摘要 |
FIELD: equipment for preparing oil for transportation. SUBSTANCE: method includes using flexible pipe of "Koltubing" device for wash- out of mud laydowns. This pipe is equipped with perforated portion, which is in waterproof connection with wash-out head, which is an operating end of flexible pipe. Operating end of flexible pipe is inserted in waterproof reservoir for preparing oil according to given trajectory. Pressure of wash-out fluid on operating end of pipe is set to 0.8-1.0 megapascals. It is displaced inside the reservoir at speed of no more than 1 meter per minute when traction force on operating end of pipe is 2-3 kg per cubic centimeter. During the process of wash-out cycle and laydowns removal, consumption of wash-out fluid being injected into reservoir is kept 8-10 cubic meters per 1 cubic meter of mud laydowns. EFFECT: creation of technology for wash-out and removal of mud laydowns from oil preparation reservoirs. 3 cl, 1 ex, 4 dwg |
