Macromolecular Cationic Polymer for Drilling Fluid—JHCHM 2014-01-23 11:55:40 
Introduction
It is white or jonquil grain which can free flow, can be used in water-based drilling fluid, and has a good compatibility with zwitterion treating-agent for drilling fluid. In addition, it can improve rejection capability of drilling fluid and raise the rate of rolling recovery efficiently.
Usage
It can be made into colloid and then added into drilling fluid or added directly, and the addition of it is 0.3%～0.7%.
