Through the cultivation of two polymer-producing strains of WP1, SP1, determined the suitable growth temperature of bacteria, followed by fermented, we research the growth of the strains and metabolite changes on viscosity and pH values. Results show that at 80 r/min, 120 r/min training conditions, viscosity of strain WP1 is all more than 100mPa•s, the strains of experimental works better than SP1. Therefore, selected strain WP1 identified as strains of microorganisms in thick oilfield combination flooding produced polymers, this strain is identified at last.
