| 摘 要： | 通过类比相关喷反机具设计,设计并制造了某型喷反装置模型。之后进行了结构优化实验研究,得到了一系列适于现场工况的喷反装置关键器件优化组合,并认识到该类喷反装置中,喉管喷嘴组合模式对吸水效率的影响最大,而流量参数m、间距S对吸水效率的影响较小;喷嘴喷速大于40 m/s时,其吸水效率急剧下降。

| Abstract: | On the analogy of relevant design, a preliminary design and experimental prototype of jet-type reverse circulation tool was completed, which could be used for horizontal hole. Based on structural optimization experiments and researches, a series of optimized combinations of key components were derived, which were appropriate to in-situ conditions. According to experiment results, some conclusions were drawn as follows: the water absorption rate was most influenced by the mode composed of jet tube and jet nozzle and little influenced by flow parameter m and span S; and when the jetting rate exceeded 40m/s, the water absorption rate decreased sharply. |
