摘要
常规表层结构调查方法如小折射和微测井等 ,都是解决一个点上的问题。利用间隔较大的多点测量对速度界面进行划分 ,不能准确确定表层的岩性界面和结构 ,对岩性的分析存在多解性。地质雷达探测是利用不同界面的电性差异 ,反映岩性变化的特征。胜利油田利用地质雷达技术探测近地表层的结构及其形态取得了一定的效果
Conventional surface structure survey methods such as weathering refraction shooting and uphole shooting are restricted to a certain point. The measurements from sparsely distributed points can not yield accurate surface lithologic interfaces and structure. Ground penetrating radar (GPR) surveys the electricity differences of different interfaces that reflect lithologic variations. GPR was used in the investigation of near surface structures. Satisfactory results have been yielded.
