| 摘 要： | 要使稠油热采过程中井筒加热参数适当，必须全面掌握地层岩石及流体热物理性质与井筒温度的关系。建立了井筒温度场的二维数学模型，对影响井筒温度的14种参数进行敏感性分析，结果表明：套管循环热流体的入口温度及注入排量、油井的产液量和地层岩石的比热对井筒和井口采出液体的温度影响较大，在循环热流体加热过程中，加热流体的注入参数存在最优值。图3表1参11

| Abstract: | In order to choose suitable production parameters when hot fluid is circulated in heavy oilfield, it is necessary to understand the relationship between the wellbore temperature and thermophysical properties of the rock and fluid. A 2-D mathematical model is developed for the temperature calculation and the sensibility of 14 parameters influencing the wellbore temperature distribution is analyzed. The analysis shows that the inlet fluid temperature, circulating capacity, fluid production and specific heat of the rock have dominant influences on the temperature of the wellbore and output fluid. Besides, optimal injection parameters exist in the circulation of hot fluid. |
