METHOD FOR INCREASING OUTPUT OF WATER WELL Russian patent published in 1999 - IPC

FIELD: mining industry. SUBSTANCE: method can be used in chemical industry and also in operation of thermal wells as well as in operation of wells producing potable mineral water. According to method, zone of well which is close to filter is subjected to different-polar pulses of current which are characterized by amplitude and relative duration. Pulses are sent through metal electrode. Destructed are walls of thin capillars in close to filter zone and extracted are water and sedimentations. In iodic-bromine well, this is achieved by setting amplitude of current pulses and their relative duration. Relative duration of current pulses is set as equal to 0.1-1.0 basing on prerequisite of ensuring thermodynamic equilibrium at boundary of metal electrode and close to filter zone. Constant density of current is maintained on aforesaid boundary in process of this operation. For this purpose, changed is relative duration of pulses during at least four hours until recording minimal value of relative pulse duration in period of 0.5-1 h. Application of aforesaid method ensures increased output of commercial highly mineralized water from thermal wells and from highly mineralized wells for iodic-bromine production processes. EFFECT: higher efficiency. 2 cl
