摘　　要：在深井和硬地层钻井中 ,地质构造复杂、地层倾角大、地层研磨性强 ,机械钻速低、钻具失效严重 ,钻柱设计是其中的制约因素之一。为此 ,文章提出以钻柱的强度和沿程水力损失为依据 ,对深井、强化钻井钻柱设计进行了探讨。针对 12 7mm钻杆在深井、强化钻井的不足 ,提出采用 139.7mm或 14 9.2mm钻杆 ;对深井尾管段小井眼 ,针对 88.9mm钻柱的不足 ,提出采用 10 2mm钻杆。同时 ,以钻杆材料的力学性能为例 ,指出在正确认识API标准的基础上 ,制定高于API标准的企业标准势在必行。In the process of drilling deep well and hard formations, the drill string design is one of the factors restricting low ROP and serious BHA failure. The drill string designs of deep well and forced drilling are discussed in the paper according to the strengths of drill string and the hydraulic losses of mud circulating. In the paper, in light of the shortcomings of the Ø 127 mm drillpipe in deep well drilling and forced drilling, it is proposed that the Ø 139.7 mm or Ø 149.2 mm drill pipe should be applied: and in consideration of the disadvantages of the Ø 88.9 mm drillpipe in drilling the slim hole of the liner interval of deep well, it is put forward that the Ø 102 mm drillpipe must be utilized. Meanwhile, by taking the mechanical property of drillpipe material as an example, this paper points out that it is imperative to draw up an enterprise standard which is higher than API standard, on the basis of recognizing correctly the API standard.
