归纳总结了近年来关于微泡钻井液基本特性的研究进展,包括微泡的结构与尺寸、微泡的稳定性、独特的架桥封堵机理以及流变性,以时间为线索综述了国内抗温微泡钻井液体系的优化与现场应用情况,以助于全面地了解、完善和应用微泡钻井液体系。并展望了该技术的未来发展方向,提出抗温160℃以上的微泡钻井液体系仍需要突破,研发制备新型绿色环保、可降解的耐高温表面活性剂与稳泡增粘剂,是进一步提高微泡钻井液体系抗高温的关键。

This paper summarizes the research progress of CGA drilling fluid in recent years from the four aspects of aphrons structure and size,stability,bridging plugging mechanism,rheological property,and reviews the temperature-resistant CGA drilling fluid system with time as a clue.The future development direction of the technology is prospected,so as to comprehensively understand,improve and apply the CGA drilling fluid system.The future development direction of this technology is also prospected.The author proposes that the CGA drilling fluid system with temperature resistance above 160℃still needs to be broken through.The development and preparation of novel green,environment-friendly,degradable high-temperature resistant surfactant and foam stabilizer is the key to further improve the high-temperature resistance of the CGA drilling fluid system.
