平湖凝析气藏放一断块产水动态特征研究

针对平湖凝析气藏气井出水问题，依据气井动态测试资料，将出水气井划分为明确出水层位和不明确出水层位两类气井，分别分析了其出水机理和产水动态规律:明确出水层位气井的产出水来自其他断块的水层，其带水生产能力与产水气层的产气比例具有良好的相关关系，出水气层的产气比例越小，气井的带水生产能力越高，反之则带水生产能力越低；不明确出水层位气井的产出水是异常高温高压边水凝析气藏的地层水在生产过程中转成水蒸气后的凝析水。随着开发的进行在边水水体与生产井之间形成3个不同的凝析水饱和流动区，根据凝析气藏地层水气化饱和模式和饱和凝析水生产水气比与压力关系曲线，可以进行气井产水类型的判断和地层水出水风险的预报。 

Study on Water Production Dynamic Performance of F1 Fault Block in Pinghu Gas Condensate Reservoir

For the problem of water production in Pinghu gas condensate reservoir,gas wells are divided into wells with identified and unidentified water producing formation based on gas well dynamic testing data.Water production mechanism and performance are analyzed.The result shows that the gas well water production comes from other blocks.Water production capacity has good correlation with the gas ratio in gas formation with water production.The smaller the gas ratio,the higher the water production capacity and vi...
