摘要
泥岩裂缝油气藏作为隐蔽油气藏的一种,在国内外含油气盆地中都有发现。本文利用岩石学、测井、区域地质等资料,对辽河断陷盆地泥岩裂缝油气藏的形成机制及勘探意义进行了研究。结果认为:异常超压带和大的构造断裂带控制泥岩裂缝油气藏的分布;在异常超压带和大的构造断裂带附近泥岩裂缝油气藏较为发育;泥岩裂缝油气藏的油气以自生自储式为主:泥质岩油气藏作为值得重视的一个勘探新领域,具有较好的勘探前景。
As one of the subtle reservoirs, fractured shale reservoirs have been discovered in hydrocarbon bearing basins at home and abroad . By using data of petrology, logging and areal geology, this paper studies the forming mechanism and exploration signillcance of such reservoirs in Liaohe Basin. The result is that abnormal pressure zone and large structural fault zone controlled the distribution of such reservoirs , and such reservoirs were more developed in such zones. Oil and gas in such reservoirs were mainly authigenic. Argillaceous reservoir is a new exploration region worthy of attention and has good exploration prospect.
