| 1 | Composite polymer networks of polyacrylamide and modified amino resin-polyurethane for oil field water shutoff显示文摘SINCE water emitting in oil wells is a general problem in developing oil fields, the workers inthe world put quite an emphasis on water shutoff. In recent years, the study on develop-ing a novel and highly effective water plugging agent has become an important technical mea-sure for controlling water emitting in the middle and later periods of an oil field. A highly ef-fective water plugging agent can form gel, gradually swell in water and shut off water, but oilcan get through. It also has suitable resistance to pressure and high temperature and a longservice life. Only when the water shutoff agent can form a composite polymer network (CPN) | Liu, QP Hou, SJ Ha, RH Yao, KD | 1997 | Chinese Science Bulletin1997，42，15： | 3 |
