Research status and future trends of the casing collapse problem;
套管挤毁问题研究现状及发展趋势
A finite element model of casing collapse,which can predict the collapse strength,contains the effects of residual stress and geometric imperfections.
预测套管的挤毁失效压力一直是管柱力学研究的热点,针对这一问题,利用在套管外壁粘贴应变片的方法,研究了套管挤毁失效过程中的应变情况。
Objective condition of casing collapse is existing for gypsum-salt bed creep.
但是实钻资料表明 ,四川地区膏盐层套管挤毁现象需要满足一定条件才会发生。
Furthermore, an anti-squeeze casing with high strength was developed and used in more than 600 wells.
为此,中原油田采用三维数值模拟方法研究盐岩层蠕变规律,并定量计算出作用在套管上的横向推挤力,在此基础上开发应用了抗外挤强度大于167MPa的非API高抗挤套管。
