The highlights of this paper include : hoop toughness criterion for longitudinal heat checking of tool joint was introduced firstly ; failure criterion for crescent - shaped wear casing was established according to the results of full - scale collapse tests ; new - typed alloy for hardbanding of tool joint was developed, its property has showed good performance in the tests
本文的主要創新點在於：以現場失效案例分析為基礎，提出了鉆桿接頭縱向熱裂的橫向韌性判據；通過對已磨損套管的實物擠毀試驗研究，確定了不均勻磨損套管的擠毀失效準則；設計出了具有獨立知識產權的鉆桿接頭硬化帶用新型耐磨減摩合金的成分，經實驗室試驗表明其性能可以達到或超過國外同類產品。Special thermowell is manufactured from drilled bar stock to withstand pressure morethan 6. 4mpa, together with convenience in installation for movable connector
特製套管帶活動連接頭，安裝方便，整體鉆孔縮徑式套管結構，耐壓6 . 4mpaThe results have given the reason of tool joint with one side hardbanding and double sides hardbanding could reduce casing wear, and the theoretical foundation and technical guidelines to technology of tool joint hardbanding
分析結果很好地解釋鉆桿接頭單、雙邊敷焊硬化帶降低套管磨損的原理，為鉆桿接頭敷焊硬化帶工藝提供了理論基礎和技術依據。Verification regulation of master gage for rotary shouldered connections thread, casing round thread and tubing thread
石油鉆具接頭螺紋套管圓螺紋和油管螺紋校對量規檢定規程Calibration specification for working gauge of rotary shouldered connections, round thread casing and tubing
石油鉆具接頭螺紋工作量規圓螺紋套管工作量規和油管螺紋工作量規校準規范Thereby, this paper has carried through an in - depth study on wear mechanism between tool joint of drill pipe and casing, problems caused by wear and measures to deal with wear based on researches at home and abroad. the research contents include : in order to reveal mechanism of wear occurred between tool joint and casing, distribution of the contact pressure between the tool joint and casing for different loads was obtained with finite element method. furthermore, the mathematical model of maximum contact pressure and the wear depth on casing was established
所以，本文在國內外研究的基礎上，對鉆桿與套管摩擦磨損的機理、引發的系列問題及其預防措施進行了深入研究，研究內容主要包括：為探討鉆桿接頭與套管摩擦磨損的機理，採用有限元法研究了不同載荷下接頭與套管之間接觸壓力的分佈規律，並建立了最大接觸壓力與磨損量的數學模型。分享友人
