Emulsified Asphalt Powder with High-purity for Drilling Fluid—JHEA 2014-01-23 11:59:16 
Introduction
The powder is cationic asphalt with excellent properties instead of sulfonated asphalt, and it is prepared from various oxidated, petroleum, tar and native asphalt by sulfonation, emulsifying, oxidation, surface activation processes and cationic reaction.
Main Features
- a advanced agent;
- a water-dispersible agent, and its suspension is compatible with drilling fluid;
- can fill in pores among different size particles, and has good capacity of plugging and cementing to improve the effect of borehole wall protection and sealing;
- has a good compatibility with other agents for drilling fluids;
- can be used in various types of well and drilling fluid.
Usage
It can be added into drilling fluid, and the addition is 1.0%～3.0%.
