A mixture comprising an artificial resin as a binding material containing a catalyzer for controlling duration of binding and pumpability and an assorted granular material of high-strength forming the skeleton and salt filling and increasing pore spaces is homogenized and pumped into the corresponding producing section of the well into the area to be protected. After hardening of the mixture salt is dissolved from the obtained artificial stone and a filtering effect is achieved without binding the grains of the reservoir rock. Due to the mechanical characteristics and controlled porosity of the obtained artificial stone rock-parts, mainly sand delivered by the yielded fluidum into the well will be retained. An artificial stone with filtering effect can be prepared and hardened on the surface which can be inserted into the well and may be used as a sand-filter or with a desired shape and size it can be used for ecological purposes or in the industry to filter liquids or gaseous media, resp.
We claim: 1. A process for producing a high artificial stone with high permeability and filtering effect wherein from a homogenized mixture with a predetermined rheology comprising in a predetermined proportion an a furan resin with an added acidic catalyzer for controlling duration of pumping and binding and an assorted high strength granular material as well as salt soluble in water or thin acid dilution for forming pores is prepared, then obtaining said artificial stone by chemical reactive consolidation and subsequent dissolution of said salt by water or thin acidic dilution.
EXAMPLES 1) Composition of the mixture hardening at a temperature of 10� C. and under the pressure of 1 bar within 24 hours and which can be pumped for min. 3 hours:
