Property:
Clay inhibitor is composed of cation anti-swelling agent, clay inorganic anti-swelling agent and assistants. It has the features of high antiswelling efficiency, long antiswelling time, stabilization under reservoir conditions, no pollution to oily layer, usableness and low cost. It is widely used in medium and low permeability oil fields which contain more clay content to prevent the oily layer clay swelling and movement, and reduce the in-place permeability caused herein.

Usage :
It is used to prevent clay swelling when implementing the yield increase and stimulation treatment of oil and water wells, the pretreatment of oil well transferring to water injection well and the regular production of water injection well. Dilute it with clean water according to the applicable concentration.
In the yield increase and stimulation treatment of oil and water wells, the usage is 1.5%-2.5-2.5%.
In the pretreatment of oil well transferring to water injection well, the usage is 3%.
In the regular production of water injection well, the usage is 0.5%.
