The invention relates to devices for the combined treatment of oil, associated gas and produced water, and can be used in the oil industry.

The closest to the invention to the technical essence and the achieved result is a device for the joint preparation of gas of oil and water, comprising a housing, non-fuser, tester, water collector, distributor, thin-layer plates, branch pipe for product input, branch pipes for oil output and water, inlet, separating and exit chamber fll. 15

The disadvantage of the device is that the day structure does not allow to remove sediments from it during operation, which leads to a reduction and durability of pipelines,. The 20 parts of the pump, valves, etc., which are directly connected with the pumping of liquid, worsen the operating conditions of the above means, as well as the equipment being on the MFR and FWSS, which leads to an increase in their repair and accidents, which are the cause of environmental pollution, the low utilization rate of the installation, which reduces the capacity of the installation, the flow of liquid is carried out below the water layer, which yxyrfuaeT separation process.

The aim of the invention is to improve the reliability, durability and performance of the device.

The goal is achieved by the fact that in a device for the joint preparation of gas, oil ji of water, comprising a housing, an oil sump, a water sump, a distributor, thin-layer plates, nozzles, an inlet, a separating and an outlet chambers, the housing is rectangular, equipped with bunkers located under each chamber and having drainage pipes with shut-off

fittings, a drop separator, a T-shaped pipeline, which connects the nozzle to drain water to the upper part of the body, thin-layer plates are installed in the upper and lower parts of the separating chamber throughout its area, the distributor is installed horizontally in the upper part of the inlet chamber throughout its width near the inlet end and It is made of a nozzle with plugged ends, with longitudinal, single-sided slits directed downwards to the entrance end of the chamber. The drawing shows a device for the joint preparation of gas, oil and water. The device consists of a housing 1, which is a hollow parallelepiped capacitance divided inside by partitions 2-5 into an input 6, separating 7 and output 8 chambers. Each chamber is provided at the bottom with bunkers 9, terminated by a nozzle 10, to which shut-off valves 11 are fixed to discharge the sediment. On the lids of the chambers, there is a drop separator 12 and a nozzle 13 for the discharge of gas. At the inlet end of the inlet chamber, a nozzle 1 is installed for introducing production, which is tangentially connected to the middle of the distributor 15 located in the upper part of the inlet chamber across its entire width horizontally near its inlet end and parallel to it. Moreover, the longitudinal multi-edged side slots of the distributor along its entire length, are directed downwards toward the entrance end of the chamber along its entire width. Removable countercurrent steeply inclined thin-layer plates (PCTP) 1b and 17 are installed in the upper and lower parts of the separating chamber along its length and width. An oil collector 18 and a branch pipe 19 are installed at the output end of the output chamber to discharge the purified oil, as well as the catchment basin 20 and the branch pipe 21 for the withdrawal of purified water. An L-shaped bar 22, a stop valve 23, T-pipe 2 and a shut-off valve 25, which is connected to an L-pipe 2b connected to the gas zone of the outlet chamber, are successively connected to the pipe for the discharge of purified water. The amount of incoming fluid (product), discharged purified water and refined oil is fixed with flow rates, which are impacted by

input and output lines; In the device, the oil level is controlled by changing the height of the oil collector 18, and the oil-water phase separation level 5 by changing the T-shaped pipeline 2, which makes it possible to obtain the required thickness of oil and water in the chambers and stabilize the separation process. The investigator’s oil level and the az section of the oil drive in the device are adjusted without the use of automation, which greatly simplifies the design, reduces the cost of the device and increases its reliability in operation. The device works as follows. The production of oil wells from the previous stages of separation plants through the pipeline and the pipe 1 enters the distributor 15, then from there it is directed down to the input end of the input chamber 6 over its entire width. The products, returning from the inlet end of chamber 6 at a significantly reduced speed and freely spreading through the inlet chamber 6, are separated into gas, oil, water, sand and mechanical impurities. Such product delivery to the chamber is most beneficial for pre-separation, which leads to an increase in the efficiency of the process. The gas, floating up, is separated from the liquid and discharged through pahrubok 13, passing through the separator 12, from which the captured liquid droplets fall into the liquid layer. Coarsely cleaned oil from the upper part of the inlet chamber 6 over its entire width through the partition 2 enters the separating chamber 7 above the upper SCTP 16. Coarsely purified water from the lower part of the inlet chamber 6 along its entire width, the passage between the partitions 2 and 3 enters the separating chamber 7 over bottom counterflow large-inclined thin-layer plates 17. Large sediments in the form of sand, mechanical impurities, etc. In the separating chamber 7, coarse raw oil falls, the passage from top to bottom in the counter-current direction through the upper SCTP 16, is cleared of gas, water, sand and mechanical impurities. When refining oil, the residual gas from the Upper SCPP 16 in an enlarged form pops up into the gas zone, and through the droplet separator 12 and the nozzle 13 is removed from chamber 7. Water, sand and mechanical impurities from the upper SCPT 1b in an enlarged form fall into the water and cleaned oil beneath the upper SCPT 16 horizontally moves to the outlet of the separating chamber 7. Thus, the oil in the separating chamber 7 is subjected to a Z-shaped movement before exiting it, and then at the outlet of the chamber along its entire width rises up between partitions and 5 and through fused In the separation chamber 7, coarsely purified water passes from top to bottom in a counter-current direction through the bottom SCTP 17 and is cleaned of gas, oil, sand and mechanical impurities. When purifying water, residual gas and oil from the bottom SCTP 17 are enlarged the form floats up and enters the oil layer: the oil, draining with the oil layer, is carried to the output chamber 8, and the gas, which floats upward from the oil, flows into the gas zone of the chamber, then through the suction separator 12 and the nozzle 13 is removed from cameras. Precipitation in the form of sand and mechanical impurities, etc. from the bottom SCTP 17 in an enlarged form fall out into the bunker 9, and the purified water under the bottom SCTP 17 horizontally goes to the outlet of the separating chamber 7. Thus, the water in the separating chamber 7 is subjected to a Z-shaped movement and then The passage of the separating chamber 7 along its entire width under the partition 5 enters the output chamber B. The embodiment of the separating chamber 7 in the described form and its combined use from the inlet 6 and the outlet 8 by the cameras allow pre-purified oil and water flows, save their connection with Mosto tion, ie, independently of each other, move along complex trajectories and finally be cleaned of all components, i.e. clean gas, water and sediments from oil, and gas, oil and sediment from water, and remove each component from the chamber separately. The removable design of the anti-tumor steeply inclined plates of the SCPT allows, during operation, if necessary, to change their material, the angle of inclination, the distance between them, etc. From the outlet chamber 8 over its entire width, the refined oil is removed through the oil tank 18 and the pipe 19, and the purified water is removed through the water collector 20, the pipe 21, the L-shaped pipe 22, the stop valves 23 and the T-shaped pipe 2. The residual gas, separated from the liquid, is removed from the chamber through the sump 12 and nozzle 13. The residual precipitates fall into the bunker 9 of the exit chamber 8. The sediment in the form of pulp is continuously removed from the silos 9 of chambers 6-8. From the description it is clear that the design of the output chamber allows the product to be divided into components, i.e. gas, oil, water and sediment, and withdraw each component separately. Thus, the volume of the device, i.e. the utilization rate of the device is increased, thereby increasing its productivity. At the same performance, the size and weight of the device, as well as the cost of building construction for its placement, decrease.
