What is the role of cationic polyacrylamide in oilfield drilling?
1. Used as drilling fluid additive. Drilling fluid is used as a drilling mud performance modifier in oil extraction, and its function is to adjust the rheology of the drilling fluid, carry cuttings, lubricate the drill bit, and facilitate drilling. In addition, it can greatly reduce pipe sticking accidents, reduce equipment wear, and prevent lost circulation and collapse, making the well diameter regular.
2. Can be used as polymer flooding. Polymer flooding is to add a certain amount of polymer polyacrylamide to the injected water to increase the viscosity of the injected water and improve the oil-water mobility ratio. Due to the adsorption and trapping of polyacrylamide molecules by the oil layer, the permeability of high and medium permeability layers or high and medium water-flooded layers is reduced, and the seepage resistance of injected water is increased, making low permeability layers or low without water The water absorption of the flooded layer increases, which expands the sweeping range of the injected water on the oil layer plane and the water-flooded thickness of the oil layer in the vertical direction, thereby expanding the water-flooded volume and displacing the unused crude oil during water flooding to achieve enhanced oil recovery. rate purposes.
3. It can also be used as a water blocking agent. Polyacrylamide PAM chemical water blocking agent has selective effect on the permeability of oil and water. It reduces the permeability of oil less and reduces the permeability of water more. It can be used without crosslinking or with aluminum salt. , chromium salt, zirconium salt and other cross-linked gels can be used, and some resins can be added to form an interpenetrating polymer network (IPN) to make it have higher temperature resistance; the use of polyacrylamide PAM can also adjust the water absorption in the formation Profile and block large pores.
4. Used as a fracturing fluid additive. The fracturing process is an important stimulation measure for the development of tight formations in oilfields. Its function is to open channels in rocks and allow oil to flow through.
In oil field treatment, polyacrylamide can not only clean up oil stains in water, but also help companies improve oil recovery efficiency, so it has been widely used in oil field construction.
