摘要
稠油开采中注入热蒸汽时 ,套管柱除受正常应力外 ,还由于套管柱与水泥环地层热胀系数不同而产生很大的热应力。采用弹性力学的位移解法对该问题进行求解 ,得到了管柱的应力解析式 ,为进行管柱设计和选择提供了理论依据。
Steam injection is widely used in heavy oil recovery In addition to normal stress exerted on casing string,a larger thermal stress is arisen due to the difference of heat expansion between casing string and cement sheath A solution for this problem is found by using displacement solution of elastic mechanics and an analytical solution is obtained to provide a theoretical basis for designing casing string
