摘要: 为研究鄂尔多斯盆地陇东地区长4+5油层组的沉积相展布特征,开展了野外露头剖面和钻井取心的岩心观察、铸体薄片鉴定、重矿物测试、测井岩电关系分析等工作。结果表明:①陇东地区长4+5油层组的沉积主要受东北、西南和南部共三大物源区控制;②研究区主要发育3类沉积相,东北部为曲流河三角洲相,西南部和南部均为辫状河三角洲相,中部为湖泊相,可进一步将其划分为5类亚相和10类微相;③研究区长4+5油层组主要表现为"湖退-砂进"的沉积特征,长4+51小层沉积时相对于长4+52小层沉积时的湖盆面积较小,砂体规模更大;④相对于西南部和南部,东北部的物源供给更充分,多支水下分流河道汇聚于此,叠置连片分布的厚层砂体更为发育。该研究成果展示了陇东地区长4+5油层组的勘探潜力,可为下一步精细勘探提供借鉴。
