Drilling fluid system name

Oxidation gel breaker system for horizontal wells

Matching core finishing agent

Clay stabilizer HCS    Oxidized gel breaker HBK    Corrosion inhibitor CA101-4    Water proof lock agent HAR / drag reducer HUL

System characteristics

1、The Oxidant degradation by oxidant;

2、Polymer macromolecules are degraded into small molecules, CO2 and H20;

3、It can reduce the adhesion between the mud cake particles, while the mud cake loosens.

Application situation

It has been successfully applied in horizontal wells of Dongfang 1-1 gas field and Wenchang 13-1 oil field.
