Petroleum drilling fluid additive and preparation method thereof

ActiveCN112409541AImprove stabilityGood resistance to high temperature and saltDrilling compositionCelluloseEpoxy
The invention relates to a petroleum drilling fluid additive and a preparation method thereof. Xanthate and carboxymethyl cellulose are used as initial raw materials to prepare a macro-molecular RAFTreagent, the macro-molecular RAFT reagent is used for emulsion polymerization with alkenyl sulfonic acid, acrylamide and hydroxyethyl acrylate, then 2,3-epoxy propyl trimethyl ammonium chloride or N,N-dimethyl epoxy propyl dodecyl ammonium chloride is added into the emulsion polymerization system to prepare the petroleum drilling fluid additive. The petroleum drilling fluid additive provided by the invention is a cellulose zwitterionic polymer filtrate reducer, cellulose is taken as a core, and a polymer chain is rich in molecular groups such as hydroxyl, carboxyl, acyl amino and sulfo, so that the polymer has relatively strong hydration capability, is insensitive to salt, strong in high temperature resistance, strong in adsorption capability to clay and good in stability; meanwhile, quaternary ammonium salt is used as a shell layer, the core-shell structure improves the adsorption stability of the filtrate reducer in a high-temperature and high-salt environment, and the filtration loss reducing effect, the high temperature resisting effect, and the salt resisting effect are good.
