Products Description
Ceramsite sand plays an important role in the oil and gas extraction process. Its main function is to enter rock cracks as a filler during the fracturing process to support the cracks from closing due to stress release, thereby maintaining high conductivity, allowing oil and gas to flow smoothly, and increasing production.
The following are several important functions of ceramsite sand:
Support cracks: Fracturing proppant is injected into the formation, and enters the formation with the high-pressure solution to fill in the rock formation cracks, playing the role of supporting the cracks from closing due to stress release. This can effectively support artificial fractures, keep the fractures open, and improve the fluidity of oil and gas.
Increase production: The use of oil fracturing proppant can increase the production of oil wells by 30-50%, and can also extend the service life of oil and gas wells. This is because the presence of proppant allows fracturing fractures to remain open for a long time, thereby increasing oil and gas recovery.
Environmentally friendly products: Modern petroleum fracturing proppant is usually made of high-quality bauxite, coal and other raw materials. It has the characteristics of high temperature resistance, high pressure resistance, high strength, strong flow conductivity, and corrosion resistance. These properties allow proppant to operate in extreme conditions while minimizing environmental impact.
Adapt to different oil well design requirements: The particle size of the proppant must meet the design requirements of different oil wells, generally 0.4~0.8mm, and the roundness and sphericity are greater than 0.9. This particle size design allows the proppant to better adapt to the geometry of the oil well and provide more uniform support.
