Product Features
1. Profile control and water shutoff is an important measure to reduce the moisture content in oil recovery and improve the ultimate recovery. Polymeric profile control and water shutoff agent is selective towards oil and water, preferentially entering high aquifers and adjusting water absorption profile in strata while plugging large outlet pore channels, thereby achieving the effect of water shutoff and oil increase.
2. The product can form high-viscosity and high-strength gel when reacting with organic crosslinking agent under the conditions of high temperature and high salinity, which can effectively plug the high permeability flow channel in the reservoir, promote the diversion of formation fluid, expand the water-flooding swept volume, reduce water cut, increase oil well production and improve development effect. The product has good solubility, wide application range of pH value and controllable gelation time. The gel produced by the reaction between the product and organic crosslinking agent is resistant to high temperature, salt, shear and hydrolysis, remaining stable and unbroken for 30 days at 130°C and salinity of 2.2×105mg/l.
