| titleOfInvention | Shale intercalation inhibitor prepared from environment-friendly hyperbranched polyamino acid |
| abstract | The invention discloses a shale intercalation inhibitor prepared from environment-friendly hyperbranched polyamino acid, belonging to the technical field of oil and gas field drilling, wherein the hyperbranched polyamino acid is synthesized by taking monoprimary amino acid, N-phenylpiperazine and ester compounds containing double olefinic bonds with different hydrophobic chain lengths as raw materials according to the following steps: s1, synthesizing amino acid methyl ester; s2, synthesizing a hyperbranched polyamino acid intermediate; s3 and synthesizing hyperbranched polyamino acid. The shale intercalation inhibitor prepared from the hyperbranched polyamino acid is prepared by matching the hyperbranched polyamino acid with water, wherein the mass ratio of the hyperbranched polyamino acid in the shale intercalation inhibitor is 0.5-3%. The hyperbranched polyamino acid provided by the invention has good biodegradability, is safe and nontoxic, has obviously improved inhibition performance compared with similar shale intercalation inhibitors, is easy to obtain raw materials and low in price, and the provided synthesis method is stable and reliable and is suitable for industrial production. |
