MOBILE UNIT FOR PREPARATION AND DELIVERY OF GAS-AND-LIQUID MIXTURE OR GAS TO WELL

摘要

FIELD: oil-and-gas producing industry; equipment for oil and gas wells. ^ SUBSTANCE: proposed unit is used for performing jobs inside pipes with the use of gas of safety composition generated by unit or associated gas from external source, as well as for reduction of bottom-hole pressure for intensification of fluid flow. Used as inert gas sources are exhaust gases from two internal combustion engines: chassis engine and compressor engine which are cleaned and mixed in gas booster pump at required ratio and are delivered to well. Safe composition of mixture is obtained by regulating amount of oxygen in exhaust by means of membrane washers fitted in exhaust branch pipes of each engine; accuracy of proportioning of each component is ensured by availability of individual hydraulic drive in each pump. ^ EFFECT: extended functional capabilities; enhanced ecological safety. ^ 5 cl, 2 dwg
