Cementing Plug

Saigao Rubber plug used to separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance. Two types of cement plug 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 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.

A Cementing Plug is a separator that acts as a barrier between cement slurry and hydrocarbons present in a reservoir. This plug is made up of rubber and is also known as a wiper plug. The primary purpose of using the plug during cementing jobs is to prevent or reduce any contamination of hydrocarbons from cement slurry and maintain the predictable slurry performance.
