摘要
This paper introduces the application of a reservoir simulator ,which can be used in high pH chemical flood ,to simulating core experiments of chemical flood .The core flood experiments include polymer flood and alkaline/surfactant/polymer (A-S-P) flood under three kinds of different remaining oil saturation . The results of both simulation and experiment show that the remaining oil saturation at the stara of polymer flood does not affect oil recovery when the amount of poymer used is large enough . The value of original oil saturation reflects difference of core pore structure and oil distribution characteristics in core . It is also proven by simulation that the actual value of surfactant concentration in the cores is higher than injected one after alkaline flood due to in-situ generated surfactant . The better history match of differential pressure and oil recovery between simulation and experiment is quite encouraging ,and shows validity of UTCHEM6.0 simulator . Our experience shows that , it is necessary for model parameters used in the simulator to be adjusted properly to account for salinity levels ,pH and in-situ generated surfactants.
