Abstract: |
In order to enhance the recovery of coal bed gas,it was studied the viscoelastic surfactant-based CO2-compatible fracturing fluid. The sample of coal came from Fuxin in Liaoning province. We mainly researched the factors which influence this foam system’s stability,and appraised this foam system according to the water-based fluid’s standard. We had got a compatible fracturing system with fine performance. |
Key words: CO2-based compatible VES coalbed gas fracturing fluid performance |
