我院以李大佛同志为首的电镀钻头研究室研制的8(1/2)时电镀金刚石石油钻头初试成功(注:1时=25.4毫米)电镀金刚石石油钻头是在该研究室获得国家发明三等奖和地矿部科技成果一等奖以后又一新产品.电镀金刚石石油钻头于今年二月在大庆油田X号并投入生产试验,钻头从孔深3411.68米下井试验,在九级泥岩中进尺5.31米,纯钻进时间是7小时零5分,时效为每小时0.74米,取得了较好的成绩,获得了大庆油田钻井X公司总工程师的好评.
In our hospital, the experiment of electroplating drill head led by Comrade Li Da-fu was successful in the first trial of electroplating diamond oil drill bit (Note: 1 = 25.4 mm) when electroplating diamond drill bit was 8 (1/2) Award and the first prize of the Ministry of Geology and Minerals Scientific and Technological Achievements after a new product.Electroplated diamond oil drill in February this year in Daqing Oil Field X and put into production test, drilling down hole 3411.68 meters downhole test, into the nine mudstone footage 5.31 Meters, pure drilling time is 7 hours and 5 minutes, aging 0.74 meters per hour, and achieved good results, won the Daqing Oilfield Drilling X chief engineer of praise.
