Description
Technical field
The invention belongs to high-molecular compound technical field more particularly to a kind of fast-solving polyacrylamide and its preparation sides
Method.
Background technology
Polymer flooding is a kind of flooding method that water-soluble polymer solution is injected into oil reservoir, injects water by raising
Viscosity improves mobility ratio, and then effectively improves displacing phase affected area, reduces oil saturation to improve oil recovery factor.Note
Both sides important function will be generated by entering the polymer of oil reservoir：First, increase aqueous viscosity, second is that the delay because of polymer is drawn
Reservoir permeability is played to decline.Two aspects are coefficient the result is that mobility of the aqueous solution of polymer in oil reservoir is caused significantly to drop
It is low.Therefore, after polymer injection oil reservoir, two basic role mechanism will be generated：First, aqueous phase flow rate in control water flooded interval, changes
Kind water-oil mobility ratio improves the practical oil displacement efficiency of water flooded interval；Second is that fluid always flows in the water flooded interval of reduction high permeability
Degree, water-front advance velocity is poor between reducing height interval, adjusts intake profile, improves practical sweep efficiency.Since polymer improves
Water-oil mobility ratio controls seepage flow of the injection liquid in high permeability zone so that injection liquid is in the high and low permeable formation with more uniform
