摘要
根据录井、测井、岩心资料对靖边地区侏罗系延安组延9油层组的沉积微相进行划分,并通过连井剖面分析了河道砂体的展布特征。结果表明,延9油层组的沉积相为三角洲平原沉积,其微相类型包括分流河道、分流间湾、决口扇和天然堤等。结合现有勘探成果与构造发育情况,对靖边油田西部地区构造上的岩性油气藏勘探有利区带作了初步预测。
According to logging and core data,the sedimentary microfacies of Yan 9 oil-bearing formation of Jurassic Yan′an Formation in Jingbian area are divided,and the distribution characteristics of channel sand bodies are analyzed through well connection profile.The results show that the sedimentary facies of Yan 9 oil-bearing formation is delta plain,and its microfacies include distributary channel,distributary bay,crevasse splay and natural levee.Combined with the existing exploration results and structural development,the favorable zones for lithologic oil and gas reservoir exploration in the western area of Jingbian Oil Production Plant are predicted.
