[本刊讯]不久前,中国地质调查局勘探技术研究所研制的Φ147mm规格外加厚铝合金钻杆在“松科二井”工程中应用成功,标志着地调局勘探所研制的铝合金钻杆已初步形成系列化。2015年5月16~25日,Φ147mm铝合金钻杆(钻具组合采用钢、铝复合钻柱)在“松科2井”共下井8个回次,采用Φ311mm口径取心钻进累计进尺93.89m,井深3059.87m,取得了较好的技术应用效果。本次生产试验是我国自主开发的科学深井铝合金钻杆的首次应用,试验将持续进行,在考核国产 Not long ago, the China Geological Survey Exploration and Production Technology Institute developed Φ147mm specifications thick aluminum alloy drill pipe in the “Songke Second Well” project in the successful application of the Geological Survey Bureau of exploration developed by the aluminum alloy Drill pipe has been initially formed series. From May 16 to May 25, 2015, the Φ147mm aluminum alloy drill pipe (with a combination of steel and aluminum composite drill string) was drilled 8 times in “Songke 2” and coringled with Φ311mm caliber Footage 93.89m, well depth 3059.87m, made a better technical application results. The production test is our first application of scientific deep-hole aluminum alloy drill pipe, the test will be continued in the assessment of domestic
