摘要: 海拉尔断陷盆地贝尔断陷兴安岭群和南屯组具有多物源、小断块、构造期次复杂、沉积岩中含有火山碎屑夹层和凝灰质砂砾岩等特征。针对油区内凝灰质储层相变大、标志层不稳定、断层多而小、地层顶面剥蚀大、上下两套地层沉积体系不同的特点,利用高分辨率层序地层的地质成因—沉积响应分析方法,对贝尔断陷兴安岭群和南屯组的沉积体系划分、地层基准面对储层物性的控制、区域性标志层的寻找进行了详细分析,并总结出复杂地质条件下的层序地层分析方法。

Abstract: By analyzing the sedimentary systems of Xing'anling Group and Nantun Formation in Beier fault-depression, Hailaer Basin, being featured with multiple-source, small faults, complex structural epochs, and sedimentary rock with volcaniclastic rock interlayers and tuffaceous conglomerates, the geological genesis-sedimentary response analysis method of high-resolution sequence stratigraphy is applied to divide the sedimentary systems, determine the control of geological base-level on the reservoir's physical property and seek for regional index horizon, aiming at the features of tuffaceous reservoir in this area including obvious facies variation, non-stable index horizon, many faults and their scale being small, the top surface's denudation being serious and sedimentary systems between the top and the bottom being different. Sequence stratigraphic analysis method is summarized in the case of complex geology.

Key words: rift basin, high-resolution sequence stratigraphy, sequence analysis for residual basin, sub-bed division, reservoir physical property, index horizon
