Due to the limitation of temperature, it is difficult to break the gel of the oxidized gel-breaking fracturing fluid in the fracturing of low-temperature oil and gas reservoirs, and it cannot be quickly returned, which will cause damage to the reservoir and affect the fracturing effect. The TDH-1 series of low-temperature gel-breaking activators are divided into plant gums and synthetic polymers. Both of them can activate the activity of peroxide gel-breaking agents, so that the fracturing fluid can completely break the gel at low temperature (<20℃), with low cost, simple operation, good stability, and no pollution to the human body and the environment.
