Deflocculation and Fluid Loss Agent for Drilling Fluid—SPNP 2014-01-23 11:49:01 .jpg)
Introduction
It is a lignosulfonate with water solubility and with functions of controlling filter loss, improving mud cake quality and visbreaking efficiently. In addition, it has a stable performance, a good compatibility with
various treating agent and a low price. As a new agent with excellent resistance to damage, it can be applied to different water-based drilling fluids.Usage
It can be added into drilling fluid, and the addition is 10～20Kg/cm3.
