| Abstract: | Water-soluble fracturing temporary plugging agent is used to seal fractured old cracks, build new seams and improve the oil flow channel. This agent can be dissolved into aqueous solution and fracturing fluid gel breaking liquid at 50 ℃, 80 ℃ or 120 ℃,and the dissolution rate increases with the ascent of temperature. At room temperature of 20 ℃, this agent can be dispersed and become stable in the fracturing fluid. Its compatibility with the fracturing fluid and additives is good. The particle size of temporary plugging agent has influence on the temporary plugging effect, the agent combined with particles of different sizes has higher pressure than those combined with particles in the same size. |
