| 摘 要： | 针对热采井套损十分严重的情况,建立了考虑多场耦合的热采过程井壁受力计算数学模型.借助数值计算软件模拟了热采过程油井周围渗流场和应力场的变化情况,并与辽河油田稠油热采井套损情况对比验证了所建立模型的有效性.通过数值模拟研究分析了热采过程注采参数对套管挤压力的影响规律,研究表明:在开井生产时,随着井底压力的下降,套管承受的...

| Abstract: | For the serious casing damage in thermal recovery,a thermo-hydro-mechanical coupled mechanics model of thermal recovery was established.The multi-physics software was employed to solve the model and simulate the distribution of seepage and stress around the thermal recovery well,and the validity of model was verified by comparing with the data of heavy oil thermal recovery in Liaohe Oilfield.The influence of injection-production parameters on the compression on casing was simulated with the model.The result... |
