摘要(Abstract)：

以鄂尔多斯盆地海陆过渡相富有机质泥页岩为研究对象,分析野外露头和岩心观察、采样、地化参数和物性参数等测试资料,研究富有机质泥页岩的沉积相、厚度及分布、有机质类型及含量、热成熟度、孔隙度等页岩气成藏条件.结果表明:鄂尔多斯盆地上古生界石炭—二叠系海陆过渡相富有机质泥页岩主要发育在沼泽相和三角洲相,常与煤层、灰岩、致密砂岩等互层,纵横向变化快,单层厚度小,累计厚度大,有机碳含量相对海相、陆相泥页岩较高.有机质类型以腐殖型为主,有机质热成熟度处在成气高峰阶段,有利于页岩气的形成.综合页岩气藏评价的各项指标信息,预测鄂尔多斯盆地石炭—二叠系海陆过渡相页岩气藏最有利发育区位于盆地东部神木—绥德—延长一带的山西组、盆地北部乌审旗—杭锦旗—东胜—神木与鄂托克旗—盐池一带的太原组及盆地东北部靖边—横山—榆林—神木一带的本溪组,虽然各组地层埋深较大,但多与煤层、致密砂岩层互层,形成页岩气、煤层气和致密砂岩气叠置成藏,具有较大的勘探与开发潜力.
