Abstract
The present discloses a mussel biomimetic heat-resistant and salt-tolerant thickener and a preparation method therefor, a gel fracturing fluid and a preparation method and use thereof.
Claims3
A method for preparing a gel fracturing fluid comprising:
- S201:
- contacting a mussel biomimetic heat-resistant and salt-tolerant thickener with water to obtain a reaction system S201,
- wherein the mussel biomimetic heat-resistant and salt-tolerant thickener comprises structural units represented by formulae (a) to (f):
- wherein m is within the range of 60-63, x is within the range of 4-7, y is within the range of 6-10, and z is within the range of 8-10;
- and
- S202:
- under the stirring condition, contacting the reaction system S201 with a cross-linking agent for performing the dissolution and aging reaction to prepare the gel fracturing fluid.
