Flow Simulation and Influence Factors Analysis of CO2 Foam Fracturing in Annulus Injection
CO2 foam fracturing fluid is widely used in unconventional oil and gas production because of its easy flowback and low damage to the reservoir. Nowadays, the fracturing process of CO2 foam fracturing fluid injected by coiled tubing is widely used. However, the small diameter of coiled tubing will ca...
