| 摘 要： | 为治理水驱油藏的水窜现象、提高注水利用率,需要确定出油藏存在窜流的低效注采井区、层位.根据油田开发实践,提出能反映油水井发生水窜的动态特征指标,然后选用适当的数学方法对各类指标进行无量纲化处理,得出反映油藏注采井间窜流状况的评价指标集,利用权重系数法得到评判油藏注采井间窜流严重程度的综合评价指数.通过油田的开发实践总结...

| Abstract: | In order to address the chanelling phenomenon in water-flooding reservoir and improve injection efficiency,the inefficient injection-production well areas and layers in which interporosity flow existes are need to be determined.Based on the oilfield development practises,the dynamic characteristics indices reflecting water channelling are proposed,and various indices are handled dimensionlessly with the selected mathematic method to form a evaluation set which can reflect the channelling condition between i... |
