摘要
国内外研究表明二氧化碳压裂技术具有很高的技术可行性,二氧化碳压裂比水力压裂更好的优势有:节水环保、易返排、增产幅度大、减轻储层伤害等。然而,该技术在液态二氧化碳压裂增产机理和裂缝延伸模型等方面的研究还存在不足。综合表明,二氧化碳压裂技术可以显著提高油气采收率。
Studies at home and abroad show that carbon dioxide fracturing technology has high technical feasibility.Carbon dioxide fracturing has better advantages than hydraulic fracturing,such as water saving and environmental protection,easy flowback,large stimulation range and reduction of reservoir damage.However,there are still some shortcomings in the study of liquid carbon dioxide fracturing stimulation mechanism and fracture extension model.The results show that carbon dioxide fracturing technology can significantly improve oil and gas recovery.
