摘要
基于传热学理论,建立了机采油井井简及其周围地层温度场的数学模型,对不同参数下的井口温度进行了模拟,分析了油井产量、含水率、井深、油管半径、环境温度及地温梯度等参数的影响.
The physical property and rheological behavior parameters of the flow in the wellbore are sensible functions of temperature.It is of fundamental importance to calculate the temperature field for the optimization design of an oil/gas production scheme.Based on the thermal conduction theory,a mathematical model is formulated for the temperature calculation of the wellbore for mechanical recovery wells.The influences of such factors as the well yield,water content,well depth,pipe radius,ambient temperature and geothermal gradient, on the wellhead temperature are investigated.
