FIELD: hydrocarbon exploration.
SUBSTANCE: group of inventions relates to the field of hydrocarbon production. The tubular assembly contains: the first part of the tool, while the first part of the tool contains the first thread and the second thread, the second part of the tool, while the second part of the tool contains an internal thread located at the second end of the second part of the tool, and a centering ring that is engaged with the second thread of the first part of the tool. In this case, the first thread and the second thread are located at the first end of the first part of the tool, while the first thread and the second thread have the opposite direction of the thread. Meanwhile, the second end of the second part of the tool is connected to the first end of the first part of the tool, while the internal thread is engaged with the first thread. The centering ring is located between the first part of the tool and the second part of the tool, while the alignment mark is located on the outer surface of the centering ring.
EFFECT: ensuring the alignment of parts of the equipment.
