摘要
针对目前隐伏断层探测中存在的技术难题,提出了在地面反射地震勘探初步确定的断点附近,用井间地震层析成像方法探测隐伏断层及其上断点的埋深。首先介绍井间地震技术的应用现状和井间地震层析成像的基本原理,并结合实例讨论了井间初至走时层析成像的野外数据采集和室内资料处理方法。芦花台隐伏断层的井间地震层析成像结果表明,采用弯曲射线追踪方法反演得到的跨芦花台隐伏断层的井间纵波速度结构图像与钻孔联合剖面揭示的断层特征相吻合。
This paper discusses the problems existed in active-fault exploration, in the area of breakpoint based on ground reflection seismic exploration, making use of Cross-well Seismic Tomography to detect active-fault and determine the depth of Up-breakpoint and deduced its activity era. It describes the application status of the Cross-well Seismic Technology and introduces some algorithm of Cross-well Seismic Tomography, also in actual test; discussed the data acquisition and data processing methods for Cross-well travel time tomography. Using Curved-Ray tracing algorithm obtained the P-wave velocity structure image across the Luhuatai buried fault. This study shows that the result is highly similar to drilling profile.
