[Applications]
Quartz sand is primarily used as a proppant in the extraction of oil and natural gas. In hydraulic fracturing operations, it is mixed with high-pressure fluids and injected into the reservoir to create fractures, enhancing permeability. It keeps fractures open and forms a high-conductivity pathway from the reservoir to the wellbore, thereby increasing hydrocarbon production.
[Product Advantages]
1. High compressive strength;
2. Stable chemical properties;
3. Excellent corrosion resistance;
4. Strong conductivity;
5. Low production cost.
[Usage and Dosage]
The dosage depends on the wellbore diameter and depth, as well as the ratio of fracturing fluid to quartz sand.
[Packaging]
Typically packaged in bulk bags or in bulk, with net weights of 1000kg or 1500kg. Custom packaging is available upon request.
[Storage Conditions]
Store in a dry and ventilated area, and avoid direct sunlight. Prevent contamination and do not mix different mesh sizes in storage.
