Compressive strength and wear resistance of petroleum fracturing
proppants
Performance requirements for petroleum proppants: 1. The proppant
must have sufficient compressive strength and abrasion resistance
to withstand the intense pressure and friction during injection and
effectively support the artificial fracture. 2. The proppant
particles must have a low relative density to facilitate downhole
pumping. 3. The proppant particles must not chemically react with
the fracturing fluid or reservoir fluid at a temperature of 200°C,
and the maximum allowable acid solubility must be less than 7%.
Currently, commonly used proppants include quartz sand, bauxite
ceramsite sand, and resin-coated composite particles. Quartz sand
is widely used due to its low cost and low density for easy
pumping. However, quartz sand has low base strength and poor
sphericity, which reduces fracture conductivity and makes it
unsuitable for deep wells with high closure pressures. Composite
particles made of resin-coated quartz sand offer improved
sphericity, stronger corrosion resistance, and better conductivity.
However, their short shelf life and high cost make them challenging
to commercialize in today's cost-conscious world. Ceramsite
proppants produced using the bauxite process offer high density,
excellent sphericity, corrosion resistance, high temperature
resistance, and high pressure resistance, all while maintaining
cost control. Consequently, they are increasingly being adopted in
oil and gas fields. Fracturing with ceramsite proppants has proven
to increase well production by 30-50% and extend the service life
of oil and gas wells. They are a key material for the development
and construction of low-permeability oil and gas wells, increasing
both production and service life.
Performance Requirements for Oil Proppants:
- Proppants must have sufficient compressive strength and abrasion
resistance to withstand high injection pressures and friction
forces, while effectively supporting artificial fractures.
- Proppants should have low relative density to facilitate pumping
into downhole locations.
- Proppant particles should not undergo chemical reactions with
fracturing fluids and reservoir fluids at temperatures up to 200
degrees Celsius, with a maximum allowable acid solubility of less
than 7%.
