摘　　要：本文在假定气水混合介质处于环状流的前提下,建立潜孔冲击器在湿式凿岩中的性能仿真程序。运用这一程序对J-170B型冲击器进行了仿真计算,并作了实验性检验。此外,还对逆止阀式气水分离器进行了设计与实验研究。A emulator program for the performances of down-hole hammer in wet drilling is established with hypothesis that the gas-water mixture medium is in circular flow, and used to perform emulation calculations for J-170B hammer and experimentally examined Additionally, a gas-water separator in check ralve pattern is designed and investigated.
