Method geostress survey technology is to be performed so far by Deep ground stress to measure maximally effective means, MTD
Can reach thousands of rice.It is many that the method is achieved with present daygeodynamics in stratum without the mechanics parameter knowing rock
Kind of parameter, and have easy and simple to handle, can carry out continuously or retest, measuring speed is fast, measured value is reliable
Advantage.
During hydraulic fracturing detecting earth stress, a most crucial link is the orientation of fracturing seam, i.e. exists
While using die device to obtain cause crack location and shape, the orientation of fracture is oriented, big to measure
The direction of secondary principal stress.
Conventional finder is a tubular article being connected to below packer, the i.e. shell of a fine copper,
A built-in pointer compass, photographic paper and the light source with intervalometer.Operation principle is: first in darkroom or
The photographic paper cut is put in people's finder by camera bag, to behind precalculated position under die device in hole, starts
Timer switch, 2.5v lamp bead continuous illumination 10s so that the photographic paper below pointer-type compass exposes in right amount；
After die terminates, darkroom or camera bag are taken out the photographic paper in finder, blow through photographic paper development is--fixing--
The step such as dry, thus obtain the relative direction of die device baseline and compass.
In use, can run into that battery electric quantity is not enough and under-exposure, photographic paper quality problems, unexpected leak
The factors such as light, printing paper are anti-loaded, developer solution quality, developing time control, have influence on orientation achievement.It is crucial that
Orientation printing paper installation, take out, develop and fixing whole during, be required to, at dark room operation, give
Detecting earth stress execute-in-place adds many difficulty, and efficiency is relatively low.And traditional photographic paper, development
Powder and fixing powder are bought and preservation difficulty is the biggest.

This utility model be the technical scheme is that a kind of hydraulic fracturing detecting earth stress die orientation
Device, it is characterised in that: having tube-like envelope, this tube-like envelope is by connecting pedestal and company respectively at its two ends
Joint forms closed cavity, is provided with movement mounting seat in closed cavity, and this movement mounting seat is connected with pedestal,
It is installed with video camera, compass in movement mounting seat and is furnished with the light tiles of battery；
Wherein compass base and surface all use transparent or semitransparent material to make, and compass base is marked with baseline,
Light tiles is installed on the close base end of compass, video camera be arranged at compass away from base end, video camera court
Arrange to compass.
Described tube-like envelope is connected with the capping of pedestal end count, is provided with sealing ring between tube-like envelope and pedestal；Institute
State tube-like envelope to be connected with the capping of union joint end count, between tube-like envelope and union joint, be provided with sealing ring.
Described compass uses the pointer compass of magnetic.
Described compass uses tuck formula compass.
Described compass uses steel-ball type compass.
The beneficial effects of the utility model are: this utility model finder have easy and simple to handle, image clear,
Performance is relatively stable, not by features such as field condition are limited, test quality and working efficiency are greatly improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment.
Fig. 2 is hydraulic fracturing detecting earth stress system schematic.
Detailed description of the invention
As it is shown in figure 1, the present embodiment is a kind of hydraulic fracturing detecting earth stress die finder, there is pipe
Shape shell 1, this tube-like envelope is connected to pedestal 5 and union joint 8 respectively by sealing lid 6, tube-like envelope 1 with
Sealing ring 7 it is equipped with between pedestal 5 and union joint 8.
In this example, tube-like envelope 1 coordinates pedestal 5 and union joint 8 to form sealing cavity, confined air in the enclosure
Intracavity is provided with movement mounting seat 9, and this movement mounting seat is connected with pedestal 5, fixed installation in movement mounting seat 9
There are video camera 2, compass 3 and are furnished with the light tiles 4 of battery.Its light tiles 4 is installed on the close base of compass 3
Seat 5 ends, video camera 2 be arranged at compass 3 away from pedestal 5 end, video camera 2 is arranged towards compass 3.
In this example, compass 3 has two kinds, and one is upright opening use, uses the pointer compass of magnetic, the end
Seat and surface are all transparent or semitransparent, and base is marked with baseline；Another kind horizontally or diagonally hole is used
Compass, uses tuck formula or steel-ball type, under gravity can be the most sagging or be in the bottom of compass,
Equally, base and surface are all transparent or semitransparent, and base is marked with baseline.
Fig. 2 is hydraulic fracturing detecting earth stress system schematic.Carrying out hydraulic fracturing detecting earth stress
Rock mass fracturing after, connection is had the die device of redirector appliance put in instrument connection by penstock
The test section position of fracturing, is pressurizeed to die device by water pump (oil pump) so that it is expand, be close to
Hole wall, along with pressure be gradually increased and high pressure crack re-open stress time so that fracturing crack is gradually increased,
The rubber moulding of die device embeds in crack, and release after continuing 30～120min is taken out after die device fully shrinks；
Record, the shape describing impression and position, and with the relative distance of finder baseline；Pass through finder again
The baseline fix recorded, calculates the orientation of impression；Thus calculate test section rock plane maximum master and answer
The direction of power.
The operation principle of finder in the present embodiment: when carrying out the die of hydraulic fracturing detecting earth stress section,
Compass 3 (using vertical compass, lateral aperture to use level compass during upright opening) is installed to finder
In movement mounting seat 9, and fix with pedestal 5；Afterwards the light tiles 4 installing battery is placed on compass 3
Lower section；Video camera 2 is arranged on the top of compass 3 again, opens video camera 2 activate switch, video camera 2
Start take pictures in real time and record, video camera 2 uses rechargeable type lithium battery power supply, be full of after can work continuously 3～
4 hours.
Movement is put into (including movement mounting seat 9, light tiles 4, compass 3 and video camera 2) pipe of finder
In shape shell 1, tightening sealing lid 6, single unit system can more than water pressure resistance 40MPa；Even by finder finally
It is connected on die device, lower hydrofracturing test section position in boring, pressurization, die.
After die terminates, take out die device and finder, measure and record the distance of crack impression and baseline, meter
Calculate the angle of impression and baseline；Take out the video camera 2 in finder, the photograph of the compass 3 captured by reading record
Sheet, measures the azimuth of baseline；Angle calcu-lation according to impression Yu baseline goes out the orientation of impression；Final basis
Hydraulic fracturing detecting earth stress principle, obtains the orientation of rock plane maximum principal stress.
