STUDY AND APPLICATION OF TUBINGLESS PRODUCTION SYSTEM

    Graphical Abstract
    • Abstract
  • This paper gives an introduction for the construction and theory of tubingless production system,points out its advantages of eliminating the elastic deformation of tubing string,enhancing pump efficiency,lowering stress magnitude of rod string,improving working conditions,reducing individual-well invest and operation.The calculation results of practical example shows that system construction is reasonable and feasible,and it has a popularizing value.
