摘要: 随着岩性圈闭勘探的深入,常规物源分析方法已经不能满足油气勘探的需求。根据“动态物源”概念,建立了精细刻画“动态物源”系统的研究方法,丰富了物源分析方法体系。该方法从层序界面识别、体系域划分等层序地层学研究入手,结合压实校正、古水深校正等条件的约束,利用地层定量回剥技术恢复不同体系域沉积初期的古地貌,并通过刻画各体系域沉积初期物源区的面积来判断物源供给量的相对大小,从而达到预测储层发育位置的目的。该方法在琼东南盆地崖南凹陷东南部的陵一段进行了应用,发现该区域在低位体系域时期发育面积较大的局部物源,它所提供的砂体,形成了较大规模的扇三角洲岩性圈闭,该圈闭成藏条件较好,有望成为崖南凹陷岩性圈闭勘探突破的目标。
