前言在油气田开发、油气集输及加工过程中,由于不同程度地含有H_2S、CO_2、有机酸及卤水等腐蚀介质,从而造成井口设备、集输管线及设备的严重腐蚀。合理地选用缓蚀剂,能有效地减缓钢材的腐蚀。为了提供适合现场条件使用的缓蚀剂,首先必须在室内准确地评价其防腐效果。在评价油气田缓蚀剂方法中,挂片失重法仍然是最经 Preface In the process of oil and gas field development, oil and gas gathering and processing, corrosive media such as H 2 S, CO 2, organic acids and brine are contained to varying extents, resulting in severe corrosion of wellhead equipment, gathering pipelines and equipment. Rational use of corrosion inhibitors, can effectively reduce the corrosion of steel. In order to provide a corrosion inhibitor suitable for use in the field, it must first be accurately evaluated in the interior for its corrosion protection effect. In the evaluation of oil and gas corrosion inhibitor method, hang weight loss method is still the most viable
