Oil proppant performance requirements

Oil proppant performance requirements:proppant conductivity sufficient compressive strength and wear resistance, can withstand strong pressure and friction during injection, and effectively support the artificial cracks;the relative density of the proppant particles to be low, to facilitate pumped downhole;resin coated proppant particles under conditions of a temperature of 200 degrees, with the fracturing fluid and the reservoir fluid is not a chemical effect, acid solubility of the maximum permissible value should be less than 7%.
Petroleum hydraulic fracturing proppant along with high-pressure solution is filled into the formation in rock fissures, cracks do not play a supporting closed due to stress release effect, thereby maintaining high conductivity, so that oil and gas flow, increase production.
