Hydraulic fracturing technology is an effective technology ceramic proppant fields to increase production. The process is to use high-pressure pump on the ground, the high viscosity of the fracturing fluid to significantly exceed the absorptive capacity of the formation of the displacement is injected into the well at the bottom Biechu hypertension; when this pressure is greater than the near wellbore formation stress and when the tensile strength of the rock formations in the vicinity of the bottom layer can crack; continue to inject liquid with sand proppant, fracture extends forwardly and proppant filled fracture closure shut after filling proppant on the last crack with a geometry and conductivity in the vicinity of the bottom layer, to facilitate faster inflow of crude oil around the bottom of the well, to achieve the purpose of increasing production. As hydraulic fracturing proppant filling an important medium, which directly affects the capacity of the entire yield wells.ceramic proppants Therefore, the study of high performance oil proppant for oil yield is very necessary. Oil fracturing proppant * Major points of natural quartz sand, artificial ceramic proppant, resin-coated proppant (ie coated proppant) three categories, including coated proppant is divided into two coated sand and ceramic coating species.
