Abstract:

In hydraulic fracturing and acid fracturing designs，it is necessary to calculate the fluid temperature distribution in a fracture, This paper has developed a fluid temperature field model when leak-off velocity in the wall is constant. It is simpler than Wheeler's and Whitsitt's models(2)(1)，and as accurate as the precise Wheeler's model. It can satisfy the requirements of practical calculations, In this paper are added calculation examples and curves which can be used for reference in practical calculations.
