Description
Technical field
The utility model relates to a kind of installation borehole survey technology of seismic precursor borehole apparatus more particularly to a kind of drillings
Measuring device.
Background technique
Seismic precursor borehole apparatus is typically mounted at diameter 130mm~150mm, in the drilling that 60~200 meters of depth.Due to
It drills deeper, and diameter is small, if drill hole inner wall is rough, there is probe stone etc. to appear on the inner wall of drilling, boring instrument can be made
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 mentions 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 greater than instrument diameters, guarantees that instrument installation is smooth.
In the prior art, initial well logging apparatus is to fix the tiny plummet of diameter with lining rope, and the personnel that log well are with warp
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 be logged well, underground is taken the photograph very completely without floating material with downhole imaging instrument
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.
Above-mentioned existing logging mode all haves the defects that very big, can not completely be measured drilling quality:
Lining rope plummet well logging mode, biggish 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 completely and without floating material, and
General well water can all have floating material, seriously affect the well logging of downhole imaging instrument, and if it is the well newly bored, then water meeting muddiness can't bear,
Video camera is even more all not see a bit.

After the borehole survey device proposes well, the thimble, voussoir pin and wedge block are placed on the outside of the sliding slot, institute
State the lower end that sliding slot pin fixes the thimble and wedge block into the sliding slot pinhole, group on the outside of the upper end of the wedge block
At diameter of a circle be drilling minimum diameter size.
The borehole survey device of the utility model, there are four the mistakes that wedge block of logging well, past underground are put for the installation of well logging cylinder surrounding
Cheng Zhong, well logging wedge block can find the minimum diameter of drilling and preserve, when well logging apparatus is up mentioned out of well,
Wedge block will receive in well logging cylinder, and well logging apparatus is made smoothly to propose to drill.After well logging apparatus proposes drilling, wedge block is measured
The minimum diameter position that drills is restored, and measurement must can drill minimum diameter, to confirm whether borehole apparatus can be installed, to drill
Instrument 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 blocks 3 together with the pin of thimble 4, to make wedge block 3 by voussoir pin 7 for 2 surrounding of cylinder of logging well distribution
It can be rotated around pin 7, 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, opposite 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 before going into the well, by thimble 4 and wedge block 3 along sliding slot 9, 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, the slowly past decentralization under the gravity of pouring weight 11 of cylinder 2 of logging well, if borehole wall diameter becomes
Small, the borehole wall can then impact four wedge blocks 3 of well logging 2 surrounding of cylinder, rotate wedge block 3 along wedge-shaped pin 7 and shrink, thimble 4 exists
From A point to B point or C point 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 9 past along the chute under the active force of crossed strip 6
Center sliding, so that 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 utility model has considerable beneficial effect compared with prior art, and seismic precursor borehole apparatus can be made to pacify
Dress smoothly, reduces installation accident.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
