适合煤层气储层的滑溜水压裂液体系研究
Research of Multifunctional Slickwater Fracturing Fluid System Suitable for Coalbed Methane Reservoirs
摘要
Abstract
The authors used a bifunctional reducing agent containing degradable groups and oxidized metal ions as a redox agent to initiate free radical polymerization and synthesize a polymer damper to build degradable groups on the vinyl polymer backbone.The results showed that the azo groups were degradable under high temperature and also had high hydrolytic stability.The degradation behavior of polymeric drag reducers containing temperature-sensitive azo groups was characterized by gel permeation chromatography(GPC),which demonstrated that the polymer backbone contained multiple unstable bonds.It was also found that the drag reducers with azo bonds on the polymer main chain had as good drag reducer properties as the pure drag reducers.However,those with azo bonds in the main chain will lose their damping performance once subjected to high temperatures.This study provides a reference for the selection of low-injury multifunctional slickwater fracturing fluid systems suitable for shale gas reservoirs.关键词
