Nucleus-containing nutritional gel

The invention discloses nucleus-containing nutritional gel, which consists of water, partially-hydrolyzed polyacrylamide, a chromium acetate solution, thiourea, modified cellulose, corn steep powder, sodium nitrate and diammonium hydrogen phosphate. According to the nucleus-containing nutritional gel, the gel strength is enhanced through modified cellulose particles, the injection fluid wave and volume are enlarged by using an own functional blockage water current advantage channel, the physical property of crude oil and the property of an oil-water interface are improved through the biological functions and the biochemical functions of microorganisms, and the yield is increased. The nucleus-containing nutritional gel is applied to medium and high-water-content oil deposits in order to improve the exploitation effect.
