变换带是构造变形区调节构造平衡的重要地质构造。金湖凹陷西斜坡存在崔庄变换带,为了研究崔庄变换带的地质特征及其与油气藏的关系,分析了西斜坡构造演化历史、断层生长特征及沉积相分布规律,在此基础上,研究了变换带的构造分区、沉积分区作用及其与油气藏的对应关系。结果表明,金湖凹陷西斜坡崔庄变换带是控制阜宁组油气藏的重要因素,古近纪阜宁期是崔庄变换带发育的主要时期,变换带是凹陷侧向物源的入口,控制砂体的展布方向,并且是西斜坡南北分区的界限,变换带两侧构造、沉积存在很大差异。变换带的砂体连通性好,是有利的油气聚集区带,崔庄变换带兼具油气运移和储集的双重作用。
The transformation zone is an important geological structure that tectonic deformation zone tectonic balance. In order to study the geological characteristics of Cui Zhuang transform belt and its relationship with oil and gas reservoirs, the Cui Zhuang transformation belt exists in the western slope of Jinhu Depression. Based on the analysis of the tectonic evolution history, fault growth characteristics and sedimentary facies distribution of the western slope, The tectonic zonation of the transformation zone, the role of sedimentary division and its corresponding relationship with the reservoir are studied. The results show that the Cui Zhuang transformation belt on the western slope of Jinhu depression is an important factor for controlling the Funing Formation. In the Paleogene, the Funing Period was the main period for the development of Cui Zhuang transformation zone. The transformation zone was the entrance of the lateral source of the depression, It controls the distribution direction of the sand body and is the boundary of the north-south division of the west slope. There are great differences in the structures and sediments on both sides of the transformation zone. The sand body of the transformation zone has good connectivity and is favorable for the hydrocarbon accumulation zone. The Cui Zhuang transformation zone has both dual functions of hydrocarbon migration and accumulation.
