Aiming at the problem of the clamping and sliding vibration of the drill bit, a great deal of research is carried out in recent years at home and abroad, the torsion impact drilling technology and the matched special torsion impact tool are also designed and developed, namely, the special torsion impact tool is installed above the PDC drill bit and is used for providing periodic low-amplitude high-frequency torsion impact effect for the drill bit, the clamping and sliding vibration of the PDC drill bit can be greatly reduced or eliminated, but the field practice application finds that the existing torsion impact device has the following problems:
(1) The internal structure is complex, the number of connecting pieces and moving pieces is large, the abrasion and erosion are rapid, and the service life is reduced;
(2) The working pressure drop is high, and the ground machine pump equipment is in a high-load state for a long time, so that the safe and stable operation of the equipment is not facilitated;
(3) The appearance size is long, and the requirements of the directional well guiding drilling process cannot be completely met;
(4) The impact energy is small, although the impact frequency is high, the impact energy is small, and the effect of relieving the clamping and sliding vibration of the drill bit is limited;
The working principle of a torsion impact tool used in the existing torsion impact drilling technology is that hydraulic energy is utilized to drive an internal pendulum bob to swing reciprocally to generate an impact effect, namely, the hydraulic energy is converted into mechanical energy, so that impact parameters are closely related to performance parameters (displacement and pumping pressure) of a ground machine pump, and the adjustable range is limited, such as a torsion impact structure is related in a turbine torsion impact generator with the publication number of CN103670269A, under the premise of realizing large impact energy, an energy storage element, namely an impact frame, can store torque energy generated by a turbine in a interval between two impacts, and is completely released in the next impact, thereby improving the utilization rate of the torsion impact energy in the interval, but opposite, only internal liquid starts to flow to generate impact, the impact cannot be controlled in a self-adaptive manner, and the impact is continuously impacted all the time, so that the abrasion of movable parts in the torsion impact device is improved, and the service life of the device is shortened while the fault rate is improved;
Because of the limitation of the whole structure size, the internal impact module has smaller structural parameters, limited reciprocating swing space and small moment of inertia, namely small impact energy, and the technical advantages of reducing the slip vibration of the drill bit by torsional impact are realized through data investigation and field practice, the impact energy is increased, the impact frequency is reduced, and the moment of inertia of an internal mechanism is greatly improved, so that the design and development of a novel torque-increasing coupling device are urgently required, the high-amplitude low-frequency torsional impact energy can be generated, the pulsation torque of the drill bit is increased, the adverse effect of the slip vibration is eliminated or reduced, the service life of the drill bit is prolonged, the drilling rock breaking efficiency is greatly improved, the requirements of the conventional directional well drilling technology in China are also met, the pressure consumption is greatly reduced compared with the conventional torsional impact drilling technology, and the novel torque-increasing coupling device has the advantages of simple structure, long service life, convenience in maintenance, safety, high efficiency, low cost and high temperature resistance, and provides a powerful support for the efficient development of deep oil gas resources and mineral resources in China, and improves the comprehensive technical level and competitive power in the international drilling field in China;
