Description
Technical field
The present invention relates to field of ceramic material preparation, and in particular to a kind of proppant and preparation method thereof.
Background technology
Fracturing yield increasing is oil, the important new technology of natural gas low-permeability oil gas well exploitation volume increase.Proppant is then pressure break
The critical material of construction.Proppant is the natural sand or artificial high strength ceramics particle matched somebody with somebody with certain particle size and level.Proppant by
Fracturing fluid is brought into and is supported in the crack of fracturing stratum, so that oil gas effectively is imported into Oil/gas Well, increases substantially oil gas
Yield and extension oil well life-span.
Traditional ceramsite propping agent is pelletized using bauxite as raw material by powder, and sintering is formed, most widely used.Example
As CN1085288A discloses a kind of manufacture method of high-strength alumina supporting agent, major ingredient bauxite is fired and after crushing,
The auxiliary material that multi-component oxide and mild-clay constitute is added to grind and add water altogether or organic solvent mixed grind, then through loosening, into
Ball, screening, sintering, polishing and sieve again.CN101560381B discloses ceramsite propping agent and preparation method thereof, haydite support
Agent includes bauxite and mangano-manganic oxide, it is characterised in that the ceramsite propping agent includes aqueous organic binder bond, and the aluminium
