Our Casing hanger is suitable for various
oil fields, and has safe and reliable work. The casing hanger mainly comprises
a slip and a mandrel type, wherein the slip hanger further comprises a WD type
slip hanger, a CG-21 type slip hanger and a CG-22 type slip hanger, wherein the
CG-29 type slip hanger can be further flexibly designed according to clients' requirements
and actual working behaviors.
CG-21 type slip hanger can be divided, is
manually triggered, is sealed by rubber, and is provided with an "II"
type packer seal ring, thereby achieving reliable sealing when the casing is in
a suspending or a disconnecting state, and the casing which is used on the skin
layer casing or the well cementing mud returning place is suitable for various
casing programs.
CG-22 type slip hanger is a ring-shaped
hanger consisting of a packer seal ring, a slip and a support bowl, and can be
separated. The casing is automatically sealed by the packer ring arranged on
the lower portion of the slip due to the gravity function of the casing column
after suspending the casing, the inclination of the casing can be reduced
through controlling friction force, the installation is convenient and
economic.
Compared with a normal hanger, the CG-29
type slip hanger has big bearing capacity and small inclination of casing. When
the upper slip is downwards moved and applies pressure to the packer seal ring,
the slip on the lower end of the hanger can be automatically geared and
controls the compression volume. Since the lower slip does not move along with
the casing, compression force cannot be generated as the normal conical slip.
