大民屯凹陷基岩经历了40余年的勘探,经历了储量突飞猛进的增长时期,也出现过勘探相对低迷时期,每次地质认识的提升、勘探技术的改进,都实现了储量突飞猛进的增长。本文全面系统回顾大民屯凹陷基岩油气勘探历程、总结重大发现的经验,对大民屯凹陷基岩油气勘探具有十分重要的意义。并对近年来取得的勘探成果及勘探实践进行分析总结,阐明了下步勘探方向。 The bedrock of the Damintun Depression experienced more than 40 years of exploration, experienced a period of rapid growth of reserves, and also experienced relatively downturns of exploration. Each geological improvement and exploration technology improvement achieved rapid growth in reserves. This paper systematically reviews the hydrocarbon exploration process of bedrock in Damintun depression and summarizes the experience of major discoveries, which is of great significance to the exploration of bedrock hydrocarbon in Damintun depression. The exploration results and exploration practices obtained in recent years are analyzed and summarized, and the exploration direction for the next step is clarified.
