摘要
建立低渗透砂岩油藏储集层模型以建立裂缝系统的数值模拟模型为重点。针对低渗透砂岩油藏储集层双孔双渗的特点,在前人研究成果的基础上,利用现有的裂缝描述技术,提出了裂缝系统模型中形状因子、裂缝渗透率、裂缝孔隙度的计算及基质系统储集层模型的建立方法。在东营凹陷大芦湖油田樊12井区低渗透砂岩油藏数值模拟研究中,用该方法建立了储集层模型,用其计算的综合含水率与开发时间关系曲线接近油藏实际开发动态数据,减少了历史拟合的工作量。
The modeling of fracture system is the key of modeling a low permeability sandstone reservoir. Considering the characters of the dual-porosity and dual-permeability for lowpermeability sandstone reservoir, based on previous research results, a method for calculating the shape factor, fracture permeability, fracture porosity and the properties of matrix system is presented according to the current fracture descriptive technology. The method is used in the reservoir numerical simulation research on Fan 12 Block, Daluhu Oilfield, Dongying Sag. The calculated water cut trend fits with the actual development data and the workload of history matching is reduced.
