摘　　要：可采储量增长被用来评价已发现油气田可采储量的增加潜力,是剩余石油和天然气资源的一个重要组成部分。通过对哈法亚油田可采储量增长影响因素和潜力的分析,发现其影响因素包括地质因素、工程因素和经济因素。哈法亚油田2010年至2012年的可采储量增长主要是由发现新油藏、已发现油藏地质储量增加和采收率提高组成,对可采储量增长的贡献分别为7%、51%和42%;未来通过油田扩边可以增加约7 956.5×104t的石油可采储量。通过与Majnoon油田进行类比分析,认为未来哈法亚油田采收率可以达到32%,储量增长潜力约0.98×108t.Reserve growth that is used to evaluate the incremental potential of recoverable reserves in discovered oil-gas fields is a major component of remaining oil and natural gas resources. According to the study of the influencing factors and growth potential of reserve growth in Halfayah oil field, it is found that the factors include geological factor, engineering factor and economic factor. The reserve growth of Halfayah oilfield in 2010-2012 is composed of the discovery of new pool （contributing 7%）, the incremental OOIP （51%） and the incremental EOR （42%） in discovered reservoirs. And the extension of the field in the future could allow the reserve growth to be added about 7 956.5×10^4 t. According to the analogy analysis with Majnoon oilfield, it is believed that the recovery factor of Halfayah field will reach to 32%, and the reserve growth potential will add about 0.98× 10^8 t.
