摘　　要：在水驱油藏开发中后期调整方案研究中,剩余油分布研究的同时有必要分析油藏的水淹情况和水驱程度,因而提出含水场图和流场强度场图进行直观表征。场图的分析也有助于在调整方案部署研究之前,进行调整潜力的定性评估和挖潜策略确定,以减少数模研究中措施方案的比选和优化工作量。X油田Z油组应用油藏动态场图分析实现调整方案的快速制定,部署调整井5口及其他措施,预测油田累增油58×104m3。将油藏场图的生成、分级划分及潜力分类进行集成和程序化,能够一定程度上实现水驱油藏开发中后期挖潜方案研究智能化和自动化,从而形成油藏动态场图分析技术,对于指导同类油藏开发调整研究具有实际应用价值和前瞻性意义。Research emphasis is focused on remaining oil distribution in adjustment solutions during the middle and later periods of water-drive reservoir,whereas it is necessary to analyze water out behavior and water-flood control degree,so direct evaluation of water-cut field map and flow intensity field map is put forward in this paper.Field map analysis contributes to qualitative evaluation of adjustment potential and tapping strategy determination before adjustment solution study,aiming to reduce workloads of comparing and optimizing feasible operation schemes in numerical simulation process.Field map analysis has been applied in formation Z of X oilfield,rapid determining final adjustment solution was achieved,bringing about incremental cumulative oil production of 58×104m3 with implementing five adjustment wells and some other operations.Integration and programming of generating,grading and potential classification of field maps will be beneficial for intellectualization and automation of devising adjustment solutions,thus forming the basis of dynamic field map analysis method.This method may provide some practical guidance and foresights for similar reservoir development.
