In order to improve the prediction precision of inner corrosion rate of oil pipeline, this paper proposed a novel forecast model, which combined the global optimization ability of genetic algorithm an
在油气井挤酸、注水等过程中井筒温度变化快,从而导致注入流体性能发生变化,影响作业效果,同时使井下管柱发生较大的变形,改变管柱的受力状况,甚至导致封隔器管柱的失效.本文根据注入井工艺特点,以热力学和传热学基本理论为基础,建立了注入过程中井筒二维瞬态温度场预测模型,给出了模型的定解条件,并采用有限差分法求解预测模型,为注入作业施工参数的合理选择提供了理论依据.
