Core Functions And Features

1. High strength sleeve connection

o Precision-machined thread design complies with API standards, ensuring firm connection and excellent sealing of casing, suitable for high pressure (up to 10000psi) and complex well conditions.
o Supports multiple casing specifications (5″-13⅜″), suitable for the operation needs of conventional drill pipes and continuous oil pipes.

2. Multifunctional repair and salvage

• It can be combined with hydraulic disassembly and other tools to achieve rapid repair or salvage of casing fractures, reduce residual fragments of the wellbore and ensure safety of subsequent operations.
• Modular design supports rapid replacement of worn parts, reducing maintenance costs and downtime.

3. Corrosion resistance and long life

• It is made of chromium molybdenum steel or nickel-based alloy, which withstands high temperature (-30℃ to 150℃), acidic media and underground corrosion environment, and extends the service life of the tool.

4. Various specifications are available

• Depending on the drilling needs and collar sizes, Die Collar offers a variety of specifications and models for users to choose from to meet the needs of different drilling operations.

Product Type

The Die Collar products produced and sold by Huichi petro are diverse in specifications and can be adapted to drilling tools of different inner diameters. Common female cone specifications cover the internal hole size range of commonly used drill tools in oil fields, from smaller diameters to larger diameters, and there are corresponding models to choose from. At the same time, special specifications of female cones can be customized according to customers' special needs to meet the diverse oil field salvage operation needs.

1. Ordinary female cone: suitable for drilling tool salvage with conventional sizes and standard inner hole structures. Its design meets industry-wide standards and can cope with most general salvage operation scenarios. Its operation is relatively simple and is the first choice tool for daily oil field salvage operations.
2. Variable buckle female cone: When encountering drill holes of different specifications or special buckle types, the Variable buckle female cone plays a role. It can be adapted to a variety of different types of inner hole buckle types through a special variable buckle structure.
3. High-strength female cone: For some drilling tools that fall off in deep wells, ultra-deep wells or harsh geological conditions, this type of female cone is made of high-strength alloy steel, and has a special heat treatment process to make it stronger. Tensile, impact and wear resistance, can still reliably connect and salvage drill tools while withstanding huge tension and complex stresses.

Application Scenarios

Die Collar is widely used in marine and terrestrial oil drilling operations, especially in scenarios where drilling collars need to be fixed and supported, ensuring safe and smooth drilling operations. It is one of the indispensable and important components in oil drilling equipment.

• Casing repair: Quickly repair downhole casing deformation or breakage to restore the structural integrity of the wellbore.
• Salvage operation: Use salvage tools (such as shockers, grinding shoes) to remove foreign objects in the drilling hole.
• Discarded well sealing: Accurately cut and recycle the discarded casing to facilitate subsequent cement sealing.
