RESEARCH AND FIELD TESTING OF LIGNOSULFONATE FLOODING IN FAULT WEN 31

    Graphical Abstract
    • Abstract
  • Lignosulfonate(PS) is a new surfactant flooding appearing in recently.It extract and purify from waste liquid of paper made and have stabilization physical chemistry performance.It can reduce the viscosity of oil and the inter facial tension of oil-water.Flooding PS can enhanced oil recover.From laboratory testing,field testing and numerical simulation analysis,the oil displacement mechanism has been researched.The field experience and economic effect have obtained.
