Description
Technical field
The present invention relates to a kind of installation borehole survey technology of seismic precursor borehole apparatus more particularly to a kind of borehole surveys
Device.
Background technology
Seismic precursor borehole apparatus is typically mounted at diameter 130mm~150mm, in the drilling that 60~200 meters of depth.Due to
Drilling is deeper, and diameter is small, if drill hole inner wall is rough, has probe stone etc. to appear on the inner wall of drilling, can make boring instrument
Device cannot be installed smoothly, and instrument cannot be attached to position, and serious it will cause borehole apparatus to be stuck among drilling, can neither fall on
Shaft bottom carries to come up yet, and such borehole apparatus probe will just be scrapped.If borehole apparatus to smoothly install, must just there is one
The device measured to bore diameter is covered, determines that the minimum diameter of drilling is more than instrument diameters, ensures that instrument installation is smooth.
In the prior art, initial well logging apparatus is to fix a tiny plummet of diameter with lining rope, and personnel are with warp for well logging
Test and slowly put lining rope toward underground, if feeling that plummet blocks a little, can in the shaking lining rope up and down of this position gently, with
What confirmation plummet was encountered is the probe stone on the borehole wall or the borehole wall.
Generally there is water in drilling, if water can use downhole imaging instrument to log well, underground is taken the photograph very totally without floating material
As the situation in well can be completely presented on installation personnel at the moment by instrument, installation personnel is allowed to judge whether drilling fits according to image
Close instrument installation.
All there is prodigious defect in above-mentioned existing logging mode, can not completely be measured drilling quality：
Lining rope plummet well logging mode, larger probe stone can be measured, and it is smaller will not then be found, but also
Depend particularly on the experience of well logging personnel；
The logging mode of downhole imaging instrument is more intuitive and easy to understand, but requires the water in drilling totally and without floating material, and
General well water has floating material, seriously affects the well logging of downhole imaging instrument, if it is the well newly bored, then water can muddiness can't bear, take the photograph
As instrument is even more all not see a bit.

At diameter of a circle be drilling minimum diameter size.
The borehole survey device of the present invention, there are four wedge blocks of logging well for the installation of well logging cylinder surrounding, during being put toward underground,
Well logging wedge block can find the minimum diameter of drilling and preserve, when well logging apparatus is up carried out of well, wedge shape
Block will receive in well logging cylinder, and well logging apparatus is made smoothly to propose to drill.After well logging apparatus proposes drilling, drilling that wedge block is measured
Minimum diameter position is restored, and measurement must can drill minimum diameter, to confirm whether borehole apparatus can be installed, for borehole apparatus
Installation escorts.
Specific embodiment：
As shown in Figure 1 and Figure 2, bale handle 1 and well logging cylinder 2 weld together, and log well 2 diameter 80cm of cylinder, straight much smaller than drilling
Diameter；There are four wedge block 3, wedge block 3 makes wedge block 3 together with being sold with thimble 4 by voussoir pin 7 for 2 surrounding of cylinder of logging well distribution
Pin 7 can be surrounded to rotate, thimble 4 is withstood under the active force of thimble spring 5 on the spine slot of wedge block 3, makes wedge block 3 can only
To well logging 2 center rotating of cylinder, negative direction is then not all right；Thimble 4 is merely able to slide laterally along sliding slot 9 with wedge block；Slotted-guide pin
Son 8 and weight bar 10 weld together, and weight bar 10 and pouring weight 11 weld together.
Borehole survey device pulls outward thimble 4 and wedge block 3 along sliding slot 9 before going into the well, and squeezes crossed strip, draws
After in place, pouring weight 11 drives weight bar 10 and sliding slot pin 8 to walk downward, and sliding slot pin 8 enters sliding slot pinhole, makes 4 He of thimble
Wedge block 3 cannot slide laterally.Wedge block 3 will be opened to maximum again, i.e. thimble 4 withstands on wedge shape under the action of thimble spring 5
The round diameter of the most inner side (location A) of 3 spine slot of block, such four wedge blocks 3 composition will be greater than bore diameter (Fig. 1).
Lining rope ties up on bale handle 1, well logging cylinder 2 slowly past decentralization under the gravity of pouring weight 11, if borehole wall diameter becomes
Small, the borehole wall can then impact four wedge blocks 3 of well logging 2 surrounding of cylinder, so that wedge block 3 is rotated along wedge-shaped pin 7 and shrink, thimble 4 exists
From A points to B points or C points under the action of thimble spring.
After falling on shaft bottom under well logging cylinder, pouring weight 11 contacts shaft bottom, makes weight bar 10 with sliding slot pin 8 relative to measuring cylinder
2 walk upwards, and sliding slot pin 8 is proposed from pinhole, and thimble 4 and wedge block 3 are past along sliding slot 9 under the active force of crossed strip 6
Center is slided, to which wedge block 3 is retracted to 2 inside (Fig. 2) of measuring cylinder, in this way, smoothly can propose to drill by measuring cylinder.
After measuring cylinder proposes drilling, thimble 4 is slid in and out with wedge block 3 along sliding slot 9, behind in-position, will be slided
Slot pin 8 is inserted in pinhole, and thimble 4 is constant relative to the position of wedge block 3, measures the straight of the circle of four wedge blocks 3 composition
Diameter size, this diameter are exactly the minimum diameter to drill.
The present invention has considerable advantageous effect compared with prior art, and the installation of seismic precursor borehole apparatus can be made suitable
Profit reduces installation accident.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Any one skilled in the art is in the technical scope of present disclosure, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of claims
Subject to enclosing.
