水驱油藏聚乙烯亚胺交联聚合物凝胶体系研究进展
Research progress of polyethyleneimine crosslinked polymer gel system in water-drive reservoirs
摘要
Abstract
Polyethyleneimine(PEI)is an environment-friendly and low toxic material.PEI and polymer crosslinked gel system has the advantages of controllable gelation time,high strength of mature gel,high-temperature resistance,long-time stability,and almost unaffected by minerals of reservoir.This paper reviewed the research of various polymer gel systems with PEI as crosslinker.The crosslinking mechanism and the characteristics of those gel systems were clarified.The influence of various factors on the gel system was analyzed.And,the methods to improve the gel performance and successful filed trial were listed,the methods to improve the crosslinking activity of gel system were emphatically analyzed.Finally,it was pointed out that polyacrylamide(PAM)/PEI gel system,as an environment-friendly system,had great application prospects in conformance control and water shutoff of medium and low temperature reservoirs,and it was suggested that the method and the corresponding mechanism of improving the crosslinking efficiency of PAM/PEI system should be studied more extensively and deeply to reduce the loading amount of polymer and crosslinker,and provided a theoretical basis and experimental basis for the promotion and application of this system.关键词
