Problems solved by technology

During the drilling process of the drilling tool and the rotating process of the drilling tool stabilizer, its centralizing belt will rub against the well wall, thereby causing damage to the drilling tool stabilizer, and the function of controlling the well deviation cannot be realized. Only by replacing the stabilizer, not only The cost is increased, and it is also very troublesome to disassemble, which consumes time and labor and affects drilling efficiency

Abstract

The invention discloses a segmented drilling tool stabilizer which comprises a strengthening shaft body (4) and a connecting shaft body (5), wherein a strengthening belt (3) is arranged on the outer end surface of the strengthening shaft body (4); an inner connector shaft (1) is arranged at one end of the strengthening shaft body (4); a thread is arranged in the inner connector shaft (1); a conical thread hole is formed in the other end of the strengthening shaft body (4); conical connectors are arranged at the two ends of the connecting shaft body (5); through holes are formed in the strengthening shaft body (4) and the connecting shaft body (5), and the strengthening shaft body (4) and the connecting shaft body (5) are integrally connected by matching the conical thread hole with the conical connectors. The drilling tool stabilizer designed by the invention is divided into two sections; when one section is worn and needs to replaced, only the damaged section needs to be replaced, and the other section also can be normally used, so that the materials are saved, the cost is reduced, and the service life is long.

Description

Technical field [0001] The invention relates to a petroleum drilling equipment, in particular to a segmented drilling tool stabilizer. Background technique [0002] Drilling stabilizer is the main tool used to control well deviation in oil field drilling engineering. During the drilling process of the drilling tool, the centering zone of the drilling tool stabilizer will friction with the borehole wall during the drilling process, which will damage the drilling tool stabilizer and cannot achieve the function of controlling the well deviation. Only replace the stabilizer. The cost increases, and the disassembly is troublesome, time-consuming and labor-intensive, which affects drilling efficiency. Summary of the invention [0003] The invention provides a segmented drill stabilizer, which divides the drill stabilizer into a two-section structure. When one of the sections is damaged, the other section can still be used without scrapping the entire drill stabilizer, thereby reducing ...
