目前，大多数油田都是应用注水开发技术开发的。然而，由于注入液与地层水的不配伍性等原因，这项技术往往伴随着无机垢在水、油管和设备壁上的沉积。硫酸钡和锶对通常用作结垢溶解剂的酸有很强的抵抗力。在本工作中，我们研制了一种新型的基于螯合剂的碱式硫酸钡锶垢溶蚀剂SA-209。通过实验和分析，对影响阻垢效果的盐浓度、反应时间、pH值、温度等重要参数进行了评价。该溶蚀剂除垢速度快，设备和管道腐蚀小，对环境友好，在油田有广阔的应用前景。
At present, most oilfields are developed by applying water-flooding technology. However, this technology is often accompanied by inorganic scale deposition on water- and oil-pipe and equipment walls due to the incompatibility between the injection fluid and formation water and for other reasons. Barium and strontium sulfates are highly resistant to the acids that are generally used as scale dissolvers. In this work, a new chelating-agent-based alkaline barium- and strontium-sulfate scale dissolver named SA-209 has been developed. Many of its important parameters such as salt concentration, reaction time, pH value, temperature, etc. that affect de-scaling efficiency are evaluated by experiments and analysis. This dissolver has a high de-scaling rate and low equipment and pipe corrosion, is environment-friendly, and so would have a promising application in oilfields.
