摘　　要：在中高渗油藏的水驱开发过程中,由于水流的长期冲刷作用,储层岩石的部分颗粒发生运移,伴随着油井出砂储层大孔道逐渐发育,边底水或注入水无效循环严重,影响油藏的开发效果。以高浅北区G104-5区块高渗透稠油油藏为例,基于现场油水井生产特征优选了10个评价大孔道发育程度的动静态指标参数,应用层次分析法确定指标权重;综合考虑油水井22种生产动态调整措施对大孔道评价的影响,基于模糊综合评判原理建立了一套大孔道动态评价方法,利用VBA编程进行计算;利用吸水和产液剖面测试数据对大孔道动态评价法进行了验证;计算大孔道评价指数,应用Petrel软件绘制大孔道随时间变化的分布图。研究成果对于认识中高渗稠油油藏大孔道时空演化规律具有重要的指导意义。During water flooding in medium-high permeability reservoir,due to the long-term scouring effect of water flow,some particles of reservoir rocks are transported.Along with the gradual development of high capacity channel of oil well sand production,ineffective circulation of edge and bottom water and injected water has become significant,and hampers the efficiency of reservoirs.We investigated the high-permeability heavy oil reservoir in block G104-5 of Gaoqianbei district.10 dynamic and static index parameters were optimized based on the production characteristics of well site oil and water wells,and the index weight was determined with the Analytic Hierarchy Process(AHP).Considering the influence of 22 types of production dynamic adjustment measures of oil and water wells on the evaluation of high capacity channel,a set of high capacity channel dynamic evaluation method was established based on the fuzzy comprehensive evaluation principle,and VBA programming was used for calculation.The high capacity channel dynamic evaluation method was verified with the test data of injection profile and liquid producing profile.Evaluation index of high capacity channel was calculated,and the distribution map of high capacity channel with time was drawn by using the Petrel software.Our results provide an important guidance for understanding the spatial-temporal evolution law of high-capacity channel in medium-high permeability heavy oil reservoirs.
