在油气田开发过程中,硫酸钡/锶垢最难除去,最好的方法是加入硫酸钡/锶防垢剂对其进行预防和控制。介绍了效果较好的常用聚合物防垢剂的合成原理、制备及最佳使用条件和性能,以及硫酸钡/锶防垢剂分子中常见的螯合基团。 Barium sulfate / strontium sulfate is the most difficult to remove during the development of oil and gas fields. The best method is to prevent and control it by adding barium sulfate / strontium anti-scaling agent. The synthesis principle, preparation, optimum use conditions and properties of commonly used polymeric scale inhibitors, as well as chelating groups commonly found in barium sulfate / strontium scale inhibitor molecules, are introduced.
