Description
Technical field
The present invention relates to a kind of oil field chemical, the early strong well agent of specifically a kind of low temperature oil-well.
Background technology
With deepening continuously for petroleum natural gas exploration, oil gas drilling well cementation is more and more.Under cryogenic, one
Aspect cement mortar easily occurs oil gas water breakthrough, influences Inter-zonal packing because hydration rate is slow, Slow setting time is long in condensation process.It is another
Aspect, because strength of cement slower development, early strength are low, causes increase well construction period, reduction oilfield prospecting developing economy effect
Benefit.This is accomplished by using low-temperature early strength agent, accelerates the hydration rate of cement under cryogenic, promotes Behavior of Hardened Cement Paste early strength
Development, oil gas water breakthrough can be prevented by reaching, can shorten the purpose of well construction period again so improving the early strength of cement mortar turns into
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) is open to authorize a kind of early strength agent of concrete water mud, but regrettably it uses nothing
The components such as machine sodium chloride, sulfate and natrium nitrosum.The use of these components, both not environmentally, can make to workmen's body
Into injury, the durability of cement mortar can also be had a negative impact.And Chinese patent (ZL00116214.4) then need to cement,
Yellow sand is adjusted with aggregate element.This is then substantially infeasible in Hydroelectric Project Construction, because above-mentioned material, which is first, supplies goods and materials, Party A
It is determined that can not be then adjusted to it later.And Chinese patent (ZL92103627.2) is then anti-using sucrose, sucrose and calcium oxide
The product that should be obtained improves the freeze proof and early epistasis energy of cement mortar.But in above-mentioned all disclosures or the scheme of mandate, for
Moderate resistance portland cement, the above method is 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 new cement mortar of application is antifreeze improves the early strength of cement mortar with early strong additive, to improve efficiency of construction and speed
Degree.New strong additive of antifreeze morning will also meet energy-saving and emission-reduction and environment-friendly development tactics.
The content of the invention
The present invention provides a kind of low temperature oil-well early strong well agent, to improve the early strength of cement mortar.
The technical scheme that specifically uses of the present invention is：
A kind of early strong well agent of low temperature oil-well, it is characterized in that, it is obtained by mixing by the raw material of following percentage by weight：
Ionic liquid 85-95%
High-efficiency water-reducing agent of poly-carboxylic acid 5-15%
Wherein, the structural formula of ionic liquid is：
The effect of composite water-reducing agent of the present invention is to reduce cement consumption, wherein, the high-efficiency water-reducing agent of poly-carboxylic acid is poly- horse
Come acid anhydrides and poly glycol monomethyl ether polymerization and obtain, it is more preferable that the function of poly glycol monomethyl ether and HPMA
Group's mol ratio is 0.8~1:15.Verified through applicant, the water reducer of the ratio makes pulp flowage good.
The present invention is as antifreeze accelerating component, and addition content is the 0.1%~10% of cement quality, especially with 1%-3%
To be optimal.
The ratio of mud of suitable cement mortar is 0.30~0.50, is optimal particularly with 0.30~0.40.
Suitable temperature in use, at 5 DEG C~35 DEG C, is especially optimal with 15 DEG C~25 DEG C.
Suitable cement is portland cement, particularly tricalcium silicate and the low anti-sulphate and silicate of tricalcium aluminate content
Cement.
It can be pumping and flow tube gravity for the instillation process of the cement mortar of strong additive of antifreeze morning to use the ionic liquid
Convey two ways.
Compared with prior art, the beneficial effects of the present invention are：
1) present invention is without using the sodium chloride that can be adversely affected to cement mortar later strength；The present invention is without using cement
The widely used natrium nitrosum of the early strong institute of slurry, so as to avoid the environment thereby resulted in and the health problem of workmen.
2) present invention is had concurrently early by force with antifreeze double effects, and early for cementing fluid is improved by force with high promotion work
With, and to 28 days intensity then without any detrimental effect.
3) volume of the present invention is low, and water-reducing rate is high, shrinks small, increases substantially early stage, the later strength of concrete.
4) ionic liquid of the invention can significantly reduce the surface tension of cement mortar, can increase the zeta current potentials of cement granules
Greatly, the electrical conductivity for improving hydrated cementitious initial stage promotes the dissolving of each cement minerals, accelerates the C- of entringite and high silico-calcium ratio
The formation of S-H gels, while can also promote hydrated cementitious speed to accelerate, makes the formation of diaspore and quickly turns to cube crystal formation
Become, so as to play good rapid hardening effect.
