Chrome Free lignosulphonate is a kind of lignosulphonate drilling mud thinners, both reduced water loss, with high temperature resistant, non-toxic, strong compatibility features,as thinner, suitable for all kinds of mud system.
Features:
Excellent performance of diluent, Reduce the mud filtration effect is remarkable,the performance that used to dilute water mud is better than it used to brine mud. Can be used with other types of mud treatment agent compatibility. This product is not flammable, explosive, non-toxic, non-corrosive, use safety, won’t cause pollution to the environment. Has good emulsification ability.
Usage:
Aqueous solution made up with powder or directly add to the mud, Due to join the thinner that the mud had lower PH, Need to add sodium hydroxide to adjust slurry PH value between 10 ~ 11, have the best effect.Proposed dosage:Fresh water is 1.0 ~ 1.5%（W/V），Brine is 1.5 ~ 2.0% (W/V).
Application:
The thinner is suitable for deep well as viscosity agent is used. vertical wells and technically complex slope can be used in water base drilling fluid viscosity and fluid loss, this product also suitable for offshore drilling and drilling high salt content and saturated salt conditions.
