Chrome Lignosulfonate

Description

Chrome lignosulfonate is a specially thinner used in drilling fluids. It has the character of anti-high temperature anti-electrolytes etc. It is mainly suitable to the conditions of complex gelogic and high or content in drilling deep well. Physical and chemical index : Item Requirement Moisture (%) ≤ 8.5 Material insolution to water (%) ≤ 2.5 Calcium sulfate (%) ≤ 3.0 Total Cr (%) 3.6~4.2 Cr complex (%) ≥ *5.0 Mud performance: Item Fresh water drilling mud Salt water drilling mud Normal temperature Apparent viscosity mPa.s ≤ *0 ≤ *5 Rate of reducing viscosity % ≥ *5 ≥ *0 High temperature Apparent viscosity mPa.s ≤ *0 (**0℃ï&frac*4;‰ ≤ *5 ï&frac*4;ˆ**0℃ï&frac*4;‰ Rate of reducing viscosity % ≥ *5 ï&frac*4;ˆ**0℃ï&frac*4;‰ ≥ *0 ï&frac*4;ˆ**0℃ï&frac*4;‰ 1、Aiti-high temperature **0~**0 ℃ , *6 hours it`s mud peformance keep constant. 2、***** 2% Salt water , it`s mud performance is better than FCLS (Ferrochrome lignosulfonate). 3、In the same mud , it`s dilution performance is better than FCLS. 4、With excellent thinning performance and filtration control capacity and powerful anti-electrolytes. It is suitable to all kinds of muds. Application: Chrome lignosulfonate may be added into drilling fluids either in the form of solution or powder. PH:*0.0~*0.5, As a thinner 0.5~1.0%(W/V).
