It is arranged on as a example by the lower section for scraping wall device what is illustrated.
In the present embodiment, alternatively, well logging apparatus are storage type logging instrument.
Specifically, storage type logging instrument does not need connection cable, can easily G.I.H, with brill
Tool 10 is rotated, and the connection without considering cable is designed, and storage type logging instrument is as integrated pipe column is from going into the well
During rising, measuring state is constantly in, can arbitrarily obtain required measurement data.
Alternatively, scrape wall and be set to scraping wall.
Further, on the basis of the technical scheme of above-described embodiment, Fig. 6 is carried for the embodiment of the present invention
The structural representation for scraping wall device for supplying, as shown in fig. 6, in the present embodiment, scraping wall device includes：
Body 21 and scrape cutter hub 22 with inside body 21.
In the present embodiment, cutter hub 22 is scraped to be locked on body 21 by pin 25.When scraping wall device also
Do not proceed by when scraping wall operation, scrape cutter hub 22 positioned at the inside of body.
Due in plug operation process is bored, scraping wall device 20 as drilling rod 11 is rotated, therefore scrape wall device
20 are preferably selected to be scraped cutter hub 22 and be received in and scrape in wall device 20, controllable when needing to carry out scraping wall
System is scraped cutter hub 22 and is ejected, and the inwall with well inner sleeve is contacted, and carries out scraping wall operation.
In the present embodiment, scraping wall device 20 also includes：It is arranged on body 21 and scrapes between cutter hub 22
Spring 23 and pressure-bearing plug 24.
Specifically, spring 23 and pressure-bearing plug 24 are used to provide the shearing force of shear pin.
When do not proceed by scrape wall when, spring 23 be in compressive state.
Further, on the basis of the technical scheme of above-described embodiment, Fig. 7 is carried for the embodiment of the present invention
The structural representation of the tubing string embodiment five of confession, as shown in fig. 7, in the present embodiment, the tubing string is also wrapped
Include：It is arranged on scraping between wall device 20 and drill bit 12, and for controlling described to scrape cutter hub from described
The sliding sleeve switch 40 of body ejection.
Wherein, if well logging apparatus 30 are arranged on the top for scraping wall device 20, sliding sleeve switch 40 is arranged on
Scrape between wall device 20 and drill bit 12, if well logging apparatus 30 are arranged on the lower section for scraping wall device 20,
Sliding sleeve switch 40 is arranged on to be scraped between wall device 20 and well logging apparatus 30.That is, sliding sleeve switch
40 will be close to setting with wall device 20 is scraped.
Specifically, when scrape wall operation, by steel ball is put into drilling rod, treating that steel ball drop is arrived
Sliding sleeve switch 40, makes the axial seal of sliding sleeve switch 40, and to being suppressed in sliding sleeve switch 40 to a spy
Fixed pressure value, power and the shearing force for being more than shear pin with joint efforts of spring 23 that pressure-bearing plug 24 bears,
After shear pin stress is interrupted, the inner spring 23 of body 21 will scrape cutter hub 22 and eject, and now scrape cutter hub
22 are close on the inwall of well inner sleeve, just can carry out scraping wall operation by above putting charging integrated tubing string.
Fig. 8 is the structural representation of sliding sleeve switch provided in an embodiment of the present invention, as shown in figure 8, sliding sleeve
Switch 40 includes：Outer tube body 41, the sliding sleeve 42 being arranged in outer tube body 41, it is arranged on sliding sleeve 42
The axially extending bore 44 connected with pitching mouth 43 of pitching mouth 43 and the radial direction being connected with axially extending bore 44
Through hole 45.
Wherein, one end of outer tube body 41 is connected with wall device is scraped, the other end and drill bit of outer tube body 41
It is connected.
Specifically, it is necessary to when scrape wall operation after completing to bore plug operation, to putting into steel in drilling rod 11
Ball is blocked the axially extending bore 44 of sliding sleeve 42, by drilling rod 11 to the pitching mouth 43 of sliding sleeve 42
Suppress to a specific pressure value, scraping wall scrapes cutter hub ejection, and now sliding sleeve 42 is in outer tube body
Position in 41 is first position, when continuing to be pressurized to a preset value, between sliding sleeve 42 and outer tube body 41
The pin of connection is cut off, and sliding sleeve 42 slides to the second place in outer tube body 41, and now sliding sleeve 42 is stuck in
On the inwall of outer tube body 41, the radial direction through hole 45 of sliding sleeve 42 corresponds to the inwall of outer tube body 41 and sliding sleeve 42
Between the annular space 46 that is formed, this annular space 46 connects with one end of outer tube body 41, and mud can
In entering to annular space 46 from one end of outer tube body 41, then the radial direction through hole 45 of sliding sleeve 42 is flowed into,
Then flow to the other end 3 of outer tube body 41 from the axially extending bore 44 of sliding sleeve 42, outer tube body 41 it is another
End connects with drill bit 12, and mud can flow out from bit port.Because mud can be in sliding sleeve switch
Circulated between 40 and drill bit 12, therefore in clean-out service, mud can be recycled to the hydrophthalmia position of drill bit
Put, the impurity recycling in the space between drill bit 12 and sliding sleeve switch 40 can be gone out.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than right
Its limitation；Although being described in detail to the present invention with reference to foregoing embodiments, this area it is common
Technical staff should be understood：It can still modify to the technical scheme described in foregoing embodiments,
Or equivalent is carried out to which part or all technical characteristic；And these modifications or replacement, and
The scope of the essence disengaging various embodiments of the present invention technical scheme of appropriate technical solution is not made.
