摘　　要：以中东地区大油田为研究对象,对不同时期估算的新增可采储量进行对比,分析其储量增长特征;通过统计油田的年储量增长系数,采用最小二乘法建立年储量增长函数,对中东地区已发现大油田的储量增长潜力进行了预测。新增可采储量由两部分组成:新发现储量和已发现油气田的储量增长。研究发现,中东地区过去几十年已发现大油田的储量增长有较大幅度的增加,而新发现储量有所减少。已发现大油田的储量增长为新增可采储量的主要贡献者,占新增可采储量的比例从1981—1990年的71%增加到2001—2010年的96%。根据建立的储量增长函数,估算中东地区已发现大油田未来石油储量增长约为4 366×108 t,储量增长潜力巨大。Giant oilfields in the Middle East were taken to analyze the characteristics of reserve growth by comparing the estimated additions of recoverable reserves during different periods. The reserve growth potential of the discovered giant oil fields in the Middle East was predicted through statistics of annual reserve growth factors and building annual reserve-growth fimction by the least square method. The additions of recoverable reserves are comprised of reserves in newly discovered oilfields and incremental reserves of the giant oil fields discovered previously. The study shows that the incremental reserves in the giant oilfields discovered previously have increased sharply, but the reserves in newly discovered oilfields have decreased slightly over the past several decades. The incremental reserves in the giant oilfields discovered previously are the major contributor to the newly increased recoverable reserves, and their proportion increased from 71% in the 1980 s to 96% in the 2000 s. According to the established fi.mction of reserve growth, it is estimated that there will be about 4 366~ 108 tons of reserve growth in the giant oil fields discovered previously in the Middle East, suggesting great potential of reserve growth.
