Problems solved by technology

[0003] However, after a large number of on-site applications of the torsion punch tool, a prominent problem has been reflected: when the existing torsion punch tool is tripped, as long as the drilling fluid is circulated, the torsion punch tool will work and generate periodic torsional impact. Lacking the support and counteracting effect of the bottom rock, the tool is in the air strike state and the torsional impact force generated can only act on the tool shell and the connecting thread. The tool shell breaks and the connecting thread loosens and buckles occur many times, which is very easy to induce downhole damage. vicious accident

Embodiment 1

[0093] like figure 1 As shown, a kind of anti-empty type twisting tool is composed of an upper joint 1, a transmission joint 2, an upper housing 3, a semicircle card 4, a middle joint 5, a float valve 6, a lower housing 7, a spring 8, a valve seat 9, Diverter cover 10, commutator 11, pendulum 12, deflector 13, nozzle 14, nozzle base 15 and hammer seat 16;

[0094] like Figure 1 to Figure 10 As shown, the outer side of the lower end of the upper joint 1 passes through the transmission joint 2 and is in contact with the inner surface of the semicircular card 4. The middle part of the outer side of the upper joint 1 and the transmission joint 2 cooperate with the transmission through the regular octagonal transmission surface 17; The step surface of the upper joint 1 is in contact and fit, the lower end of the transmission joint 2 is connected with the upper housing 3 through threads; the inner wall surface of the upper housing 3 is in contact with the outer circular surface of...

Embodiment 2

[0108] like Figure 12 to Figure 15 As shown, the difference between Embodiment 2 and Embodiment 1 is that the transmission surface 17 is a regular hexagonal transmission surface, and the upper axial discharge passage 52 and the lower axial discharge passage 91 are waist-shaped discharge passages. The discharge channel 92 is a fan-shaped discharge channel.

[0109] In summary, the embodiment of the present invention relates to an anti-runaway twisting tool, which includes an upper joint, a transmission joint, an upper housing, a semicircle clamp, a middle joint, a float valve, a lower housing, a spring, a valve seat, and a shunt cover. , commutator, pendulum, deflector, nozzle, nozzle base and hammer seat; there is a transmission surface between the upper joint and the transmission joint, and the upper joint drives the semicircle card to move up and down inside the upper shell to realize the drilling fluid flow channel between on and off. The beneficial effect of the present...

Abstract

The invention discloses an anti-snap type twisting tool, which comprises an upper joint, a transmission joint, an upper housing, a semicircle clamp, a middle joint, a float valve, a lower housing, a spring, a valve seat, a shunt cover, a commutator, and a pendulum. Hammer, deflector, nozzle, nozzle base and hammer seat; there is a transmission surface between the upper joint and the transmission joint, and the upper joint drives the semicircle card to move up and down inside the upper shell to realize the opening and closing of the drilling fluid flow channels . The beneficial effect of the present invention is that it can generate periodic torsional impact force when working at the bottom of the well, improve the rock-breaking torque of the drill bit, improve the rock-breaking environment of the cutting teeth, and reduce the stick-slip vibration of the drill bit; when the drill is tripped, the torsional impact action can be stopped, It can prevent abnormal damage to the tool shell and connecting thread caused by air strike phenomenon.

Description

technical field [0001] The invention relates to the technical fields of oil and gas exploration, geological exploration and geothermal well development, in particular to an anti-airstrike type twisting tool. Background technique [0002] With the increasing proportion of deep wells and ultra-deep wells in the oil and gas exploration field, the problems of slow mechanical penetration rate, short stroke footage and high drill bit consumption during drilling construction have become increasingly prominent. For this reason, domestic and foreign petroleum practitioners are carrying out corresponding technology and equipment research, and various types of speed-up tools are constantly emerging, and the twisting tool is one of them. Torsional punching tools are mainly used to increase the rock-breaking torque of the drill bit, improve the rock-breaking environment of the cutting teeth, and reduce the stick-slip vibration of the drill bit, so as to protect the drill bit and increase...
