Description

The utility model relates to the oil industry and can be used in the preparation of well products in field conditions, as well as in the development of technological modes of preparation of well products in laboratory conditions.

State of the art

For the prototype of the proposed installation, a local separation installation was adopted (RF patent No. 170646, class IPC ЕВВ 43/34, published date 05/03/2017), consisting of a cylindrical tank, in the upper part of which, closer to one of the ends of which, G- shaped pipe for the input of the gas-oil mixture coming from the wells. Two vertical parallel partitions are installed inside the unit, and a continuous overflow vertical partition is installed closer to the output of the product. In the upper part of the tank there is a gas outlet pipe and a droplet eliminator. Perforated tubes with steaming pipes for steam supply during tank cleaning are installed in the bottom of the tank, and pipes for water drainage and dehydrated well production are also located. The disadvantage of this design is the impossibility of changing the internal configuration of the tank for studies of the separation of the gas-oil mixture.

Utility Model Implementation

The separation tank with paired partitions includes a horizontally oriented cylindrical tank 1, one of the side ends of which is made in the form of a cover 2 with the possibility of its installation-removal using a rotary device 3. On the side surface of the housing 1 there are inspection windows 4.

In the upper, lower and end parts of the housing 1 of the separation tank, there are installed nozzles 5 for supplying a gas-oil mixture of well products, a branch pipe for gas discharge 6, drain pipes 7, a pipe 8 for separating separated oil, a pipe 9 for installing a level gauge, a pipe 10 for installing a manometer.

Inside the tank 1 there are two identical pairs of transverse partitions. A pair of transverse partitions, located closer to the nozzles 5 for supplying the gas-oil mixture, includes a lower partition 11 and an upper partition 12 made in the form of two flat metal disks parallel to each other, installed in the cross section of the tank 1 and connected to it through the eyes by pairs of studs 13, 14 , 15 with the possibility of axial movement along them. Horizontal sections are made in the upper part of the lower partition 11 and in the lower part of the upper partition 12, forming gaps between them and the inner side surface of the container 1, hydraulically connecting the space in front of the lower partition 11 and the space behind the upper partition 12. The partitions 11 and 12 are interconnected with using elongated studs 14 with the possibility of axial movement along them.

The second pair of transverse baffles, placed in front of the outlet 8 for separating the separated oil, is made similar to a pair of baffles located in the inlet part of the tank 1, and includes a lower baffle 16 and an upper baffle 17 made in the form of two flat parallel to each other metal disks installed in cross section capacity 1 and connected to it through the eyes by pairs of pins 18, 19, 20 with the possibility of axial movement along them. Horizontal sections are made in the upper part of the lower partition 16 and in the lower part of the upper partition 17, forming gaps between them and the inner side surface of the container 1, hydraulically connecting the space in front of the lower partition 16 and the space behind the upper partition 17. The partitions 16 and 17 are interconnected with using elongated studs 19 with the possibility of axial movement along them.

The separation tank with paired partitions is as follows.

The flow of the water-gas-oil mixture containing the pre-degassed oil-water mixture coming from the wells, the reagent demulsifier and fresh water is directed to the inlet of one of the nozzles 5. If necessary, the gas component is directed to the discharge through the upper nozzle 6. The flow rate of the gas-oil-oil emulsion entering the tank 1 drops sharply, which helps to reduce the mixing of the mixture (reduce turbulence), strengthen the gravitational process and the separation of the gas-oil mixture into gas, oil and water composition components along the height of the cylindrical container 1. If necessary, a gas component is directed to vykid through pipe 6.

Passing through the upper gap of the lower baffle 11 and the lower gap of the upper baffle 12 of the first pair of transverse baffles, the flow path of the oil-gas mixture with the demulsifier further increases, the process of separation of the flow into the water and oil phases takes a longer time, while due to gravity sludge a heavier water the component accumulates in the lower part of the tank 1 and is partially discharged through one of the drainage pipes 7. The separation of the mixture between the partitions is observed visually with the help of viewing windows 4.

Partially dehydrated oil reaches the lower partition 16 of the second pair of partitions, through the gap in the upper part of the partition 16 and the gap in the lower part of the partition 17 accumulates behind the partitions, while the produced water is discharged through the pipe 7, and the dehydrated water-oil mixture is sent through the pipe 8, if necessary, to a desalination plant, or in a drainage tank - in the case of development of structural elements or studies of the characteristics of a new demulsifier. Visual monitoring of the process of separation of the water-gas mixture is carried out using windows 4 located diametrically to each other in the tank 1. The liquid level of the tank is monitored using a level gauge installed on the nozzle 9. The pressure in the tank is monitored using a pressure gauge installed on the nozzle 10.

In order to study the effect of the demulsifier reagent on the process of destruction of the oil-water emulsion, the length of the section of the turbulent flow formed at the inlet of the separation tank and the length of the section of the laminar flow formed in the central part of the separation tank are changed. To do this, change the distance between the pairs of partitions by moving the partition 11 along the studs 13, 14, the partition 12 along the studs 14, 15, the partition 16 along the studs 18, 19, the partition 17 along the studs 19, 20.

The design of a separation unit with paired partitions proposed for protection is successfully used in the fields of LUKOIL-PERM LLC and for research purposes of the Perm Scientific Research Polytechnic University (PNIPU).
