摘要
鄂东气田保德区块产能建设工程已建成输气管道397 km,沿线地形、地质情况复杂,且管道材质轻、管径小,使其沿线的勘察工作具有特殊性和复杂性,成为管道线路勘察的新挑战。从勘察目的、技术要求、勘察手段、勘察要点等多方面入手,着重分析了对管道设计、施工影响较大的工程地质问题,从而对黄土地区煤层气管道线路工程的勘察进行全面的技术总结,以期为以后同类线路勘察工作提供依据和借鉴。
The productivity building project for Block Baode, Eastern Ordos Gasfield, has constructed pipelines with total length of 397 km. Complicated topographic and geologic conditions are distributed along the pipelines. In addition, the pipelines are characterized by light materials and minor diameters. Consequently, route surveys may usher in a new area that involves certain particularity and complexity. Techniques deployed for survey of coal bed methane （CBM） pipeline routes in loess areas are summarized in aspects of objectives, technical requirements, techniques and key points for such surveys. Additionally, engineering geologic conditions that may have significant impacts on pipeline design and relevant construction activities are highlighted. Relevant research results may provide foundations and references for route surveys for similar pipelines in the future. （12 References）
