Система подготовки содержит сепарационную установку первой ступени сепарации с газопроводом высокого давлени , соединенную нефтепроводом с деэмульсационной установкой, состо щей из последовательно соединенных нагревател , емкости с газовым барботером, электродегидратора (отстойника) и соединенной газопроводом низкого давлени с установкой подготовки газа. Барботер соединен с газопроводом высокого давлени установки первой ступени сепарации нефти или установки подготовки газа.This invention relates to processes for the preparation of oil and gas for transport in a field. The invention makes it possible to reduce the consumption of the demulsifier, improve the quality of the oil being produced and increase the capacity of the electric dehydrator included in the oil treatment system. The preparation system comprises a separation unit of the first separation stage with a high-pressure gas pipeline, connected by an oil pipeline with a demulsification unit, consisting of a series-connected heater, a tank with a gas bubbler, an electric dehydrator (settler) and a low-pressure gas line with a gas treatment unit. The bubbler is connected to a high pressure gas pipeline of a first stage oil separation unit or a gas treatment unit.

Изобретение относитс к подготовке нефти и газа к транспорту на промыслах.This invention relates to the preparation of oil and gas for transport in fields.
Цель изобретени - увеличение производительности установки и снижение расхода реагента.The purpose of the invention is to increase plant capacity and reduce reagent consumption.
П р и м е р. В водонефт ную эмульсию в количестве 530 м3/ч с содержанием воды 20% ввод т деэмульгатор из расчета 45 г на 1 т безводной нефти, затем ее разгазируют в сепараторе первой ступени при давлении 0,6 МПа и нагревают до 35°С. Смесь нагретой нефти с деэмульгатором поступает в горизонтальную емкость с газовым барбо- тером обьемом 100 м3 (0 3,0 м, I 14 м), разделенную на четыре массообменные камеры , не доход щими до верха аппарата на 200 - 300 мм вертикальными перегородками с переточными коробами. Барботеры установлены внизу каждой камеры в виде двух пакетов горизонтально расположенных труб диаметром 50 мм и длиной 1,5 м (16 шт)PRI me R. In the water-in-oil emulsion in the amount of 530 m3 / h with a water content of 20%, a demulsifier is added at the rate of 45 g per 1 ton of anhydrous oil, then it is degassed in a first stage separator at a pressure of 0.6 MPa and heated to 35 ° C. A mixture of heated oil with a demulsifier enters a horizontal tank with a gas bubbler with a volume of 100 m3 (0 3.0 m, I 14 m), divided into four mass transfer chambers that do not reach the top of the device 200 to 300 mm with vertical partitions with overflow boxes. Bubblers are installed at the bottom of each chamber in the form of two packages of horizontal pipes with a diameter of 50 mm and a length of 1.5 m (16 pcs)
с отверсти ми диаметром 2 мм и рассто нием между ними 85 мм. В барботеры подают 450 м3/ч из сепаратора первой ступени газ состава, мае.: № 0,4; С02 1,2; углеводороды Ci 74,0; С2 4,7; Сз 12,5; Со 2,3; Cs 1.2; Се и выше 1,4; или из системы подготовки газа. Давление в аппарате 0,4 МПа, давление в подвод щем газопроводе 0,4 сПа. Этот газопровод высокого давлени системы разделени нефти. Эмульси и газ в камерах движутс в противотоке. Из емкости газ направл ют потребителю, а разрушенна эмульси поступает в электродегидрататор- отстойник, где она раздел етс на обезвоженную нефть и воду. Вода направл етс на очистные сооружени , а нефть поступает в концевой сепаратор, где окончательно раз- газируетс при давлении 0,1 - 0,5 МПа. Газ поступает на установку подготовки газа, а обезвоженна и разгазированна нефть с содержанием воды 0,35%, хлористых солейwith holes with a diameter of 2 mm and a distance between them of 85 mm. 450 m3 / h are supplied to the bubblers from the separator of the first stage; gas of composition, May: No. 0.4; C02 1.2; hydrocarbons Ci 74.0; C2 4.7; Sz 12.5; From 2.3; Cs 1.2; Ce and above 1.4; or from a gas treatment system. The pressure in the apparatus is 0.4 MPa, the pressure in the feed gas pipeline is 0.4 cPa. This gas pipeline is a high pressure oil separation system. The emulsion and gas in the chambers move in countercurrent. From the tank, the gas is sent to the consumer, and the destroyed emulsion enters the dehydrator-settling tank, where it is separated into dehydrated oil and water. Water is directed to the sewage treatment plant, and oil enters the end separator, where it is finally expanded at a pressure of 0.1-0.5 MPa. The gas enters the gas treatment installation, and the oil with a water content of 0.35%, chloride salts is dehydrated and degassed.

27 мг/л, смол 8,0%, асфальтенов 1,7% и парафинов 2,9% откачиваетс в магистральный нефтепровод,27 mg / l, resin 8.0%, asphaltenes 1.7% and paraffins 2.9% are pumped to the main oil pipeline,
Система проверена в ПО Но брьскнефтегаз . При обезвоживании нефти по предлагаемой системе по сравнению с известной расход деэмульгатора снижен на 22 г/т, производительность отртойника увеличена на 30%, нефть получена нулевой группы качества вместо первой.The system has been tested in the software No brskneftegaz. With the dehydration of oil according to the proposed system, compared with the known consumption of the demulsifier, it is reduced by 22 g / t, the productivity of the grinder is increased by 30%, the oil is obtained of the zero quality group instead of the first one.
Таким образом, использование емкости с конструктивными характеристиками, приведенными выше, обеспечивает повышение производительности установки за счет увеличени производительности отстойника, снижение расхода деэмульгатора и улучшение качества нефти.Thus, the use of a tank with the design characteristics given above provides for an increase in the productivity of the installation by increasing the capacity of the settling tank, reducing the consumption of the demulsifier and improving the quality of the oil.
