为了解决应用S75钻杆在深部钻探中易出孔内事故,钻工劳动强度大的问题,本单位与福建省地质八队地勘公司合作,研制出SJ75深部钻探用钻杆,取得了良好效果。介绍了SJ75钻杆的研制与结构特点及实际应用效果等。
In order to solve the problem that the S75 drill pipe is easy to get out of the hole in deep drilling and the labor intensity of drilling is high, the unit cooperated with the geological survey company of the eight geological teams in Fujian Province to develop the SJ75 deep drilling drill rod and achieved good results . The development and structural characteristics of SJ75 drill pipe and its practical application effects are introduced.
