Abstract

The invention discloses a jet type torque-direction drag reduction oscillator, and relates to the technical field of the drilling technology. An impactor comprises a bi-stable jet flow element, an alternating pressure passageway, a torque cylinder, a torque hammer, a gland, a hollow double-nut connector and an upper connector. The gland, the bi-stable jet flow element, the alternating pressure passageway, the torque cylinder and the torque hammer are sequentially arranged in the hollow double-nut connector. The torque hammer is fixedly arranged in the hollow double-nut connector. The gland is fixedly arranged in the hollow double-nut connector. The first end of the hollow double-nut connector is connected with the upper connector. Through the corresponding structural design, the service life of a drill bit is prolonged, the rock breaking speed of the PDC drill bit is increased, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of drilling technology, in particular to a jet type torsional drag reducing oscillator. Background technique [0002] With the intensification of global energy tension, countries have put forward higher and higher requirements for energy extraction technology and energy extraction technology. In order to meet the needs of the development of oil and gas exploration, oil drilling work is mainly extended to deep and hard old formation blocks. In the process of deep well drilling and shallow drilling in many blocks in the west, the difficulty of hard formation drilling is very prominent. For example, hard strata have been encountered in the exploration and development drilling work in the Sulige area, the eastern Sichuan oilfield, and the northern oilfield in the Tarim Basin. This makes the Polycrystalline Diamond Compact (PDC) bit gradually become the mainstream of drilling. However, when the PDC bit is used ...
