通过切卡柳克导压性和能量的方程建立温度场和压力场的数学函数,推导在渗流存在的条件下单相液体在饱和孔隙层中的温度随时间变化的函数;利用所研究的模型描述井底压力随时间变化时井内温度的变化。为了证明分析模型的成立,将分析模型的结果与数学解进行了对比分析。分析模型建立在单相液体在均质地层中渗流的基础之上。可以利用所研究的模型,解决在井内温度变化条件下确定地层参数的逆问题。
The mathematical function of temperature field and pressure field was established by using the equation of the pressure and energy of Cheikarluk and the function of the temperature of the single phase liquid in the saturated pore layer under the condition of seepage was derived. Based on the model Describe changes in wellbore temperature over time. In order to prove the establishment of the analytical model, the results of the analytical model are compared with the mathematical solutions. The analytical model is based on the seepage of single-phase fluids in a homogeneous formation. The model studied can be used to solve the inverse problem of determining formation parameters under in-well temperature changes.
