摘要
Based on seismic,drilling and geological data,the structural styles are systematically identified in study area.Through the analysis of internal deposit types and migration pathways of all kinds of structural styles,this paper researches the control action of the structural styles on hydrocarbon distribution.The research results show that four types of stretch structure styles,including warped pour block,sliding step,buried hill with overlying and gravity antiformal,developed in Cainozoic in Zhanhua Depression.The distributions of various structural styles show obvious regularity.Different kinds of structural styles contribute differently in migration and accumulation of hydrocarbon.The warped pour block and the sliding step are the favorable channel of hydrocarbon migration towards basin edge.The hydrocarbon is most easily enriched in the cut barrier block as well as the buried hill with overlying.The hydrocarbon enrichment in the gravity antiform can be affected by scale,oil source,reservoir development degree.
