1. For oil-based mud, with oil as dispersing medium and oxidized asphalt as dispersed phase, prepare special drilling fluid to improve the viscosity and shear force of drilling fluid and reduce the filter loss.

2. It is used as oil-wrapped water emulsion drilling fluid to prevent shale hydration expansion and has a good anti-collapse and anti-card effect.

3. Oxdized asphalt as a dispersed phase has high bitaltic content.

4. For high-temperature exploration Wells, drilling, core and salt layer of the production layer.

Implementation standard: Q / SHCG 104- -2017
