FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to the oil and gas industry, in particular an extraction system for extracting a well component, such as a plug, from a downhole tubular metal structure. The system contains a tool column having longitudinal extension and containing a connecting tool made with the possibility of connecting to the well component, a power generator having the first part and the second part made with the possibility of connecting to the connecting tool and moving relatively to the first part to create axial force in the longitudinal extension, and an anchor section having at least one extendable element for anchoring the tool column. The system additionally contains a protective block surrounding the tool column and having at least one wall and at least one support surface made with the possibility of stopping in the narrowing. The extendable element rests against the wall of the protective block.
EFFECT: reliability of the extraction system is increased by ensuring that it can be disconnected in case of seizure.
