APPLICATIONS OF SURFACE PRESSURE DRAWDOWN CURVES OF INJECTION WELLS IN PROFILE MODIFICATION USING CLAY

    Graphical Abstract
    • Abstract
  • The clay is a kins of cheap profile regulation agent.The surface pressure drawdown crue of injection well can be used to judge this agent is suitable or not,to determine the clay consumption as well as the Period of validity,and to contrast the different applying technologys of profile regulation agent.The concepts of pressure index,consumption index and hysteresis coefficient are introduced in the applications of drawdown curves.
