Characteristic：

1. It has better clay dispersion than the commonly used fatty acid salts and other products;

2. It has good inhibition ability for the clay hydration expansion.

3. It is not disadvantageous for the rheology and filter loss of drilling fluid.

4. This lubricant can through a layer of chemical adsorption film on the shaft lining and drilling tool, thereby reducing the friction coefficient between the drilling tool and the shaft lining, and improving the lubrication performance of the drilling fluid;

5. It can be used in the drilling operation of in horizontal wells, directional wells and large displacement wells in oil and gas fields.

6. The reducing rate of lubrication coefficient ≥ 80%

7. It has high temperature resistance 180℃, can be used for deep drilling operation.

8. salt resistance, calcium resistance and can be applied to a variety of fresh water, sea water, salt water drilling completed fluid.

Usage: directly add amount of 0.5 ~ 3% according to the amount of circulating slurry into the circulation well (the actual dosage is determined according to the local soil conditions ).

Package : According to clients’ requirements.
