Description
Technical field
The present invention relates to a kind of ceramsite propping agent and in particular to a kind of ultralow close ceramsite propping agent with Silicon stone as raw material and
Its preparation method.
Background technology
The low-density ceramic proppant substitute products as the type proppant such as quartz sand, not only have high intensity
The circularity sphericity become reconciled, more importantly being greatly improved of its flow conductivity, it is applied to the fracturing work of oil gas field for a long time, certainly
Also it is widely used in the fracturing work in shale gas field.Breakthrough with hydraulic fracturing technology and innovation, to extremely-low density haydite
The Unprecedented demands of proppant start to emerge, and are applied especially to the exploitation such as shale gas, coal bed gas.
But at present, the proppant product that a large amount of ceramsite propping agent manufacturers are produced is contained using 55～70% aluminum mostly
The big alumine with 5 of amount, alumina silica ratio, is Midst density product, intensity is generally relatively low.The low-density ceramic proppant of domestic production
The bauxite mine that the main raw material adopting is pure is joined a part of low aluminum clay and is partially sintered auxiliary agent, produce national standard and
The wider low density products of the coverage of domestic industry standard defined.
My company is existing to make full use of all of bauxite class resource using Silicon stone as producing ultra-low-density ceramic proppant
Many shortcomings, take full advantage of the advantage of China's silica resource, the high-volume low-grade ore to association or higher low of magazine content
Bauxite mine tailing is processed and is comprehensively utilized, and produces the higher ultralow close ceramsite propping agent of added value.At present, in industry still
Detailed standard is not formulated to ultralow close haydite.
Content of the invention
It is an object of the invention to provide a kind of ultralow close ceramsite propping agent with Silicon stone as raw material and preparation method thereof, low close
Degree, can meet the lighting of fracturing fluid well, reduce fracturing fluid and prepare cost, also reduce fracturing work to hardware device
Require；High intensity；Turbidity is low；Acid solubility is relatively low；And having excellent circularity and sphericity, preparation method is simply it is easy to grasp
Make.
The ultralow close ceramsite propping agent with Silicon stone as raw material for the present invention, raw material is consisted of by mass fraction：
Silicon stone 60-80 part, low-aluminium high red bauxite 5-30 part, limestone 1-7 part, Talcum 1-6 part, forsterite powder 1-7 part.
The ultralow close ceramsite propping agent with Silicon stone as raw material for the present invention, raw material by mass fraction preferably constitute for：
65 parts of Silicon stone, 20 parts of low-aluminium high red bauxite, 3 parts of limestone, 6 parts of Talcum, 6 parts of forsterite powder.
The present invention adds Silicon stone, and adds mineralizer, makes the quartz transition in Silicon stone during calcining be phosphorus quartz and cristobalite
Phase, the product density obtaining is lower, keeps certain intensity simultaneously, and Silicon stone is cheap, greatly reduces cost.
Described mineralizer is low-aluminium high red bauxite, limestone, Talcum and forsterite powder.
The preparation method of the ultralow close ceramsite propping agent with Silicon stone as raw material：
(1) raw material through broken, in broken after more in proportion dispensing, remove through 80-110 eye mesh screen after ball mill by wet process grinding
Remove bulky grain, be spray-dried and obtain powder grain material；
(2) after powder grain material forces balling-up, dry and be less than 5%wt to moisture, then between 18-30 mesh, sieve to obtain half one-tenth again
Product；
(3) semi-finished product are sintered into finished product, get product after being cooled to room temperature after 20-40 mesh sieve is divided into appropriate particle size.
After broken, the particle diameter of raw material is in below 0.056mm.
Grinding time is 1-2 hour.
Various raw materials are crushed to below 0.056mm.
Calcining heat is 1300～1500 DEG C, and calcination time is 3-5 hour.
Low bulk density of the present invention, reaches 1.30g/cm3Hereinafter, the proppant meeting current hydraulic fracturing job requirement is first
Want condition；Low apparent density, can reach 2.30g/cm3Hereinafter, the lighting of fracturing fluid can be met well, reduce fracturing fluid
Prepare cost, also reduce the requirement to hardware device for the fracturing work；Under 40MPa pressure, percentage of damage can reach less than 5.0%,
Under 52MPa pressure, percentage of damage can reach less than 10.0%；Turbidity is low, can reach below 60FTU, well below Standard：
Not higher than 100FTU；Acid solubility is relatively low, and on the premise of meeting other performances, also not higher than national standard requires：It is less than
5%；And have excellent circularity and sphericity, the sphericity of more than 0.85/0.85 can be reached.It is applied to shallow-layer oil well, sky
So whole process of the fracture support in gas and shale gas exploitation and passage offer.
With natural siliceous sand ratio the invention has the advantages that：
The present invention has low bulk density, meets the proppant most important condition of current hydraulic fracturing job requirement；Low regarding close
Degree, reduces fracturing fluid and prepares cost, also reduces the requirement to hardware device for the fracturing work；High intensity；Turbidity is low, and acid solubility is relatively
Low；And have excellent circularity and sphericity.Improve the oil and gas production in the unit interval, improve the length of service of Oil/gas Well；Suitable
Close shale gas, the exploitation of coal bed gas.Make full use of cheap Silicon stone and low bauxite resource of tailings, turn waste into wealth, improve domestic
The market structure of outer fracturing propping agents and present situation, mitigate that alumine demand is excessive and the too low pressure of quantity delivered.
