| titleOfInvention | Copolymer of dimer acid-organic amine and shear strength improving agent of water in oil emulsion drilling fluid and drilling fluid |
| abstract | The present subject matter relates to a dimer acid-organic amine copolymer, comprising structural units from a dimer acid, structural units from an alkyl amine, and structural units from an aromatic amine, wherein, the dimer acid is a dimer of oleic acid and linoleic acid, the alkyl amine is one or more of C10-C20 alkyl primary amines, and the aromatic amine is one or more of aniline and aniline with one or more sites on the benzene ring substituted by C1-C3 alkyl. The present subject matter provides a shearing strength improving agent for water in oil emulsion drilling fluids and a drilling fluid containing the shearing strength improving agent. The shearing strength improving agent provided in the present invention can be used to significantly improve the yield point, ratio of yield point to plastic viscosity, gel strength of water in oil emulsion drilling fluids even in a small concentration, and is applicable to water in oil emulsion drilling fluids that contain or don't contain organic clay. |
