摘要： gas and oil producing industry, particularly, treatment of hydrocarbon gas with use of low-temperature process; applicable in field and plant treatment of hydrocarbon gases. SUBSTANCE: OPTIMET method of treatment of gas-condensate mixture includes supply of gas from well cluster for three-stage separation, compression and cooling of gas flow, introduction into gas flow of water-soluble volatile hydrating inhibitor, withdrawal from separator of fluid and its separation into hydrocarbon and aqueous phases, direction of water phase into flow of gas coming to one of separation stages, and supply of aqueous phase withdrawn from the third stage separator to heat exchanger of the first separation stage. Aqueous phase withdrawn from the second stage separator is mixed with aqueous phase withdrawn from the first stage of separation, and obtained mixture is supplied to mass-exchange part of desorber-separator installed on gas flow after its compression. Aqueous phase separating in desorber-separator is directed for utilization. Provided also is supply of aqueous phase from the first stage of separation to upper part of mass-transfer section of desorber-separator. Liquid aqueous phase from the second stage of separation is supplied to middle part of mass-transfer section of desorber-separator. EFFECT: reduced consumption of volatile hydrating inhibitor and improved ecological characteristics of plant operation in gas preparation at late stages of operation of gas-condensate deposits with dropping formation pressure. 3 cl, 1 dwg, 2 tbl

摘要： FIELD: gas-oil industry, possibly processes for treatment of hydrocarbon gas at process of producing it or in plants, namely cooling hydrocarbon gas after additional compressors before further drying and preparing it for transporting. SUBSTANCE: method comprises steps of cooling before drying crude gas in air cooling apparatuses with several rows of heat exchange tubes having inlet and outlet headers; feeding gas to inlet header and discharging it from outlet header in the same direction; supplying cooling agent such as atmospheric air to intertube space in direction opposite to gas feed direction in such a way that non-uniformity of distribution of gas flows in headers compensate non-uniformity of heat transfer along height of heat exchange tubes. EFFECT: optimal cooling mode of hydrocarbon gas without formation of crystal hydrates in apparatus for air cooling. 3 dwg, 1 tbl

摘要： oil and gas industry. SUBSTANCE: invention is related to methods of increase of productivity of wells by way of injection of liquid hydrocarbons into wells. Technical result of invention consists in enhanced efficiency of treatment of face zone of pool with large level of gas-bearing capacity under conditions of penetration of stratal water and water filtrate of technological fluids into sections of productive collector of low penetrability. Technology of treatment of face zone of pool includes pumping of hydrocarbons of gasoline fraction dispersed with gaseous agent. These hydrocarbons are pumped into pool with gas ratio 0.5-0.7 m/cu m and flow rate not less than 0.5- 0.8 l/s per running meter of opened interval with provision for forcing out of technological fluids from low-penetrability sections of face zone and water filtrate till phase penetrability by liquid and gaseous hydrocarbons is restored. EFFECT: enhanced efficiency of treatment of face zone of pool. 1 tbl

摘要： oil and gas producing industry, particularly, withdrawal of packer in major repairs of oil, gas and water wells. SUBSTANCE: included into withdrawing assembly are lower and upper centralizers, extensible mill cutter with cutters and bayonet lock for connection with packer. Components of withdrawing assembly are assembled, and assembly is lowered into well on pile string down to calculated depth. Dies of packer fixing mechanism are freed from clamping load on flow string in tension of pipe string and packer withdrawing from well. Point of cutting of bushing of packer fixing mechanism is defined more exactly and cutting is effected at 1-2 cm below dies of packer fixing mechanism. Pipe string is unloaded and bayonet lock is connected with a packer. Withdrawal of the packer from well is started from withdrawal of its upper part including dies and sealing member. Then, its lower end is withdrawn with the help of spear. EFFECT: higher efficiency of withdrawal of wedged packer by cutting of bushing of fixing mechanism for packer freeing from fixation. 2 dwg
