Abstract
The invention belongs to the technical field of artificial sintering proppants in the oil-gas well fracturing technology, and discloses a ceramsite proppant and a preparation method thereof. The ceramsite proppant is prepared from the following raw materials by weight percent: 85-95% of low-grade bauxite, 4-12% of cullet and 1-4% of clay. The raw materials are proportioned, mixed and ground, sprayed and granulated, and sintered for 30-80min at the temperature of 1300-1350 DEG C to obtain the ceramsite proppant. According to the invention, the ceramsite proppant is prepared by taking the low-grade bauxite as a main raw material and the cullet as a main addition agent, and the cullet can be purchased from the market with a very low price, so the direct production cost can be reduced by about **yuan/ton compared with the conventional method, the waste recovery of the cullet is realized and the environment is protected.
Description
Technical field
The invention belongs to oil, gas well fracturing technique artificial sintering proppant technology field, particularly a kind of ceramsite propping agent and preparation method thereof.
Background technology
The main raw material that ceramsite propping agent is oil, natural pressure splits adopts, it can provide the passage of hypertonicity for hydrocarbon flow, keeps high flow conductivity, greatly improves the output of oil, Sweet natural gas.At present, the ceramsite propping agent of China is main raw material mainly with bauxite greatly, add a small amount of fusing assistant mixed grinding such as manganese powder, potassium felspar sand, rhombspar and become powder mix, be atomized granulation again, formed by rotary kiln high-temperature firing, direct production cost is at 1150-1200 yuan/ton.Because each producer of Market competition is all at the ceramsite propping agent seeking production cost relative moderate.
Summary of the invention
The object of the present invention is to provide ceramsite propping agent of a kind of low cost and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of ceramsite propping agent, is made up of the raw material of following mass percent: low-grade bauxite 85-95%, glass cullet 4-12% and clay 1-4%.
In the present invention, in low-grade bauxite, in mass percentage, Al
2o
3< 65%, Fe
2o
3< 4.0%; Glass cullet refer to that the resident that reclaims in market is with waste materials such as waste plate glass, various cullet bottles.
Preparation method: prepare burden in proportion, mixed grinding, mist projection granulating, finally obtain finished product at 1300-1350 DEG C of sintering 30-80min.
Preferably, mixed grinding to the 400 order percent of pass thin powder mix that is greater than 98%.
Preferably, after granulation, particle after screening, drying, then sends to sintering.
The present invention adopts comparatively low-grade bauxite to be that main raw material and glass cullet prepare ceramsite propping agent as main additive; and glass cullet can be purchased from the market with very cheap price; its direct production cost is per ton compared with traditional method like this reduces about 100 yuan; and achieve the utilization of waste material of glass cullet, protect environment simultaneously.
