辽河坳陷变质岩潜山油气藏类型与成藏模式
Types and accumulation modes of metamorphic buried hill reservoirs in Liaohe Depression
摘要
Abstract
On the basis of analysis of the metamorphic buried hill reservoirs in Liaohe Depression,the buried hill reservoirs are classified according to the petroleum enrichment locations and the relationship between source rock and reservoir,and their petroleum accumulation modes are discussed. The results show the buried hill reservoirs can be divided into buried hill top reservoirs and buried hill inner reservoirs from petroleum enrichment locations of the metamorphic buried hill, and they are also divided into three types of reservoirs from the relationship between source rock and reservoir,that is,the source-under type,the source-beside type and the source-outside type. There are three types of metamorphic buried hill petroleum accumulation modes, that is, the source-under flow-backward mode,the source-beside providing mode and the source-outside conducting mode. The source-under flow-backward mode has the characteristics of direct contact relationship between source rock and reservoir,the abnormal high-pressure driving and hydrocarbon migrating downward and directly entering reservoir;the source-beside providing mode has the characteristics of direct contact relationship between source rock and reservoir,the abnormal high-pressure and buoyancy driving and hydrocarbon laterally migrating and directly entering reservoir;the source-outside conducting mode has the characteristics of indirect contact relationship between source rock and reservoir, the buoyancy mainly driving and hydrocarbon laterally migrating in a long distance into reservoir.关键词
