Below in conjunction with the accompanying drawings and the preferred embodiment embodiment that the present invention will be described in detail.
In the description of the present invention, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown, is for only for ease of the description present invention and simplifies description, rather than instruction or the dress for implying meaning
Put or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to limit of the invention
System.
A kind of hydraulic blow system, its structure mainly by：Impact pipe nipple assembly 1 and hydraulic pulsetor assembly 2 form；
As shown in Figure 1, the impact pipe nipple assembly mainly by：Drive mandrel 11, top connection 12, sealing silk plug 13, transmission

111st, crossover sub 112, dustband 113, BA sealing rings 114, guidance tape 115, BA sealing rings 116, BA sealing rings 117 are formed；
The dustband, BA circles, guidance tape put into top connection successively, and the drive mandrel is connected with top connection one end, it is described on connect
The other end of head is connected with the drive housing, and the drive mandrel is connected with anti-lost nut, and the drive mandrel and disc spring connect
Connect, the drive mandrel is connected with mandrel connector, and the drive housing is connected with middle sleeve, the mandrel connector and dummy piston
Connection, the middle sleeve are connected with whitewashing housing, and the mandrel connector is connected with balance pressure cap, and the whitewashing housing and conversion connect
Head connection；
As shown in Fig. 2, the hydraulic pulsetor assembly 2 includes：Top connection 21, spacing excess flow valve 22, metal motor stator
23rd, rotor 24, integral type move the quiet valve 26 of valve 25, integral type, lower contact 27, O-ring seals 28, O-ring seals 29, O-shaped sealing
Circle 210, the O-ring seals put into top connection, the quiet valve of integral type, in lower contact successively；The spacing excess flow valve and metal horse
Up to connection, the top connection is connected with metal motor, and the rotor moves valve with integral type and is connected, and the integral type moves valve
It is connected with rotor with metal motor, the quiet valve of the integral type is connected with lower contact；The quiet valve of the integral type and lower contact with
Metal motor connects；
Operation principle：
The power section of hydraulic blow system is that have one 2:1 metal motor composition, the lower end of motor rotor fixes one
A moushroom valve, so fluid drives rotor to rotate when passing through power section, since the characteristic end of motor is in one plane reciprocal
Movement, therefore it is referred to as dynamic valve.
What is be connected with power section is that integral type moves valve, and critical piece is exactly that an integral type moves valve and the quiet valve of integral type is tight
Close fit, since the rotation of rotor causes two valve blocks to be staggered and overlap, be staggered and overlap result in upstream pressure become
Change, the sectional area (maximum and minimum value) that periodic relative motion causes fluid to flow through instrument periodically changes.
As shown in figure 3, when two moushroom valves at least overlap, due to fluid by the sectional area of instrument to be minimum, so passing through
A maximum pressure drop is just produced after instrument.
Overlapped as shown in figure 4, two moushroom valve maximums are (complete), fluid is maximum by sectional area at this time, so the pressure produced
Drop is minimum.Sectional area cyclically-varying causes the mechanical periodicity of upstream pressure synchronization.
The mechanism of action
Power section makes the periodic pressure change of upstream pressure act on impact pipe nipple, and it is continuous just to form impact pipe nipple
Pressure inherence disc spring on formed vibration.By the change of the pressure cycle of the fluid that impacts pipe nipple, act in pipe nipple
It is small when big during the pressure of disc spring, so the balance pressure cap of impact pipe nipple is just under the double action of pressure and spring, it is past in axial direction
Multiple movement, so results in the reciprocating motion of other drilling tools for being connected with instrument in the axial direction.Since the compression of disc spring is
Consumed energy；So active force is downward when energy discharges, the direction of drill bit is just directed to.
Hydraulic blow system makes the drilling tool above and below oneself produce longitudinal reciprocating motion in wellbore, and such drilling tool is temporary in shaft bottom
When static friction become dynamic friction, in this way, frictional resistance just substantially reduces, so instrument can be reduced effectively because of well track
And the drilling tool produced draws phenomenon, ensure effective the pressure of the drill.
The frequency of hydraulic blow system vibration and the flow for passing through instrument are linear relationships, 8~28HZ of frequency range.Instrument
Moment impact 1/3 times of acceleration range acceleration of gravity.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
