Oilfield oil recovery and oil displacement agent anionic polyacrylamide
Oilfield oil recovery and oil displacement agent anionic polyacrylamide has a very important application in the tertiary oil recovery process of oil production. It has been fully utilized in large oil projects such as Daqing Oilfield, Xinjiang Oilfield, Shengli Oilfield, and Henan Oilfield. Every year, hundreds of thousands of tons of anionic polyacrylamide are used as displacing agents for oil production, adding more than 10,000 tons of oil to tertiary oil recovery in oil fields. The use of anionic polyacrylamide as an oil recovery and displacement agent is cost-effective, the technology is relatively mature, the cost is low, and the input-output ratio is low. It is very suitable for various large-scale domestic oil field projects.
Anionic polyacrylamide oil displacement mechanism
Anionic polyacrylamide amine has high water solubility and high molecular chain viscosity, which can improve the mobility ratio of the displacement fluid, increase the displacement efficiency and swept volume, and improve oil recovery. Yield.
, can reduce the oil-water mobility ratio of the petroleum layer, change the split flow curve, reduce the water content of the oil produced, and increase the oil production rate.
Anionic polyacrylamide amine improves the viscous fingering phenomenon of water flooding on the heterogeneous horizontal plane and improves the sweep efficiency in the plane range. In the vertical direction, the high viscosity characteristics of anionic polyacrylamide are used to cause subsequent water flooding from the high permeability layer into the low permeability layer, increasing the water absorption thickness and expanding the vertical sweep efficiency.
The anionic polyacrylamide molecular chain is hydrophilic. When the polymer passes through the pore medium, its adsorption and mechanical trapping effects are used to change the pore permeability, but it has little effect on the oil phase permeability, blocking Water does not block oil.
The anionic polyacrylamide polymer solution improves the viscoelasticity of the oil-water interface, making oil droplets or oil films easy to deform, and can pass through various pores to improve the microscopic oil displacement effect and increase oil recovery efficiency.
The molecular weight of anionic polyacrylamide used in oil field production is generally above 10,000 to achieve higher viscosity and better oil displacement effect.
