Fracturing fluid viscosity-controlling agent to be used in hydraulic fracturing |
| abstract |
[Problem] To provide: a fracturing fluid viscosity-controlling agent, which is capable of maintaining the high viscosity of the fracturing fluid during fracture formation in hydraulic fracturing and of reducing the viscosity during recovery of the fracturing fluid; a fracturing fluid comprising said viscosity-controlling agent; and a crude oil or natural gas drilling method using said fracturing fluid. [Solution] This viscosity-controlling agent, which is used for controlling viscosity changes of a fracturing fluid used in hydraulic fracturing, comprises polyalkylene oxide and a viscosity-reducing agent and is a tablet. |
