Quartz sand plays an important role in the petroleum industry, mainly used
for fracturing operations in oil and gas extraction processes. Its main
functions are as follows:
1、 Proppant function
Quartz sand is one of the main materials for fracturing proppants. During the
fracturing process, operators inject high-pressure liquid into the oil and gas
reservoir, causing cracks in the rock formation. Subsequently, quartz sand is
used as a supporting agent to enter the cracks along with the liquid, filling
the cracks and maintaining their open state, preventing the rock formation from
closing and ensuring the smooth flow of oil and gas, thereby improving the
mining efficiency.
2、 Superior mechanical performance
Quartz sand has high hardness and compressive strength, which can withstand
the compressive force of high-pressure environments in reservoir formations, and
is not easily broken, thus maintaining its supporting effect. At the same time,
the chemical properties of quartz sand are stable and not easily reacted with
other chemicals in the oil and gas reservoir, ensuring the safety and
sustainability of operations.
3、 Strong selectivity in particle shape and size
Quartz sand used for hydraulic fracturing has good roundness and particle
size uniformity, which helps to form stable support structures in cracks. Quartz
sand of different particle sizes can be selected according to geological
conditions to achieve the best fracturing effect.
4、 Good economy and accessibility
Quartz sand is abundant in resources and relatively inexpensive, making it
one of the most commonly used fracturing support materials at present. Its
widespread application has reduced the cost of oil and gas extraction and
improved operational efficiency.
5、 Improve production capacity
The reasonable use of quartz sand during the fracturing process can
effectively increase the flow channels of oil and gas, and improve the
productivity of oil wells. Especially in the development of low-permeability oil
and gas reservoirs and unconventional oil and gas resources, the application of
quartz sand is particularly crucial.
In summary, the role of quartz sand in the petroleum industry is mainly
reflected in its performance advantages as a fracturing support agent. By
improving oil and gas flow conditions and increasing oil and gas field
production, it is an important material for efficient development of oil and gas
resources.
