摘要
在伊朗卡尔赫水电站坝址工程勘察中，采用金刚石双管单动钻具和ＳＭ胶冲洗液进行取样钻探，用清水钻进压水试验，由于钻探工艺合理，钻探质量均达到了设计要求。
Double tube type diamond drilling tools and SM gum flush sluid are used for sampling and clear water is used to undertake water pressing experimant in dam sit surveying at Hydro-electric Station, Iran. Be- cause of reasonble drilling technique,drilling quality reached the designed reached the designed requirement.
