| Abstract: | A new filtrate reducer for fixing well was synthesized using acrylamide(AM),2-acrylamido-2-methylpropane sulfonic acid(AMPS), acrylic acid(AA) and organobentonite as raw materials and (NH 4 ) 2 SO 4 /NaHSO 3 as initiators in aqueous solution. The structure of the copolymer was characterized. The AMPS copolymer was evaluated in fresh water, 4% salt water,saturated salt water, mixed salt water and Ca 2 -containing salt water base muds in laboratory.The results showed that the copolymer was of better thermal stability,tolerant to salts and filtrate loss, and that it could be used in treating many kinds of muds. |
