摘要
针对井下套管射孔后,套管强度会下降的问题,利用有限元分析方法,建立井下套管工作状态的虚拟模型,通过对不同射孔密度和射孔方向的套管进行强度分析,得出不同射孔情况下,套管强度会下降的程度,从而得出为保证套管强度而应采用的射孔方案。
The problem of crush resistance loss of casing when perforated is discussed. A virtual model that can be used in casing in well is set up by finit-element analysis. Through resistance research on density and direction of perforation in the 3-D solid model casing, various results of casing strength are found, thus a reasonable pattern of perforation is presented.
