Nano-scale polymer microspheres for profile control and driving
Detailed Description
The importance of nanospheres in water flooding
The research and development condition of micro nano ball flooding is to solve the problem of low permeability area that water-soluble polymer cannot solve, Its main function is that after the nano microsphere is injected into the low permeability area, it will not block any pore roar or gap, and the pressure will not rise during the injection process. Moreover, the product can be used normally in the environment of high temperature and high salt, which has better effect in reducing the water phase permeability, so as to rationalize the liquid flow direction and expand water drive Micro sweep volume can increase oil production by water flooding.
The main characteristics of oil field specific nanospheres are as follows:
Nanospheres can effectively reduce the permeability of the high permeability part and effectively utilize the crude oil of the high and low permeability parts;
2. Nanospheres have cumulative effect and can be injected into multiple slugs;
3. It is insensitive to groundwater salinity and temperature, which is suitable for all kinds of water drive reservoirs;
4. Nanospheres can act on the deep part of the reservoir with relatively less dosage and lower economic cost;
5. Nanospheres have better stability and durability;
