| titleOfInvention | High-temperature-resistant seawater-based polymer fracturing fluid capable of being continuously mixed and prepared and preparation method thereof |
| abstract | The invention discloses a high-temperature-resistant seawater-based polymer fracturing fluid capable of being continuously mixed and a preparation method thereof, and the high-temperature-resistant seawater-based polymer fracturing fluid comprises the following components in percentage by weight: 0.4-0.8 wt% of a thickening agent; 0.3-0.6 wt% of auxiliary synergist; 0.2-0.4 wt% of an activating agent; 0.2-0.4 wt% of metal ion stabilizer; 0.3-0.4 wt% of a temperature stabilizer; the other component is seawater. The invention has the following beneficial effects: the fracturing fluid system uses the water-soluble multipolymer as a thickening agent, can be quickly swelled in high salinity seawater, forms low-viscosity high-elasticity fluid with a strong space structure through the synergistic effect (non-crosslinking effect) between the thickening agent and an auxiliary synergist, has good sand carrying capacity when the apparent viscosity is more than 20mPa & s, is free from bacterial erosion, has the characteristics of good salt resistance, temperature resistance and shear resistance, low damage, cleanness without residues and the like, can be prepared by adopting seawater in batch and continuous mixing, can obviously reduce the offshore fracturing construction cost, and improves the fracturing construction efficiency and the reservoir yield increasing effect. |
