摘要
岩石分类是碳酸盐岩油藏描述和为油藏模拟建立地质模型必须考虑的步骤。应用取心井岩心样品的孔隙度、渗透率和毛管压力数据,采用Winland R35方法划分了国外某碳酸盐岩油藏的岩石类型。实验结果和计算结果对比表明,WinlandR35方法预测的孔喉大小较为合理,采用该方法划分的岩石类型相渗曲线和毛管压力曲线具有相似性。研究结果可以应用于建立基于岩石类型控制的三维地质模型。
Rock typing is an essential step in carbonate reservoir characterization and geological model building for reservoir simulation. Porosity, permeability and capillary pressure data of coring core samples are used by Win- land R35 method to divided rock types of an abroad carbonate oilfield. The experimental results and the calculation results show that the throat size predicted by Winland R35 method is reasonable, each rock type classified by this method have similar relative permeability curves and capillary pressure curves. The research results can be applied to establish three-dimensional geological model.
