Drilling plugging agent

Product features

This product adopts multi - clock composite material, through special technology and surface treatment. The mechanism is to form a layer of low permeability plugging film on the surface of borehole wall, which can stabilize borehole wall, reinforce borehole wall, prevent leakage, protect reservoir and prevent pressure difference sticking through shielding and isolation between borehole wall and formation. Suitable for water - based, oil - based and other drilling fluids. Temperature resistance is up to 350 degrees Fahrenheit can be used during drilling.
