| titleOfInvention | Copolymer suitable for cutting agent, preparation method and application thereof, saturated brine drilling fluid and application thereof |
| abstract | The invention relates to the field of well drilling in the petroleum industry, and discloses a copolymer suitable for shear raising agents, a preparation method and application thereof, and a saturated brine drilling fluid and application thereof. The copolymer suitable for the shear raising agent contains the structural unit represented by formula (1), the structural unit represented by formula (2) and the structural unit represented by formula (3). The copolymer provided by the present invention can be used as a shear raising agent in saturated brine drilling fluid, and it can maintain high stability in brine, and can have a good viscosity-increasing effect even at a relatively high temperature , to effectively increase the apparent viscosity, dynamic shear force and static shear force of the saturated brine drilling fluid system. |
