oil fracturing sand
1. Introduction
This oil fracturing sand is playing an significant role in the field of low-permeability fracturing exploration to increase and maintain production of oil and nature gas.
As a substitute of glass ball and metal globule, ceramic proppant has excellent performance due to reliable features of high temperature resistance, high strength, good conductivity, crush resistance and erosion resistance. It is also an environmentally friendly product. When in process, proppant transported by fluid is to fill the low permeability of the rock deposits in the crack, which creates a permeable channel. It allows the hydrocarbons flow more freely, thereby increasing both production rates and the amount of oil or gas actually recovered from the well. Many cases have been proved that by using ceramic proppant not only improve 30%-50% output of production, but also can extend the service life of wells.
