Chrome Lignosulfonate

Chrome Lignosulfonate is one special kind of Lignosulfonate that used as drilling mud thinner . It can resist high temperature and salt; also can easily used with other mixture together.It is mainly suitable to drilling deep well on the condition of complex geology and high mineralization /salinity.
Physical and chemical index:
Item Requirement
Appearance Blackish brown powder
Moisture (%) ≤8.5
PH(10%water solution) 2.5~4.5
Total Cr (%) 3.6~4.2
Mud performance:
Item Fresh water drilling mud Salt water drilling mud
Normal temperature
Apparent viscosity mPa.s ≤30 ≤30
Rate of reducing viscosity % ≥80 ≥65
High temperature
Apparent viscosity (mPa.s) ≤40 ≤45
Rate of reducing viscosity % ≥60 ≥60
A. Characteristics
1. Aiti-high temperature. The resistance to high temperature can reach 150℃to160℃,and the performance of mud can stay the same during the 16 hours.
2. Anti-salt. The performance of 2% salt water mud is better than FCLS (Ferrochrome Lignosulfonate).
3. Dilution .The dilution rate is better than FCLS when used in the same mud.
4.It is suitable to all kinds of dispersed mud due to the excellent thinning property and powerful anti-electrolytes.
B. Application:
Chrome Lignosulfonate can be added into drilling fluid in the form of aqueous solution or powder. To adjust PH to 10.0~10.5,the recommended dosage of thinner should be 0.5~1.0%(W/V).
C. Pakage:
The net weight of each bag is 25kg with paper-plastic complex valve bag.
