FIELD: oil and gas industry.SUBSTANCE: steel reservoir, which is open at the bottom, is used, with thickness of its walls equal to 7-10 mm, and having piping with escort vessels. At the same time outer pressure Pof hydrostatic water column is measured, as well as inner pressure Pof oil and gas medium inside the reservoir, and pressure difference ?P between them is calculated, which shall be excessive and shall not exceed 4000 Pa, from the following ratio: ?P=P-P?4000 Pa. At the same time flexible pipelines are used for piping, and controlled throughput capacity is calculated on the basis of the following ratio: F<(F+F+-F)<<F, where F- throughput section of the emergency gusher well; F, F, F- throughput section of flexible pipelines of gas, oil and operative control, accordingly; F- throughput section of the reservoir.EFFECT: possibility to use a light and simple to make structure, necessary to realise the method, possibility for efficient control of a reservoir when it is lowered or lifted.3 cl, 1 dwg |
