摘　　要：近年来,随着国内外油气勘探目标进一步向深层、海洋等非常规油气藏推进,所钻遇地质环境愈加复杂,在其钻探过程中发生溢流频率也越来越高,井控安全面临巨大挑战。而作为井控安全的第一道屏障,早期溢流监测技术应用与发展对预防井喷具有重要理论及实践意义。为此,文章通过分析当前井控技术面临难点,从井口监测、井下监测两个层面入手,系统地回顾了国内外早期溢流监测技术研究现状,并阐述了各监测方法的优势及局限性,认为“井下流体实验室”与利用大数据及人工智能的风险诊断模型是当前石油勘探与开发重点应用技术,在早期溢流监测工作中具备很好的应用潜力。最后针对深层、海洋和可燃冰等非常规油气建井早期溢流监测所面临的困难,在现有溢流监测技术的基础上,提出了相应对策与发展趋势,以供同行业者参考。In recent years,with oil and gas exploration destination at home and abroad further advancing to the deep,marine and other unconventional oil and gas reservoirs,drilling geological environment is more complex,the frequency of kick is increasing during drilling,well control technology is facing great challenges.While as the first barrier of well control safety,the application and development of early kick detection technology have important theoretical and practical significance to the prevention of blowout.As a result,this paper analyzes the difficulties of current well control technology,from wellhead detection and downhole detection,the research status of early kick detection technology at home and abroad is reviewed systematically.The advantages and limitations of each detection method are described.It is considered that"downhole fluid laboratory"and kick diagnosis model using big data and artificial intelligence are the key application technologies in petroleum exploration and development,which has good application potential in early kick detection.Finally,aiming at the difficulties of early kick monitoring for the early well construction of unconventional oil-gas wells such as deep,marine and gas hydrates,based on the existing kick detection technology,the corresponding technical countermeasures and development trend of early kick detection are put forward for reference of the same industry.
