Description
Technical field
The present invention relates to oilfield exploitation blocking agents, specifically the stifled frozen glue of wide warm high salinity tune.
Background technique
Often there is well water during carrying out tertiary recovery in oil field.Well water can reduce original
Oil recovery, consume stratum energy, and aggravate equipment corrosion and fouling, while the crude oil water content produced increase so that after
Continuous dehydrating plant load aggravates, and underproof crude oil outlet causes environmental pollution, therefore how effective water blockoff is to improve oil recovering
The break-through point of rate.Common water shutoff agent has inorganic salts water shutoff agent, polymer gel class water shutoff agent, resinae water shutoff agent, foam
Profile-controlling and plugging agent etc., wherein polymer gel class water shutoff agent has selective water plugging effect, can effectively reduce in output crude oil
Moisture content.
Since the Regional Distribution of oil reservoir is wide, geological environment difference in place is larger, and the temperature difference of different oil reservoirs is larger: general
For the temperature of logical oil reservoir between 50-70 DEG C, a small number of reservoir temperatures are lower, can also have reservoir temperature higher, up to down to 30 DEG C
150 DEG C or more.Meanwhile the salinity of different oil reservoirs is also different.When using polymer gel class water shutoff agent, generally require to polymerize
Object frozen glue adapts to different temperature and salinity, but different temperature or different salinities to polymer gel at colloidality
It can be significant with stability influence.For the reservoir media of different temperatures or different salinities, there are many frozen glue to come out.
The patent of CN103409120A discloses Polymer nano intercalation composite blocking agent and preparation method thereof, this is compound
Blocking agent is compounded with organobentonite intercalation material and phenolic resin crosslinking agent or organic chrome cross linker by polyacrylamide and is formed,
It is mainly used for the oilwell water shutoff profile control that temperature range is 50~140 DEG C, can be used for the oil field that salinity is 0~40000mg/L
Water blockoff.The crosslinking agent phenolic resin and Organic Chromium stability that the blocking agent uses are poor, when especially temperature is higher (> 25 DEG C), easily
Rotten layering occurs, makes troubles to transport and site operation；And the blocking agent is only applicable to the Water in Water Shutoff in Oil Field of Low-salinity.
The patent of CN103614123A discloses a kind of polyethyleneimine frozen glue profile-controlling and plugging agent, by anion pp acyl
Amine 0.3~0.8%, crosslinking agent polyethyleneimine 0.2~0.5%, additive sodium sulfite, sodium hydrogensulfite, sodium thiosulfate
Or one kind or its any several mixture 0.3~0.8% of thiocarbamide, surplus is water, and the sum of each component is 100%, can be blocked
At 110 DEG C, the water flooding of NaCl salinity 50000mg/L, temperature tolerance is good, is not dehydrated within 120 days.Though the blocking agent can be used for mine
The higher water flooding of change degree, but thermal adaptability is poor.
Except upper frozen glue, there are many more patent (CN103980872A, CN103614123A, CN102807849B
Deng) different types of frozen glue is disclosed, but the frozen glue profile-controlling and plugging agent of these patent disclosures cannot meet wide temperature, high mine simultaneously
The needs of the oilfield exploitation profile control and water plugging of change degree.Therefore, the novel gel plugging agent of one kind is developed to exploitation different temperatures or mineralising
The oil reservoir of degree has great importance.
