摘　　要：在材料、几何非线性接触问题原理上,通过对现有井下Y341- 14 8型封隔器及其类似产品的相关研究,从系统的角度出发,建立了封隔器系统线性及非线性接触有限元分析模型,进一步完善了井下封隔器理论,并为开发井下封隔器工作行为仿真分析软件奠定了理论基础。According to the material and geometry non-linear contacting theory, we set up packer system liner and no-liner contacting finite element analyzing model by researching the Y341-18 packer and other pertinent products in this paper. It established the theory basic for perfecting the downhole packer theory and developing the simulating analyzing software of the packer system. It is a significant theory and it is valuable in practice.
