The Kulongshan and Liugouzhuang Oil Reservoirs: A kind of the source rock fractured reservoir of the Qingxi Sag in Jiuxi Depression
-
摘要: 剖析了酒西坳陷青西生油凹陷中发现青西油田的地质背景，研究了青西油田窟窿山和柳沟庒油藏的形成和分布规律及其控制因素，在此基础上提出了青西油田的窟窿山和柳沟庄油藏属于“源岩裂缝油藏”的新认识。同时论证了“源岩裂缝油藏”形成的特定地质条件和研究价值。提出“源岩裂缝油藏”的特殊意义就在于源岩层中可以找到油藏，其发现和深入研究，将进一步拓宽油气勘探领域，丰富石油地质理论，是一项具有重大科学意义和实用价值的研究课题。Abstract: The geological background of finding the Qingxi oil field in the Qingxi petroleum generation sag of Jiuxi Depression are analyzed, the formation and distribution regularity of the Kulongshan and Liugouzhuang oil reservoirs and it's control factor are researched. On the basis of this study, the thesis raised a new viewpoint that the Kulongshan and Liugouzhuang oil reservoirs of the Qingxi oil field should be the source rock fractured reservoir. At the same time, the specially geological condition of the source rock fractured reservoir's formation and it's research value are demonstrated. The specific significance of the source rock fractured reservoir is that the oil reservoir may be found in the source rock, it's finding and an exhaustive research will extend the oilgas exploring area and enrich the petroleum geology theory. It is a new research task which has great scientific significance and practical value.
