Method and apparatus for water flow stimulation in a well |
摘要 |
The invention is directed to the stimulation of water flow into a substantially dry well shaft from adjacent rock and soil strata bearing water supplies by developing passages from such water supplies through the well walls. Liquid or gaseous nitrogen and liquid or gaseous carbon dioxide are introduced into the well either individually or in combination and alternately pressurized and depressurized to cause the rock structure between said well wall and said water supplies to be exposed to high pressures and fractured to thereby open a passage from said water supplies to said well. A well cap is provided to seal the well and retain the pressure developed therein while providing for the introduction of the required materials. Means are also provided to release the pressure in the well quickly to return same to its unpressurized condition.
