Product Desciption

PRODUCT INTRODUCTION:
Sulfonated brown coal (SMC) is a derivative of brown coal humic acid and is obtained by synthesizing lignite under the conditions of sulfonating agent and suitable temperature. The appearance of the brown coal is brownish-black powder, and it is a high temperature resistant to 200°C~220°C. Freshwater drilling fluid viscosity reducer and fluid loss control agent is a cheap and efficient mud treatment agent.

PERFORMANCE AND USE:
Sulfonated brown coal (SMC) is mainly used for petroleum and geological exploration drilling. In the drilling mud has a significant reduction of filtration and inhibition of viscosity reduction, the product can be directly added to a variety of water-based drilling fluid system, and more with potassium humate, lignite resin, sulfonated phenolic resin and other treatment agents used in conjunction. The general increase is 2.0-3.0%.
