around the pipe Cement covers the well wall or casing. Among the duties of cement against the well wall pipes, the following can be mentioned:
  • Protection against incoming forces and preventing pipe deterioration in the long term
  • Protecting the pipe from corrosion due to the presence of salty water
  • Protecting the penetration of water and various gases in the ground layers
  • Sealing parts of the well
    • < closing the well and preventing the exit of gas and other fluids

wall pipes have different types and in one well There may be several types Walling can be done. What is commonly done in wells The existing oil is as follows: Primary well wall pipe exploitation

primary wall pipes

Primary well wall pipe, which is also called conductor pipe, is one of the thickest well protection pipes and is used when the surface soils of the earth are so unstable that during drilling, due to corrosion and washing of the soil Unstable by mud drilling, small and large holes are created on the surface. These pipes have a length of 3 to 6 meters. Among the tasks of these pipes, the following can be mentioned:

  •    Guide the drilling fluid on the way back to the surface of the rig

Surface Wallpaper Tubes

Surface well casing pipes are the first part of casing that is placed deep enough to withstand the pressure caused by kicking different floors. Among the duties of this pipe, the following can be mentioned:

Intermediate well wall tubes for shallow wells It is not necessary, but these pipes are needed for deep wells. The functions of these well wall pipes are: in the well to prevent the abnormal pressure of the layers >

These pipes are used for walling for long-term tanks. This method is used for local walling for supplementary pipes, through which hydrocarbons are transferred from the tank to the outside. If the make-up pipes are leaking, the operation lining must be able to withstand the fluid pressure.
