ADVANTAGES AND MAIN FEATURES
Non-rotating cementing plugs are designed to decrease the drill out
times. Reinforced locking teeth are
built into the plugs, which lock together between the plug and the
float equipment to eliminate rotation
of the plug during drill out. The top cementing plug are latched to
the anti-rotational float collar.
Cementing plugs are used to remove the mud during cementing
operations.
Top cementing plugs and bottom cementing plugs are used in the
cementing process. The top and bottom
cementing plus general have different colors (bottom plugs are red
and top plugs are black) in
production for easy usage in operation.
The top cementing plug has a solid body that provides positive
indication of contact with
cementing floating collar and bottom plug through an increase in
pump pressure.
The bottom cementing plug with a hollow body is installed ahead of
the cement slurry to
minimize contamination by fluids inside the casing prior to
cementing.
Non-Rotary Cementing/Wiper Plugs (Polyurethane)
This plug is used to separate the cement slurry from other fluids,
reduce contamination, and maintain predictable slurry
performance and to clean various waste in the wall of the casing.
Two types of cementing plugs are typically used on a cementing
operation. The bottom plug is launched ahead of the cement slurry
to minimize contamination by fluids inside the casing prior to
cementing. A diaphragm in the plug body ruptures under 250~400psi
easily to allow the cement slurry to pass through after the plug
reaches the landing collar. The top plug has a solid body that
provides positive indication of contact with the landing collar and
bottom plug through an increase in pump pressure. This plug is
tested strictly every batch by pressure chambers at different
required pressure and temperature.
