  • Can hydrolyzed polyacrylamide be degraded?
  • For oil field applications, partially hydrolyzed polyacrylamide (HPAM) is the most widely used polymer. HPAM must maintain high viscosity to achieve good oil recovery. In reality, however, polymers can be severely degraded by shearing and heat in the underground environment. This phenomenon is studied in this paper.
  • What is partial hydrolyzed polyacrylamide (HPAM)?
  • ... Partially hydrolyzed polyacrylamide (HPAM) is a water-soluble polymer material used in oil fields [18,19]. It usually has a linear structure with high molecular weight and is obtained by partial hydrolysis of PAM or by copolymerization of sodium acrylate with acrylamide .
  • 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 % .
  • 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.
