2由于TSR产生的大量淡水的加入，使气藏的原生地层水被稀释，造成地层水盐度降低；

A great deal of water produced by TSR makes the original formation water in the gas reservoir diluted , so that the salinity of formation water is reduced correspondingly ;

我国大部分油田地层水属弱碱性，HPAM溶液在这类污水中的水解反应速度很快，稳定性变差，因此在选择聚合物和水质时，应充分考虑高温水解作用的影响。

The most formation waters in our country belong to weak alkaline , HPAM will hydrolyze rapidly in this type of water , and the thermal stability and viscosity of HPAM solution will decrease obviously .
