Problems solved by technology

Because it contains silicon carbide and other high-temperature fired foaming components, it is difficult to reuse it as a raw material for ceramic production
At present, although there are some reports on the production of light-weight insulation materials using the characteristics of high-temperature firing and foaming, they are less used because they do not have cost advantages compared with aerated concrete blocks.

Embodiment 1-10

[0031] With reference to Table 1, Table 1 is the formulation table of Examples 1-10.

[0032] Table 1

[0033]

[0034] Weigh the raw materials according to the formula components given in Table 1, then add 40% to 70% of the dry weight of water for ball milling to make a slurry with a fineness of 350 to 600 mesh; then spray dry the slurry and pass The granulator performs rolling granulation to make granular powder; then the granular powder is dried and sieved to obtain granular powder with a particle size of 20 mesh to 60 mesh (850 to 250 μm). Select 2.5 meters * 45 meters rotary kiln, calcining at 1100 DEG C ~ 1180 DEG C for 1-3 hours (the calcining time increases with the content of bauxite in the formula and lengthens, for example the calcining time of embodiment 1 is 1 hour, embodiment 1 The calcination time of 4 and 9 is 2.5 hours, and the calcination time of embodiment 5 is 3 hours.), to obtain the oil fracturing proppant. Its particle size is 20-60 mesh (850-250μm)...

Embodiment 11-12

[0040] In addition, in order to improve the flow conductivity of the prepared oil fracturing proppant, the present invention also provides Example 11 and Example 12.

[0041] Select the petroleum fracturing proppant particles prepared in the above example 3, and use a 20-ton ball mill to charge 40 to 45 tons of material for self-grinding and polishing (self-grinding and polishing does not add ball milling media such as balls, and uses the material itself for polishing) After 3 to 4 hours, after the ball is out, sieve and remove the throwing debris below 60 meshes, and then wrap the polished particles with a resin layer, specifically, use a drum mixer to disturb the polished particle powder During the process, atomized resin is sprayed, and the temperature in the drum mixer is kept in the range of 80-100°C through the hot air source at the other end. Wherein the resin selected in embodiment 11 is phenolic resin, and the resin selected in embodiment 12 is epoxy resin. The forme...

Abstract

The invention relates to a petroleum fracturing proppant and a preparation method thereof. The petroleum fracturing proppant is prepared from the following components by weight percent: 60-80% of bauxite, 10-30% of polished tile waste residues, 5-15% of iron ore slag, 0-5% of zirconia, 1.5-6% of aluminium sol or aluminium phosphate gel and 0.05-0.1% of adhesives. Tests show that the volume density of the petroleum fracturing proppant provided by the invention is 1.26-1.69g / cm<3>, the apparent density is 2.07-2.96g / cm<3>, and the crushing rate under the closure pressure of 86MPa is less than 5%. The petroleum fracturing proppant has the excellent characteristics of low and medium density, high strength and the like. Plenty of polished tile waste residues and iron ore slag are utilized in the raw materials, thus being favorable for reducing pollution and reducing the pressure of the waste residues of waste materials on the environment. Besides, the mineral components in the polished tile waste residues and the iron ore slag can serve as mineralizers in a calcining preparation process, thus reducing the production energy consumption while promoting the product performance.

Description

technical field [0001] The invention relates to a petroleum fracturing proppant and a manufacturing method thereof, in particular to a petroleum fracturing proppant produced by utilizing polished brick waste slag and iron ore slag and a manufacturing method thereof. Background technique [0002] Petroleum proppant is also called petroleum fracturing proppant. During oil and gas deep well mining, high closure pressure and low permeability deposits are treated by fracturing to crack the oil-gas-bearing rock formations, and oil and gas are collected from the channels formed by the fractures. At this time, fluids need to be injected into the rock base to overcome formation fractures Intensive pressure creates cracks in the rock formations around the wellbore, forming a channel with high-level flow capability. In order to keep the cracks formed after fracturing open, oil and gas products can pass through smoothly. The performance requirements of petroleum proppant: 1. The proppa...
