摘　　要：近年来,随着勘探开发程度的不断提高,黄骅坳陷孔店-羊三木地区油气勘探开发面临着严峻的油气接替难题,由于该区地下地质条件复杂,基础研究工作相对薄弱(尤其是油气运聚规律研究),已经影响到该区下阶段的精细勘探工作。从多年的勘探实践出发,通过对该区周边的歧口凹陷、盐山凹陷和沧东凹陷3大生烃凹陷的主力生油层系烃源岩评价与油源对比,分析油-岩的对应关系,在已知油气藏剖析的基础上,确定了油气运聚主要方向,研究结果表明,断层、不整合面和渗透性砂体3大输导体是油气富集成藏的关键。该项研究对孔店-羊三木地区下步勘探开发工作具有重要的指导意义。Recent years,with the continuous improvement of the exploration and development,oil and gas exploration and development in Kongdian-Yangsanmu area,Huanghua Depression is facing severe problems of oil and gas succeeding.The complex underground geological conditions of the area,relatively weak on the basic research work,especially oil and gas migration law research,have affected the fine exploration work in the area for the next stage.Setting out from the practice of many years' exploration and through the correlation of source rock evaluation on major hydrocarbon layers and oil-source in Qikou Depression,Yanshan Depression and Cangdong Depression around this area and analysis of correspondence between oil and rock,based on the known oil and gas reservoirs analysis,the authors determined the main direction of hydrocarbon migration and accumulation,the results showed that 3 conductors,the fault,unconformity surface and permeability sand body are the key to oil and gas rich integration.The study has an important guiding significance for the next exploration and development work in Kongdian-Yangsanmu area.
