Common market of the six types of petroleum proppant

        Oil  fracturing proppant  is a ceramic particle product with high fracture strength, mainly used for oil well supported in order to increase oil and gas production, an environmentally friendly product. This item is the use of various raw materials such as high alumina, sintered ceramic, a natural quartz sand, glass beads, metal balls, low intensity proppant substitute for oil and gas production with good results. Oil and gas deep mining, the high closure pressure low permeability deposits by fracturing treatment, the rock cracked hydrocarbon, oil and gas from the cracks formed in the channel pooling out.  Ceramic proppant  material with a solution into the formation along with the high-pressure filling fissures in the rock, play a supporting fissure is closed not because of the role of stress release, thereby maintaining high conductivity, so that gas flow, increase production.  Proppant  production are about six types:
       1 ultra low density proppant Coating: bulk density less than 1.20g.cm-3, depending on density of less than 2.0 g.cm-3, 69MPa broken rate is less than 3%.
       2 soft bonded sand proppant: can effectively address the formation damage caused by the movement resin sand layer of sand caused the problem again.
       3 antifriction type: Adding surface lubricants and special materials, the particle surface more smooth and eliminate static charge accumulation, thereby reducing wear and tear fracturing equipment and piping.
       4 water blocking type: coated surface material properties change, the particle surface impede water flow through the ability to accelerate the fluid through. At atmospheric pressure and the water is not passed, the oil can pass; under pressure, impeding the passage of water, accelerating the oil through.
        5 high permeability type: according to the gas adsorption characteristics, changing the particle surface coating performance, accelerating the gas passed.
       6 sand types: temperature and under pressure to close the liquid adhesive curing in the formation. The product can be used both for Fracturing Fracturing sand and gravel pack sand.
