摘要: 为了克服二维地震资料在复杂构造中的多解性及其造成的砂体预测的不确定性,在沉积相带划分的基础上,利用迁移轨迹和前积结构相结合的方法,对二、三维地震资料进行详细解释,准确预测鄂尔多斯盆地陇东地区延长组砂体分布。研究表明,该区延长组发育有4种类型的前积结构:①S型-透镜状前积具有平坦或略微上升的迁移轨迹,有顶积层,一般发育三角洲前缘亚相,湖底发育泥岩;②S型-楔状前积具有平坦至下降的迁移轨迹,有厚底积层,发育三角洲砂岩和浊积岩;③切线斜交型-板状前积具有下降的迁移轨迹,有顶积层和底积层,发育三角洲前缘和浊积扇;④平行斜交型-楔状前积具有平坦的迁移轨迹,无顶积层和底积层,主要发育三角洲砂岩和砂质碎屑岩。其中S型-楔状前积、切线斜交型-板状前积为三角洲-浊积扇体系,为寻找岩性油气藏提供有利方向。
