Description
Technical field
Realized the present invention relates to a kind of pressure pulse in the fields such as oil drilling, mining, geological drilling steady
Determine the downhole tool of percussion.
Background technology
During drillng operation, drilling tool should carry out vertical direction operation, it is also necessary to horizontal or other direction operations.At drilling tool
When vertical direction operation, drill bit is located at same axis with upper drilling string, and drill bit is connected to drill string lower end and is drilled down into, drill bit energy
Enough receive enough the pressure of the drill and carry out drillng operation；And when drilling tool needs horizontal direction operation or deviates other directions of vertical direction
During operation, upper drilling string bottom needs to bend corresponding angle.Due to the reason such as horizontal segment length and bottom hole flushing effect difference, make
It is larger into frictional resistance suffered by drill string so that the pressure of the drill of well head can not be effectively transferred to drill bit, have to the drilling speed of drill bit very big
Influence, also can not just realize the directional drilling in later stage, the down-hole accidents such as bit freezing can be caused when serious, to horizontal well, extended reach well
And the safe construction of shallow-layer horizontal well etc. brings great hidden danger, increase the risk of underground work.
Most of axial vibration instruments need to produce periodic pressure pulse, such as mud motor by external impetus
And turbodrill.This kind of downhole tool can increase the expense of underground work and the complexity of downhole operations, therefore, it is necessary to by
One kind vibration speed enhancing apparatus, vibration is produced in the axial direction of drill string bottom, can alleviate backing pressure effect, effectively transmit the pressure of the drill,
To have the function that to improve drill bit rate of penetration and purpose.
The content of the invention
It is an object of the invention to：To overcome existing level well, extended reach well to creep into, frictional resistance is big, and well head the pressure of the drill can not be effective
Pass to drill bit insufficient and existing axial vibration instrument using effect it is undesirable the problem of, design a kind of pressure pulse and realize
The downhole tool of stable impact effect.
To achieve the above object, the technical solution adopted by the present invention is：The downhole tool by top connection, upper shell,
Inner cylinder, disk spring, hammer seat, lower housing shell, folded spring, branch sleeve, half point ring, from all directions set, anvil block, annular retaining ring, divide
Flow casing, piston, base, packing ring, square type sealing ring, abutment sleeve, valve, ring washer, O-ring seal composition, its feature
It is that top connection, upper shell, lower housing shell pass sequentially through screw thread with anvil block and be connected；Annular retaining ring be located at top connection and inner cylinder it
Between, and be equipped with through hole by inner cylinder axially position, annular retaining ring centre, be axially arranged with equally distributed 4 through holes；Diversion sleeve
Through hole is equipped among pipe, upper end passes through annular retaining ring intermediate throughholes just；Inner cylinder is between tapping sleeve and upper shell, and two
End is circumferentially with equally distributed 4 and crosses recirculation hole；Disk spring is located at the periphery of tapping sleeve, axially fixed by the hammer seat of lower section
Position, hammer seat pass through inner cylinder axially position；Using being threadedly coupled between piston and tapping sleeve, there is blind hole among piston, and
4 equally distributed shunting through holes are equipped with around blind hole；Using being threadedly coupled between base and piston, base is axially arranged with uniformly
4 of distribution cross recirculation hole；Valve upper end is circumferentially with equally distributed 4 and crosses recirculation hole；Abutment sleeve and folded spring position
Between lower housing shell and valve, axially position is carried out by branch sleeve upper end below folded spring, branch sleeve lower end is with folding
Spring is connected；Half point ring be located in the groove of anvil block, from all directions set is threadedly secured on lower housing shell, and be stuck in lower housing shell with
Between anvil block.
Compared with the prior art, its advantage is the present invention：(1) there is pressure pulse formula downhole tool can provide one
The periodical high-frequency axial impact force of a stabilization；(2) dither effectively overcomes the frictional resistance of lower drilling tool, realizes well head
Effective transmission of the pressure of the drill, improves rate of penetration, simultaneously as the vibration of instrument in itself, prevents drilling tool to be attached to the lower borehole wall for a long time
On, so as to avoid the generation of the down-hole accidents such as viscous card.
