| titleOfInvention | A kind of oil and gas field fracturing fluid thickener and preparation method thereof |
| abstract | The invention discloses a preparation method of a fracturing fluid thickener in an oil and gas field, which comprises mixing macromolecules such as carboxymethyl cellulose (CMC), polyvinylpyrrolidone (PVP) or polyacrylamide with sulfur powder S, and then Under the action of mercapto, the mercapto group is successfully introduced into the long chain of macromolecules, and the modified thickener has strong sand-carrying ability in fracturing, good thickening and oil removal effect, and low price, which is suitable for mass production. Compared with natural polysaccharides, they are more adaptable to complex formation environments, and synthetic polymer thickeners play a greater role in high-temperature deep well fracturing. |
