玉门油田酒东采油厂目前用处理后的采出水作为注入水水源。针对注入水及地层水的离子成分特点,开展结垢类型研究,并主要根据混合比、温度、pH值、压力等因素开展结垢影响因素分析,得出垢型为CaCO_3和BaSO_4垢,主要为前者、注入水与地层水以9:1的比例混合时结垢量最大、结垢量与pH值和温度成正比,与压力影响较小。通过实验结果选定阻垢剂,优选出阻垢剂GY-405,并确定最佳浓度120 mg/L,弱酸性阻垢效果最宜,阻垢率可达到91.91%。 Yumen Oilfield wine production plant currently used after the treated water as injection water source. According to the characteristics of ionic components in injected water and formation water, the types of scaling were studied, and the influencing factors of scale formation were mainly analyzed according to mixing ratio, temperature, pH value and pressure, and the scale types were CaCO_3 and BaSO_4, mainly The former, the injection of water and formation water at the ratio of 9: 1 mixing the largest amount of scaling, scaling and pH and temperature is proportional to the pressure and less affected. Based on the experimental results, we selected scale inhibitor GY-405 and the best concentration of 120 mg / L was chosen as the best. The scale inhibition efficiency was 91.91%.
