摘　　要：回顾了地层测试与井下流体分析技术领域的发展过程;以光学流体分析、声学流体分析、核磁共振流体分析等井下流体分析技术以及聚焦取样、低冲击取样等低污染取样技术为例,对取得突破性进展的关键技术进行了分析和总结;认为目前该项技术研究重点正转向随钻地层压力测试与流体分析取样,所要面对的挑战主要来自于钻铤的强冲击振动、钻柱的巨大扭力、井下流体静压力、钻屑磨蚀及高温高压等恶劣钻井环境条件。提出了相应的研发策略建议。Technologies of formation testing and fluid sampling have made considerable progresses in recent years, more and more new techniques and apparatuses are being developed. This paper reviews the developing processes and the fundamental changes in this field. It investigates key technologies based on case studies of downhole fluid identification using optical, acoustic and magnetic resonance techniques, and of low level contamination sampling with focused sampling and ＂low shock＂ sampling techniques. It is considered that the research focus in this field is turning to the formation testing and sampling while drilling with challenges from harsh drilling environments including high level shocks and vibrations of drill collars, great torques of drill string, huge static pressure of downhole fluid, severe abrasion of cuttings, and high pressure and high temperature. Some suggestions are given for their research and development.
