| Abstract: | High strength water plugging agent CY 98 is a polymer(PAM)/resin and water glass mixed gelling fluid developed for selective water plugging in production wells at high temperature and high salinity water flooded reservoirs. In this paper the formulation, constituents and rheological behavior of gelling solution CY 98, the conditions of gel formation, the morphological structure, stabilities, and dynamic mechanical properties of the gel formed are studied experimentally and discussed. |
