| titleOfInvention | A kind of supramolecular self-assembly clean fracturing fluid and preparation method thereof |
| abstract | The invention discloses a supramolecular self-assembled cleaning fracturing fluid and a preparation method thereof. Calculated by mass percentage, it comprises 0.4%-2.0% of a supramolecular self-assembled emulsion polymer and water; the supramolecular self-assembled emulsion polymer The molecular structure is as follows: The dicationic and amphoteric anions in the fracturing fluid structure of the present invention have the function of self-assembly and winding to form a viscoelastic jelly system in an aqueous solution, and the formed jelly has high temperature stability and salt resistance, and can achieve temperature resistance and salt resistance. , After the fracturing construction is completed, it degrades into a small molecule surfactant without cross-linking function, which has the performance of assisting drainage, and realizes the characteristics of clean and harmless. |
