Title: Method and device for downhole treatment of well
Inventor: KUZNETSOV ALEKSANDR I
IPC: E21B43/25
Filed: 1996-04-12
Granted: 1997-01-27
Abstract: FIELD: oil industry. SUBSTANCE: treatment of well downhole zone infested with paraffined, asphaltic-resin or slime deposits is performed by filling a well with liquid of comparatively high density and creating water column pressure corresponding to stratum pressure. Then, depression chamber and pyrotechnic charge are brought into productive stratum. Used is slowly burning pyrotechnic charge with burning velocity of 1.5-2.5 mm/s ensuring emission of gases with high temperature. Burning is effected prior to creation of depression. On completion of burning, technological time-delay is exercised to allow gaseous burning products within productive stratum to be displaced with borehole liquid. After that, depression is created with displacement of borehole liquid from downhole zone and subsequent inflow of plug-liable components. Device for realization of aforesaid method has depression chamber with pyrotechnic charge and detonator connected with ground-surface control unit. Device is provided with burning housing connected through slotted metal sleeve with inlet valve unit of depression chamber. Unit is made up of case and valve proper with seal. Valve has inner space and holes in its walls. Space is capped atop with nut having side holes. Firing pin is seated in nut with its large diameter part. Located above firing pin is striker held from falling by a rod made of easy-fusible and burning material. Located on rod is heating coil connected with electric wires. Pyrotechnic charge with detonator is enclosed in burning housing. Inner space of inlet valve body communicates with depression chamber hollow. EFFECT: efficient cleaning of well downhole zone from slime generating components. 3 cl, 1 dwg

Abstract: FIELD: nonchemical water treatment processes. SUBSTANCE: starting solution is prepared by combining low-mineralized aqueous solution or drinking water with high-mineralized electrolyte solution. Then, starting solution is treated in anodic compartment of diaphragm electrochemical reactor. According to invention, high-mineralized electrolyte solution, prior to be combined with low-mineralized solution, is treated in cathodic compartment of the same reactor. Treatment is carried out in circulation mode inside circuit and pH of medium in the circuit is maintained between 12.5 and 13.5. Part of high-mineralized electrolyte withdrawn from circuit is used to be combined with low-mineralized solution in such proportions as to provide mineral concentration of starting solution within the range 0.3-5.0. Volume flow of starting solution through anodic compartment is 100 to 500 times that of high-mineralized electrolyte through cathodic compartment. Treatment is carried out until pH 7.2-8.2 and redox potential from +250 to +800 mV measured against silver chloride reference electrode are attained, while difference of pressures in anodic and cathodic compartments is maintained at a level ensuring filling of diaphragm pores by anolyte to the depth constituting 70 to 100% the thickness of diaphragm. Pressure difference is maintained either by maintaining reduced pressure in cathodic compartment and circuit or by maintaining overpressure in anodic compartment. Invention can be applied in all areas where disinfecting solutions are utilized. EFFECT: reduced corrosive activity of solution, reduced consumption of power and materials. 7 cl, 5 dwg, 1 tbl
