摘要:
以伊拉克M油田碳酸盐岩油藏为例,裂缝的发育大大改善了其储层的渗流能力,要反映出整体的渗流特征必须要建立准确的双重介质模型。在精细地层格架搭建的基础上,通过数据分析和方法优选,进行相控基质属性建模。根据岩心观察、成像测井、镜下薄片等资料获得精准的裂缝参数分布,并将断层距离与裂缝发育强度建立关系; 以裂缝发育概率体作为趋势约束,通过地质统计学方法建立了裂缝模型。结果表明,研究区主要发育微裂缝,裂缝的分布与断层的发育密切相关,裂缝属性高值主要分布在断层附近。建立的双重介质三维地质模型定量描述了基质和裂缝的分布特征,为油藏数值模拟打下了良好基础,为制定合理的开发方案提供指导。
Abstract:
Taken a carbonate reservoir of M Oilfield in Iraq as an example, the percolation capacity of the reservoir has been improved greatly by the development of fracture, and it is necessary to establish an accurate dual-medium model reflecting the overall seepage characteristics. On the basis of fine stratigraphic framework, a matrix property modeling with facies-controlled was carried out under the method of data analysis and optimization. According to core observation, imaging logging and microscopic slice data, the accurate distribution of fracture parameter was obtained. Meanwhile, it was established the relationship between fault distance and fracture development intensity. Taken the fracture development probability as a constraint, the fracture model was established by the geostatistical method. The results showed that microfractures are mainly developed in the study area, and the distribution of fractures is closely related to the development of faults. Meanwhile the high value of fracture property is mainly distributed near faults. The distribution characteristics of matrix and fractures were quantitatively described by the 3D geological model of dual-media. So this lays a good foundation for reservoir numerical simulation, and provides guidance for making reasonable development plan.
