Description
Technical field
The present invention relates to a kind of oil field chemical, specifically a kind of ionic liquid cement mortar early strength agent, it can accelerate cement
Hydration reaction speed at low temperature, can increase substantially the early strength of neat slurry, improve shaft building efficiency, cost-effective.
Background technology
Deepening continuously with petroleum natural gas exploration, oil gas drilling well cementation is more and more.Under cryogenic, one
Because hydration rate is slow, Slow setting time is long, easily there is oil gas water breakthrough in condensation process, affect Inter-zonal packing in aspect cement mortar.Another
Aspect, because strength of cement slower development, early strength are low, leads to increase well construction period, reduces oilfield prospecting developing economy effect
Benefit.This is accomplished by using low-temperature early strength agent, accelerates cement hydration rate under cryogenic, promotes Behavior of Hardened Cement Paste early strength
Development, reaches and can prevent oil gas water breakthrough, can shorten the purpose of well construction period so the early strength improving cement mortar becomes again
One critical restriction problem.
And traditional early strength antifreezing agent often contains inorganic villaumite, such as sodium chloride and nitrous acid or sulfate.China
Patent (ZL200710190542.X) discloses a kind of early strength agent of concrete water mud, it uses inorganic chlorinating sodium, sulphuric acid
The component such as salt and sodium nitrite.The use of these components, both not environmentally, can damage to workmen's body, also can be right
The durability of cement mortar has a negative impact.And Chinese patent (ZL03117563.5) then needs using special cementing concrete
On the basis of additional calcium chloride come to reach improve cementing fluid early strength purpose.Although the use containing villaumite can reach raising
The purpose of cement mortar early strength, but equally can bring the problem of steel reinforced concrete erosion and durability aspect it is impossible to apply
It is promoted in work.Chinese patent (ZL92103627.2) then reacts the product obtaining to carry using sucrose, sucrose with calcium oxide
The freeze proof and early epistasis energy of high cement slurry.But in the scheme of above-mentioned all disclosures or mandate, in anti-portland cement, on
State method then invalid.
With the demand of China's energy, Oil/gas Well, the dynamics of the engineering construction of coal mine constantly increase it is necessary to develop
With the early strength applying the antifreeze and early strong additive of new cement mortar to improve cement mortar, to improve efficiency of construction and speed
Degree.New strong additive of antifreeze morning also energy-saving and emission-reduction to be met and eco-friendly development tactics.
Goal of the invention
The present invention provide a kind of ionic liquid cement mortar early strength agent, using eco-friendly amine type ionic liquid compound and
Become, improve the early strength of cement mortar and the construction efficiency of Oil/gas Well.
The present invention specifically employed technical scheme comprise that：
A kind of ionic liquid cement mortar early strength agent, is characterized in that, be obtained by mixing by the raw material of following percentage by weight：
Ionic liquid 70-90%
Organoammonium ions polymer 5-15%
High-efficiency water-reducing agent of poly-carboxylic acid 5-15%
Above-mentioned three kinds of raw materials are mixed into 100%；
Wherein, the structural formula of ionic liquid is：
N=6～12 in formula；
Organoammonium ions polymer is acrylamide dimethyl diallyl ammonium chloride or allylamine trimethyl monoallyl
Ammonium chloride.
The effect of composite water-reducing agent of the present invention is to reduce cement consumption, and wherein, described high-efficiency water-reducing agent of poly-carboxylic acid is poly- horse
Come anhydride and poly glycol monomethyl ether polymerization and it is more preferable that the functional group mole of poly glycol monomethyl ether and cis-butenedioic anhydride
Than for 0.8～1:15.Through applicant's checking, the water reducer of this ratio makes pulp flowage good.
Preferably, the addition content of described ionic liquid cement mortar early strength agent is the 0.1%～5% of cement quality, especially
It is optimal with 1% 3%.
Wherein, described cement is portland cement, the particularly tricalcium silicate sulfate resistance silicon low with tricalcium aluminate content
Acid salt cement, the ratio of mud of suitable cement mortar is 0.30～0.50, is optimal particularly with 0.30～0.40.
Suitable use temperature, at 5 DEG C～35 DEG C, is especially optimal with 15 DEG C～25 DEG C.
The instillation process of the suitable cement mortar being strong additive of antifreeze morning using this ionic liquid can be pumping and stream
Pipe gravity conveys two ways.
Compared with prior art, the beneficial effects of the present invention is：
1) present invention does not use the sodium chloride that cement mortar later strength can be adversely affected；The present invention does not use cement
The widely used sodium nitrite of the early strong institute of slurry, thus avoid the health problem of the environment thereby resulting in and workmen.
2) present invention have concurrently early strong with antifreeze double effects, early strong raising for cementing fluid has high promotion and makees
With, and to 28 days intensity then no any detrimental effects.
3) volume of the present invention is low, and water-reducing rate is high, shrinks little, increases substantially early stage, the later strength of concrete.
4) this product chloride ion content is low, alkali content is low, is conducive to the durability of concrete.
5) ionic liquid of the present invention can significantly reduce the surface tension of cement mortar, and the zeta current potential of cement granules can be made to increase
Greatly, the electrical conductivity that improve the hydrated cementitious initial stage promotes the dissolving of each cement mineralses, accelerates entringite and the C of high silico-calcium ratio
The formation of S H gel, also can promote hydrated cementitious speed to accelerate simultaneously, make the formation of diaspore and quickly turn to cube crystal formation
Become, thus playing good rapid hardening effect.
