1. Brief Introduction
Emulsifier for Drilling Fluid SRH-1 is a new gel-type emulsifier developed by China University of Petroleum in accordance with the principle of colloid chemistry. Its appearance is milky white gel or latex, non-toxic, non-fluorescent, and it does not interfere with the geological fluorescence record, and can be used for exploratory well drilling. The product is effective in diesel emulsion, so that the contaminated drilling fluid frictional resistance greatly reduced, which increases bit life , reduces the number of times to drill, shortens the drilling cycle and reduces drilling costs, available for various deep well drilling fluids.

3. Application
Emulsifier for Drilling Fluid SRH-1 is available for temperature resistance over 200 ℃, which can be used for water-based drilling fluids, oil-based drilling fluids. For water-based drilling fluids, oil in water-water type emulsion is developed, while for oil-based drilling fluid, the water in oil emulsion-oil type emulsion is developed. It can be used in marine, land deep wells, exploratory well drilling.
4. Usage and Dosage
Liquid product can be directly added into all kinds of water based drilling fluid system and oil based drilling fluid system.
Initial recommended dosage is 2%~4%.
5. Packaging and Storage
It is packed by polyethylene plastic barrel of 50kg net weight each or galvanized bucket of 200kg net weight each.
It should be stored in cool, dry and ventilation places. Guarantee period is 1 year.
6. Environment and Safety
It is less toxic. No special attention during injection. Avoid contacting with eyes, skin and clothes, otherwise wash with plenty of water.
No swallowing.
