摘要
以冀中坳陷任丘碳酸盐岩潜山和辽河坳陷兴隆台变质岩潜山为例,探讨了渤海湾盆地大型潜山油气藏形成的有利因素。研究表明:渤海湾盆地已发现潜山油气藏111个,层位从太古宇变质岩至古生界碳酸盐岩;任丘碳酸盐岩潜山和兴隆台变质岩潜山风化剥蚀时间长、断裂活动强度大;"洼中隆"的构造格局、"多对一"的源储关系、厚度大的储层条件、多类型的圈闭条件和源储直接接触关系以及大面积的供烃窗口是大型潜山油气藏形成的有利因素。
Taking buried hill of carbonate rock of Rengqiu,Jizhong Sag and buried hill of metamorphic rock in Xinglongtai,Liaohe Sag as example,favorable factors for the accumulation of large-scale buried hill gas reservoirs in Bohai Bay Basin are discussed.Research indicates that,111 buried hill oil/gas reservoirs have been discovered in Bohai Bay Basin. Horizons are from metamorphicrock in Archean to carbonate rock in Palaeozoic Erathem. As for buried hill of carbonate rock in Rengqiu as well as metamorphic rock in Xinglongtai,the time of weathering and erosion is long and the strength of fracturing is large. 'Uplift in sag'structure,'multiple-to-one'relationship between sources and reservoir,large thickness of reservoir,multiple types of trap conditions as well as direct contact between sources and reservoir and large area of hydrocarbon provision window are the favorable factors to the forming of large-scale buried hill reservoirs.
