Abstract
The invention relates to the field of the provision of the necessary technical facilities for oil production, and more specifically, to the provision of flow measurements of the quantity and quality coefficients of a wellbore fluid, particularly for breaking down foam. In the method for breaking down foam during gravity separation of a gas-liquid mixture, the resulting foam in a mixture-receiving area is entrained by a liquid flow which flows down along a partition to an annular wall-adjacent gap, where this flow encounters a flow of degassed liquid, forcibly fed from a liquid outlet of a separator, whereupon the majority of the foam is broken down, and the flow is then directed into a settling area of a tank. The gas separated from the foam rises into the upper portion of the mixture-receiving area. The device comprises a tank for gravity separation of a gas-liquid mixture, wherein the tank contains a partition between the mixture-receiving area and the settling area with an annular gap along the wall of the tank; a gas-liquid mixture inlet branch pipe with a lower outlet opening is installed at a specific height from the partition; on the housing of the separation tank in the mixture-receiving area, connecting pipes for the intake of a degassed liquid are mounted tangentially to the wall, said degassed liquid being pumped over by a pump from the liquid outlet of the separator into the mixture-receiving area of the tank, through a pipeline of a return circuit. Channels for discharging the free gas are provided in the partition. The invention makes it possible to promote the breakdown of the resulting foam in the mixture-receiving area of the tank, increase the effectiveness of the process of separating the gas-liquid mixture, and improve the operating conditions of the monitoring and measuring equipment.

Уровень техники The invention relates to the field of technical arrangement of oil production, and more particularly to providing in-line measurements of the quantity and quality indicators of well fluid, in particular for the destruction of foam. State of the art
Известен способ гидромеханической деструкции пены по изобретению согласно авторскому свидетельству СССР ([1], SU 1282865, МПК B01 D19/02, опубл. 15.01.1987), по которому пена, перемещающаяся по коридору между двумя ограничительными стенками, разрушается с помощью водяной завесы, подаваемой поперек потока пены. Применительно к теме настоящего изобретения это решение можно рассматривать в качестве аналога, содержащего элементарное решение, которое может быть использовано и в данном случае. A known method of hydromechanical destruction of the foam according to the invention according to the copyright certificate of the USSR ([1], SU 1282865, IPC B01 D19 / 02, publ. 15.01.1987), in which the foam moving along the corridor between the two boundary walls, is destroyed using a water curtain, fed across the flow of foam. In relation to the topic of the present invention, this solution can be considered as an analogue containing an elementary solution, which can be used in this case.
Наиболее близким аналогом заявленного изобретения выбран патент Российской Федерации на полезную модель ([2], RU90350, МПК B01D45/12, опубл. 10.01.2010), в котором использовано весьма близкое конструктивно-компоновочное решение сепаратора и организация потоков рабочих сред, включающее патрубок для подвода газожидкостной смеси, закрепленный в верхней части цилиндрического корпуса, на верхнем торце корпуса установлен патрубок отвода газа, а в нижней части - патрубок отвода дегазированной жидкости из сепаратора. В верхней части цилиндрического корпуса вблизи патрубка подвода газожидкостной смеси установлено сопло, направленное тангенциально к стенке цилиндра, создающее вращающийся по стенке цилиндра поток дегазированной жидкости, отбираемой через патрубок из жидкостной полости на выходе цилиндра. Однако в данной конструкции сепаратора не решена проблема пеногашения, газовые пузырьки, составляющие пену, будут увлекаться как в трубопровод отвода жидкости (внося существенную долю свободного газа в жидкостный поток), так и в поток отвода газа (привнося в отбираемый газ заметную жидкостную компоненту). The closest analogue of the claimed invention is the patent of the Russian Federation for a utility model ([2], RU90350, IPC B01D45 / 12, published January 10, 2010), which uses a very close structural and layout solution of the separator and organization of working medium flows, including a pipe for the gas-liquid mixture inlet, mounted in the upper part of the cylindrical body, a gas outlet pipe is installed on the upper end of the body, and a pipe for removing degassed liquid from the separator is installed in the lower part. In the upper part of the cylindrical body near the nozzle for supplying a gas-liquid mixture, a nozzle is mounted tangentially to the cylinder wall, which creates a stream of degassed liquid that rotates along the cylinder wall and is drawn through the nozzle from the liquid cavity at the cylinder outlet. However, the defoaming problem has not been solved in this design of the separator, the gas bubbles that make up the foam will be entrained both in the liquid discharge pipeline (introducing a significant fraction of free gas into the liquid stream) and in the gas discharge stream (introducing a noticeable liquid component into the sampled gas).
Пенообразование ведет к следующим проблемам: Foaming leads to the following problems:
- некорректная работа контрольно-измерительного оборудования (измерение расхода и количества основных компонентов смеси, температуры, измерение уровня и т.д.);
- для пен характерно большое отношение объема к массе, поэтому они могут занимать большое пространство в секциях сепаратора, которое при отсутствии вспенивания выполняло бы полезную функцию; - incorrect operation of instrumentation (measuring the flow rate and the amount of the main components of the mixture, temperature, level measurement, etc.); - foams are characterized by a large ratio of volume to mass, so they can occupy a large space in the sections of the separator, which in the absence of foaming would perform a useful function;
при неконтролируемом вспенивании невозможно произвести отбор выделившегося газа без уноса некоторого количества пены в линию выхода газа и отбор дегазированной нефти из сепаратора без увлечения некоторого количества пены в линию выхода жидкости. in case of uncontrolled foaming, it is impossible to take out the released gas without taking a certain amount of foam into the gas outlet line and take out the degassed oil from the separator without dragging some foam into the liquid outlet line.

Раскрытие изобретения Disclosure of invention
В процессе гравитационной сепарации, газожидкостную смесь подают в смесеприемную зону емкости. Вследствие падения давления в струе на выходе из подводящего патрубка и последующих динамических процессов, в растекающейся газожидкостной смеси происходит активное пенообразование. Одновременно в ту же зону, но выше и тангенциально стенкам под напором вводят поток(и) дегазированной жидкости, взятой с жидкостного выхода сепаратора, которая образует ниспадающий пристенный поток «мелкой воды», захватывающий и увлекающий пену через кольцевой зазор по стенке емкости в отстойную зону. При этом пена в большей части разрушается; дальнейшее разрушение пены происходит по мере ее накопления и сжатия в свободном пространстве отстойной зоны. Обратному движению пены препятствует перегородка с кольцевым зазором по стенке емкости и ниспадающие потоки жидкости, омывающие стенки емкости. Свободный газ, выделенный из разрушенной пены, возвращается в смесеприемную зону емкости через трубчатые каналы в перегородке, выступающие над потоком газожидкостной смеси и отводится через выход газа в верхней части емкости. Жидкость отводят через соответствующий выход в нижней части емкости. In the process of gravitational separation, the gas-liquid mixture is fed into the mixing zone of the tank. Due to the pressure drop in the jet at the outlet of the inlet pipe and subsequent dynamic processes, active foaming occurs in the spreading gas-liquid mixture. At the same time, in the same zone, but above and tangentially to the walls under pressure, a stream (s) of degassed liquid taken from the liquid outlet of the separator is introduced, which forms a flowing wall stream of “shallow water” that captures and entrain the foam through the annular gap along the wall of the tank into the settling zone . In this case, the foam is mostly destroyed; further destruction of the foam occurs as it accumulates and contracts in the free space of the settling zone. The backward movement of the foam is prevented by a partition with an annular gap along the wall of the tank and flowing down fluid flows washing the walls of the tank. The free gas released from the destroyed foam is returned to the mixing zone of the tank through tubular channels in the partition, protruding above the gas-liquid mixture stream and is discharged through the gas outlet in the upper part of the tank. The liquid is drained through the corresponding outlet at the bottom of the tank.
Осуществление изобретения The implementation of the invention
Способ и устройство проиллюстрированы чертежами фиг.1 и фиг.2. The method and device illustrated in the drawings of figure 1 and figure 2.
Фиг. 1 показывает движение газожидкостного потока, жидкости, газа и пены в схематично изображенном · пространстве гравитационного сепаратора 1. Поток газожидкостной смеси 2, введенный в емкость по подводящему патрубку, падает на перегородку 3 между смесеприемной 4 и отстойной 5 зонами. Активное пенообразование происходит в смесеприемной зоне 4. Одновременно в ту же зону, но выше и тангенциально стенкам под напором вводят поток(и) дегазированной жидкости, взятой с выхода сепаратора, которая образует ниспадающий пристенный поток дегазированной жидкости, взятой с выхода сепаратора. Пристенный поток увлекает пену через кольцевой
зазор 6 в отстойную зону 5. При этом пена в большей части разрушается; дальнейшее разрушение пены происходит по мере ее накопления и сжатия в свободном пространстве отстойной зоны 5. Освободившийся газ выходит через каналы 7 в перегородке 3 обратно в смесеприемную зону. Газ отбирают из верхней части смесеприемной зоны 4. FIG. 1 shows the movement of a gas-liquid stream, liquid, gas and foam in the schematically shown space of a gravity separator 1. The gas-liquid mixture stream 2, introduced into the container through the inlet pipe, falls onto the partition 3 between the mixing chamber 4 and the settling zone 5. Active foaming occurs in the mixing zone 4. Simultaneously, a stream of degassed liquid taken from the outlet of the separator is introduced into the same zone, but above and tangentially to the walls under pressure, which forms a flowing wall stream of degassed liquid taken from the outlet of the separator. Wall flow carries foam through the annular a gap 6 in the settling zone 5. In this case, the foam is destroyed for the most part; further destruction of the foam occurs as it accumulates and contracts in the free space of the settling zone 5. The released gas exits through the channels 7 in the partition 3 back to the mixing zone. Gas is taken from the upper part of the mixing zone 4.
Конструктивное решение емкости гравитационного сепаратора 1 , реализующее способ по настоящему изобретению, заключается в том, что емкость содержит перегородку 3 между смесеприемной 4 и отстойной 5 зонами с кольцевым зазором 6 по стенке емкости, на некоторой высоте от перегородки 3 размещен подводящий патрубок газожидкостной смеси. Как показано на фиг. 1 и 2, на стенке емкости в смесеприемной зоне 4 установлены тангенциальные штуцеры дегазированной жидкости 8 и 9, перекачиваемой насосом 10 с жидкостного выхода сепаратора в смесеприемную зону 4 емкости по возвратному контуру 11 , в который включен регулирующий кран 12. В перегородке 3 имеются каналы 7 для отвода свободного газа. A constructive solution of the tank of the gravitational separator 1 that implements the method of the present invention is that the tank contains a baffle 3 between the mixing chamber 4 and the settling zone 5 with an annular gap 6 along the wall of the tank, at a certain height from the baffle 3 there is an inlet pipe of the gas-liquid mixture. As shown in FIG. 1 and 2, tangential fittings of degassed liquid 8 and 9 are installed on the wall of the tank in the mixing zone 4, pumped by the pump 10 from the separator's liquid outlet to the mixing zone 4 of the container along the return circuit 11, into which the control valve 12 is connected. There are channels 7 in the partition 3 for removal of free gas.
Кран 13 открывает выход дегазированной жидкости из сепаратора для измерения ее количества перед использованием в дальнейшем технологическом процессе, а также для частичного возврата на вход сепаратора - для использования в процессе разрушения пены. Кран 14 открывает выход газу, который отводят из верхней части емкости сепаратора 1 с последующим измерением его количества. Crane 13 opens the outlet of the degassed liquid from the separator to measure its amount before use in a further process, as well as to partially return to the separator inlet for use in the process of foam destruction. The valve 14 opens the gas outlet, which is diverted from the upper part of the separator tank 1 with subsequent measurement of its quantity.
На фиг. 1 схематично показан ввод потоков дегазированной жидкости в сепаратор 1 в двух точках 8 и 9 (один из возможных вариантов). Соответствующий вариант конструктивного исполнения узла распределения возвратных потоков жидкости на входе в емкость сепаратора показан на фиг. 2. Здесь возвратный поток, поступающий по трубопроводу 11 , разводится через тройник 15 к штуцерам 8 и 9, вводящим потоки в емкость сепаратора 1 тангенциально его стенке в диаметрально противоположных точках.
In FIG. 1 schematically shows the introduction of flows of degassed liquid into the separator 1 at two points 8 and 9 (one of the possible options). A corresponding embodiment of the unit for distributing return flows of liquid at the inlet to the separator tank is shown in FIG. 2. Here, the return flow coming through the pipe 11, is routed through a tee 15 to the fittings 8 and 9, introducing flows into the capacity of the separator 1 tangentially to its wall at diametrically opposite points.
