Analysis of the influence of wellbore environmental factors to SRB growth and corrosion

After entering the field development of high water, corrosion caused by sulfate-reducing bacteria caused a serious impact on production. The growth of sulfate-reducing bacteria was contact with the wellbore temperature, p H and the changes of formation water salt content(such as SO42-). This paper studied the affection of environmental factors in the wellbore to the sulfate-reducing bacteria growth, such as temperature, p H and dissolved salts.And it was analyzed that the SRB growth and wellbore corrosion variation.
