摘要
利用钻井、测井等资料的综合分析,对渤南洼陷古近系沙河街组四段下亚段的沉积相进行了深入研究,识别出了扇三角洲相、辫状河三角洲相、近岸水下扇相、湖泊相和盐湖相等5种相类型,其中研究区南部以扇三角洲相为特征,北部边缘发育近岸水下扇相,东部和西部均发育辫状河三角洲相,中部发育湖泊相和盐湖相沉积,为该亚段油藏开发地质论证提供了理论依据。
The sedimentary facies of the lower IV interval of the Shahejie Formation in Paleogene in Bonan sag are studied through comprehensive analysis of drilling and logging data Five facies are identified including fan- delta, braided river delta, near- shore submarine fan, lake and salt -lake. Fan - delta facies exists in the south of the study area; near- shore submarine fan facies exist at the northern margin; braided river delta facies in the east and west; while lake and salt - lake facies developed in the central part. These studies provide a theoretical basis for development geological study of reservoirs in this interval.
