阐述超临界CO2流体物理特性,分析超临界CO2射流在喷射钻井、喷射压裂、驱油提采、冲砂解堵和油套管除垢等作业中的原理和技术优势,探讨超临界CO2开发非常规油气藏的可行性,展望超临界CO2射流在石油工程中的应用前景。
The physical properties of supercritical CO2 fluid was explained firstly. Then the principle and predominance of supercritical CO2 jet 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 CO2 fluid in devel- oping unconventional oil and gas reservoir was also discussed and the outlook of supercritical CO2 jet application to petroleum engineering was viewed.
