  • CO2 generates in the course of acidizing treatment with the reaction of acid and rock, which will influence the mechanism of acid leaking. An acid filtration model considering CO2 effect has been set up based on the conventional acid filtration model in order to study the CO2 effect on acid liquid loss and to determine the volume of free CO2. Simulation results showed that the volume of free CO2 increases with increasing acid concentration and decreases with increasing pressure. In acid corrosion fractures, when free CO2 exists, filtration law is the same as foam fracturing, and the volume of acid fluid loss reduces with increasing CO2 volume.
