【摘要】 应用钻井和地震资料,分析赛汉塔拉凹陷白垩系地层的沉积充填、层序发育特征,建立全凹陷Ⅲ级层序地层充填格架,可以得出以下结论:都如吉洼槽极其周缘Ⅲ极层序S1低位体系域、S2的高位体系域、S3和S4的低位体系域位于有利的生油洼槽,储层发育,是岩性油藏发育的有利层段。更多还原

【Abstract】 Some seismic data and drilling data was used to analyze the sediment filling,the sequence development characteristics of the Cretaceous formation of Saihantala Depression,construct the Ⅲ-order sequences stratigraphic filling frameworks,estimate the distribution characteristics of sand bodies,the favorable zones and areas where some litholigic oil pools developed, provide scientific basis for discovering new oil &gas fields in Jianghan exploration area of Saihantala Depression.更多还原
