摘要: 油田开发进入高含水期,储层的非均质性和储层的敏感性导致孔喉增大,注入水沿着高渗透带形成窜流通道,严重地影响了开发效果。根据储层参数、微观孔隙结构的变化,阐述了综合分析窜流通道的定性方法。引入大孔道综合指数的概念,应用模糊综合评判的方法,定量识别了窜流通道的分布规律。

Abstract: During high water cut period of oil reservoir,pore throats of reservoirs become larger and the injected water is easy to form channeling-path along the high-permeable area,because of reservoir heterogeneity and sensibility.Those situations have serious effect on oilfield development.On the basis of the change features of reservoir parameters and pores microstructure,a quantitative description method for channeling-path was discussed.The distribution rules of channeling-path were quantitatively identified by introducing the big-pore channel comprehensive exponent and by applying fuzzy comprehensive analysis.

Key words: oilfield with high water cut, reservoir heterogeneity, injected water, channeling-path, distribution rule, quantitative description, fuzzy analysis
