Sulfonated Lignite SMC as Heat-Resistant Filtration Reducer for Drilling
1. Property
Sulfonated lignite is a lignite humic acid derivatives,it is obtained of the lignite under the conditions of the sulfonating agent and proper temperature. It\'s brown-black powder appearance. It is a kind of fresh water drilling viscosity depressant and filtration loss control agent, can resistance to 200°C~220°C high temperature. It is a kind of cheaply-priced and efficient mud conditioner

3. Use
Sulfonated lignite mainly used in petroleum, geological exploration drilling. In the drilling mud, it has a significant role in filtrate loss reduction and viscosity reduction control.It can use with many kinds of drilling fluid together directly. Frequently used with Humic acid kalium, SPNH, Sulfonated phenol formaldehyde resin, etc. Normal dosage is 2.0-3.0%.
