Product Description

Non-fluorescence Anti-sloughing and Filtrate Reducer for Drilling Fluid-----PA-2

1.Brief Introduction

 Non-fluorescence Anti-sloughing and Filtrate Reducer for Drilling Fluid researched and developed by UPC (China University of Petroleum) has been extensively applied in local major oilfields and well received by clients. It won Second Prize of Shandong Province’s Technology Progress in 1996.

2. Main Components and Function

PA-2 is the graft copolymer of potassium humate and cationic monomer. The introduction of positive ion enhances the capacity of anti-sloughing and filtration loss, and especially improves the effect of drilling fluid viscosity reduction.
