| titleOfInvention | A kind of cationic gel acid thickening agent and preparation method thereof |
| abstract | The present invention relates to a kind of cationic gel acid thickening agents.The gel acid thickening agent is the copolymer of four kinds of acrylamide, phosphorous cationic monomer, dimethyl diallyl ammonium chloride and 2- acrylamide-2-methylpro panesulfonic acid monomers.The invention further relates to the preparation methods of above-mentioned cationic gel acid thickening agent, this method chooses phosphorous cationic monomer resistant to high temperature, gel acid thickening agent is prepared using " two step method of temperature-control by ", to improve the molecular weight of product, obtained cationic gel acid thickening agent have swelling time is short, heat resistance is good, residual acid return row it is high-efficient, the advantages that small to reservoir damage, can satisfy the acid fracturing construction requirement of 140 DEG C of reservoirs. |
