Wireline-Conveyed Thermit-Jet Cutting Tool (WTCT)
The Wireline-Conveyed Thermit-Jet Cutting Tool (WTCT) is a specialized tool designed for the oil and gas industry, specifically for cutting tubing, casing, and other downhole tubulars without the use of explosives.
This tool provides a safer, more efficient, and environmentally friendly alternative to traditional explosive cutting methods.
Description
Wireline-Conveyed Thermit-Jet Cutting Tool (WTCT)
Vigor Wireline-Conveyed Thermit-Jet Cutting Tool (WTCT) consists of an anchoring device and a combustor.
The anchoring device anchors the cutting tool to the inner wall of the pipe to be cut, preventing the tool from moving during the cutting process; the combustor produces a high-temperature and high-pressure molten metal fluid that scrubs and ablates the pipe, thus achieving the purpose of the cutting.
Safety option is considered, when the instrument cannot be unanchored during job, through the input of a 230mA current or lift the wireline more than 1.6T force to shear the shear pins and release the tool string.
Working Principles
Working Principles
1) Lower the Cutting Tool to the target position through wireline
2) Operate the ground control system to anchor it first
3) Ignite the combustor to cut the pipe column
4) Operate the ground control system to release the string from anchoring
5) Pull out the tool and do surface maintenance
Features
1. Safety
1)Eliminates the risks associated with handling, transporting, and using explosives.
2)Minimizes the potential for accidental detonations and associated hazards.
2. Efficiency
1)Provides precise, clean cuts with minimal damage to the surrounding tubulars.
2)Capable of operating in various well conditions, including high-pressure, high-temperature environments.
3. Versatility
1)Suitable for cutting a wide range of tubular materials and sizes.
2)Can be deployed in both vertical and deviated wells.
4. Operational Simplicity
1)Easy to deploy and operate with standard wireline or coiled tubing conveyance systems.
2)Requires minimal surface equipment and personnel, reducing overall operational costs

NOTE: Regarding the thermit cartridge quantity in tables
The thermit cartridge quantities listed in the tables are for reference when the external pressure on the thermit-jet cutting assembly is less than 10,000 psi. For external pressure between 10,000 and 15,000 psi, one additional cartridge is required.
