Title: Fire-fighting method in ground tanks
Inventor: IVANSHCHIKOV YURIJ VASILEVICH

Abstract: FIELD: fire extinguishing. 
     SUBSTANCE: invention relates to fire extinguishing in ground tanks filled with various combustible liquids, for example, oil, diesel fuel, kerosene, gasoline etc. Essence of the invention consists in the following. Under ground reservoir, below underground level, underground reservoir of larger volume than volume of ground reservoir filled with fire-extinguishing substance is coaxially installed. Ground reservoir is connected to underground reservoir via drain branch pipe with automatic valve. System also includes a pump for supply of fire-extinguishing substance through the delivery pipeline with two valves – upper and lower, supplying fire-extinguishing substance from the underground reservoir to the top of the ground reservoir. In initial (normal) state (when there is no fire) automatic valve of drain branch pipe is in closed position, isolating volumes of ground and underground reservoirs. Pump is switched off, the upper valve of the pressure pipeline is open, and the lower one, which serves for fire-extinguishing substance withdrawal, is closed. In case of fire (fire) or excessive increase of temperature in the ground reservoir, the drain branch pipe valve automatically opens and connects the aboveground and underground reservoirs volumes and the liquid from the ground reservoir starts flowing through the drain branch pipe into the underground reservoir. At the same time pump is automatically connected, it starts to select fire extinguishing substance from underground reservoir and supplies it from above to ground reservoir. Volume of the fire extinguishing substance taken by the pump from the underground reservoir is greater than the volume of flowing liquid from the ground reservoir per unit of time, which creates vacuum in the underground reservoir, thereby increasing the rate of flow of liquid from the ground reservoir into the underground reservoir. When extinguishing fire in objects located near ground reservoir, top pressure valve is closed, automatic drain discharge pipe valve is also closed. Pump is switched and fire extinguishing agent by means of a fire hose mounted on the lower valve, directed to the fire center and fire is extinguished. Crane and pump control is automated and synchronized. 
     EFFECT: technical effect consists in improvement of efficiency of fire extinguishing in ground reservoirs, as well as efficiency of fire extinguishing of objects located near ground reservoir, in expansion of fire suppression method functional capabilities and in reduction of costs for production and replacement of underground reservoir located under ground reservoir.

Abstract: FIELD: oil, gas and coke-chemical industries. 
     SUBSTANCE: invention relates to oil and gas industry, particularly, to implementation of interval multi-stage hydraulic fracturing in wells with horizontal termination. Method of multistage hydraulic fracturing in well with horizontal termination includes lowering of hydraulic fracturing assembly with adapter on tubing string to finished and cased well with horizontal section. Structure of assembly comprises packer of hydraulic action, upper and lower anchor, there are two folding check valves inside the assembly. Adapter stem passes through the packer and has a seat at the end. After the assembly is lowered to the preset interval, the ball is dropped and pumped to the seat seat attached to the adapter stem part by shear pins. Further, excessive pressure is created in the tubing string, due to which the pins are cut off in the packer of hydraulic action; anchors are moved, which in turn deforms the packer collar. Cuff deformation promotes tight disconnection of intervals before and after assembly. After that pressure is released in the tubing string and stretching is no more than 2 tf. Pins are cut in the seat of the adapter stem section. Packer is unloaded to packer of not less than 5 tons and stem part of adapter moves downwards. Ball and landing seat fall out of barrel part of adapter. Further, fluid-fracturing is pumped into the tubing string, the liquid fills part of the casing string below the packer and process cracks are formed in the productive formation owing to excessive pressure. Further, the tubing string is lifted, the stem part of the adapter comes out of the packer, which helps to close the flap check valves. Thus, interval hydraulic fracturing of formation is performed with subsequent shutdown of interval and pressure retention under packer. Further, work on hydraulic fracturing of the formation in the required amount is performed with leaving the packers in the well shaft. After performing the required number of intervals of hydraulic fracturing in horizontal section on flexible tube, cutters are lowered, drilling of remaining after fracturing is performed with washing of metal and rubber chips on surface. At the end of operations, the well is developed, downhole equipment is lowered and brought to the mode. 
     EFFECT: technical result consists in development of hydraulic fracturing, which enables to conduct interval hydraulic fracturing using a system of folding check valves.
