First, the use of products
Clay swelling shrinkage agent KD-303 is formed by cationic polymer compound multi effect additive compound, which cationic groups under acidic conditions, the oxidation behavior and failure clay lattice, after absorbing a clay and release the moisture sorption, volume shrinkage and swelling, restore stratigraphic channel blocked. The shrinkage swelling agent can effectively remove the blockage caused by the clay mineral particles, and has a good effect of increasing oil injection and increasing oil. Clay shrink swelling agent KD-303 for oil well injection oil wells, anti swelling, acid fracturing etc..

Two, technical requirements

Five, matters needing attention
In the use process, the staff shall wear labor protection supplies, to prevent products splashed into the eyes or contact to the skin, once the occurrence of the above phenomenon, immediately wash with plenty of water, in serious cases, timely medical treatment. Sprinkle on the ground should be as far as possible, for a small number of products with soil landfill, you can also use a large amount of water to wash, wash water into the waste water system.
