Study On Efficiency Of Bactericide In The Waste Water With Polymer

All sorts of microorganisms living in the system of oilfield water injection, such as sulfate reducing bacteria (SRB), iron bacteria, saprophytic bacteria, and other microorganisms. their growth, metabolism and reproduction which can cause drilling and production equipment, water injection pipelines and other metal materials serious corrosion. At the same time, it can plug pipes and damage reservoir, caused decline in the water injection, oil production and the quality of oil and gas. resulting in great economic losses. Fungicides are used in the vast majority of the quaternary cationic Fungicide -1227 (12 alkyl dimethyl benzyl Chloride), the use of these fungicides containing anionic polymer polymer sewage will react with the polymer, reduce the viscosity of polymers, and do not dissolve in water to form a viscous with the floc, plug and corrosion injection system. If they go into underground rock penetration rate will be lower, and long-term use after the emergence of drug-resistant easy.Based on microbicides and polymers and surfactants compatibility study screened suited to the water containing polyethylene Mian used fungicide, and will conduct a field experiment. Through experiments at the scene of the fungicide dosage concentration, and put in place the means to increase research, identify the most appropriate use of the technology scene. Adoption and ultraviolet disinfection method used by the joint study found the physical and chemical sterilization method with the use of sterilization method, Sterilization can not only reduce costs, but also improve the efficiency of sterilization.
