  • What is the oil displacement mechanism of polyacrylamide?
  • The oil displacement mechanism of polyacrylamide can be explained as follows: polyacrylamide can adsorb on the rock surface and adsorb water molecules, resulting in a decrease in the relative permeability of the water phase, so as to achieve the effect of oil washing.
  • What is micron-size polyacrylamide elastic microsphere?
  • Micron-size polyacrylamide elastic microsphere (MPEM) is a newly developed profile control and oil displacement agent for enhanced oil recovery in heterogeneous reservoirs. In this study, laboratory experiments were performed to characterize the viscoelastic properties of MPEMs in brine water.
  • How does polyacrylamide polymer flooding improve oil recovery?
  • Polyacrylamide polymer flooding mainly achieves the improvement of oil recovery by injecting high molecular weight polyacrylamide into the injection water, reducing the mobility ratio of the flooding phase, increasing the viscosity of the oil–water phase, and increasing the sweeping coefficient of the flooding.
  • What are the limitations of polyacrylamide?
  • Due to the relatively simple structure of common polyacrylamide, there are some limitations in production applications. Partially hydrolyzed polyacrylamide (HPAM) is widely used in actual tertiary oil recovery, and the degree of hydrolysis is generally between 25 % and 35 % .
