Abstract
The invention discloses a kind of preparation methods of ceramsite sand, specific to the preparation method of the ceramsite sand containing cherty limestone, including grinding stirring, semi-finished product are pelletized, semi-finished product are dried, finished product is pelletized and etc..The ceramsite sand containing cherty limestone prepared using the preparation method of this ceramsite sand replaces high-cost bauxite using the cherty limestone and silica of addition low cost, to reach effectively save use cost on the basis of ensureing the indexs such as bulk density, apparent density, compression strength, acid solubility, sphericity, circularity and particle diameter distribution, while reducing the production cost of manufacturing enterprise；Compared with the similar product that cherty limestone is not added, the bulk density of this ceramsite sand containing cherty limestone can reduce 0.05~0.15g/cm3, and under equal conditions, this ceramsite sand containing cherty limestone can effectively save usage amount, therefore there is good economic benefit and social benefit.
Description
Technical field
It is specifically a kind of for the ceramsite sand containing cherty limestone the present invention relates to a kind of preparation method of ceramsite sand
Preparation method belongs to petroleum fracturing propping agent technical field.
Background technique
In petroleum gas deep mining, high clossing pressure deposits of low permeability makes Oil gas-containing rock layer after frac treatment
Split, oil gas collects from the channel of cracking initiation, at this time to keep after pressure break the crack that is formed to open, oil gas product energy
It is smooth to pass through, need to inject high-pressure solution rock base to be more than the pressure of formation fracture intensity, and then make rock around pit shaft
Layer generates cracking initiation one channel with high laminar flow ability, with petroleum fracturing propping agent (being called petroleum propping agent) in company with high
Pressure solution liquid enter Filling can play the role of in rock crack support crack, thus keep the high flow conductivity in channel,
Make the unimpeded increase yield of oil gas.
Currently used petroleum fracturing propping agent mainly has the composite particles of quartz sand, aluminium vanadine ceramsite sand and resin cladding
Deng, wherein using the ceramsite sand of aluminium vanadine haydite technique because it has the advantages that high density, corrosion-resistant, high temperature resistant, high voltage bearing, because
This is applied to exploitation of oil-gas field more and more widely.But bauxite is a kind of non-renewable mineral resources, is not only exploited
Production cost is higher, and can be as exploitation is using the increasingly depleted of resource is caused, and therefore, country also encourages manufacturing enterprise at present
Bauxite is replaced using other cheap raw material.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of preparation method of ceramsite sand, for the haydite containing cherty limestone
Sand can substantially reduce the manufacturing cost of ceramsite sand.
To achieve the above object, the preparation method of this ceramsite sand, for ceramsite sand include following mass percent at
Point: cast alumin(i)um ore 40~60%；Cherty limestone 10~25%；Silica 10~15%；Slag 5~10%；Clay 5~15%；
The preparation method is as follows:
A, uniform stir mixing will be carried out after above-mentioned raw materials separate compiling, and the surface for dischargeing raw material upon mixing is quiet
Electricity and stress；
B, the feeding of mixture continuous uniform is had to the facility for granulating of dry powder automatic humidification system and automatic weighing system
In pelletized to obtain semi-finished product；
C, according to the Particle size requirements of production plan, semi-finished product are sieved using drum sieve, and by screen out half at
Product are sent into dryer, are dried using rotary kiln waste heat to semi-finished product；
D, the qualified semi-finished product of drying are carried out screening out shedding part through vibrating screen screening, is then fed into rotary kiln and prepares
Finished product, and the temperature for the finished product produced is down to room temperature, that is, complete preparation flow.
It as a further improvement of the present invention, is 350~400 mesh by raw material separate compiling to partial size in step a.
As a further improvement of the present invention, step b requires the water content of semi-finished product to be no more than 5~7%.
As a further improvement of the present invention, step c requires the moisture content of semi-finished product being dried to 1~2%.
Compared with prior art, it is used using the ceramsite sand containing cherty limestone prepared by the preparation method of this ceramsite sand
Cherty limestone and the silica of low cost are added to replace high-cost bauxite, is ensureing that bulk density, view are close to reach
Effectively save use cost, drops simultaneously on the basis of the indexs such as degree, compression strength, acid solubility, sphericity, circularity and particle diameter distribution
The production cost of low manufacturing enterprise；Compared with the similar product that cherty limestone is not added, this ceramsite sand containing cherty limestone
Bulk density can reduce 0.05~0.15g/cm3, and under equal conditions, this ceramsite sand containing cherty limestone can
Effectively save usage amount, therefore there is good economic benefit and social benefit.
