General Introduction

Sulfomethylated Phenolic Resin SMP-I is a copolymer of formaldehyde, phenol and sulfomethylation agent under appropriate conition. It has the characteristics of good water solubility, high temperature resistance, strong effect of salinity resistance and lowering filtration loss. It is a highly effective mud treating agent.

Function Mechanism

SMP-I is a kind of anionic filtration loss control agent. Its molecule has many kinds of faculties of ions, which adsorb on the surface of particle and form the adsorbed hydrated layer, meanwhile improve electrokinetic potential, agglomerated mechanical resistance and electrostatic repulsion of clay particle, therefore, strengthening the coagulation stability of clay particle, maintaining and increasing fine soil grain content in the multi-level distributed mud, finally, facilitating fine and compact mud cake and lowering fluid loss.

Features

•  It can improve mud cake quality and lower filtration loss.

•  Its fluid loss effect is scarcely influenced by high temperature.

•  Good water solubility and strong salinity-resistance.

•  No flocculation and no thickening.

•  Good compatibility, used in both dispersed and non-dispersed drilling fluids

•  Convenient to use and maintain, directly added or mixed with water.
