Description
Technical field
The present invention relates to a kind of high-strength ceramic proppant, simultaneously, also relate to a kind of preparation method of this ceramsite propping agent.
Background technology
Usually in the fracturing technology of oil, natural gas deep mining and ultra deep well, all can use propping agent,, keep high flow conductivity, improve the output of oil, gas for the circulation of hydrocarbon flow provides the passage of hypertonicity.In traditional oil production, generally adopt natural sand to cook propping agent, the propping agent that adopts other material such as clay, lanthanide metal oxide and Manganse Dioxide etc. to make for raw material is also arranged.The industry standard regulation of country: the antiacid corrodibility of ceramsite propping agent must be less than or equal to 5%, in use necessarily require ceramsite propping agent that higher antiacid corrodibility is arranged, this be because: contain acid mineral substance in the crude oil of underground mining, ceramsite propping agent soaks in sour environment, when oil gas constantly passes through, can carry out pickling to propping agent, make propping agent be dissolved into powdery, like this, not only do not have supporting role, also can stop up hydrocarbon flow, thereby make the lost of life of oil well.At present, there is following shortcoming in use in employed ceramsite propping agent: granular size is inhomogeneous, and compressive property is poor, easily broken; But topmost shortcoming is: antiacid corrodibility is low, is easy to cause forming local the obstruction, and the oil gas circulation is not smooth, can't more effectively support fracturing fracture, makes the permeability reduction in the crack, and oil yield rate is low, the waste resource.
Summary of the invention
The object of the present invention is to provide a kind of high-strength ceramic proppant,, improve antiacid corrodibility, prolong the life-span of oil well to improve its acid solubility.
