To drag-reduction effect, but complex structure and intensity requirement height are unfavorable for being arranged on the continuous pipe of pipe with small pipe diameter, while fatiguability damages the longevity
Life is short.The dynamic structure of current continuous pipe drilling well friction reducer generally promotes impact hammer complete using the open and close controlling drilling fluid of cavity
Into action, although this class formation can provide power, larger pressure drop can be produced.
Based on problem above, the present invention devises a kind of continuous pipe drilling well two-way oscillation friction reducer of turbine type, it is intended to solve
Certainly continuous pipe drilling well frictional resistance is big, easily stuck technical barrier.Oscillation ring is excited radially because of eccentric mass when being rotated by turbine wheel shaft
Vibration, rotarily drives rotary switch and adjusts runner aperture by turbine wheel shaft, excites water hammer effect so as to realize that axial vibration is acted on,
Reduce frictional resistance.Using the soft impulse of oscillation ring and the characteristics of thoroughly do not block drilling fluid, reduce the pressure drop of drilling fluid and carry
The life and reliability of high instrument.
The content of the invention
The invention provides a kind of continuous pipe drilling well two-way oscillation friction reducer of turbine type, the problem of solution is to reduce continuous

In order to achieve the above object, the present invention is adopted the following technical scheme that：
Technical scheme includes：Actuating unit, radial vibration mechanism, axial vibration mechanism and pipe nipple housing, its
It is characterised by, actuating unit is the turbine wheel shaft with multistage turbine nodule structure, is installed on by the supporting construction with bearing short
In section housing, it is ensured that turbine wheel shaft is rotated freely；Radial vibration mechanism is the oscillation ring with eccentric mass, turbine wheel shaft on turbine wheel shaft
Oscillation ring is because of eccentric mass generation radial vibration during rotation；Axial vibration mechanism is made up of turbine wheel shaft, rotary switch and vibrator,
Rotary switch is rotarily driven by turbine wheel shaft and adjusts runner aperture, excite water hammer effect so as to realize that axial vibration is acted on.Pipe nipple
Housing is used to install actuating unit, radial vibration mechanism and axial vibration mechanism, and provides and other downhole tools connections
Joint.
Such scheme is further included；
The oscillation ring adopts bolt mode, adjustable eccentric quality to change the radial direction amplitude and frequency of instrument with eccentric mass
Rate.The rotary switch and vibrator are respectively provided with two fan-shaped runners, and the fan-shaped runners area of rotary switch is less than vibrator
Fan-shaped runners area, it is ensured that still negotiable drilling fluid when opening of rotating switch is minimum.
Compared with existing friction reducer, the present invention has advantage as follows：(1) friction reducer produces radial vibration and axial direction
Two kinds of vibration modes of vibration, adapt to various Different Strata features and requirement, and drag-reduction effect is good；(2) engine of the friction reducer
Structure need not block drilling fluid circulation, and instrument pressure drop is reduced to the full extent；(3) axial vibration mechanism of the friction reducer is without rigidity
Impact, using water hammer effect exciting for vibration is completed, and improves the life and reliability of instrument.
