| 中文摘要: |
| 绳索取心钻杆在深孔钻探中占重要的地位。本文分析了目前国内钻杆在深孔钻探中的使用情况，同时还对钻杆柱的失效及绳索取心钻杆在钻井内的受力情况进行了简要的分析。设计出了两种复合钻杆：一种是塔式复合钻杆，另一种是同径复合钻杆。将其应用在“中国岩金勘查第一深钻”山东莱州三山岛矿区ZK96-5孔4000m钻孔中，取得了良好的效果。 |
| 英文摘要: |
| Wire-line coring drill pipes have played a very important role in deep well drilling. This paper analyses briefly the drill pipe failures and forced state of wire-line coring drill pipes in boreholes as well as the usage situation of domestic drill pipes in deep drilling. Two types of composite drill pipes were designed, one is the tower-type composite drill pipe, and the other is the iso-diameter composite drill pipe. Both of these two types of drill pipes have been applied to the 4000m-deep ZK96-5 drilling hole, named the “First deep drilling hole in rock gold exploration in China”, in the Sanshan Island mine area, Laizhou, Shandong, yielding good results. |
