Characteristic analysis and control measures of reducing substance in polymer flooding injection system

When the injection pump was regularly cleaned at the injection station, it was found that there was a large amount of “yellow-colored viscous strip-shaped substance” in the system, which caused serious blockage of the filtering device of the injection pump and serious corrosion of the equipment. Through the analysis of the composition, formation cause, formation mechanism, distribution range and damage caused to the system, it is considered that it is mainly a metabolite produced by bacteria. For this reason, the next step of sterilization measures was formulated to achieve better results.
