摘要: 中高含水期砂岩油藏在长期注水中容易形成大孔道,造成注入水无效循环,影响开发效果,降低了油藏采收率.该文以红岗油田高台子油藏为例,综合考虑影响储层大孔道形成因素,选取孔隙度、渗透率和含水率变化率等多种静态和动态指标,利用层次分析法确定各个指标的权重后计算出大孔道综合指数.并以此为建模参数,采用相控随机建模的方法建立了研究区储层大孔道三维模型,定量表征储层大孔道分布和发育情况,为油田后续的注采方案调整提供了地质依据.通过选取影响大孔道形成的静、动态指标确定大孔道综合指数,然后建立大孔道模型的方法,为储层大孔道研究提供了一个新的方向,对同类油藏大孔道研究具有借鉴意义.Abstract: In sandstone reservoirs which were during the medium and high water cut stages,high-capacity channels might take place after long terms of water flooding,which made the circulation of water flooding very inefficient,and further reduced exploration efficiency and recovery rate.A case study was carried out in the Gaotaizi Reservoir of the Honggang Oil Field.The influencing factors for the generation of high-capacity channels were studied.Porosity,permeability and water content ratio were chosen as static or dynamic indexes to calculate high-capacity channel parameter by confirming the weight of each index.Based on the above-mentioned modeling indexes,a three-dimensional model for high-capacity channels in the study area was set up so as to illustrate the generation and distribution of high-capacity channels in reservoir and to provide geologic basis for future oilfield development.This new method provided direction for the research on large pores,and was significant for the study of other similar reservoirs.
