A connecting sleeve 7 is arranged between the bypass valve assembly 1 and the motor assembly, and the supercharging component is arranged in the connecting sleeve 7 and is in transmission connection with the motor assembly.

In this application, through installation pressure boost subassembly, on prior art's basis, improved the kinetic energy of motor assembly, finally improved the efficiency of creeping into, shortened required time.
The screw drilling tool is a power drilling tool which is most widely used in petroleum and geological drilling at present and comprises five parts, namely a bypass valve assembly 1, a motor assembly, a universal shaft assembly and a transmission shaft assembly. The screw drilling tool is usually matched with a mud pump truck for use, drilling fluid output by a mud pump enters a motor assembly through a bypass valve, a certain pressure difference is formed at an inlet and an outlet of the motor assembly to push a rotor 4 in the motor assembly to rotate, and therefore torque and rotating speed are transmitted to a drill bit through a universal shaft and a transmission shaft to carry out drilling operation.
In this embodiment, the bypass valve assembly 1 is located at the uppermost end of the screw drill and is an external interface of the screw drill, and the flow direction of the drilling fluid is controlled by two positions of bypass and direct connection. The lower end of a bypass valve assembly 1 of a traditional screw drill is connected with a motor assembly, the motor assembly converts pressure energy of slurry into rotary mechanical energy, the lower end of the motor assembly is connected with a cardan shaft assembly, the cardan shaft can convert plane planetary motion of the motor assembly into fixed shaft rotation, and then torque and rotating speed are transmitted to a transmission shaft assembly connected with the lower end.
In some embodiments of the high efficiency pulse screw drill provided herein, referring to fig. 1 and 2, the motor assembly comprises a stator and a rotor 4, and the rotor 4 is disposed coaxially with the stator.
At present, screw drilling tools are widely applied in the drilling process of petroleum and natural gas. The working principle of the screw drill is as follows: the mud pumped by the mud pump flows through the bypass valve and enters the motor, a certain pressure difference is formed between the inlet and the outlet of the motor, the motor rotor 4 is pushed to rotate, and the rotating speed and the torque are transmitted to the drill bit through the universal shaft and the transmission shaft, so that the drilling operation of converting the hydraulic pressure energy into the mechanical energy by the screw drilling tool is realized.
In the drilling operation process, the screw drilling tool drives the drill bit to cut rock stratum and needs certain energy, and in the process, when the output torque of the motor is smaller than the cutting torque needed by rock breaking, the phenomena of stick-slip vibration of the drill bit and braking of the motor can occur. The main performance is that in the drilling process, the drill bit suddenly accelerates or decelerates, the required drilling torque is unstable, the drilling footage of the drill bit is reduced, the instrument signal is unstable, and the drilling efficiency is reduced.
In order to solve the problems, the rotor 4 in the drilling fluid drilling device moves regularly in the stator, namely, the rotor 4 can rotate around the axis of the rotor 4 under the action of the drilling fluid, and the moving direction of the rotor 4 is fixed, so that the rotor 4 cannot suddenly impact the stator due to the change of the hydraulic pressure difference of the drilling fluid and the like, and the stability of the whole drilling process is ensured.
In some embodiments of the high-efficiency pulse screw drill provided in the present application, please refer to fig. 1 and 2, a limiting frame 6 is fixed on an inner wall of the connecting sleeve 7, and the limiting frame 6 is sleeved on the rotor 4 for enabling the rotor 4 to have only a degree of freedom of axial rotation around itself.
In order to realize the stable rotation of rotor 4 in the stator, the tip cover of rotor 4 is equipped with spacing 6 in this application, and spacing 6 self is fixed on the inner wall of adapter sleeve 7. The position of the limiting frame 6 relative to the connecting sleeve 7 is kept unchanged, and a plurality of liquid passing holes for the flowing of the drilling liquid are formed in the limiting frame 6. During practical application, drilling fluid at first flows through a plurality of liquid holes then contacts pressure boost subassembly, and the kinetic energy of self can rise under pressure boost subassembly's effect, and drilling fluid after the speed risees can strike rotor 4, because rotor 4 only has around self axial rotation's degree of freedom under spacing 6's effect, just makes rotor 4 stabilize in the stator internal rotation finally.
Since the relative positions of the rotor 4 and the stator do not change significantly, the net result is that more kinetic energy of the rotor 4 is transferred to the driveshaft assembly.

Under the effect of pressure boost subassembly, the drilling fluid that has certain impact force can strike rotor 4 to also can have certain effort to rotor 4 at the in-process cardan shaft assembly that drills, if rotor 4 does not have stable device that is used for spacingly, rotor 4 self pivoted state is difficult to guarantee.
Therefore, the end part of the rotor 4 is provided with a connecting shaft 5, the connecting shaft 5 and the rotor 4 are coaxially arranged, a limiting groove is formed in the circumferential direction of the connecting shaft 5, and the limiting groove is annular. The limiting frame 6 is clamped in the limiting groove. In practical applications, in order to avoid a large friction force between the limiting frame 6 and the connecting shaft 5, the bearing is firstly sleeved in the limiting groove, and then the limiting frame 6 is fixed on the outer ring of the bearing.
In order to ensure the connection stability of the limiting frame 6 and the connecting sleeve 7, the limiting frame 6 can be directly welded and fixed on the inner wall of the connecting sleeve 7, the limiting frame 6 needs to have certain structural strength, the surface area is reduced as much as possible, and the drilling fluid is prevented from having stronger resistance.

The impeller 9 rotates at a relatively high speed, but if a formation is encountered during drilling, the drill bit can only complete drilling in a longer time period as is conventional due to the lower drilling speed and the lower drilling efficiency of the drill bit caused by the higher hardness of the formation. As the rotational speed of the drill bit is reduced, the efficiency of energy conversion of the injected drilling fluid is low, i.e. only a small part of the kinetic and potential energy of the drilling fluid is transferred to the rotor 4.
Based on the above-mentioned problem, be provided with energy storage 3 between impeller 9 and rotor 4 in this application, impeller 9 can fill energy storage 3 at the beginning, when energy storage 3 stores certain energy and the effort to rotor 4 is greater than the resistance that rotor 4 received, and energy storage 3 can drive rotor 4 and rotate. When the speed of the rotor 4 reaches a certain value, the energy storage 3 and the rotor 4 will rotate in synchronism.
After the stratum hardness rises, the difficulty of drilling increases, the speed of corresponding drill bit also is the speed of rotor 4 and can reduce, the resistance that rotor 4 received increases, because impeller 9 is input and is rotated by the external energy source, impeller 9 rotational speed changes inconspicuously, more energy of impeller 9 can be stored to the accumulator in, because the energy crescent in the accumulator 3, the effort of accumulator 3 to rotor 4 can crescent, finally the rotational speed of rotor 4 can crescent under the effect of accumulator 3, also be through setting up accumulator 3, can improve rotor 4 drill bit pivoted speed when drilling the high hardness stratum, the effect of finally having improved and having crept.
In some embodiments of the high-efficiency pulse screw drill tool provided by the present application, please refer to fig. 1 and 2, a limit column 2 is fixed along an inner wall of the connection sleeve 7, and a head end of the energy storage 3 slides along an axial direction of the limit column 2 for adjusting a length of the energy storage 3 to change an elastic modulus of the energy storage 3.
The energy accumulator 3 is a flexible material part and has certain flexibility, and when parameters such as the hardness in the stratum are stable, the stable rotating speed of the transmission shaft assembly is ensured, so that the potential energy stored in the energy accumulator 3 needs to be reduced as much as possible. More importantly, the energy accumulator 3 has a certain loss of stored energy and released energy each time, and in the limit case, the stored energy in the energy accumulator 3 is 0, so that part of the kinetic energy of the impeller 9 is completely transferred to the rotor 4. When the formation hardness is increased, the traditional method is to improve the hydraulic pressure of the drilling fluid to drive the rotor 4 to rotate, but the energy loss is more, part of kinetic energy of the impeller 9 can be stored in the energy storage device 3 more at the moment, the acting force on the rotor 4 is larger correspondingly along with the increase of the potential energy of the energy storage device 3, and even if the drill bit drills into the formation, the drill bit can move to a certain extent under the action of the energy storage device 3, and the situation of blocking cannot occur.
In order to realize the adjustment of the energy stored in the energy storage device 3, the inner wall of the connecting sleeve 7 is provided with the limiting column 2, the length of the energy storage device 3 can be changed by sliding the head end of the energy storage device 3 along the limiting column 2, and the elastic modulus of the energy storage device 3 is changed after the length is changed.

In order to be able to adjust the length of the energy store 3, a certain force needs to be applied to the head end of the energy store 3, for which purpose an adjusting bracket 10 is first fixed to the impeller 9, without the adjusting bracket 10 affecting the rotation of the impeller 9. The impeller 9 is distributed between the adjusting frame 10 and the energy storage device 3, the adjusting frame 10 can drive the impeller 9 to move along the direction of the limiting column 2, and the energy storage device 3 can be pulled while the impeller 9 moves. And in order to drive the adjusting frame 10 to move up and down, the thread is rotatably arranged at the inner wall of the connecting sleeve 7, and the driving rod 8 is in transmission fit with the adjusting frame 10. Because spacing post 2 and alignment jig 10 sliding fit, alignment jig 10 can only slide along spacing post 2, has finally realized the change of alignment jig 10 position under the effect of actuating lever 8.
In some embodiments of the high-efficiency pulse screw drill provided in the present application, please refer to fig. 1, the limiting column 2 is welded and fixed on the inner wall of the connecting sleeve 7, and the limiting column 2 is arranged in parallel with the driving rod 8.
The purpose of the driving rod 8 is to slide the adjusting frame 10, and the sliding of the adjusting frame 10 will pull the energy storage device 3, and the up-and-down movement of the head end of the energy storage device 3 will change its elastic modulus, and when the energy storage device 3 is elongated, its elastic modulus will decrease, and the energy that the energy storage device 3 can store will decrease, but the transmission efficiency will increase. When the length of the energy storage 3 is reduced, the transmission efficiency is reduced as the energy stored in the energy storage 3 increases, but eventually the maximum force acting on the rotor 4 increases.
