摘　　要：已发现油气田储量增长评价是油气资源潜力评价的主要研究内容,评价对象所处区域的地质和开发条件不同,储量增长预测模型也各不相同。采用修正Arrington方法,分析了扎格罗斯盆地已发现油田可采储量随着油田年龄增长的变化规律,建立了可采储量累积增长系数和油田年龄的数学模型,预测了盆地已发现油田储量增长的潜力。同时分别研究了不同储量规模、不同发现年代油田对储量增长的贡献。研究表明:扎格罗斯盆地储量增长模型符合幂函数形式,已发现油田在未来30年可采储量将增长20.7%。随着盆地勘探开发的进程,储量增长速度呈不稳定的阶梯状,其中可采储量规模大于150 MMb的油田储量正增长的潜力较大;在相同时间段内,已发现油田的储量增长速度远远大于新油田的发现。Reserve growth assessment of known oil fields is an important task in resources evaluation. The reserve growth forecast models differ from region to region due to different geological and development conditions. By using modified Arrington method, this paper analyzed the recoverable reserve variation with oilfield age, established a mathematical model between cumulative growth factor and oilfield age and forecasted the potential reserve growth in the future. Meanwhile, we studied the actual reserve growth of oilfields with different reserve scales and discovery periods. Results show that the reserve growth model of Zagros Basin follows a power function. The recoverable reserves of the known oilfields in Zagros Basin will increase 20. 7 % in the next 30 years. The reserve growth rate of Zagros Basin is unstable and stepped in the exploration and development process. Oilfields with recoverable reserves larger than 150 MMb in this region have greater positive growth potential and reserve growth rates of the known oilfields are much larger than that of the newly discovered oilfields in the same period.
