Description
Technical field
The present invention relates to oilfield chemistry articles for use field, particularly to a kind of silicate plugging agent for oil-well water plugging and using method thereof.
Background technology
In oilfield development process, due to formation heterogeneity, intrinsic fracture that prime stratum exists or produce on stream
Raw man-made fracture, and adopt by force that injection causes formation sand production, cement to run off in a large number, cement structure is destroyed, and makes stratum
Thief zone, macropore, broken up feature occur, thus cause well water to steeply rise, yield declines rapidly, and water processes
Workload strengthens, and oil reservoir produced degree is low watered-out well even occurs, and the blocking technology on this kind of stratum is always insoluble asks
Topic.
In prior art, the inorganic blocking agent of general employing or organic blocking agent block.The Cement Slurry that inorganic blocking agent is the most conventional.
During realizing the present invention, inventor finds that prior art at least there is problems in that organic blocking agent plugging strength not
Height or closure effect duration are short, and traditional cements blocking agent has low water-cement ratio, is easily generated sedimentation, and infusion is poor, the presetting period is short,
Easily operating tool string is blocked, bring certain limitation to site operation.
Summary of the invention
The purpose of the embodiment of the present invention is the defect for above-mentioned prior art, it is provided that the plugging strength of a kind of oilwell water shutoff is high,
The silicate plugging agent for oil-well water plugging that infusion is good.
The present invention adopts the technical scheme that to achieve these goals:
A kind of silicate plugging agent for oil-well water plugging, including the component of following weight percentage:
Common portland cement: 8-12%, SILICA FUME: 1-3%, waterglass: 0.3-0.7%, sodium lignin sulfonate: 0.01～0.03%,
Remaining is water.
Component including following weight percentage:
Common portland cement: 10%, SILICA FUME: 2%, waterglass: 0.5%, sodium lignin sulfonate: 0.02%, remaining is water.
The present invention also provides for the using method of a kind of silicate plugging agent for oil-well water plugging, comprises the following steps:
(1) in whipping process, successively waterglass, sodium lignin sulfonate and SILICA FUME are added according to proportioning the stirring installing water
In tank, it is uniformly mixing to obtain mixed liquor；
(2) then limit stirring, while add common portland cement in mixed liquor, i.e. forms silicate blocking agent base fluid；
(3) silicate blocking agent base fluid is injected in formation fracture.
The performance of each component of silicate blocking agent of the present invention:
(1) common portland cement
The cement that general civil engineering generally uses.
Common portland cement (GB175 1999, GB1344 1999 and GB12958 1999) includes silicate cement
Mud, Portland cement, portland slag cement, Portland pozzolana cement, Portland fly ash cement and comprehensive silicon
Acid salt cement.
Portland cement is mixed material, the hydraulicity glue that proper amount of gypsum is levigate to be made by Portland clinker, 6%～15%
Gel material, referred to as Portland cement (abbreviation ordinary cement), code name: P.O.
(2) SILICA FUME
The main chemical compositions of SILICA FUME is SiO2, content reaches 95%, and other also includes Fe2O3、Al2O3、CaO、K2O、Na2O、
MgO etc..SILICA FUME can be filled among portland cement space well, can play peptizaiton, can play again suspension and make
With, improve the mobility of serosity, strengthen the pump-conveying property of serosity, and the abrasion resistance after blocking agent final set can be improved.
(3) waterglass
Waterglass is sodium silicate solution state, and sodium silicate is colourless, the most colored transparent or half in the system with water as dispersant
Clear viscous shape liquid, can be obviously enhanced blocking agent intensity.Require modulus of water glass M=2.4～3.8 the most suitable.
(4) sodium lignin sulfonate
It is powdery low air-entraining performance retardation water reducing agent, belongs to anionic surface active substances, cement is had absorption and peptizaiton, adds
Enter the presetting period that can delay system on a small quantity.
The technical scheme that the embodiment of the present invention provides has the benefit that
The silicate blocking agent of the present invention has that the ratio of mud is high, infusion is good, presetting period length, intensity is high after final set, has preferably
The advantages such as water-fast erosion, physical property own to stratum is similar, can reach the construction requirement of oilwell water shutoff, its performance be suitable for non-all
Matter fractured reservoir.The present invention, by closure adjacent to oil well area crack, adjusts relation in interlayer or layer, reduces well water,
Improve oil production, for this type of reservoir waterflooding middle and late stage water and oil control, it is achieved long term stable production, explore new technological approaches.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below embodiment of the present invention is made the most detailed
Describe.
