These are cementing plugs used in oilfield cementing operations. The red one is the bottom plug, and the black one is the top plug. They are core tools for isolating drilling fluid from cement slurry and cleaning the casing inner wall during cementing jobs.

Item Description
Product Name Cementing Plug (including Top Plug / Bottom Plug)
Functions 1. Isolate drilling fluid from cement slurry to prevent contamination of the cement slurry
2. Scrape residual drilling fluid off the casing inner wall and clean the borehole
3. Confirm cement slurry displacement and achieve "pressure bump" in cementing operations
Structural Features 1. Multi-lip rubber design for multi-stage sealing against the casing inner wall
2. The bottom plug has a breakable diaphragm, while the top plug is solid; they lock together to form a seal
3. Wear-resistant, oil-resistant, and high-temperature-resistant rubber outer layer, suitable for complex downhole conditions
Material Composition - Outer Layer: Oil/high-temperature-resistant rubber (e.g., NBR, FKM)
- Core: Phenolic resin or aluminum alloy (high strength, easily drillable)
Applicable Standards API Spec 10A / GB/T 43599-2023

Parameter Typical Range Notes
Applicable Casing Size 2-3/8" ~ 20" Customizable to customer casing sizes (e.g., 5", 7", 9-5/8", 13-3/8")
Temperature Rating 120°C ~ 200°C ≥150°C for standard service; higher ratings available for high-temperature wells
Pressure Rating 20MPa ~ 35MPa ≥20MPa for standard cementing plugs; up to 35MPa+ for high-pressure wells
Rubber Material NBR (Nitrile Butadiene Rubber) / FKM (Fluoroelastomer) NBR for oil and wear resistance; FKM for high-temperature and corrosive fluid applications
Core Material Phenolic Resin / Aluminum Alloy Phenolic resin is easily drillable; aluminum alloy offers higher strength
Working Differential Pressure ≥10MPa Ensures no leakage during displacement
Applicable Well Types Vertical, Deviated, Horizontal Anti-rotation plugs available for rotating liner cementing

Color Coding: Industry standard uses red for bottom plugs and black/blue for top plugs for quick field identification. 2. Working Sequence: The bottom plug is first released to isolate drilling fluid from cement slurry. Cement slurry is pumped, followed by the top plug to push the slurry. The two plugs "bump" at the casing shoe to complete displacement. 3. Drillability: The plug core is made of easily drillable material, which can be milled out after cementing without affecting subsequent operations.
