Composite plugging agent

Compound plugging agent is used to be injected into the oil or the vicinity of downhole, it can generate enough set according to the concentration of chlorine dioxide, chlorine dioxide has a strong oxidation, oxidative degradation of the near bottom zone of the polyacrylamide, xanthan gum, guar gum, sesbania gum and other polymers, the viscosity decreased greatly, the liquidity is better from the bottom, easy to remove, chlorine dioxide concentration has adjustability, stable quality, convenient transportation, storage, less corrosion of the equipment and piping.

Physical and Chemical Indicators:

Ø  Light yellow liquid

Ø  Miscible with water

Ø  pH≤2

Ø  Strong corrosive

Ø  Main components: CH3COOH, NaCLO, HF etc.
