前言冶金部地质局组织的国外钻探工程服务队(50人),1983年3～9月与日本灌浆公司配合,赴伊拉克承包贝肯水坝基地的地质工程钻探任务.开动钻机11台(每台3人操作),实行每月26天、每天单班12小时工作制(8小时钻进,4小时透水试验),共钻进66个钻孔,完成工程量6970米,平均台月效502米,岩芯采取率95.3%,进行透水试验1179次(成功率达98%),钻孔合格率100%,人造金刚石钻头平均寿命141米,最高600米,提前3个月完成了计划任务.
Foreword Foreign drilling engineering service team (50 persons) organized by Metallurgical and Geological Bureau cooperated with Japanese grouting company from March to September 1983 to go to Iraq for contracting the drilling of geological engineering of Beken dam base, starting 11 drilling rigs Person operation), the implementation of 26 days a month, a single shift 12 hours a day (8 hours drilling, 4 hours water permeability test), a total of 66 drilling holes to complete the project volume of 6970 meters, 502 meters average monthly efficiency, Core take rate of 95.3%, water permeability test of 1179 times (success rate of 98%), drilling pass rate of 100%, synthetic diamond drill life expectancy of 141 meters, up to 600 meters, completed the planning 3 months ahead of schedule.
