Abstract

1. Сепарационная установка, содержащая колонну с трубопроводами подвода газожидкостной смеси и отвода нефти, воды и газа, при этом колонна выполнена составной из соединенных между собой двух и более секций, каждая из которых содержит прямолинейный участок трубы, трубопроводы подвода газожидкостной смеси и отвода нефти и воды соединены с секциями патрубками подвода газожидкостной смеси и отвода нефти и воды, а выводы патрубков отвода нефти и воды соединены соответственно с нефтеотстойными и водоотстойными участками секций, нижний конец каждой секции заглушен, при этом диаметры секций выполнены равными или неравными, углы наклона секций выполнены равными или неравными, отличающаяся тем, что секции выполнены в виде шурфов, оси секций расположены перпендикулярно или наклонно к горизонтальной поверхности, длины секций равные или неравные, гидравлические сопротивления патрубков подвода газожидкостной смеси равные или неравные, патрубки отвода воды расположены внутри секций, патрубки отвода нефти подсоединены к боковым стенкам секций, патрубки отвода воды выполнены с возможностью изменения длины, расстояние между осями секций равное или неравное, оси секций расположены в одной или разных вертикальных плоскостях, стенки секций контактируют или не контактируют между собой, верхний конец каждой секции заглушен.2. Сепарационная установка по п.1, отличающаяся тем, что на выходе трубопровода подвода газожидкостной смеси расположено устройство для деления газожидкостного потока, причем число выходов из устройства для деления газожидкостного потока не меньше числа секций.1. A separation unit containing a column with pipelines for supplying a gas-liquid mixture and for discharging oil, water and gas, wherein the column is made up of two or more sections interconnected, each of which contains a straight pipe section, pipelines for supplying a gas-liquid mixture and oil water is connected to sections by branch pipes for supplying a gas-liquid mixture and drainage of oil and water, and the conclusions of branch pipes of drainage of oil and water are connected respectively to the oil-sludge and water-sump sections of the sections, the lower end Each section is muffled, while the diameters of the sections are equal or unequal, the angles of inclination of the sections are equal or unequal, characterized in that the sections are made in the form of pits, the axes of the sections are perpendicular or inclined to a horizontal surface, the lengths of the sections are equal or unequal, the hydraulic resistance of the pipes gas-liquid mixture supply equal or unequal, water drain pipes are located inside the sections, oil drain pipes are connected to the side walls of the sections, water drain pipes are made with ozhnostyu change in length, the distance between the axes of sections equal or unequal, the axis sections located in the same or different vertical planes, the wall sections are in contact or not in contact with each other, the upper end of each zaglushen.2 section. The separation unit according to claim 1, characterized in that at the outlet of the gas-liquid mixture supply pipeline there is a device for dividing the gas-liquid stream, and the number of exits from the device for dividing the gas-liquid stream is not less than the number of sections.
