摘 要:为了解决因负摩阻力过大而导致的井壁破坏的问题,文中研究并提出一种新型的可缩性井壁接头方案。并以祁南矿北风井的可缩性井壁接头为优化对象,通过理论计算和数值模拟相对比的方法对该接头方案进行优化。ANSYS数值模拟的结果表明,井壁接头的水平和竖向承载力极限值分别为28、22.4MPa;在增加弧形板后,井壁接头的外立板的厚度相比优化前减小了10mm;该双立板可缩性井壁接头优化设计方法明显节省了材料成本,提高了井壁接头的安全系数,可以为后续类似井壁接头设计提供参考。In order to solve the problems of wellbore damage caused by excessive negative friction,this paper proposes a new type of compressible wellbore joint.Taking the joint of the Beifeng shaft in QinanMine as the optimization object,it is optimized by theoretical calculation andnumerical simulation.The results of ANSYS numerical simulation show that the horizontal and vertical bearing capacity limit values of the shaft wall joint are 28 and 22.4MPa,respectively;After the arc plate is added,the thickness of the outer vertical plate of the shaft wall joint is reduced by 10 mm compared with that before optimization.The optimization design method of the shrinkage shaft wall joint of the double vertical plate obviously saves the material cost,improving the safety factor of the shaft wall joint,which provides reference for designing similar shaft wall joint in the future.
