Oil fracturing proppants-ceramic proppants
Oil proppant also called oil fracturing proppant.After oil and gas in the shale gas ( oil ) extraction,high closure pressure and low permeability ore deposit after fracturing treatment, make the oil cracked gas strata, gasoline from collecting in the crack formation of the channel, it requires fluid into the rock at the grass-roots level, to more than the strength of the formation fracture pressure, make the cracks around the wellbore rock strata, forming a channel with high flow ability, to maintain the formation of crack opening after fracturing, oil and gas products through smoothly.With oil proppant into the strata filling cracks in rock with high pressure solution, support gap is not because of the action of stress release and closed, so as to maintain a high diversion ability, make the oil and gas flow, increase production.
Ceramic proppant, high density, good sphericity, corrosion resistance, high temperature resistance, resistance to high pressure, cost at the same time be able to get good control, so more and more widely used by oil and gas fields.Practice has proved that using ceramic proppant fracturing of oil production of oil Wells can improve the 30-50%, are oil and natural gas of low permeability oil and gas well drilling, the construction of key materials, not only can increase oil and gas production, and more oil and gas Wells can extend the length of service.
