1.
The influence of high pressure on thread contact stress of casing joints in gas wells;
高压对气井套管接头螺纹接触应力的影响研究
2.
In high-temperature (HT) -high-pressure (HP) gas wells and steam injection wells, the heat stress caused by temperature difference had great effect on contact pressure of casing joints.
在高温高压气井或注蒸汽的热采井中,变温引起的温度应力(即热应力)将对套管接头的接触压力产生一定的影响,高温差引起的套管接头的接触压力分布变得更加不均,当温差达到一定值时,套管接头内的等效应力将接近材料的屈服强度,使螺纹接触处进入塑性变形状态,从而影响了套管接头的密封性。
