摘要
在油气田分层开采工艺中,封隔器是分隔地层的重要部件,胶筒和套管间的接触应力决定了封隔器工作的可靠性和寿命。通过对超弹性材料的理论分析,建立了胶筒有限元模型,采用非线性有限元方法对胶筒工作状态进行数值模拟,研究了胶筒工作过程中不同弹性常数对胶筒和套管间接触应力分布的影响。结果表明随着弹性常数的增加,胶筒接触压力逐渐增大。
Packer is an important component separate strata for departing different layer in oil and gas field, contact stress between cones and the sleeve determine the reliability and life in packer working. Through theoretical super-elastic material analysis, the finite element model of rubber tube is established to simulate rubber tube working state simulation by using non-linear finite element mathod. The distribution of contact stress between the casing and rubber tube are studied and the sealing performance at different constants of elastic is calculated. The results show that with the increase of the elastic constants, the plastic tube contact pressure increases.
