摘要
针对渤海某凝析气田气井因高含水而停产的情况,基于对高含水井的产水氯根含量、邻井生产动态特征及储层裂缝等方面的研究,对气井的产水来源及水侵通道进行了分析,结果表明产出水为凝析水和地层水的混合水,地层水沿太古宇储层裂缝上侵,导致含水突升。根据气井的潜力分析、系统测试、关井前产量及邻井目前产量等方面的资料,提出了复产的措施建议及指标预测,为凝析气田后期的开发调整提供了一定的参考。
For gas wells of a Bohai condensate field stopping production due to high water-cut,based on the research of chloride content of high water-cut wells,dynamic characteristics of adjacent wells,formation fracture and so on,the produced water source and water invasion channel for gas wells were analyzed and results showed that the output water was mixture of condensate water and formation water.Formation water invaded along the Archean formation fracture and led to water-cut jump.According to gas wells potential analysis,system testing,production before the shut-in,adjacent wells production and so on,the measures suggestion and index prediction for restoring production were put forward and provided a certain reference for development adjustment of condensate field later stage.
