Abstract: FIELD: drilling of wells, separation and fixing of collectors and gas wells in process of their termination. SUBSTANCE: invention ensures increased quality of separation and fixing of wells in process of termination of construction of wells with simultaneous provision for hydraulic cleanness of productive part in the course of their exploitation with planned discharge with minimal water content. According to process shaft of well up to roof of productive level is fixed by operational casing string. Shaft opposite to productive level is widened, gear overlapping pool in the form of impermeable shell is sunk down to face together with operational casing string. Well-collector is open and inflow of fluid into well is initiated. Main shaft is packed above roof of productive level prior to pressure grouting of casing string. Ring space between tubing strings used to lower additional intertube packer and wall of gear overlapping pool is packed after pressure grouting. Later face zone of productive pool is treated. After it permeable grouting composition is forced into widened zone of productive pool. Simultaneously working fluid and products of reaction after acidic treatment are forced out of there. Gear for implementation of process of termination of construction of well in agreement with proposed invention includes body, packing unit with insulating members and drive coming in the form of cylinder and ring piston-pusher, additional packer connected to tubing string, tail part, gear overlapping pool, shoe with valve. Lower part of additional packer has partition with conduits and central hole housing stroke limiter installed in it for axial movement. Radial conduits are made in walls of packer. Tail part has partition that limits stroke of limiter. Upper part of gear overlapping pool houses coupling with non-return valve.

Abstract: FIELD: detergents. SUBSTANCE: invention, in particular, relates to removing pollutions of organic and inorganic nature from oil-containing equipment of any shape and volume: railway and car cisterns, sea tankers, overground and underground tanks (filling stations), surfaces of metal structures, etc. , and also from polluted areas, including ground surfaces. Method involves get treatment of surface with detergent, in particular 2- 10% aqueous solution of composition, which forms film on cleaned surface to prevent vaporization of residual pollutions and to allow performance of fire-repairing and other types of explosive operations after cleaning of surfaces with no need of degassing and use of degassing and ventilation equipment. Jet treatment is accomplished in two steps with washing machines at pressure 4 to 40 atm and temperature of solution between 20 and 90 C. Volume of solution supplied to surface and volume of solution entraining washed off pollutions are controlled in such a manner as to limit accumulation of spent mix in cleaned reservoir in the first step to 1/3 its volume and to completely exclude accumulation of spent mix in the second step. Alternatively, jet treatment can be effected with washing machines at pressure 4 to 40 atm and temperature of solution between 20 and 90 C. In the two methods, collecting tank receives spent mix, which is continuously separated to remove pollutions from the surface of solution, pollutions being directed to consumer and solution returned on the surface to be cleaned. Detergent composition contains, wt %: C11-C13 alkylbenzenesulfonate 4.5-7.5, Neonol 2.0-7.0, polyethylene glycol 3.0- 11.0, and sodium carbonate and/or bicarbonate - the balance. EFFECT: increased degree of cleaning at minimal consumption of detergent. 5 cl
