为了使金刚石钻进管材立足于国内，从一九七一年以来，我所管材组配合北京钢厂、鞍钢钢研所对管材进行了研究，通过试制试验，取得了较好的效果，为发展我国金刚石钻进起了一定的促进作用。一、钢管材质性能金刚石钻进用管材包括钻杆（及其接头）、岩心管和套管。小口径金刚石钻进孔径小，钻具与孔壁间隙小，钻进时钻具转速高。要求钻具有良好 In order to make diamond drilling pipe based on the domestic market, our pipe group cooperated with Beijing Steel Plant and the steel research institute of Ansteel made a study on the pipe since 1973, and achieved good results through the trial production test for the development China’s diamond drilling played a role in promoting. First, the pipe material properties Diamond drilling pipe including the drill pipe (and its joints), core pipe and casing. Small diameter diamond drilling aperture is small, drilling and hole wall clearance is small, drill high speed drilling. Require drilling is good
