FIELD: oil and gas industry.SUBSTANCE: method includes delivery of emulsified oil to an initial water separator, separation of water from emulsified oil and discharge of a part of water to waste water treatment facilities, further delivery of emulsified oil to buffer separating tanks, separation of gas and water in the buffer separating tanks, heating of emulsified oil, hot water separation and desalination of emulsified oil and pumping oil to consumers. After the initial water separator, before delivery to the buffer separating tanks, emulsified oil is delivered to a collector where partial gas separation takes place. At that hydraulic lock is made by means of the collector in the way of emulsified oil from the initial water separator to the buffer separating tanks. Pipelines for water and gas discharge from the buffer separating tanks ensure equal hydraulic friction. The buffer separating tanks are filled per 40-60% by volume and installed at the biggest height of the whole process chart. After the buffer separating tanks before heating emulsified oil is delivered to a vertical tank and its hold and separation takes place here. When pressure increases in the collector a part of emulsified oil is diverted from the collector to an additional tank. When pressure decreases in the collector emulsified oil in the additional tank is sent to the input of the initial water separator.EFFECT: provision of uniform delivery of the product from wells to the oil treatment plant and preventing failures in its operation.2 dwg |
