Abstract:
Microorganisms were obtained by separation and purification experiment from waxy oil production wells in Daqing Oilfield. The paraffin removal strain was named for S1, and the biological surfactant strain was named for G1. Microscopic and morphological examinations showed strain S1 was to be Bacillus Subtilis and strain G1 was to be Bacillus Cereus. As an indicator of the degradation of paraffin, strain S1 and strain G1 were added in different proportions, the optimum proportion was 5:2. In this proportion the degradation rate of paraffin could reach to 64%, the prevention rate of paraffin could reach to 55%. By experiment after mixed bacteria group treatment, the viscosity of crude oil reduced from 36.9mPa•s to 27.8mPa•s, the reduction rate of viscosity was 24.7%, and the freezing point of crude oil reduced by 3.6°C, paraffinic hydrocarbons of crude oil were degraded.
