摘要:
鄂尔多斯盆地西缘奥陶系烃源岩及其生烃潜力的研究程度低,一直是困扰油气资源评价和勘探进展的瓶颈。采用有机岩石学和地球化学实验方法,系统剖析了研究区奥陶系烃源岩的特征和生烃潜力。研究表明,其奥陶系烃源岩主要发育在克里摩里组和乌拉力克组,为一套分布广、厚度大的深海相泥页岩和泥质碳酸盐岩沉积。烃源岩有机质丰度高,有机质类型主要以Ⅰ型为主,Ⅱ1型次之,有机质热演化已达到高成熟—过成熟阶段,具有很好的生烃潜力,天环中区惠探1井—那1井—地鄂3井一线的南北带为生烃中心,是下一步勘探的重点方向。
Abstract:
It has been a bottleneck in oil and gas resources evaluation and exploration progress for low studied degree of the Ordovician source rocks and hydrocarbon?generated potential in western margin of Ordos basin. This paper systemically analysed the general characteristics and hydrocarbon?generated potential of them by means of organic petrology and geochemistry methods. The study shows that the Ordovician source rocks are mainly developed in Kelimoli formation and Wulalike formation in this basin, which is a set of deep marine shale and muddy carbonate rocks of wide distribution and large thickness. The Ordovician source rock is characterized by high abundance of organic matter, kerogen type?Ⅰfollowed by type?Ⅱ1 and high to over maturity stage, with good hydrocarbon potential, and the hydrocarbon generating centers of the north?south belt crossing Tianhuan central district Huitan?1well?Na?1well?Di’e?3well could be the favorable exploration targets in the future
