本文作者是应联邦德国克劳斯塔尔大学深井研究所的邀请前去西德访问的。参观了设在Oberpfalz的超深孔钻探计划的导孔钻探现场,ITAG公司承包的高压气田钻探现场,还考察、参观了四个大型钻探工具厂。本文对钻探现场和钻探工具厂都作了介绍。本文最后着重介绍了克劳斯塔尔大学深井研究所为我国地矿部举办的钻探研讨会。研讨会的交流重点是金刚石钻头制造工艺学,液动冲击回转钻探、小口径受控定向钻探及钻井液的新进展等。我国五位代表在研讨会上都宣读了论文。
The author is going to visit Germany at the invitation of the Institute for Deep Wells of the University of Clausthal in Germany. Visited the pilot hole drilling site of the ultra-deep hole drilling program in Oberpfalz, ITAG contracted high-pressure gas field drilling site, and also visited and visited four large drilling tool factories. This article describes both the drilling site and the drilling tool factory. At the end of this paper, we focus on the drilling seminar held by the Deep Well Research Institute of University of Claustrens for the Ministry of Geology and Mineral Resources of China. The focus of the symposium was the diamond bit manufacturing technology, hydraulic impact rotary drilling, small-bore controlled directional drilling and drilling fluid new developments. All five representatives of our country read out the papers at the seminar.
