A friction-reducing and drag-reducing torque clutch device and method thereof

Abstract

The invention discloses a friction decreasing and resistance reducing torque clutch device. The device comprises an upper joint (1), a lower joint (2), an appliance joint (4), a medium joint (5) and a pushing hydraulic cylinder body (6); the upper end part and the lower end part of a piston shaft (7) a respectively arranged n the medium joint (5) and the lower joint (2); a solenoid control valve (14) is arranged in the medium joint (5); a tooth embedded clutch is arranged in the lower joint (2); an outer tooth body (11) of the tooth embedded clutch is mounted at the lower end of the piston shaft (7); an electronic board (15) and a sensor (16) for receiving ground transmitted information are arranged in a sealing sleeve (3). The invention further discloses a method for decreasing friction and reducing resistance. The device and method have the beneficial effects that a drilling tool can be controlled to stably transmit torque or separate torque during drilling, which is beneficial for the reduction of frictional resistance and torque of a drilling column, release or preventing supporting pressure, as well as improving a drilling technology level of a large-inclination well, a horizontal well and a large-displacement well.

Description

technical field [0001] The invention relates to the technical field of oil drilling tools, in particular to a torque clutch device for reducing friction and drag and a method thereof. Background technique [0002] At present, in the process of exploration and development of oil and gas resources, drilling operations play a pivotal role. It is an important means to confirm and understand oil and gas structures, obtain geological data, and exploit oil and gas resources. The oil industry is a high-risk, capital-intensive and technology-intensive industry, and drilling costs account for 60% to 80% of the entire oil exploration and development cost, so a new drilling method and device are of great importance to the entire drilling project and even the oil industry. Impact. [0003] With the transformation of exploration and development to unconventional oil and gas resources and deep oil and gas resources, in order to increase the production and recovery of single wells and impr...

Problems solved by technology

At present, during the drilling process of highly deviated and horizontal wells, especially in the sliding drilling process using the curved shell mud motor, the drill string does not rotate, resulting in large torque and friction of the drill string, unclean wellbore, underpressure, etc. series of puzzles

[0004] At present, there are no reports or patents of this kind of downhole tools in foreign countries. There is a patent in the domestic Shengli Oilfield that is being publicized, but it transmits the control signal and applies the clutch engagement control force by changing the suspension weight. This method is not suitable for highly deviated wells. and horizontal wells, because in this case, the friction between the drill string and the well wall makes the axial movement and the transmission of axial force uncertain
