Abstract
The utility model relates to a large displacement well drilling matching tool, particularly relates to a large displacement well vibration tool which comprises an upper connector and a lower connector. A motor is mounted inside the upper connector. The motor, a cardan shaft, a transmission shaft, an accelerator, an eccentric shaft and the lower connector are connected in sequence. The large displacement well vibration tool reduces drill stem torque frictional resistance, and is favorable for downhole operation construction, and the large displacement well vibration tool overcomes the defects that resistance is large, drill stem friction torque is great, and delivery of torque is difficult when an existing large displacement well lifts a drill stem upwards and places the drill stem down.
Description
Technical field:
The utility model relates to a kind of extended reach well drilling well kit, particularly a kind of extended reach well vibratory tool.
Background technology:
At present, the hole angle of extended reach well is many more than 70 °, and is tiltedly dark large, gravitational effect is outstanding, thereby it is large to put when putting drill string resistance on causing, the drill string moment of friction is large, the transmitting torque difficulty, drill string and casing wear are serious, and the drill string limitation outstanding problem applies the pressure of the drill difficulty, bottomhole assembly easily produces flexing and causes self-locking, have a strong impact on normal production, greatly increased drilling period, wasted a large amount of man power and materials.
The utility model content:
The technical problems to be solved in the utility model provides a kind of extended reach well vibratory tool, and this instrument has realized reducing the drill string torque and friction, is conducive to Downhole Construction.Overcome that to put when putting drill string resistance on the existing extended reach well large, the drill string moment of friction is large, the deficiency of transmitting torque difficulty.
Technical solution adopted in the utility model is: a kind of extended reach well vibratory tool comprises top connection and lower contact; Motor is installed in the top connection, and motor, universal drive shaft, power transmission shaft, accelerator, eccentric shaft, lower contact connect in turn.
The beneficial effects of the utility model are: the utility model is because the mode that adopted motor, universal drive shaft, power transmission shaft, accelerator, eccentric shaft, lower contact to connect in turn, thereby has the function that reduces the drill string torque and friction, is conducive to Downhole Construction.
Description of drawings:
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Accompanying drawing is structural representation of the present utility model.
The specific embodiment:
As shown in drawings, a kind of extended reach well vibratory tool comprises top connection 1 and lower contact 7; Motor 2 is installed in the top connection 1, and motor 2, universal drive shaft 3, power transmission shaft 4, accelerator 5, eccentric shaft 6, lower contact 7 connect in turn.
During work, top connection 1 is connected with lower contact and is connected respectively drilling tool, motor 2 provides certain power to make instrument produce eccentric force, eccentric force changes direction by universal drive shaft 3, is transformed into the power of steady direction, through power transmission shaft 4 power is passed to accelerator 5, after the acceleration this power is passed to eccentric shaft 6, the eccentric force of the reinforcement that obtains thus passes to drilling tool by lower contact 7, reaches the effect of vibration, reduces torque and friction.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model being described and being not to be subject to the described technical scheme of the utility model embodiment, those of ordinary skill in the art is to be understood that, still can make amendment or be equal to replacement the utility model, to reach identical technique effect; Use needs as long as satisfy, all within protection domain of the present utility model.
