摘　　要：碳酸盐岩油田的产能受多种因素影响,如何准确评价油田产能,并对单井进行配产是碳酸盐岩油田开发的关键任务。以IMA油田为例,结合油田地质和动态研究,提出了对油田产能进行综合评价的方法,即根据油田的裂缝、沉积相和含水特征,将油田在平面上划分了4个区域3个等级,然后分别配产。利用油田新投产的2口油井进行验证,结果表明利用产能综合评价方法计算的配产值和油井实际产量是比较匹配的。该方法对碳酸盐岩油藏产能评价有重要的借鉴意义。The productivity of carbonate reservoirs was influenced by many factors.How to accurately evaluate oilfield productivity and carry out production allocation of single wells were the key tasks for carbonate reservoir development.By taking IMA Oilfield for example and combined with geological and dynamic researches of the oilfield,a comprehensive productivity evaluation method was presented.Namely,according to the characteristics of fractures,sedimentary facies and water content,the oilfield was divided into four regions at three grades in the plane and production allocation was carried out respectively for different regions.Two new production wells are used for approval,the results show that the production allocation value calculated by comprehensive productivity evaluation method is well matched with actual production.This method provides important reference for productivity evaluation of carbonate reservoirs.
