新型无铬木质素磺酸盐降粘剂LGV研究

A Study of New Chrome-Free Lignosulfonate Viscosity-Reducing Agent LGV

本文介绍了新型降粘剂LGV在钻井液中的降粘能力,初探了LGV的作用机理。此研究对于开发高效、价廉、无污染的木质素类钻井液处理剂具有一定的意义。

This paper introduces the viscosity-reducing ability of new viscosity-reducing agent LGV in drilling fluid and preliminarily inquires into the action mechanism of LGV. This study has a certain sense for developing high-efficient,low-priced and pollution-free drilling fluid additive of lignoses.
