摘要(Abstract)：

准噶尔盆地车排子地区八道湾组油气勘探取得重大突破,但该地区成岩作用方面的研究还比较薄弱。根据岩石薄片及扫描电镜观察,确定车排子地区成岩作用类型及成岩事件发生顺序;根据阴极发光测试,确定方解石胶结物期次、石英次生加大发育程度及高岭石分布特征;根据X线衍射,确定黏土矿物组成及各矿物成分体积分数;根据氧同位素测试,确定自生方解石形成温度;采用反演回剥法研究储层孔隙演化过程。结果表明:储层主要经历压实作用,方解石、石英、黄铁矿等的胶结作用及长石和石英的溶蚀作用。方解石胶结物形成温度主要介于40~85℃,大致对应早成岩阶段A期的晚期至早成岩阶段B期;黏土矿物以高岭石为主,主要来源于长石的溶蚀;储层孔隙演化过程可以划分为3个阶段,即快速压实阶段、压实胶结阶段及压实溶蚀阶段。该研究成果为车排子地区八道湾组地层油气勘探提供地质依据。
