摘　　要：运用岩相分析和三维地震精细解释等技术,开展了河125断层对滑塌浊积体沉积的控制作用研究。研究发现:河125断层继承性活动诱发大量滑塌浊积体的形成;断层的几何形态控制着滑塌浊积体的发育规模和位置。最后根据断层对沉积的控制作用落实出滑塌浊积砂体的展布规律,从而加快该区沙三中亚段浊积砂体隐蔽油气藏的勘探部署。Based on such technologies as the analysis of petrographic facies and the fine interpretation of three-dimensional seism, the control function of syndepositional fault that the action of growth fault induces the development of on fluxoturbidite deposition is studied. The study shows slump turbidite and, the scale and position of slump turbidire are controlled by geometric shape of fault. Finally, according to the control function of syndepositional fault on fluxoturbidite deposition, the distribution laws of fluxoturbidite fans are definitely made and the exploration procedure for subtle reservoir of fluxoturbidite fans is advanced in Sha3 middle subsection.
