摘　　要：在开展水平孔某型喷反装置实验研究及测试中发现,吸水效率η这单一因素不能全面、正确地评判或比较其喷反装置的性能。针对喷反效能的评判问题开展了分析与讨论,并应用功率转换因素k值进行喷反效能评判实例分析,提出了用系统压力、吸水效率及功率转换系数综合衡量喷反装置效能的评估观点。Based on the experiment and research results of jet-type reverse circulation tool in horizontal hole, preliminary analyses and discussions on the efficiency evaluation of this tool have been carried out. As a result, a viewpoint of efficiency evaluation using system pressure, water absorption rate and power conversion factor for synthetic weighting was introduced.
