Abstract
The invention discloses a high-strength ceramsite propping agent prepared by alumyte. The ceramsite propping agent is prepared by alumyte powder, manganese ore powder, ilmenite concentrate powder, bentonite and magnesium oxide. Raw alumyte ore is roasted into mature ore which is then crushed. Then the alumyte powder, the manganese ore powder, the ilmenite concentrate powder, the bentonite and the magnesium oxide are evenly mixed according to a certain proportion and then granulated. Semi-finished balls are obtained after drying. The semi-finished balls are positioned in a rotary kiln for sintering so as to obtain a crude product which undergoes the conventional treatment to obtain the ceramsite propping agent. Compared with the prior art, in the invention, the ilmenite concentrate powder is added in the propping agent, thereby being capable of reducing the sintering temperature and saving the energy; and the ilmenite concentrate powder can also enhance the compactness of an internal structure, promote the formation of crystalling phases (mullite, corundum phase), improve the strength of the propping agent, and be good for enhancing the toughness, reducing the breakage rate and maintaining high flow guide capability. The invention adopts an improved coal gas heat-supplying rotary kiln mode to sinter the semi-finished product so that the obtained propping agent not only has stable quality and high sphericity but also has uniform color brightness.
Description
Technical field
The present invention relates to the petroleum propping agent technical field, particularly relate to a kind of high-strength ceramic proppant and preparation method thereof.
Background technology
To oil, gas extraction, oil, the Natural gas extraction degree of depth are constantly deepened through many decades, formation closure pressure is also increasing, and penetrating quality reduces.For the circulation of giving hydrocarbon flow provides the passage of hypertonicity, keep high flow conductivity, improve the output of oil, gas, adopting with the propping agent usually is the fracturing technology of main raw.Yet, the propping agent product of domestic most manufacturer production causes the dependency of import propping agent product very big because cause for quality makes its product can not be used for the deep-seated oil gas well, but costing an arm and a leg of import propping agent, restriction China is to the oil-gas mining of deep-seated oil gas well.
Publication number is that 1179907 Chinese patent " manufacture method of high-strength ceramic proppant " is to be main raw material with ripe bauxite, wilkinite, and lanthanide metal oxide, Manganse Dioxide, magnesium oxide are that auxiliary material is produced ceramsite propping agent according to a certain ratio.The deficiency of this technology is to cost an arm and a leg the lanthanide metal oxide shortage of resources that adopts, has increased product cost, and secondly, lanthanide metal oxide and bauxitic clay major ingredient pyroreaction associativity are bad, easily cause unstable product quality, and quality fluctuation is big.
At present, domestic most of producer adopts tunnel kiln sintering technology, rotary kiln sintered technology is more advanced technology, what Chinese patent application CN02112746 " a kind of Selid propping agent and manufacture method " used is the rotary kiln sintered technology that Sweet natural gas acts as a fuel, its shortcoming is that Sweet natural gas is done fuel, the cost height, particularly especially outstanding in the abundant Guizhou province of the coal resources main raw material bauxite resource used with making ceramsite propping agent.
Summary of the invention
Technical problem to be solved by this invention provides a kind of high-strength ceramic proppant and preparation method thereof, and this proppant strength height, percentage of damage are low, steady quality, degree of sphericity height, color and luster are evenly shinny etc.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
According to listed as parts by weight, high-strength ceramic proppant of the present invention is to be prepared from for 1～5 part by 100 parts of bauxite powders, 2～20 parts in manganese ore powder, 0.5～3 part in ilmenite concentrate powder, 3～10 parts of wilkinites and magnesium oxide.
Preferably, above-mentioned high-strength ceramic proppant is to be prepared from for 2～4 parts by 100 parts of bauxite powders, 8～15 parts in manganese ore powder, 1～2 part in ilmenite concentrate powder, 5～8 parts of wilkinites and magnesium oxide.
Al in the used bauxite in the aforementioned high-strength ceramic proppant
2O
3Content be 85% or more than.
TiO in the used ilmenite concentrate powder in the aforementioned high-strength ceramic proppant
2Content be 45% or more than.
The preparation method of aforementioned high-strength ceramic proppant: get the ripe ore deposit of bauxite rawore roasting, pulverize, in proportion bauxite powder, manganese ore powder, ilmenite concentrate powder, wilkinite and magnesium oxide are mixed, granulate, the dry work in-process ball that gets places sintering in the rotary kiln with the work in-process ball, gets thick product, thick product is handled through routine, promptly.
The sintering temperature of rotary kiln is that 1200～1450 ℃, sintering time 15～120min, rotating speed are 1～2r/min among the above-mentioned preparation method.Under the situation that no ilmenite concentrate powder adds, obtain the high-strength ceramic proppant product of equal in quality, sintering temperature needs more than 1700 ℃, therefore, adds the ilmenite concentrate powder and can reduce sintering temperature, save energy.
Rotary kiln among the aforementioned preparation method adopts the producer gas generator heat supply.The raw coal of producer gas generator adopts hard coal, and pulverized anthracite is broken into 3～5cm size, through with the air thorough mixing after form gas mixture, with gas mixture ejection burning at a high speed in rotary kiln, realization is to the high temperature sintering of product.Coal price is cheap, and particularly there is realistic meaning in the few area of the many gas of the such coal in object Guizhou, simultaneously, coal gas is compared with Sweet natural gas, and the solia particle in the combustion flame can improve radiative transfer, helps improving device heat efficiency, improve equipment capacity, reduce production costs.
The inwall of the rotary kiln among the aforementioned preparation method is to be the refractory brick of base-material with prescription of the present invention.Overcome that refractory brick in traditional rotary kiln falls slag and the defective that causes unstable product quality and irregular colour one.
Compared with prior art, the present invention adds the ilmenite concentrate powder in propping agent, can reduce sintering temperature, save energy, the ilmenite concentrate powder can also strengthen the density of internal structure, promotes crystalline phase (mullite, corundum phase) to form, improve the intensity of propping agent, also help enhancing toughness, reduce percentage of damage, keep high flow conductivity.The present invention adopts improved gas heating rotary kiln that work in-process are carried out sintering, not only makes propping agent steady quality, the degree of sphericity height made, and the shinny homogeneous of color and luster.
