珠三坳陷 WC 反转背斜构造的形成与油气成藏
THE FORMATION OF WC REVERSAL ANTICLINE STRUCTURE AND HYDROCARBON RESERVOIR FORMATION IN ZHU Ⅲ DEPRESSION
摘要
Abstract
There is great hydrocarbon generating potential in Wenchang Formation and Enping Formation of Zhu Ⅲ Depression in western area of Zhujiangkou Basin, but no significant exploration discovery has been made due to insufficient understanding of hydrocarbon transportation and accumulation. Based on the understanding of WC-A,WC-B and WC-C sag, large scale industrial cartography, structural characteristics research and regulation of hydrocarbon transportation and accumulation are studied on the basis of fine structure interpretation, and the hydrocarbon distribution and reservoir formation in Zhu IⅢ Depression is better understood. The evolution in WC area takes different progress along with faulting, subsidence and depression of Zhu Ⅲ Depression, which is featured by normal faulting before reverse faulting and forms shallow reversal anticline structure. Through the analysis of matching relationship of WC reversal anticline structure and reservoir formation, it is realized that reversal anticline structure formation is later than substantial hydrocarbon expulsion of source rock and that the source of hydrocarbon is from the redistribution of early hydrocarbon reservoir through late EW and NE faults.关键词
