The Research Of Corrosion Mechanism And Prevention Methods In Weicheng Oilfield

With the continuous development of the Weicheng Oilfield, the a comprehensive water’srising, corrosion problems increasingly prominent, increasingly becoming an important factorin restricting the oil field late high water cut development. Thus oilfield corrosion mechanismwells corrosion mechanism and corrosion protection technology research, to be carried out toprovide a scientific basis for effective anti-corrosion of the Weicheng Oilfield.The full field and literature research and design an effective corrosion research programson this basis. Weicheng Oilfield produced fluid to conduct a comprehensive study analysisbased on the obtained main corrosion factors that affect the Acropolis the oilfield normalproduction Weicheng Oilfield wells corrosion factors, compatibility and oil wells corrosioninhibitor adaptive testing, to improve its formulation, improve the adaptability of a corrosioninhibitor in Weicheng Oilfield; corrosion dosing guidance to improve the utilization ofcorrosion inhibitor and anti-corrosion effect, in order to ease the tension corrosion dosing costfor different water content, different liquid production wells and different degree of corrosioninhibitor flowback law and single well dosing concentrations research; sacrifice anodecathodic protection technology by investigating the Weicheng Oilfield field application of thistechnology in Weicheng Oilfield adapTableility evaluation, screening the best applicationmode, and achieved the expected results; dosing preservation seal corrosion production wellsto eliminate the card can not be cured liquid corrosion inhibitor, preservative effect is evidentin the test wells; against corrosion monitoring techniques, rational choice intensify corrosionmonitoring to optimize the anti-corrosion system, improve the guiding role of corrosionmonitoring techniques preservative dosing adjusted according to the changes in themonitoring data in a timely manner.
