Product introduction

Sulfonated brown coal SMC is a derivative of brown coal humic acid, which is obtained by the synthesis of brown coal after alkalization, sulfonation, and cross-linking of chromium salts at appropriate temperatures. The appearance is dark brown powder. It is a cheap and efficient mud treatment agent, which is used as a viscosity reducer and fluid loss inhibitor in fresh water drilling fluid with excellent high temperature resistance. It can be used in various water-based drilling fluid systems directly and can be used in combination with a variety of treatment agents. General dosage is 3-5%.

Usage methods

1. This product has the dual effect of reducing fluid loss and viscosity reduction

2. With excellent temperature resistance, it can resistant 200-220 °C high temperature, especially suitable for using in deep wells
