environmental evaluation.The results show that the formation within the investigation depth is suitable for the directional drilling,the limestone layer can be selected as the horizontal crossing layer of the pipeline.At the same time,the dissolution of the limestone layer where the pipeline passes is rather strong due to being in karst development area.Therefore,the slurry leakage and drilling stuck should be prevented in the pipeline crossing construction.
