摘　　要：借鉴陆上注水开发油田合理油水井数比计算方法,考虑海上油田高速产液条件下实际生产控制条件及平台液处理能力,建立了一种适合于海上油田合理油水井数比计算的新方法。对比已有的多种计算方法,结果表明,考虑产液量的限制对计算结果影响最大,其次是注采不平衡时注采比的影响,流体物性影响相对最小。海上油田合理油水井数比计算方法同时也为海上新油田开发方案设计及在生产油田调整方案设计中经济合理液处理能力的确定打下基础。According to the calculation method of the reasonable proportion of oil and water injection wells of waterflooding in onshore oilfields,and in consideration of the realistic production and injection conditions and liquid treatment capacity on the platform of offshore oilfields,a new calculation method suitable for offshore oilfields was established.The methods were compared with the other available ones.The result shows that limitation of liquid production has significant influence on calculation result,the influence the injection-production ration under unbalanced injection-production condition is the next,the influence of fluid property is relatively small,the studied calculation method provides a base for setting a plan for new offshore oilfields and adjustment scheme for matured oilfields for improving fluid treatment capacity.
