摘要
为扩大勘探领域 ,寻找新型油气藏 ,丰富碎屑岩盆地的石油地质理论及渤海湾盆地复式油气聚集理论 ,本文应用沉积压实研究成果及综合地质分析方法 ,对博兴洼陷高 7井泥岩裂缝含油气段进行了分析和研究。结果认为 :高 7井为“砂泥孔缝等压渗储与泥盖”、自生自储型特种油气藏 ,泥岩裂缝是其成藏的关键 ;主控因素为岩相与断裂分布 ;该类油气藏是纯梁油区及东部老油区扩大勘探领域、寻找新型油气藏的重要潜力区 ,今后应加强对该区的研究工作。
To enlarge exploration field, find new type of reservoir and complement petroleum geological theories of clastic basin and complex hydrocarbon accumulation concepts of Bohai bay, sedimentary compact research and comprehensive geology analysis are utilized for fracturized mudstone pay zone of Gao 7 well, Boxing sag. It demonstrated that Gao 7 well penetrates through a special reservoir features selfgeneration and self-accumulation whose mudstone fractures are essential reservoir forming condition,and facies and fractures distribution as dominant factors. This type of reservoir is main potentialprospect and enough emphasis should be paid for its future study.
