摘要
综述了近年来油气井固井水泥浆用AMPS基耐高温缓凝剂的研究进展,内容涉及AMPS基阴离子型、两性离子型聚合物抗高温缓凝剂的制备、性能及应用;通过物理化学方法和分子动力学模拟方法研究缓凝剂作用机理的进展。指出两性离子缓凝剂是研究重点,现有研究存在聚合物缓凝剂结构单一,没有系统研究影响聚合物缓凝剂性能的主控因素和各因素的影响规律,缓凝机理研究还主要是基于宏观性能上的假设和描述,阴离子型缓凝剂中引入阳离子对性能改善的内在原因没有探明,缓凝剂分子在井下的形态和结构研究尚处空白,这些因素都极大阻碍当前缓凝剂性能的提升。当今发展起来的分子动力学模拟研究物质微观结构的方法,对其作用机理的解释将起到非常重要的作用。
This paper provides an overview of recent research on AMPS-based high-temperature resistant retarders for cementing slurries,mainly including the preparation,property and application of anionic and amphoteric AMPS-based polymer retarders;as well as investigations into their mechanism through physical and chemical methods along with molecular dynamics simulation methods(MDS).It was pointed out that the research should pay attention to amphoteric retarders,the existing polymer retarders have a single polymer structure,and there is no systematic research on the main controlling factors and the influencing laws of various factors,which affect the performance of AMPS-based polymer retarders.Now,the research on the retarder mechanism is mainly based on assumptions and descriptions of macroscopic performance,and there are few reports on the morphology and structure of retarder molecules in borehole.The combination of experimental research and molecular dynamics simulation will play a very important role in explaining the mechanism of action.
