井间电磁波CT技术在管道工程岩溶探测中的应用

地下水长期作用于灰岩裂隙往往使岩溶或破碎带更加发育，形成地下溶洞，给地下管道工程带来极大的隐患和危险。为了查明地下岩溶的发育情况，根据不同介质对电磁波的吸收（J8）存在差异，运用井间电磁波法层析技术（CT）探测地下目标地质体的结构和形状。通过在广西西气东输管道工程的应用，结果表明井间电磁波CT技术可为西气东输二线管道工程提供可靠精确的地下地质资料，经钻孔验证，效果良好。为管道工程的施工提供了安全保障。

Application of Well CT Technology to the Detection of Pipeline Engineering Project

The limestone fractures under the ground water often make karst or crushed zones develop faster, so the formed carst caves have brought great hidden trouble to the buried pipe engineering projects. In order to detect how the carst caves develop, the well electromagnetic CT technology is used to detect the structure and shape of underground target geological body. Through the application of West--East gas transmission project, the result shows that the well electromagnetic CT technology can provide reliable and accurate ground geological data for West to East gas transmission pipe 2 project. It is very effective for the safety of the pipeline project.
