APPLICATION OF CASING MILLING SIDETRACKING TECHNOLOGY IN TUHA OILFIELD

    Graphical Abstract
    • Abstract
  • Tuha Oilfield is typical for its low pore pressure,low porosity and low permeability,and its structure is uneven.The water content goes up fast during the middle and later development period.These all severely influence the oil well life and oil recovery rate.To solve these problems,study and application of casing milling sidetracking technology was conducted based on the particular geology and reservoir characteristics in Tuha,and satisfactory results have been obtained.The associate technologies of casing milling sidetracking were illustrated,and the problems existed in field using were also presented.
