Definitions

  • the invention relates to a method for producing wells, in particular water-producing wells, and a well device for carrying out the method.
  • the filter tube sections consist of top tube, filter tube and sludge tube.
  • a so-called sole closure and jacket cementation is used to prevent the flowing together or the mixing of the liquids of the individual layers along the casing set or to prevent the muddy layers from slipping off.
  • a basic disadvantage of the conventional methods is that the diameters of the casing pipes are due to of the technology used gradually decrease from top to bottom, so that in the case of wells of medium and large depth, a borehole with a much larger diameter than the diameter of the lowest section must be made at the beginning. It follows from this that the amount of drilled soil to be removed is very large, the work steps of drilling and laying are extremely cumbersome, and systems of high efficiency and a corresponding energy supply are necessary for moving or actuating the large constructions.
  • the HU-PS 165 826 describes, for example, such a filter construction for wells, where protruding from the filter tube at certain intervals from the outside openings are provided to prevent constipation.
  • the filter tube designed in this way, the fine-grained sand of the liquid-storing layer can only be brought to the surface by compressors of large capacity and by high-pressure air.
  • a widening cavity can be formed in the area of the liquid-storing layer using a special drilling method and after the formation of a cavern or after the lowering of a filter tube set provided with a sludge tube, the cavern is filled with coarse-grained sand.
  • This embodiment has the disadvantage that the filter bed used in the area of the filter tube set has too high a resistance to the inflow of water and that this filter bed tends to silt up and therefore cannot be used in certain layer structures.
  • a common disadvantage of the two above-mentioned embodiments is that, even in the most favorable case, they can only put a single liquid-storing layer into production.
  • Another problem is the correct formation of a filter layer of appropriate permeability, for example a gravel filter around the filter tube section in the liquid-storing layer, which has also previously led to an increase in the diameter of the hole to be drilled, the productivity of the well not being able to be increased to a satisfactory extent .
  • a filter layer of appropriate permeability for example a gravel filter around the filter tube section in the liquid-storing layer
  • the aim of the invention is to eliminate the disadvantages listed and the economic and maximum exploitation of possibly several liquid-storing layers by a single well.

It is clearly evident from the figure that the casing set 1 arranged in the borehole has the same diameter throughout, and even in its filter pipe section 3 in the area of the liquid-storing layer 2.
