Ceramic proppants suit different design requirements for the well

Ceramic proppant particle size to meet the design requirements of the different wells, usually 0.4-0.8mm, roundness and sphericity of greater than 0.9, and particle uniformity, smooth surface, the haze high crush proppants vvalue should be less than 1000, in order to obtain the highest possible diversion capacity. 4, ceramic proppant particles under conditions of a temperature of 200 ℃, the fracturing fluid and the reservoir fluid is not a chemical effect, the solubility of the acid should be less than the maximum allowable value of 7%. Ceramic proppant oil, a key material of low permeability gas exploration fracturing oil and gas wells, in addition, in the construction industry is also widely used as a lightweight ceramic filler. Products resin coated ceramic proppant used in deep fracturing, it will be filled to its low permeability gap Iwaya deposits, high closed fracturing treatment, the oil and gas formations crack, crack is not due to play a supporting stress release and closed, thereby maintaining oil and gas high flow capacity, not only to increase oil and gas production, and can extend the service life of oil and gas wells.
