页岩气藏滑溜水压裂用降阻剂性能影响因素研究
Influencing factors of friction reducer in shale slickwater fracturing
摘要
Abstract
Large displacement and large amount of fluid volume fracturing is increasingly be-coming an effective way of shale gas reservoir development .The friction reducer performance is the critical performance of volume fracturing w hich directly determines the success or failure of the volume fracturing .T his paper studied the relationship among “shear velocity ,linear velocity , the Reynolds number ,relative molecular mass ,concentration and water quality”with the friction reducer performance .The results showed that using shear rate similar principle could not effec-tively evaluate friction reducer performance of slickwater .The performance of friction reducing was recommended to be evaluated by the linear velocity and Reynolds similar principle .When the friction reducers had similar structure and consistent effective concentration ,the bigger relative molecular mass ,the friction reducing performance was better .But high relative molecular mass would cause the cut-resistant and dissolving performance poorly .The concentration of friction re-ducer increased ,the friction reducing performance improved ,but when the concentration in-creased to a certain value ,the friction reducing performance increased smaller ;w hen friction re-ducer concentration was lower than a certain value ,the cut-resistant performance was poor .Wa-ter quality had an impact on friction reducer performance ,namely higher the salinity ,better the cationic friction reducer performance .关键词
