the invention refers to a process and to a device for testing of aquifer, captured by a hydrogeological drilling,in order to determination hydrogeological characteristics and exploitation flow for each layer in the part or for a group of straturil which require a separate knowledge.the process according to the invention, it is characterized by that in the hole forata is input to a column constituted of filtered gutters, some sections with diameters increasing.from down to up, each section corresponding to an aquifer having many slits placed under a cushion of the layerfor the achievement of which separate cement plugs, within a space limited by a ring - side wall of the section and two layers respectively.the stoppers are achieved by placing, above and below the gaps in the section, respectively, of sealing assemblies, superior and inferior.the last of which it rests on a collar of a reductii, which joins the two successive sections, and the upper is due to launch an armed parts of weight of lining pipes,with such assemblies are introduced.still can be tested using any of the layers, for the lower and at the located closest to the surface only subansamblul seal lowerin which case, a lower pipe lining end is opened, and for...
