摘要
四川盆地蜀南地区下二叠统茅口组为典型的碳酸盐岩缝洞型储层,具发育程度不完全受构造控制。该区储层具有低孔低渗、非均质性强的特点,单纯基于速度反演的预测难度较大。通过波动方程正演分析及多种储层预测参数在该区适应性的联合研究,获得了蜀南地区茅口组有效的储层预测方法,对其油气勘探与开发具有重要的指导意义。
The lower Permian Maokou Formation,southern Sichuan Basin,is a typical carbonate fractured- and- vuggy reservoir. And its development degree is not affected by structure. In addition,it is characterized by low porosity and permeability,and strong heterogeneity. So,it is very difficult to carry out its prediction only based on velocity inversion. In this study,a method to predict effectively Maokou reservoir was gained based on the analysis of wave- equation forward modeling and the study of some prediction parameters adapting to this area.
