Water-based fracturing fluids pollute the environment,waste serious water resources,and even cause liquid phase traps,etc.,and CO2 fracturing fluids can effectively avoid such shortcomings.This paper reviews the basic research progress of three CO2 fracturing fluids,analyzes their application effects in oil and gas fields,points out the challenges they face in the industrial application process,and puts forward relevant suggestions on their future research directions.
