Oilfield water injection, acidification, such as oil production process, corrosion inhibitor as anticorrosion technology the necessary product, its quality is directly related to its application effect and economic benefit of oil field. Corrosion rate is the use of performance evaluation corrosion inhibitors main index, at present, various oil and corrosion inhibitor evaluation test USES is the rate the oil industry standard SY/T5273oil field with produced water corrosion inhibitor performance evaluation method of corrosion rate, test results, repeatability is poor dispersion. In order to improve the corrosion inhibitor testing results of repeatability, accuracy, for management departments to provide an objective, fair and credible inspection data, through the influence from testing results of relevant factors of each link, the detection of the shortcomings of the possible was analyzed, and through experiment, and put forward the scientific and effective for the improvement measures of corrosion rate, make the results of detection repeatability is greatly increased.The laboratory authentication, process, the recognition of the uncertainty is more and more strict requirements. Through the indoor experiments, the atmospheric corrosion and corrosion rate under static test results are analyzed and discussed from the instrument equipment, environmental conditions, and personnel, and other aspects of the influence factors to the comprehensive evaluation, evaluation and a standard requirements under the condition of atmospheric corrosion and corrosion rate indoor static testing results of uncertainty.
