摘要

摘要: 东海陆架盆地是中国近海最大的沉积盆地，而西湖凹陷又是其中规模最大的富油气凹陷。多年的勘探实践证明渐新统花港组为西湖凹陷主力产气层段，但其层序地层划分长期存在较大争议。在分析了西湖凹陷盆地结构与构造格局的基础上，依据测井、岩芯以及地震反射特征，将西湖凹陷渐新统划分出5个三级层序与12个体系域，建立了其等时地层格架；并通过大量岩芯的写实性描述，结合沉积构造与遗迹化石鉴别以及地球化学资料分析对沉积环境进行了判识，分析结果认为西湖凹陷渐新统花港组沉积时期发生过两次较大的海侵事件，形成“南海北陆”的沉积格局，并发育了河流、三角洲、潮控河口湾以及无障壁海岸四种沉积体系，其沉积体系类型较多，从南到北变化巨大。西湖凹陷渐新世整体表现为“东西短轴三角洲”、“南部潮汐河口湾”、“东北缓岸滩坝”的沉积体系展布格局。系统分析了沉积相在各层序中的展布特征及其对海平面变化的响应、层序演化过程及其对海平面变化的响应，构建了东海陆架盆地西湖凹陷构造-沉积成因模式，明确了“断坳转换，海陆交替”的盆地构造背景与沉积充填的响应关系。

Abstract: The East China Sea Shelf Basin (ECSSB) is the largest sedimentary basin in offshore China, which contains the largest hydrocarbon bearing unit of Xihu Depression. However, after years of exploration practices, the Huagang Formation in Oligocene has been proven as a major gas reservoir, which has undergone controversy on subdivision of sequence stratigraphy and types of sedimentary systems for a long time. Combining with basin structure and tectonic context, this study subdivides the Oligocene into 5 third-order sequences and 12 system tracts in the Xihu Sag on the basis of base level cycle analysis, core calibration, and seismic reflection features.Furthermore, sedimentary environments were identified by core description, sedimentary structures, trace fossils, and geochemical analysis. Typical sedimentary sequences were established including fluvial, delta, tidal estuary, and beach-bar systems.Sedimentary system types and distribution have been clarified of the Huagang Formation in the Xihu Sag. In the Oligocene, the Xihu Sag was in a transitional environment (mainly in lacustrine environment), which experienced two major times of marine transgressions (around 29.5 Ma and 24.3 Ma). Depositional systems were diverse from south to north, mainly consisting of deltas in the short axis from east to west, tidal estuaries in the south, and beach-bars in the northeast gentle slope. Finally, tectonic-sedimentary genetic model has been established in the ECSSB, showing basin tectonic setting and depositional response under the context of rifting-depression transition and marine-continental alternation.
