Abstract: |
The physical properties of supercritical CO2fluid was explained firstly. Then the principle and predominance of supercritical CO2jet application to jet drilling, jet fracturing, oil displacement and enhanced recovery, sand plug removing, as well as scale removing in drill pipe and casing operations were analyzed. The feasibility of supercritical CO2fluid in developing unconventional oil and gas reservoir was also discussed and the outlook of supercritical CO2jet application to petroleum engineering was viewed. |
Key words: supercritical CO2 water jet drilling hydraulic fracturing unconventional oil and gas application prospect |
