Description
Technical field
The present invention relates to downhole seismic observation technical field, more particularly to a kind of many tablelands shakes in underground based on regulation and control on well
Meter horizontalization device.
Background technology
Geoscience is the multidisciplinary synthesis science based on observation, and the signal to noise ratio for how improving observation is observation all the time
Most important problem in research.With economic activity and the quickening of urbanization process, the environment of surface seismic observation is increasingly disliked
It is bad；The foundation and man-made noise of the track traffics such as especially city, subway, railway, have had a strong impact on seismic monitoring instrument
Ambient noise.Effect of the borehole strain in ground observation is more and more important, for Research on Crustal motion provides High Accuracy Observation
Data.So, increasing seismic monitoring instrument and equipment is selectively mounted to underground.Recent domestic earthquake observating station
Start to develop from ground to Deep Underground, establish a large amount of deep-well observation stations and constitute deep-well sighting opportunity.
Japan started deep bore hole seismic observation before and after 1980, and by 2000, existing 22 deep-wells observation station, achieved
High accuracy, the seismological observation material of high s/n ratio that only ground sighting opportunity cannot be obtained, in terms of having promoted earthquake prediction
Research.Because borehole observation has far-reaching scientific meaning, since the nineties in 20th century, the state such as the U.S., Germany and Holland phase
After the underground long-term observation station is established, China just proceeds by the development of related downhole instrument from the later stage nineties, develops
Underground short period seismometer, achieves certain observation data and achievement in research.
It is installing instruments for many years experience have shown that, mounted in deep under ground sensor generally than be arranged on ground or near-earth
Table will stablize.Here it is why so much bomb shelter and discarded underground mine are often used as the seismographic station platform of low noise
Location.But, the place that build platform can not always find ready-made hole body or deep-well.And drill for this provide one it is practical
Solution, almost anywhere can by seismic sensor be mounted in deep under ground.
But in borehole observation, because wellhole is that have certain inclined, and seismic detector needs can in very flat position
Normal work, this is accomplished by a kind of device to adjust seismographic attitude, can be in horizontality normal work.
