围绕川东北吴家坪组烃源岩的形成环境和资源潜力等问题,基于钻井和露头剖面资料及地球化学资料,重点探讨了川东北地区吴家坪组烃源岩的品质、规模及生烃潜力。研究表明,川东北地区吴家坪组烃源岩的发育显示出强烈的非均质性,表现为多元的有机质类型和不稳定的时空展布。在吴家坪期,川东北巴中—达州一带沉积了富含Ⅰ-Ⅱ型有机质的黑色页岩和泥灰岩等,发育了一套海相优质烃源岩,生烃潜力高,倾油型,是川东北地区内一个重要的生烃中心,可为川东北长兴组—飞仙关组的油气藏提供丰富的物质基础。

英文摘要：

Hydrocarbon-generating potential and sedimentary environments of the hydrocarbon source rocks of the Upper Permian Wujiaping Formation in the northeastern Sichuan Basin are discussed, based on drilling and outcrop sections and geochemical data. This study focuses on the hydrocarbon source rocks quality, scale and hydrocarbon-generating potential. The strong heterogeneity of the hydrocarbon source rocks of the Wujiaping Formation, shows diverse types of the organic matter and unstable time-space distribution. During the Wujiapingian time, black shale and muddy limestone were deposited widely in Bazhong-Dazhou area of the northeastern Sichuan Basin. They are oil-prone organic-rich hydrocarbon source rocks with Ⅰ-Ⅱ type of the organic matter and possess high hydrocarbon-generating potential. The hydrocarbon source rocks can provide rich materials for the oil and gas accumulations in the Changxing and Feixianguan Formations of the northeastern Sichuan Basin. It is an important hydrocarbon-generating center in the Sichuan Basin.
