Products Description
Oil proppant is a material that plays an important role in oil and gas deep well exploration. It is mainly used for underground support in oil fields to increase the production of oil and natural gas. Here are some key performance characteristics of oil proppant:
1. High strength and wear resistance
Proppants need to have sufficient compressive strength and anti-wear capabilities, be able to withstand strong pressure and friction when injected, and effectively support artificial fractures. This ensures that the proppant can maintain its stability under extreme conditions, thereby maintaining the open state of fractures and improving oil and gas conductivity and production.
2. Low density and good pumpability
The relative density of the proppant particles should be low so that they can be easily pumped downhole. Low-density proppant can not only improve downhole work efficiency, but also reduce environmental impact. In addition, proppant with uniform particles and smooth surface can provide better pumpability and suspension, making the injection process smoother.
3. Specified particle size range
The particle size of proppant particles should meet the design requirements of different oil wells. Generally speaking, spherical particles with a particle size between 0.4 and 0.8 mm are most ideal because they can provide the best support effect and flow conductivity. Control of particle size is critical to ensure proppant effectiveness and durability.
4. Good chemical stability
The proppant should not chemically react with the fracturing fluid and reservoir fluid at high temperatures. This means that the proppant needs to have good chemical stability to prevent potential harmful effects and ensure that its performance remains unchanged over time.
5. Environmental protection characteristics
Petroleum fracturing proppant is an environmentally friendly product, and its use helps reduce negative impacts on the environment. The production process of proppant takes environmental factors into consideration. For example, some manufacturers use waste heat recovery technology to reduce energy consumption.
To sum up, the performance characteristics of petroleum fracturing proppant are mainly reflected in its high strength, low density, suitable particle size, excellent chemical stability and environmental protection characteristics. These properties enable proppant to play an important role in harsh working environments and contribute to the development of the oil and gas industry.
