| Abstract: | Filtration reducer FLA is a copolymer of 2-acrylamide-2-methyl propane sulfonic acid CAMPS) , and other vinyl monomers. It possesses the advantage of good temperature resistance (over 2000, good tolerance to salts and calcium compounds. It can be used in fresh water, sea water, saturated salt water and calcium chloride mud systems. |
