- 摘要:
- 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。
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.2012,04(04): 31-33 收稿日期:2011-2-23分类号:TE973.4作者简介:刘秀宝(1983-),男,吉林松原人,助理工程师,2008年毕业于吉林大学工程地质专业,现主要从事长输管道、油气储备库、工业与民用建筑等岩土工程勘察工作.参考文献:
