摘　　要：大庆油田已探明气田21个,按现行的有关规范多数为小型低产、低丰度气田,不利于进行气藏资源潜力评价。在充分调研的基础上,建立了适合大庆油田气藏实际特点的分类评价标准。根据该标准,通过对已探明气田地质特征、开发特点的综合研究,把21个气田(藏)划分为九大类,对各气田的储量进行了风险评估,利用模糊优化方法对各气田的开采次序进行了优选。So far,there are 21 gas reservoirs in Daqing oilfield. According to the existing criteria,most of them are small- scale and low- abundance gas reservoir,which are unconvenient to evaluate their potentials.This paper,based on sufficient research,establishes the classification and evaluation certeria that are fit for the practical features of the gas reservoirs in Daqing oilfield.On the basis of the above certeria,the 21 gas reservors are divided into nine types according to the geological characteristics and development features of the explored gas reservoirs.Risk assessment for the reserve of each gas field is performed.The development sequence is optimized by fuzzy optimization.
