摘要
石油天然气行业标准——《油田注水缓蚀剂评价方法》提出的缓蚀率计算公式由于未考虑酸洗空白损失质量和试件表面积的影响，因而是不适宜的。基于此，提出了以腐蚀速率为基础计算缓蚀率的新公式。经试验实例验证，新公式不仅消除了“标准”计算公式的不足，而且可正确反映试验结果。因而可在实际中推广应用。
The formula for calculating corrosion rate recommended by the Petroleum Industrial Standard is not favourable because of neglecting the influence of a sample’s blank loss and surface area. A new calculation formula is proposed based on the corrosion rate of inhibitors.The formula is verified with an example for calculating corrosion tests,showing that the newly proposed formula is capable not only of reflecting test results but also of using in practice
