Use of HD-1 high density weighting agent Україна

Time: 2024-10-12
HD-1 high density weighting agent iron powder

     

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 good 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.

characteristic:

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.
