【摘要】 通过大量的实验室静态实验 ,研究了阴离子聚丙烯酰胺与阳离子聚合物在抗沉淀剂存在条件下的复合凝胶体系。考察了聚合物浓度、交联剂浓度和体系pH值对凝胶性能的影响。该凝胶体系的成胶时间在不同的条件下从几小时至几十小时的范围内变化。可用于油田大剂量的深度调剂作业更多还原

【Abstract】 This paper presents a lot of static test in laboratory.We have researched the compound gel system of polyacrylamide and cationic polymers,and have inspected all factors which have some effect on gel property.Because of different PH values,concentrations of polymers and crosslinking agent,where the antiprecipitant is existed,the time needed for gelling of the gel system is from hours to days.This gel can be used for field of dose depth profile control operation and for raising rate of the crude oil recovery.更多还原
