摘要: 通过综合运用有机地球化学方法,利用实测和收集到的烃源岩数据,对堡古2井的烃源岩进行分析,从有机质丰度、有机质成熟度、热解产率和排烃门限对区内烃源岩进行了评价,研究了该井的有机生烃特征,结果表明,南堡3号潜山发育丰富的烃源岩,有机碳含量高,有机质类型以Ⅱ1、Ⅱ2型为主,烃源岩已不同程度地进入成熟—高成熟阶段。综合分析表明,南堡3号潜山具备一定的生烃条件和油气勘探前景,可作为下一步的重要勘探和开发目标。

Abstract: According to the measured and collected geochemical data, the hydrocarbon source rocks of the Well Pugu 2 are discussed in this paper. Organic matter abundance, organic matter maturity, pyrolysis yield index and the hydrocarbon-expulsion threshold were selected as the standards for source rock evaluation. Results show that the No.3 buried-hill has enough source rocks with high content of organic carbon. The organic matters dominated by types Ⅱ1 andⅡ2 have passed into the mature-high mature phase to different extent. Our study indicates that the Nanpu No.3 burried-hill has enough capability to generate hydrocarbon, and thus can become an important exploration and development target.
