摘　　要：液动射流式冲击器在实验室中进行深井模拟试验,其可行性在实际应用中得到了验证。但同时出现一些问题,解决的办法之一就是增大喷嘴宽度。为此进行了模拟试验,结果表明喷嘴宽度在一定的条件下对射流切换有影响。Hydro-jet impacter is used to make deep well simulation test in lab, its feasibility is confirmed in practical application. Meanwhile, some problems occur, one of resolvent is to add nozzle width. So simulation test is made and result shows that nozzle width could affect jet switching performance under certain conditions.
