Description
Technical field
The present invention relates to the preparation and application technical field of Organic-inorganic composite gel, and in particular to a kind of organic and inorganic
The preparation method of pluralgel water shutoff agent.
Background technology
Late period of oil field well water problem generally existing, not only have impact on oil recovery efficiency and oil quality, and
And huge economic losses are caused, need to carry out profile control and water plugging, especially with the oil field of waterflooding extraction commingling production mode, water blockoff
Operation was particularly important in the later stage of recovering the oil.More effectively method is that chemical plugging agent is injected oil well and note to administer well water
The water exit interval of well, reduces the water phase permeability of Thief zone water exit interval, has effectively blocked Thief zone, can force injection water
Less permeable layer in entrance, improves its sweep efficiency, improves reservoir recovery.With water-blocking operation more and more frequent, blocking agent
Consumption constantly increases.At present oil field with relatively broad be polymer organic water plugging profile control agent, because its price is higher, increased
Water-blocking operation cost, and there is no the feature of environmental protection.By contrast, silicic acid gel blocking agent have cheap, closure efficiency high with
And the advantages of good temperature resistance, salt resistance, the near wellbore zone profile control agent as the non-selective water shutoff agent and well of oil well is extensive
It is applied in oil development.But it is short to there is also gel time, the shortcomings of the hard brittleness of colloid is easily broken greatly, this all affects water blockoff
Efficiency.
