为减少气田水对环境的影响,确保气田合理开发,目前对气田水最有效的处理方式是异层回注处理,但对不同气藏的气田水进行回注时,要保证回注成功和回注系统正常运行,必须进行配伍性实验。针对川中地区须家河组、嘉二段和长兴组气田水的水质特征,与回注层大安寨段地层水及岩心进行了配伍性实验,从而了解影响回注的因素,并提出相应的解决措施。在岩心伤害实验的基础上,推荐了气田地层水回注的水质指标。 |

Abstract: |
To reduce the influence of gas field water to environment,ensuring the reasonable exploration to gas field,the most effective processing mode to it is heterostrate recycling process.For ensuring the success of recycling and the normal movement of recycling system,we should carry on the matching experiments.Aiming at the water quality characteristics of Xujiahe group,Jia’er section as well as Changxing group in the middle of Sichuan,we proceed the matching experiments with formation water and drilling cores of recycling layer Da’anzhai section,thereby recognized the influential factors of recycling,and put forward some corresponding solutions.On the basis of drilling core damage experiments,this article recommends the water quality index on gas field formation water recycling. |
