摘要:
在深井、超深井、大位移井和水平井中,套管接头泄漏和滑脱特性是国内外油气井管柱力学研究的永恒主题。通过调研国内外大量文献资料,探讨了套管螺纹泄漏机理、螺纹滑脱机理研究的思路和研究方向——除实物试验外,有限元法是可行的简便方法之一。运用有限元法,对套管偏梯形螺纹接头和圆形螺纹接头进行了研究,得出了偏梯形螺纹接头在牙侧角为3°、5°和10°时,滑脱载荷随加载过程的变化曲线;圆形螺纹接头在锥度为1/14、1/16和1/17时,滑脱载荷随加载过程的变化曲线。其研究结果,在深井、超深井和复杂井套管柱设计中,为套管接头螺纹的选择提供了理论数据。
Abstract:
Under the deep well, extra- deep well, extend well and horizontal well, the properties of the leakage and jumped - out of the casing connector is the topic that is studied forever at home and abroad in the research of the oil-gas pipeline mechanics. Based on the study of many literatures, the develop object of the premium connections was presented in the paper, the mechanism of the leakage and jumped-out of the threads of casing connection was discussed in detail. The stresses of the connection of the buttress and round threads were analyzed with finite element method (FEM), the curves of the jumped-out loads varied with the time was obtained when the flank angles of the buttress are 3°, 5° and 10° degreed, respectively. With the three tapers 1/14, 1/16 and 1/17, for the round casing connector, the curves that the jump-out loads varied with the loading process were obtained. It provides the theoretical supports for the selection of the casing connectors in the extra-deep well and complex well.
