摘要
Abstract
Based on the comprehensive analysis of cores, drilling well, logging and seismic data, the stratigraphic characteristics and sedimentary evolution in the Member 1 of Paleogene Kongdian Formation in Weibei Sag was analyzed. This study suggests that the Member 1 of Kongdian Formation was divided into 3 sub-members, containing 11 sand sets. Controlled by Tangwu-Gegou fault in the west and Changyi-Dadian fault in the east, the strata developed stably in the east and west, only in the northern sub-sag belt strata became thicker. Controlled by Gucheng-Weihekou fault in the northern Weibei Sag, the strata overlapped towards the south and thinned generally from north to south. Fan delta facies and lacustrine facies mainly developed in Member 1 of Kongdian Formation in Weibei Sag, and delta developed in small scale in the southern slope belt. During the development of the lower submember of Member 1 of Kongdian Formation, sediment supply was abundant, which formed the large-scale fan-deltas in northern sub-sag belt, Wacheng fault-step belt and Zaohu fault-nose belt. During the development of the middle submember of Member 1 of Kongdian Formation, the depth of water became shallower and sediment supply decreased, fan-deltas inherited the development in northern sub-sag belt, Wacheng fault-step belt and Zaohu fault-nose belt, which distributed in small scale. During the development of the upper submember of Member 1 of Kongdian Formation, the depth of water became the shallowest, the whole area developed shore-shallow lacustrine facies, and only small-scale fan-deltas developed in Wells Yangxie 4 and Chang 11.关键词
