| titleOfInvention | Shale intercalation inhibitor prepared from ultra-low molecular weight branched tertiary amine polyamine |
| abstract | The shale intercalation inhibitor is prepared by mixing ultra-low molecular weight branched tertiary amine polyamine and water in proportion, wherein the ultra-low molecular weight branched tertiary amine polyamine is prepared by a step-by-step synthesis method or a one-pot synthesis method of a polyamine compound and a tertiary amine compound containing olefinic bonds, wherein the polyamine compound is one of alkyl diamine, polyethylene polyamine and low molecular weight polyamine. The ultra-low molecular weight branched tertiary amine polyamine provided by the invention is nontoxic and harmless, the synthesis method is simple, the yield is high, the raw materials are simple and easy to obtain, and the preparation method is suitable for large-scale industrial production. |
