摘　　要：在碳酸盐裸露、厚黄土覆盖和山前带等地表条件异常复杂地区,传统三维地震勘探无法有效开展。为查明这类地区煤系地层及构造发育情况,对三维Reverse Vertical Seismic Profile(以下简称RVSP)技术进行系统深入地研究,突破RVSP技术在数据采集、处理方面的难题,并成功在某煤矿进行应用,共完成全区8个孔位的数据采集工作,完成采样物理点438个,合格率100%。对采集的数据进行静校正、RVSP-CDP等效地面变换等处理后,开展相关解释工作,控制煤层断层38条,较好地控制了3#、5-3#、6-3#、8#等主要煤层底板深度和起伏形态,取得较好的效果。Traditional 3D seismic cannot be effectively carried out in these areas such as bare carbonate,thick loess and piedmont areas.In order to ascertain the development of coal measure strata and structures in such areas,the 3D Reverse Vertical Seismic Profile technology was studied,which has broken through the current difficulties in data collection and processing of RVSP technology.The 3D RVSP technology was successfully applied in a mine and data collection of 8 holes and 438 physical points were completed.The pass rate was 100%.After processing the data such as static correction and equivalent surface seismic data processing,the interpretation work was carried out.38 coal seam faults were controlled and the depth and undulation of the main coal seams 3#,5-3#,6-3#,8#were well controlled.The application effect is better.
