摘要(Abstract)：

升深A区块是目前大庆长垣地区动态储量最高、稳产能力最强、单井产气量最大的气田,但底水作用强、CO_2含量高,开发风险较大,必须落实好气井合理配产,达到科学高效开发要求。从升深A区块气藏试采动态特征入手,运用指示曲线、最小携液流量、底水气藏临界产量、气液对管壁的冲蚀作用等气藏工程理论计算了气井的合理生产区间,并建立了合理产量确定模型。通过几年来的有效实施,区块气井展现出地层压力稳定、年产气量稳定、水气比稳定的良好开发态势。
Block Shengshen A is the gas field that has the highest dynamic reserves,the strongest stable production capacity and the biggest gas production rate per well in Daqing Placanticline at present. But it is necessary to determine the reasonable production rates of the gas well for the scientific and high-efficiency developments because of its strong water drive,high-content CO_2 and so on. Beginning from the dynamic characteristics of the production test of the gas reservoir in Block Shengshen A,the reasonable production rate ranges of the gas well were calculated with the help of the index curves,minimal liquid carrying flow rate,critical production rate of the bottom water gas reservoir,washing action of the gas and liquid to the string wall and so forth,and moreover the model of the reasonable production was determined as well. For several years of effective operation,much more stable and better development situation has shown for the gas well in the block in the formation pressure,annual gas production rate and water-gas ratio.
