Description

Technical Field

[0001] This utility model relates to the field of metering device technology, specifically to an improved integrated separate metering device. Background Technology

[0002] In the process of oil and gas extraction and processing, it is necessary to separate and measure the produced mixture. Existing separation and metering devices usually set up the separation and metering functions separately, resulting in large equipment size, high cost, and the separation efficiency and metering accuracy need to be improved.

[0003] For example, Chinese Patent No. CN202322396823.8 discloses a three-phase separation and metering device for oil, gas, and water in an oil and gas field. This patent includes a mixed liquid inflow pipe; a separation box, the side of which is fixedly connected to the mixed liquid inflow pipe; a gas conduit, which is fixedly connected to the top of the separation box; a water conduit, which is located at the bottom of the separation box; an oil conduit, which is fixedly connected to the top of the separation box; a heating ring, which is fixedly sleeved on the outer surface of the oil conduit; an anti-clogging feeding assembly, which is fixedly connected to the oil conduit; and metering devices, which are respectively located in the middle of the gas conduit, water conduit, and oil conduit. In the above scheme, the mixed liquid inflow pipe, separation box, gas conduit, water conduit, oil conduit, heating ring, temperature sensor, processing terminal, and anti-clogging feeding assembly are provided to achieve the effect of making the oil reach a suitable temperature and preventing it from becoming too viscous. Therefore, it is beneficial to separate oil, gas, and water. However, in actual use, the oil tank cannot effectively guarantee that the oil it introduces is pure oil, as it will contain a small amount of water, which leads to poor purity of the oil extracted later.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 An improved integrated separation and metering device includes a separation box 1. The upper left side of the separation box 1 is provided with a mixing medium inlet pipe 2, the top right side is provided with a first exhaust pipe 3, the bottom right side is provided with a drain pipe 4, and the bottom middle position is provided with a first oil drain pipe 5.

[0023] An oil tank 6 is provided inside the separator 1. One end of the first oil drain pipe 5 is connected to the oil tank 6, and the other end is connected to a secondary oil-water separator 7. The inner wall of the secondary oil-water separator 7 is provided with multiple heating rods 8. A second exhaust pipe 9 is provided at the top of the secondary oil-water separator 7, and a second oil drain pipe 10 is provided at the bottom. A temperature sensor is installed inside the secondary oil-water separator 7 to monitor the oil temperature.

[0024] In this embodiment, the second oil drain pipe 10 is located at the bottom of the secondary oil-water separator 7 at the end away from the first oil drain pipe 5, and a plurality of baffle plates 11 are spaced apart at the bottom inside the secondary oil-water separator 7.

[0025] The advantage of the above-mentioned structural design in this embodiment is that when the oil obtained by the first separation of the mixture flows into the secondary oil-water separator 7 from the first oil drain pipe 5, the oil will not flow directly into the second oil drain pipe 10. Instead, the oil will flow into the bottom of the secondary oil-water separator 7 and gradually flow towards the second oil drain pipe 10 under the obstruction of the baffle plate 11. This allows the oil to have sufficient contact time with the heating rod 8, so that the remaining water in the oil is fully heated and vaporized before being discharged from the second exhaust pipe 9.

[0026] In this embodiment, flow meters 13 are installed on the first exhaust pipe 3, the second exhaust pipe 9, the second oil drain pipe 10, and the drain pipe 4, so as to facilitate the measurement of the flow rate of gas, oil, and water.

[0027] A partition 14 is provided inside the separator 1 and on the right side of the first oil pipe 5, and a water tank 15 is formed between the partition 14 and the inner wall of the separator 1.

[0028] In this embodiment, a baffle plate 16 is fixedly connected to the inside of the separation tank 1 and to the left of the first oil drain pipe 5 by a wire. The surface of the baffle plate 16 is uniformly provided with flanges, and the baffle plate 16 can effectively reduce the sloshing of the liquid in the separation tank 1.

[0029] In this embodiment, a guide plate 17 is provided on the inner wall of the separation tank 1 corresponding to the port of the mixing medium inlet pipe 2. The guide plate 17 includes a vertical plate 171, a folding plate 172 at the bottom end of the vertical plate 171, and a support plate 173 on the rear side of the vertical plate 171 connected to the inner wall of the separation tank 1, thereby enhancing its structural strength. When the mixed liquid flows in from the first mixing medium inlet pipe 2, it is blocked by the guide plate 17, which firstly reduces the flow rate of the mixed liquid and secondly prevents the mixed liquid from being sprayed too far, thereby ensuring the separation effect of oil, water and gas.

[0030] In this embodiment, the separation box 1 is provided with a filter assembly 18 connected to the bottom end of the first exhaust pipe 3, and the gas can be filtered through the filter assembly 18.

[0031] In this embodiment, a heating sleeve 19 and a temperature sensor (not shown in the figure) are fitted onto the first oil drain pipe 5. The heating sleeve 19 heats the oil in the first oil drain pipe 5 to maintain its fluidity, thereby facilitating oil discharge. The temperature sensor is used to monitor the oil temperature, allowing for adjustment of the heating temperature of the heating sleeve 19.

[0032] In this embodiment, a processing terminal (not shown in the figure) is provided on the separation box 1, and the heating sleeve 19, temperature sensor and heating rod 8 are all electrically connected to the processing terminal.

[0033] Working principle:

[0034] The mixture enters the separation tank 1 through the mixing medium inlet pipe 2. Blocked by the guide plate 17, the mixture falls to the bottom of the separation tank 1 and slowly accumulates. Due to density differences, gas is discharged through the first exhaust pipe 3. Oil enters the oil tank 6 and is discharged through the first oil drain pipe 5, while water enters the water tank 15 and is discharged through the drain pipe 4. The heating jacket 19 is activated to heat the oil flowing into the first oil drain pipe 5. A temperature sensor detects the oil temperature and transmits the signal to the processing terminal, which controls the start and stop of the heating jacket 19. The oil enters the secondary oil-water separation tank 7 through the first oil drain pipe 5. The oil flows to the bottom of the secondary oil-water separation tank 7 and gradually flows towards the second oil drain pipe 10 under the obstruction of the baffle plate 11. The processing terminal controls the heating rod 8 to operate, heating the oil so that the remaining water in the oil is fully heated, vaporized, and discharged through the second exhaust pipe 9. Simultaneously, the temperature sensor monitors the oil temperature and transmits the signal to the processing terminal, which controls the start and stop of the heating rod 8. Finally, the oil is discharged from the second drain pipe 10.

[0035] Compared with the prior art, the technical solution of this application can perform secondary separation of oil-water mixtures, thereby improving the purity of the separated oil.

[0036] In another embodiment, condensers 12 are installed on both the first exhaust pipe 3 and the second exhaust pipe 9. The condensers 12 reduce the water in the gas back to liquid, facilitating subsequent collection and processing.
