Description
Technical Field
The utility model belongs to the technical field of the drill bit, concretely relates to water conservancy pulse oscillation screw rod drilling tool.
Background
At present, a screw drilling tool used in the drilling engineering of petroleum and natural gas mainly has the functions of providing rock breaking power for a drill bit and adjusting a well track. Along with the exploitation and use of petroleum energy, international petroleum price fluctuates in recent years, China's exploitation also receives great influence, the exploitation wells of each large oil field are deepened and encrypted, old well sidetracking and horizontal well development are increased, so that difficulty is increased for exploitation, when directional operation is performed on some middle and short radius-of-curvature wells and horizontal wells, the underground drill string is seriously supported and pressed, the well drilling period is influenced, and the problem which needs to be solved in the exploitation process is solved.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a water conservancy pulse oscillation screw rod drilling tool to solve the problem that exists among the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a water conservancy pulse oscillation screw rod drilling tool, includes the oscillating system, pulse system, motor assembly, cardan shaft assembly and the transmission shaft assembly that connect gradually, its characterized in that: the pulse system includes alloy valve, static valve, prevents the cap that falls water, prevents rotary drum, a static valve section of thick bamboo, spring, inferior valve and epitheca, the static valve is fixed on the static valve section of thick bamboo, the front end of static valve section of thick bamboo and the keyway sliding fit of setting on preventing changeing a section of thick bamboo inner wall, the spring housing is in on the static valve section of thick bamboo, the ladder platform cooperation on the one end of spring and the inferior valve, the other end and the cooperation of the card platform of static valve section of thick bamboo front end, the alloy valve is fixed prevent falling on the cap and with static valve friction fit, the epitheca with inferior valve threaded connection, the inner wall of epitheca compresses tightly prevent the rotary drum, will prevent changeing a section of thick bamboo restriction between epitheca and inferior valve.
Compared with the prior art, the utility model, its beneficial effect is: the static valve is fixed on the static valve cylinder by the structure in order to avoid the situation in the background technology, the static valve cylinder and the anti-rotation cylinder are matched through the key slot, the spring is added behind the static valve cylinder, when two disc valves are abraded, the static valve cylinder can rebound under the action of the spring, the compensation effect is achieved, and the contact state is always kept.
Drawings
FIG. 1 is a schematic diagram of a pulse system according to the present invention;
fig. 2 is an overall view of the present invention.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings.
As shown in figures 1 and 2, the water conservancy pulse oscillation screw drill comprises an oscillation system 1, a pulse system 2, a motor assembly 3, a universal shaft assembly 4 and a transmission shaft assembly 5 which are connected in sequence, the pulse system comprises an alloy movable valve 6, a static valve 7, an anti-water-dropping cap 8, an anti-rotation barrel 9, a static valve barrel 10, a spring 11, a lower shell 12 and an upper shell 13, the static valve is fixed on the static valve cylinder, the front end of the static valve cylinder is in sliding fit with a key groove arranged on the inner wall of the anti-rotation cylinder, the spring is sleeved on the static valve cylinder, one end of the spring is matched with the step platform on the lower shell, the other end of the spring is matched with the clamping platform at the front end of the static valve cylinder, the alloy movable valve is fixed on the anti-water-dropping cap and is in friction fit with the static valve, the upper shell is in threaded connection with the lower shell, the inner wall of the upper shell compresses the anti-rotation cylinder, and the anti-rotation cylinder is limited between the upper shell and the lower shell. The static valve is fixed on the static valve barrel, the static valve barrel and the anti-rotation barrel are matched through the key slot, the spring is added behind the static valve barrel, when the two disk valves are abraded, the static valve barrel can be sprung up under the action of the spring, the compensation effect is achieved, and the contact state is kept all the time.
The drilling mud enters an upper oscillating system through a mud pump, passes through an inner hole of a mandrel of the oscillating system, enters a pulse system, enters a motor through a valve hole in the pulse system, and drives a motor rotor to rotate, while the rotor rotates, on one hand, the rotor rotates to drive a lower universal shaft and a transmission shaft to work, on the other hand, the rotor drives an upper anti-falling connecting rod to move, an alloy disk valve is arranged on the anti-falling connecting rod, and the alloy disk valve does periodic movement due to the fact that the movement of the rotor is planetary movement, so that periodic pressure pulses are generated, the pressure pulses act on the upper oscillating system, the oscillating system generates axial creeping movement, static friction force between a downhole drill string and a well wall is converted into dynamic friction force, and accordingly the pressure supporting condition of the drill string is prevented.
The utility model discloses not only have the power and the security of conventional screw rod drilling tool, can utilize screw rod drilling tool itself surplus energy moreover, provide pulse system to produce the required pulse pressure wave of axial oscillation, be that the drilling string can be smooth transmit the weight of drilling for the drill bit, improve and creep into efficiency, for other tools of the same kind, the utility model discloses simple structure, the energy consumption is little, and the effect is obvious, has not only improved well drilling efficiency, has saved the well drilling cycle moreover.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
