摘要: 介紹了寶山鋼鐵股份有限公司鉆桿技術(shù)的最新發(fā)展。從理論研究方面,敘述了鉆桿加厚過渡區(qū)失效分析與有限元分析的研究成果。在質(zhì)量的持續(xù)改進(jìn)方面,介紹了材質(zhì)的純凈度、韌性、內(nèi)加厚過渡區(qū)Miu長度、直度等鉆桿關(guān)鍵技術(shù)指標(biāo)的改進(jìn)情況。在新產(chǎn)品開發(fā)方面,介紹了BGDS高抗扭鉆桿、NC52非標(biāo)鉆桿、抗硫鉆桿等新產(chǎn)品的開發(fā)與使用情況。

Abstract: The paper deals with the latest development of the drill pipe technology in Baosteel. Elaborated are the research achievements concerning failure analysis and FE analysis of the drill pipe upset transitional section from the theoretic research point of view. Also described is the continual improvement of the product quality, involving improvements on the critical technical indexes of the drill pipe,including cleanness and toughness of the material,Miu length of the internally-upset transitional section and the straightness,etc. Moreover,new product development is introduced, covering the development and application of some new products like the BGDS high torque drill pipe,the NC52 non-standard drill pipe and the sour service drill pipe.
