Chrome Lignosulphonate

Property and application:

Blackish brown powder, Chrome Lignosulphonate is a specially prepared thinner used in drilling fluids. It has the characteristics of anti-high temperature and anti-electrolyte etc. Chrome lignosulphonate can keep stable in high temperature: mud performance has no change at high temperature between 150-160℃ after 16 hours. So it’s mainly suitable to deep well drilling when geological situation is complicated and electrolyte is higher. As for its characteristics of anti-salt,Its performance in 4 % salt-base mud is better than FCLS’s and better Rate of dilution than FCLS’s in same mud. It can reduce the filtrate loss of mud, and has powerful-electrolytes capacity. It is suitable to all kinds of mud. When using, adding the product in the form of solution powder into mud directly first, adjusted PH of base mud above 10, then mixed mud’s PH between 9.5-10.5.
