METHOD TO PRODUCE INORGANIC BORING REAGENT AND INSTALLATION FOR ITS IMPLEMENTATION Russian patent published in 2004 - IPC

FIELD: petroleum industry. SUBSTANCE: the invention relates to the petroleum industry and is dealt with a method to produce the anorganic boring reagent out of natural mineral water and the installation for its implementation. The method provides for submission of the mineral water from a producing well into a crystallizer, refrigerating of the mineral water down to temperature +10 - (-20) C, crystallization of inorganic salts, settling, pouring out of a mother liquor into the settler, the mother liquor pumping out from the settler into the injection well. Free from the mother liquor anorganic boring reagent is in succession moved from the crystallizer to the filtering site and to the assembly of the end product filling. The Installation for implementation of the method in addition to a casing string, an underground pipe and a centrifugal pump contains a crystallizer supplied with a liquid dispersing agent and drain branch-pipes with latches, a settler linked with the centrifugal pump and the injection well, a filtering site with a mesh base and a tray linked with a settler, and an assembly of the end product filling. EFFECT: production from the natural mineral waters of the anorganic crystallized boring reagent with 70 % specific humidity. 2 cl, 1 tbl, 2 dwg
