1. Structure of API Cement Casing Plug Description


The cementing plugs manufactured in our company include top plug and bottom plug

1) Top and Bottom cementing pulg

2) Traditional and non-rotating type

3) High temperature and high pressure resistance

Description:

A rubber plug used to separate the cement slurry from other fluids, reducing contamination and maintaining predictable slurry performance. Two types of cementing 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. Top and bottom plug for cementing

Application:

The cementing plug is used to separate the cement slurry from the mud. It can prevent the mud from blending into the cement slurry to influence the cementing quality.

Structure:

There are two kinds of cementing plug: conventional cementing plug and special cementing plug.

Conventional cementing plug is divided into top plug and bottom plug. Special plug has top/middle/bottom plug used in two-stage cementing, drill pipe plug and hollow plug used in drilling liner cementing and composite plug used in composite casing.

  Top Plugs: The Top Cementing Plug is designed to exert continuous pressure on the casing wall. The core is made of special materials such as Plastic, Aluminum or Phenolic depending on the application and well conditions. The tapered base fits the cavity of the top plug initiating a positive seal. A solid rubber top plug is also available.

  Bottom Plugs: Like the Top Cementing Plug, the fins and tail section provide positive wiping action. Fins also serve as a seal while cementing. The core of the bottom plug also made of special materials such as Plastic, Aluminum or Phenolic depending on the application and well conditions. A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.

Top cement plug and bottom plug are always used together. Place bottom plug before injecting cement, and pump the scrape to clean the well-wall. After all is set, build the pressure of 2-4MPa till the rubber diaphragm is broken, and thus circulation is formed. Then inject the cement, place the top plug, pump, set the pressure, and well cementation comes to an end.
