地表及地下构造的复杂性使库车复杂山地陡构造圈闭落实面临诸多难点。2005年以来,对复杂山地地震勘探技术,尤其是地震采集及速度精细建模技术进行了重点攻关研究,最终形成了一套系统的复杂山地构造圈闭落实方法,即用复杂山地地震采集技术锁定构造样式,用表层速度反演建模技术、t0漂移校正技术等变速成图技术体系落实高陡构造圈闭,并在构造主体部位用叠前深度偏移成果进行对比验证,以达到提高复杂山地构造圈闭落实精度的目的。该方法在塔里木复杂山地的推广应用取得了良好的效果。
The complexity of the surface and subsurface structures makes it difficult for the Kuqa complex mountain steep structural trap to be implemented. Since 2005, the research on complex mountainous seismic exploration techniques, especially the seismic acquisition and velocity fine modeling techniques has been carried out. Finally, a systematic and complicated method for the implementation of complicated mountain structural traps has been established, that is, the technique of complex mountain seismic acquisition Structure style, surface velocity inversion modeling technology, t0 drift correction technology and other variable speed mapping technology system to implement high-steep structural traps, and the main body of the structure with pre-stack depth migration results for comparative verification in order to improve the complex mountain The purpose of constructing trapping accuracy. The method has achieved good results in the popularization and application of complicated mountainous areas in Tarim.
