SOLUTION FOR REGENERATION OF FILTERS OF HYDRO-GEOLOGICAL WELLS

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to the field of prospecting drilling and can be used for recovery of flow rate of hydro-geological wells, which have reduced it due to deposition on the surface of the filter contained in water CaSO₃, MgCO₃, CaSO₄ salts. Solution for regeneration of filters of hydro-geological wells includes the following components, wt%: trichloroacetic acid 10–17, sulfamic acid 8–11, corrosion inhibitor CPI-19 0.3–0.5, surfactant OP10 0.5–1.0, sodium tripolyphosphate 8–12, adipic acid 8–12, water – balance.;EFFECT: invention increases efficiency of filter cleaning from salts deposited on its surface by 40 %.;1 cl, 1 tbl
