Technical field
The invention belongs to survey for the purpose of locating hydrogeological resources exploration engineering field more particularly to a kind of twin packer layering water plug and
Method.
Background technology
In survey for the purpose of locating hydrogeological resources and groundwater exploration, the detailed water of underground water is accurately obtained by being layered bailing test
Literary geologic parameter, obtain water-bearing layer the chemical fields in space, aerodynamic field, temperature field data, realize that layering to water-bearing layer is carved
It draws, for objectively recognizing hydrogeologic condition, accurate description water-bearing layer, reasonable generalization hydrogeological model establishes underground water
System mathematic model is relatively accurately evaluated groundwater resources and is of crucial importance.
Since technology and equipment limits, mostly based on single hole, layering drilling is less in domestic hydrogeological hole at present, passes
The layering pumping method of system has following two：
1) reducing is carried out in layering purpose section into during well, when being layered bailing test, pipe inner pallet sealing is carried out in reducer,
Then layering bailing test is implemented.The drawback is that：1. complicated into well construction since reducing is more, drilling operation cost is larger；②
Pallet water-stagnating effect is unstable, and the hydrogeological parameter reliability of acquirement is poor；3. the data cable of monitoring probe can not be worn in real time
Cross pallet sealing object, it is impossible to monitor the SEA LEVEL VARIATION for the target zone that draws water in real time；If 4. implement 3 layers with higher slice bailing test
When, it is excessively complicated into well construction.
2) when being layered bailing test in same footpath, carry out being layered sealing in pipe using pallet+hydro-expansive rubber+clay ball,
Then layering bailing test is implemented.The drawback is that：1. expanded rubber generally require 24-48 it is small when can be only achieved water-stagnating effect, it is auxiliary
Help the time long, efficiency is low；2. 2 layers or more of layering bailing test can not be implemented；3. carry out lower floor's bailing test, immersible pump exists
