摘要
In order to depict the provenance system of ZaoⅢ reservoir group in southern Kongdian region and predict the sand-body distribution between Zaoyuan and Wangguantun development zones,as well as to promote further exploration and provide a theoretic base for development,Comprehensive application of geophysics,geochemistry and sedimentology to depict precisely the provenance system in ZaoⅢ period is needed.By comprehensive research of regional gravity anomaly,seismic attribute,heavy mineral cluster analysis,light mineral analysis,analysis of debris,and sand-body dispersions system in southern Kongdian,Huanghua Depression,six fans were described precisely in western Cangxian uplift,northern Kongdian Salient and eastern Xuhei Salient.To integrate the relationship among the provenance system,the strata,ancient landform and the structure characteristics,the provenance system in ZaoⅢ period of Kongdian group in southern Kongdian region of Huanghua Depression is controlled by ancient landform characteristics,synchronous fractures and basin margin bedrock.
