| Abstract: | This paper presents an amphoteric polyacrylamide,FT-213, BY type crosslinkers (mainly BY-91) and FT-213 based aqueous gelling fluids for modifying injectivity profile in water wells. These fluids consist of FT-213,a crosslinker, phenol and a gelation promotor. The gelation reactions and the mechanizms involved are discussed.The formulations and gelation conditions are established for the highest gel viscosity.The plugging capacity and related characteristics are measured through some cere tests.The adsroption of FT-213 on rock is stronger than that of anionic polyacrylamides.The field uses of these fluids for modifying injectivity profile in 27 operations in Block Jin-16, Liaohe, are successful. |
