Effect improves detection work efficiency.
The present invention is achieved by the following technical programs.
A kind of hydraulic pressure that the present invention provides causes plug water pressure test in borehole method, comprises the steps:
1. pore-creating: complete the probing pore-creating in a hole；
2. install: successively by connecting with spring end between lower push rod and upper ejector pin, connect column sleeve
It is contained in outside spring, and seals at the end O RunddichtringO connecting post, lower push rod and upper ejector pin
In exposing the part suit watertight rubber ball connected outside post, the end cover dress top cap of upper ejector pin, pressure
Water test instrument pipeline connects aqueduct, thus lower push rod, upper ejector pin, spring, connection post, only
The mounted probe of the whole composition of water ball, top cap；
3. place: by mounted probe placement anticipated degree of depth in probing pore-creating, connect probe
Power control line, make the three-way electrovalve in probe be energized；
4. plug is caused: control three-way electrovalve for causing plug-like state；
5. water filling: open packer permeability test instrument and water pump, carries out high pressure water injection, reaches the pressure of regulation
After force value, keep high pressure water injection state, control three-way electrovalve simultaneously and switch to setting-out state；
6. packer permeability test: carry out packer permeability test, until having tested；
7. closing pressure release: close packer permeability test instrument and water pump, control three-way electrovalve switches to lets out
Pressure condition；
8. test is completed: repeat step 3. to 7., when repeating, make depth of probe relative to front every time
The deepest 4～10 meters, until completing the Sectional Test of whole probing pore-creating.
Described three-way electrovalve is threeway mutual-locking electric-controlled valve.
Described connection column sleeve is contained in outside spring, is specially connection post and lower push rod internal and external threads connects
Connect, upper ejector pin and connection post internal and external threads connect.
The beneficial effects of the present invention is: 1. improving detection work efficiency, the present invention is to complete
Disposably being carried out continuously the test in a hole after the probing in one hole, each hole section testing time is little
In 1 hour；2. improving exploration precision, cause plug pressure foot, pressurize is effective, and measuring accuracy is relatively
Rig packer permeability test is high 2 times；3. hole clipping accident rate is low, whole probe only with a set of water pipe,
Not having oil pipe, probe appurtenance is few, it is simple to execute-in-place, reduces hole clipping accident.
