摘要:
湖底扇砂体是较为有利的油气储集体,深入研究其沉积特征对油气勘探具有重要意义。 以中非 BG盆地 BN 区块下白垩统 P 组为例,在沉积岩石学及层序地层学理论基础上,对该组岩心的沉积构造、测井曲线组合形态和地震剖面响应特征进行分析,并对区域地质特征进行研究。 结果表明:中非 BG 盆地BN 区块下白垩统 P 组属于湖底扇沉积,自下而上表现为正旋回沉积序列,一般发育内扇、中扇和外扇等3 种亚相,以及分支水道、水道侧溢天然堤与无水道前缘席状砂等微相类型; P 组湖底扇砂体受重力流作用控制,主要沿北东—南西向延伸,总体呈扇形展布,其中,中扇分支水道的砂体顶、底常被灰黑色泥岩包围,具备较好的油气富集条件;湖底扇的物源主要来自盆地东北部,于盆缘先形成较大规模的扇三角洲沉积体系,后以浊流的形式被搬运至前三角洲或更远的深水湖区,最终形成湖底扇沉积体系。 P 组有利储层主要分布于盆地北部陡坡带断层下降盘一侧湖底扇的内扇水道和中扇分支水道砂体中。
