摘要

摘要: 利用碎屑锆石U-Pb定年、重矿物组合、成像测井及地震精细解释等技术方法，对东海盆地西湖凹陷中央反转带及其物源区进行源-汇体系分析，研究了中央反转构造带大型储集体的形成过程。花港组沉积时期，中央反转带存在北部虎皮礁、西部海礁隆起与东部钓鱼岛隆褶带3个物源区；中央反转带发育轴向大型通道、西部下切谷通道以及东部隆褶带转换带通道等3种类型的砂体汇聚通道；中央反转带南北向存在北、中、南3个不同的大型砂体汇聚区。在此基础上，综合确定了北部的虎皮礁隆起物源砂体的长距离搬运以及西部海礁隆起与东部钓鱼岛隆褶带的物源点输入为特点的大型储集体形成特征。

Abstract: Detrital zircon U-Pb dating, heavy mineral assemblage, imaging logging and seismic interpretation were applied to analyze the source to sink system in the Central Inversion Belt of the Xihu Sag. The formation process of large reservoirs in the Central Inversion Belt was studied. During the depositional period of the Huagang Formation, there were three provenance areas in the Central Inversion Belt, including the Hupijiao Uplift in the north, the Haijiao Uplift in the west and the Diaoyu Island Transitional Belt in the east. Three source channels for sand import developed in the Central Inversion Belt, including the large axially channels, the incised valley channels in the west and the channels in the Diaoyu Island Transitional Belt in the east. The Central Inversion Belt has three different large sand body convergence areas in the north, center and south. On this basis, the long-distance transportation of source sand in the Hupijiao Uplift in the north and the point source input in the Haijiao Uplift in the west and the Diaoyu Island Transitional Belt were comprehensively determined.
