准噶尔盆地陆东—五彩湾地区石炭系烃源岩
Petroleum Exploration and Development（2010）
Abstract
陆东—五彩湾地区天然气具有典型的源控成藏特征,将露头资料、钻井资料和地震资料相结合,对陆东—五彩湾地区石炭系烃源岩的丰度、类型、成熟度特征进行了系统研究和评价。研究区石炭系烃源岩以深灰色泥岩和灰色泥岩为主,其次为凝灰岩、炭质泥岩、粉砂质泥岩和煤;上石炭统巴塔玛依内山组(C2b)烃源岩丰度高于下石炭统滴水泉组(C1d),下石炭统烃源岩的类型好于上石炭统;石炭系烃源岩成熟度高值区分布在滴南凸起西段—五彩湾凹陷一带,向南、北方向石炭系烃源岩的成熟度降低;石炭系烃源岩与火山岩的分布具有互补性,烃源岩呈东西向带状分布,烃源岩最发育区位于滴南凸起西段及其南部。图8表2参15
