Description
Technical field
The invention belongs to petroleum fracturing propping agent technical fields, and in particular to a kind of porous petroleum fracturing propping agent of low cost
And preparation method thereof.
Background technology
It is well known that oil is the blood of industry, it is indispensable in people’s lives and industrial development.But with stone
The development of oily extraction industry, it is remaining at present it is mostly be hyposmosis, high clossing pressure oil field.In order to improve the exploitation in oil field effect
Rate, at present both at home and abroad extensively using hydraulic fracturing technology.The technology is exactly to generate the rock stratum under oil/gas well by fracturing operation
Crack, while petroleum propping agent with fracturing fluid is uniformly mixed and is pumped by formation fractures, play support rock seam, balance
The effect of rock stratum clossing pressure.In this way, the oil gas in rock stratum smooth can just flow out and be pooled to oil well bottom, taken out so as to facilitate
Go out.Therefore, petroleum propping agent plays a very important role in Low Permeability Oil/gas exploitation, is the key that hydraulic fracturing technology material
One of material.
Petroleum propping agent, support rock seam, water conservancy diversion oil gas ability, with its sphericity, bulk density, compression strength etc. because
It is known as pass.At present, the proppant of multidigit middle-high density produced both at home and abroad, but the proppant of these middle-high densities is easily in rock
Slabbing seam forms the accumulation of mound shape at port, so as to which the fracturing fluid for carrying proppant be hindered further to stitch depths flowing to rock, seriously
The production efficiency of oil gas is influenced, therefore, the development trend of petroleum propping agent is that development and application have appropriate intensity both at home and abroad at present
Low-density petroleum propping agent.
Petroleum fracturing propping agent production at present is aided with one or more of metal oxidations generally using alumine as primary raw material
Object does mineralizer, such as manganese oxide, calcium oxide, iron oxide, magnesia.But often relied in these raw materials superfine bauxite or
Level-one bauxite and manganese dioxide, these raw material production costs are higher, and process needs high temperature and pressure, which has limited
The further development of fracturing propping agents.
Porous petroleum fracturing propping agent is since with more open stomata, it is close not only to possess rather low volume
Degree and apparent density, and can accommodate antisludging agent and carry out oil well and underground pipeline slow down so as to play, even prevent and remove well
The effects that dirt improves oil well oil-producing efficiency, reduces oil-gas mining cost.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of porous petroleum fracturing propping agent of low cost and preparation method thereof,
The present invention is raw material using the montmorillonite of low cost, concave convex rod, expansible graphite, amine borate, bauxite etc., in relatively low temperature
Under be prepared petroleum fracturing propping agent, proppant has density small, and trepanning is high, resistant to breakage ability is strong and at low cost, the energy
Consume it is low, the characteristics of good economy performance.
The present invention provides a kind of porous petroleum fracturing propping agents of low cost, are prepared from the following components：
100 parts of bauxite
40-70 parts of montmorillonite
10-30 parts of concave convex rod
1-5 parts of expansible graphite
1-10 parts of amine borate
Aluminium content is 35wt%-75wt% in the bauxite.
The montmorillonite is selected from least one of sodium montmorillonite, calcium montmorillonite.
The concave convex rod is to come from naturally, the attapulgite clay prepared by simple processing.
The g/cm of the bulk density of the petroleum fracturing propping agent≤1.83, the g/ cm of apparent density≤3.03, 86MPa's
Under clossing pressure, percentage of damage≤5%.
The fracturing propping agents of the present invention substitute part bauxite with montmorillonite and concave convex rod, and montmorillonite and concave convex rod all contain
Abundant aluminium-magnesium silicate during being formed by a firing under high temperature addition, easily forms metal oxide, such as magnesia, aluminium oxide, oxygen
SiClx etc. is expanded at high temperature by expansible graphite, can these metal oxides be carried out trepanning, further be reduced oil
The density of fracturing propping agents prepares porous ore deposit；, on the other hand using amine borate, easily it is decomposed to form under amine borate high temperature
The generation very high boron carbide of hardness and strength is reacted at a high temperature of boron oxide, boron oxide and expansible graphite, boron carbide can
The intensity and hardness of the porous petroleum fracturing propping agent of preparation are significantly increased, further improves the anti-of petroleum fracturing propping agent
Breaking capacity.
The present invention also provides a kind of preparation method of the porous petroleum fracturing propping agent of low cost, specific implementation step is：
A) bauxite, montmorillonite, concave convex rod, expansible graphite, amine borate are mixed, is homogenized micronization processes, passed through
It is sieved after granulation, obtains mixture；
B) by step a）In the powder that mixes import in nodulizer, then powder is made to be revolved with nodulizer when sprinkling water thereto
Turn, after powder major part balling-up, then filter out semi-finished product of the grain size in 0.5-1 mm grain sizes；
C) by step b）In after prepared semi-finished product carry out preliminarily dried, be sent into 1100-1300 DEG C of high temperature furnace and forged
After burning 2-6 hours, product is obtained after supercooling.
Porous petroleum fracturing propping agent provided by the present invention, have good mode of appearance, relatively low bulk density and
Apparent density and higher resistant to breakage ability.
Compared with prior art, beneficial effects of the present invention are：
The present invention uses bauxite, montmorillonite, concave convex rod, expansible graphite and amine borate to be prepared for a kind of low cost for raw material
Porous petroleum fracturing propping agent, the present invention using cost is relatively low, the montmorillonite that derives from a wealth of sources, concave convex rod is raw materials, substitute part into
This higher bauxite can significantly reduce the cost of petroleum fracturing propping agent；Amine borate and expansible graphite are used as raw material,
Porous proppant can be prepared, and the boron oxide of amine borate decomposition generation can under hot conditions in calcination process
To react generation intensity and the higher boron carbide of hardness with expansible graphite, boron carbide can further enhance porous propping agent
