Multi-polymer fluid loss agent for oil well cement and preparation method of fluid loss agent
The invention discloses a fluid loss agent for multipolymer oil well cement and a preparation method thereof, and belongs to the technical field of fluid loss agent preparation. The fluid loss agent for the multipolymer oil well cement is prepared from the following components in parts by weight: 42 to 56 parts of high-molecular polymer, 4 to 6 parts of bentonite, 1 to 3 parts of disodium ethylene diamine tetraacetate, 10 to 13 parts of composite hydrating agent, 8 to 12 parts of distilled water and 0.2 to 0.4 part of ammonium persulfate, the high-molecular polymer is prepared from dimethylamino propyl acrylamide, 2-acrylamido-2-methylpropanesulfonic acid, glycidyl methacrylate, 3-propyl-2-olefin acyloxy propane-1-sodium sulfonate and 2-aminoethanethiol, and the molecular polymer is prepared from the following components: 2-dimethylamino propyl acrylamide, 2-acrylamido-2-methylpropanesulfonic acid, glycidyl methacrylate, 3-propyl-2-olefin acyloxy propane-1-sodium sulfonate and 2- the composite hydrating agent is prepared from acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, sodium lignin sulfonate, corn fiber and butyl succinic anhydride. The fluid loss agent prepared by the method has excellent fluid loss performance, temperature resistance and salt resistance.
