摘要
文中针对封隔器的实际结构,建立了三维光弹性实验模型,通过实验检测出卡瓦的内部应力及卡瓦与套管的接触应力,得到了卡瓦锚爪的应力分布规律,为卡瓦的优化设计提供了理论依据。
Aiming at the actual structure of packer,experimental model of three-dimensional photoelasticity was established,the internal stress of the slips and the contact stress of the slips with the casing were detected through the experiment,the stress distribution rule of the slips fluke was obtained,and thus a theoretical basis was provided for optimized design of slips.
