    What is the meaning of well casing pipe in petroleum drilling?

    • admin diz:

      Well casing is Steel tubing that is threaded. Pin on bottom and box on top. Terminology: OCTG – oil country tubular goods, API – American petroleum institute
      The pipe is either steel plate that is welded or seamless tube that is formed.
      The well is drilled to a depth that is considered ‘as deep as possible’. Casing is then lowered into the well/hole and cemented in place. At that point you could drill out the casing and continue to go deeper with the casing holding the well bore stable above.

    what is the Application of API 5CT casing pipe?

    • admin diz:

      According by usage can be divided into the sleeve pipe, revestimento de superfície, casing and production casing.
      Each well depending on the depth of drilling and geological conditions, to use several layers of casing.
      Assim sendo, the casing consumption accounts for over 70% of all the oil well pipe.
      API 5CT casing pipe is used to support the oil and gas pipe wall, and to ensure the drilling process and the post-completion wells normal operation. After cementing casing to be used to go down, it different from tubing, drill pipe and can not be reused, a one-time consumable materials.
