| titleOfInvention | Polymer for high-temperature-resistant acidizing and fracturing and preparation method thereof |
| abstract | The invention discloses a polymer for high-temperature-resistant acidizing and fracturing and a preparation method thereof. The polymer is obtained by polymerizing raw materials comprising the following components: acrylamide, methacrylamide, a cationic monomer, a temperature-resistant salt-resistant monomer, a molecular weight regulator, an initiator and water; the mass percent of each component is as follows, based on the total mass of all components except water as 100 percent: 20 to 65 percent of acrylamide; 5 to 15 percent of methacrylamide; 5 to 18 percent of cationic monomer; 15 to 55 percent of temperature-resistant and salt-resistant monomer; 0.01 to 0.5 percent of molecular weight regulator; 0.1 to 0.5 percent of initiator; the total mass concentration of all components except water is 20-35%. The polymer of the invention has good water solubility, acid solubility, instant dissolution, temperature resistance, shear resistance and excellent thickening effect, and can be applied to the fields of acidizing and fracturing construction, enhanced oil recovery operation and the like in oil exploitation at the temperature of over 160 ℃. |
