Abstract: Wellbore hot fluid circulation is a practical technology suitable for the production of high pour-point and high viscosity oil. Its mathematical model is a normal differential and non-linear equation group under the condition of half-consealed edge. The common way of target or conjugate function is not suitable for the solution of this equation group. However, we obtained its analytical solution during the research. The problem of the application of parameter processing and program designing are discussed. This method can be used in project designing of oil field development and the feasibility study of applying the low-temperature heating nuclear to oil fields.
