Polyacrylamide has been widely used in oilfield drilling, including oil field profile control, oil displacement agent, drilling fluid viscosifier, improving oil recovery and wastewater treatment of oilfield. The following is a summary of the basic principles of each applications. Specific usages will be elaborated in future sharing.

1. The oil field is cut and blocked: When the non-homogeneous condition is serious in the oil layer profile, the water flooding problem will be produced, and the oil layer shall be cut and water shutoff. The essence of profile control is to change the seepage state of water in the stratum, so as to reduce the water production, maintain the formation energy and improve the ultimate recovery rate of the oil field.
2. Do oil displacement agent : The oil displacement mechanism of the polymer is because the viscosity of the polymer solution is much larger than that of water, increasing the viscosity of the injection agent and reducing the water phase permeability, thus improving the oil recovery efficiency.
3. Drilling fluid viscosifier: Drilling fluid viscosifier can be used to improve the viscosity of drilling fluid in low solid drilling and control drilling fluid rheological properties, and can prevent lost circulation and collapse, increase the ability of drilling fluid and rock.
4. Improve the recovery of crude oil, mainly as three oil recovery agents and thickeners.
5. Oilfield sewage treatment: Polyacrylamide and its derivatives are important synthetic organic polymer flocculants. Compared with traditional inorganic flocculants, polyacrylamide has many advantages such as high variety, high flocculation efficiency and less sludge.
