摘要(Abstract)：

松辽盆地深层断陷具有数量可观的油气资源。为了深化松辽盆地深层断陷的整体研究,在区域构造背景下,以地震资料为基础,利用平衡剖面技术对断陷类型进行详细划分,并对深层断陷的分布特征及其控制因素进行深入探究。研究结果:从断陷结构的角度,将松辽盆地深层断陷类型分为单断型和双断型两大类,单断持续沉降型、单断剥蚀改造残留型、单断晚期反转改造型、单断后期抬升改造型、双断持续沉降型、双断晚期反转改造型、双断后期抬升改造型7个亚类;根据断陷结构分类、断裂的分布、构造活动对断陷的影响等因素,将松辽断陷自西向东分成西、中、东部3个断陷带;多期构造活动控制断陷的形成与发展,断裂控制断陷的形态、规模和地层厚度。研究成果为松辽盆地深层勘探提供了理论依据。
There are remarkable oil and gas resources in the deep fault depression of Songliao Basin. In order to deepen the overall research on the depression, based on the regional structural background and seismic data, with the help of the profile balancing technique, the fault depression types were divided in detail, and more over the distribution characteristics of the deep fault depression and their controlling factors were deeply studied. The study results show that from the viewpoint of the depression structures, the types of the deep fault depression in Songliao Basin can be divided into two major types and seven sub-types: single-fault continuous subsidence type, single-fault denudation remained type, single-fault late reversal type, single-fault late uplift type, double-fault continuous subsidence type, double-fault late inversion type and double-fault late uplift type; according to the classifications of the fault depression structure, the distributions of the fault and the influences of the tectonic activities on the fault depression, Songliao fault depression can be further divided into three fault zones from west to East: the west, middle and east; the multi-stage structural activities control the formation and development of the fault depression, and the fractures dominate the configuration, scale and stratigraphic thickness of the fault depression. The research results can provide the theoretical evidences for the exploration of the deep layers in Songliao Basin.
