Abstract: The flow conductivity of propping agent in hydraulic fracture is affected by many kinds of factors. This paper expatiates on the study of effect of formation temperature and Yang’s modulus of rock on flow conductivity of propping agent by using of computer software for the first time at home, presents the quantitative results of effect of the above factors on the flow conductivity of propping agent. The simulation results indicate that when designing hydraulic fracturing for oil and gas reservoirs with higher temperature and lower Yang’s modulus, the effect of these two factors can not be ignored, which has a certain in-struction significance for the optimizing design and implementation of quantitative fractur~ing.
