墨西哥bano-Pánuco-Cacalilao区块白垩系地层沉积相研究
|
摘要
墨西哥是世界主要产油国之一,海相碳酸盐岩地层分布广泛。储层是形成大型碳酸盐岩油气田的关键因素,EPC区块位于Tampico盆地,白垩系的海相碳酸盐岩是其主要的含油气储层。利用岩心、薄片、测井、地震资料,结合前人研究成果对EPC区块白垩系的主要储层进行了研究,通过分析岩心和薄片资料,确定区域地层的岩石学特征,在此基础上,结合威尔逊的碳酸盐岩沉积模式确定了白垩系地层岩石相(沉积相)展布特征和发育模式。
Mexcio is one of the principle oil producing country with abundant marine carbonate rocks.Reservoir is the key for formation of huge carbonate oil and gas field.EPC area is located at Tampico basin and the Cretaceous marine carbonate rock is the main reservoir.Based on core,thin section,logging and seismic data and the previous research on this area characteristics of the regional strata are defined.On this basis,facies distribution and sedimentary model of the Cretaceous carbonate rock is lineated according to Wilson's carbonate rock depositional model.
