摘要:
针对稠油热采井套管损坏率远高于普通油井的现象,以辽河油田锦州采油厂锦25区块的热采井为研究对象,应用热流固耦合理论和有限元数值分析方法,建立了套管-水泥环-地层的三维有限元模型,通过ADINA数值模拟,对比研究同一区块中热采井套管和常规井套管的变形情况,定量计算套管承受的剪应力、拉应力以及有效应力随时间的变化关系。计算结果表明,套管受到的有效应力、剪应力以及发生的应变随时间的推移而增大,曲线趋势均为先缓后增,热采井套管的应力及应变明显大于常规生产井。
Abstract:
It is common that the casing damage rate of thermal recovery well is much higher than that of common oil well, for which a typical three dimensional finite element model based on thermal-fluid-structural interaction theory and finite element method is constructed. Using this model we simulate the thermal recovery wells in J25 block of Jinzhou oil production plant of Liaohe Oil Field Company. Thermal recovery well’s casing deformation is contrasted with the normal well’s, the change of casing shear stress, tensile stress and effective stress is quantitatively calculated by the numerical simulation of ADINA. The result shows that the effective stress, shear stress and strain of casing increase with time and all their curves are from gentle to steep. The stress and strain of the casing in the thermal recovery well are obviously larger than that of the conventional production well.
