NITROGEN SOAKING TECHNOLOTY WITH SURFACTANT ASSISTANT

    Graphical Abstract
    • Abstract
  • The fashion of nitrogen injection includes nitrogen-water injection alternately, nitrogen-water injection with impulse and nitrogen soaking. Nitrogen soaking is simple and easier done, lower cost and quicker effect. The mechanism of nitrogen soaking is narrated briefly. Lab tests have been done to study the technology parameter of nitrogen soaking, and using surfactant to improve the effect of later stage. Field test shows nitrogen soaking technology with surfactant assistant is a feasible fashion of nitrogen injection.
