摘要
Abstract
A water-soluble phenolic resin composite crosslinking agent was synthesized by the combination of water-soluble phenolic resin and metal ions promote cross-linking agent. The water-soluble excellent multi-methylol phenolic resin was synthesized by two-step method,followed by addition of an appropriate amount of metal ions to improve their gelling properties. The two-step method could promote the reaction of phenol and formaldehyde,so the main product was multi-methylol phenolic resin. The introduction of metal ions promoted cross-linking agent to make excellent gelling properties. This new kind of crosslinking agent was odorless,low toxicity,and efficient. Based on this kind of water-soluble phenolic resin composite crosslinking agent,the partially hydrolyzed polyacrylamide showed good gelling properties. The minimum amount of cross-linking agent was 0.1% with high gelling strength; its gelation temperature could be adjusted from 60~120℃ and its gelling time could be controlled between 8h and 48h. The stability of gel system was more than 60 days. The composite crosslinking agent has great prospects in the field of oilfield water shutoff profile.关键词
