INNOVATIVE STUDY ON CONTROL MICROBE CORROSION OF PETROLEUM PIPE

摘要

The feasibility of Bacillus, yeasts and heterotrophic bacteria compete with sulfate reducing bacteria (SRB) to control the Microbe corrosion. The central combination design model was used to investigate the effect of bacterial combinations on corrosion rate. The conclusion of coculturing them is that it is not very evident to control the corrosion and improve the oil, which probably account for the competition among them and the inhibition from H2S. But to some extent, combining the Microbe corrosion control and Microbe the oil recovery is feasible.
