该文以中缅油气管道某隧道穿越工程为例,介绍了斜孔钻探在大型油气管道勘察项目中的实际运用。从工程物探、斜孔钻探方案布置、钻探结果综合分析等几个方面进行了介绍,在高密度电法物探异常区域解释成果的基础上,利用斜孔钻探揭露出了物探异常点的宽度、充填介质等地质信息情况,给隧道穿越的施工阶段提供了详细、准确的勘察成果资料。
This paper takes a tunnel crossing project between China and Myanmar as an example, and introduces the practical application of inclined hole drilling in large oil and gas pipelines survey project. Based on the results of geophysical prospecting, oblique hole drilling scheme layout and comprehensive analysis of drilling results, based on the results of high density electrical method geophysical anomaly area, the use of oblique hole drilling revealed the width of geophysical anomaly points, filling Media and other geological information, to the tunnel through the construction phase provides a detailed and accurate survey results information.
