Oil Field Fluid Additive Polyacrylamide

Oil Field Fluid Additive Polyacrylamide is a polymer with a linear polymer molecular structure. After crosslinking, its structure is a block polymer structure, forming a three-dimensional network structure. Secondly, our water blocking mechanism is that the amide and carboxyl groups on the partially hydrolyzed polyacrylamide molecule affect the expansion degree and adsorption capacity of the molecular chain. Its blocking ability is manifested as fluid resistance, and the mechanism of decomposition and release of residual resistance is adsorption, trapping and physical blockage.

Feature

Oil Field Fluid Additive Polyacrylamide can change the seepage state of water in the formation to reduce the water production of the oilfield, maintain the energy of the formation, and enhance the final recovery rate. Secondly, we have the selectivity of oil-water permeability, the permeability of oil can be reduced by more than 10%, and the permeability of water can be reduced by more than 90%. Finally, our products can also add some resins to form a network of polymers that are compatible with each other, making them more resistant to temperate zones.

3、This product is soluble in water but not in oil. After being injected into the formation, it can limit the water output in the well without affecting the production of oil and gas. There is no need to measure the water source or the barrier section during treatment, and the treatment cost is low.

4、The use of oil field fluid additive polyacrylamide can also adjust the water absorption profile in the formation and block large pores, and good results have been achieved in practice.

5、This feature of selective water shutoff is not available in other water shutoff agents, and the appropriate relative molecular mass of polyacrylamide is usually selected according to the type of formation. For oil layers with good homogeneity and high average permeability, anionic polyacrylamide flocculant with a molecular weight of 8-12 million can be selected. For fractured oil layers with low base rock permeability or oil layers with large permeability changes, a molecular weight of 1600-1800 can be selected.
