摘要(Abstract)：

针对全国油层套管大量损坏这一事实,本文将粘弹性理论引入套管围压的分析中,利用弹性—粘弹性相应原理,计算了粘弹性围岩中套管围压的大小,分析了油井工作状况及时间变化对套管围压的影响,得到了许多有益的启示。通过和有关文献对比表明,本文的计算简捷易行,结论和实际情况相符。
ABSTRACT In view of the fact that a lot of well casings in oil producing wells and water injection wells in oilfields in China have been damaged, in the paper, the theory of viscoelasticity is used to analyse the external pressure on well casings. External pressures on well casings in viscoelastic bounding rocks arc calculated with the relative principles of elasticity-viscoelasticity, and the effects of working cond itions of both production wells and water injection wells and changes in time on the external pressure on well casings are also analysed, a lot of helpful informat ion has been gained. Compared with other related papers, the calculation method-described in this paper is simple and easy to Use, and the conclusions in agreeme nt with the actual conditions.
