针对大港油田枣园地区自来屯掺水系统水质矿化度高、结垢严重的特点，在对大港油田枣园地区自来屯掺水系统水质及垢样组成的分析基础上，从温度升高，ｐＨ值、各种成垢离子含量、矿化度、管壁粗糙度等因素对成垢量的影响及结垢过程中溶液ｐＨ值的变化进行了详细研究，温度升高，ｐＨ值增大及重碳酸根离子含量增大结垢量明显增加．特别是ｐＨ值增大，成垢量增加更为显著．该实验结果为大港油田枣园地区自来屯掺水管线成垢量的预测、阻垢和清垢提供了依据 Based on the analysis of the water quality and scale composition of the Zilantun waterworks in Zaoyuan area of ​​Dagang Oilfield, The effects of high, pH, various scale-forming ion content, salinity, wall roughness and other factors on scale formation and the pH value of the solution during scaling were studied in detail. The effects of temperature, pH value Large and heavy bicarbonate ion content increased significantly increased the amount of scaling. In particular, the pH value increased into a more significant increase in scale. The experimental results provide a basis for predicting scale formation, scaling and scaling in Zitun waterworks in Zaoyuan area, Dagang Oilfield
