摘要
近年来,随着酸性气田的勘探开发及特殊钻井工艺的应用,钻具失效事故时有发生,对钻具的安全性能提出了新要求。对国内外的抗硫钻杆、铝合金钻杆、钛合金钻杆等高性能钻杆的性能和特点进行了综合分析和评价,为复杂环境和服役工况下的钻具选用提供参考。针对这些高性能钻杆的性价比,提出了我国自主研发高性能钻杆的建议。
In recent years,with the acid gas field exploration and development and use of special process wells,drilling failure accidents have occurred and put forward new requirements on the safety performance of the proposed drilling.In this paper,performance and features on domestic and international resistance to sulfur drill pipe,aluminum alloy drill pipe,titanium drill pipe and other high-performance drill were comprehensive analyzed and evaluated,which refer the advice on the selection of drill pipe in different service conditions,and put forward the independent research direction on the high-performance drill pipe in China in recent years.
