摘　　要：注水开发的砂岩油藏中发育的优势渗流通道对于开发效果具有很大影响。优势通道的作用主要表现为注水低效循环,降低波及系数。提出一种改进的CRM模型,用生产动态数据来识别井间优势渗流通道。与其他方法相比,该方法具有成本低、识别结果准确的优点。将该方法用于实际油藏中,结果表明该方法的识别结果与其他测试方法如示踪剂和吸水剖面的测试结果一致,说明该方法具有较强的可靠性。Predominant seepage channels developed in waterflooding sandstone reservoirs has a great influence on the development effect.Their effects are mainly presented as inefficient water injection cycles and reducing sweep coefficient.In this study,an improved CRM model was proposed to identify high permeability channels based on production performance data.Compared with other methods,this method has the advantages of low cost and high accuracy.This method was used in actual reservoirs,and the results showed that the results of this model are consistent with those of other methods such as tracer and water absorption profiles,indicating that this method has strong reliability.
