Abstract: Based on a comprehensive consideration of the effect of temperature field in the fracture on viscostity, leak-off, flow of fracturing fluid and fracture geometry etc, a complete set of numerical models and methods is estabished to calculate hydraulic fracture geometry, including the temperaaure field, flow rate field and pressure field for separate cases of is separately Newtoian and non-Newtonian fracturing fluid as well as settling and suspending proppant measured curves from thxee wells and calculation data are given. Calulation results of this paper, and the results recommeaded by BJ Go. and Halliburton Co, are compared without allowance for temperature changes in the fracture, the numerial methods presented in this paper can be used in hydraulic fracture design calculation and have the advantages of simulating fracturing fluid lass,temperature and pressure changes in the fracture with regults closes to reatity.
