丙烯酰胺基聚合物压裂液研究进展
|
摘要
丙烯酰胺基聚合物作为一种经济有效的水基压裂液体系,能够满足复杂油藏条件下的黏弹性与携砂性能要求,近年来得到广泛研究并应用于油田的压裂作业中。丙烯酰胺基聚合物压裂液从改性与交联方式的角度可分为基于化学交联的冻胶体系和引入超分子作用的复合体系,综述了2类压裂液体系中聚合物的分子组成、交联方式及作用机制。基于对其适用条件与应用性能的分析,提出未来新型丙烯酰胺基聚合物压裂液研究应增强苛刻环境的适用性、提高其经济有效性及增强对压裂液的微观机理认识。
As a kind of cost-effective water-based fracturing fluid system,acrylamide-based polymer,meets the requirements of viscoelasticity and sand-carrying performance under complicated reservoir conditions.In recent years,it was extensively studied and applied to fracturing operations in various oilfields.From the perspective of modification and cross-linking,acrylamide-based polymer fracturing fluids can be divided into the gel fracturing fluid system based on the chemical cross-linking and the composite cross-linking system introducing the supramolecular effect.The molecular structure,cross-linking manner,and action mechanism of the polymers in the two fracturing fluid systems were reviewed.Based on the analysis of their composition and application conditions,it is suggested that the study on the new acrylamide-based polymer fracturing fluid should be focused on enhancing the application under the harsh environment conditions,improving their economic efficiency and enhancing understanding of the micro-mechanism of the fracturing fluids in the future.
