EXTERNAL CASING ATTACHMENTS

Cementing basket CK

Cementing Basket is used to create a platform for sedimentation of cement slurry filling outer annular
space outside a casing diameter 102, 114, 127, 140, 146, 168 and 178 mm.
During cement slurry squeezing a cementing plug goes through the inner hollow of the device and
disengages the early actuation protection. After receiving the “bump” signal and the check valve
leakage test the internal pressure is build-up to the actuation pressure of the device preset before the
device RIH. Shear bolts are destroyed and actuation starts. Petal shell is outstretched and touches
the hole wall thus constructing a base for sedimentation of cement slurry solid phase. Condensed
cement connecting strip is formed by itself on it thus preventing lowering of the cement slurry
column in the hole.
