v HD-1 high density weighting agent
HD-1 is a high-density weighting agent synthesized from various metals, and processed by ultra-linear processing and ultra-fine spheroidization technology.
The particle size is 200~250 meshes, and the density is greater than 7.4, and its specific gravity is much higher than that of the traditional barite weighting agent 4.6~5.05. It has a good spherical particle shape and appearance, and the drilling fluid weighting agent can be recycled and completely acidified, and the acidification rate can reach 94.5%. After being used in cementing cement slurry, it has god dispersion and suspension, and the density of cement slurry can reach 2.4~2.8g/cm3.
In drilling and production operations, not only water-based mud but also oil-based mud can be prepared, and its performance is superior to that of a traditional weighting agent.

Compatibility of cement slurry | Generally | excellent |
Fineness, mesh | 80~120 | 200~300 |
Fineness,g/cm³ | 4.60~5.05 | 6.8~7.2 |
Density of cement slurry that can be prepared,g/cm³ | ≤2.4 | <2.8 |
Prepare cement slurry 2.4g/cm³,with the dosage of BW0C% | 108~110 | 88~92 |
Cement slurry 2.4g/cm³，compressive strength MPa(24h,68°C) | 13.8 | 18.2 |
Performance characteristics
1.The density is higher than that of the existing weighting agent, and the density of the prepared cement slurry reaches 2.4~2.8g/cm3.
2.Prepare cement slurry with the same density, and the dosage is less than the existing traditional weighting agent, thus saving the cost. Suitable for national standard G-grade and A-grade oil well cement.
3.The weighting agent of the prepared high-density oil-based drilling fluid can be recycled and completely acidified.
4.The prepared cementing fluid has good dispersibility and suspension, and its fluidity and stability have good coordination.
5. API24-hour cement paste strength is higher than that of traditional weighting agent.
