3. Application
1) SP and ASP flooding
According to the reservoir condition (temperature, Reservoir water hardness, Crude oil viscosity, and Reservoir heterogeneity) simulate the reservoir and polymer flooding data. Develop relative anionic polyacrylamide applied to different reservoir condition, through molecular design, simulation lab and field test. The product has good performance of temperature and salinity resistance, viscosity and shear resistance, and is applied in high temperature and high salinity reservoirs condition for EOR in ShengLi oilfield; effectively improve the oil recovery efficiency.
2)Water shut-off and profile control
As water shut-off and profile control agent, after injected into stratum, some of the group forms monomolecular layer absorption with formation trough hydrogen-bond reaction; the other group has strong affinity for water, in the effect of viscosity, residual resistance and viscoelastic, increase the water flow resistance, reaches blocking effect. The products will delay the gelatinization and reduce the gelatinization time, forms strong gel, high residual resistance coefficient, good performance of anti-salt and temperature, low volume, and will applied to different salinity for different mineral reservoir.
3)Drilling mud
The product has good viscosity and the ability of adjusting the flow pattern; it can maintain the drilling fluid viscosity in the hard conditions of high temperature, salt, calcium and magnesium ions, etc. It will inhibit shale hydration expansion, reduce bit wear, reduced the friction between the drill and mud cake, and has the effects of cross-linking plugging and shear dilution. It can greatly reduce sticking accidents, reduce equipment wear and tear, and prevent leakage and collapse. This product can be used compound with a various additives, suitable for all kinds of mud system
4. Attention
It's easy to moisture absorption. Stored in a cool、dry and ventilated environment.
