Description

Technical Field

[0001] The utility model relates to the technical field of shale gas separation and metering, and more specifically to a manifold skid-mounted separation meter. Background Art

[0002] Oil and gas metering refers to the measurement of oil and natural gas flow. It is mainly divided into oil well production metering and external flow metering. Oil well production metering refers to the measurement of the amount of oil and gas produced by a single well. It is the key data for oil well management and understanding of oil layer dynamics. It is the first-hand data for reservoir dynamic analysis and directly affects the direction of reservoir development. Therefore, the accuracy of oil and gas metering is particularly important. Due to the influence of complex factors such as the properties of crude oil, differences in water content and gas content, and irregular production fluid, oil and gas metering has problems of complex structure and poor versatility in actual application. This problem is particularly prominent in oil wells with intermittent oil, little gas, and large fluctuations in liquid. When the amount of liquid is small, it is easy to have inaccurate measurement; when the amount of liquid is large, there is a problem of long control valve action time and easy flooding.

[0003] Prior art A patent document with publication number CN113931610A discloses a separation meter, which adopts a control cabinet connected with an intelligent magnetic flap level gauge, an oil inlet control valve, an oil outlet control valve, and a liquid pressure valve, and can realize automatic well selection, remote data transmission, and remote monitoring, thereby improving the intelligence and automation of oil and gas metering, reducing the workload of staff, and improving the efficiency of recording and monitoring metering data. However, each pipe fitting is set up in batches, and needs to be loaded and unloaded on site, which is not very convenient for transportation, and occupies a large area after connecting the entire set of equipment, which is not conducive to implementation in a limited space.

[0004] In order to overcome the defects existing in the above-mentioned prior art, the purpose of the utility model is to provide a manifold skid-mounted separation meter, which adopts a skid-mounted integrated manner to reduce transportation costs and installation costs, and reduce floor space.

[0030] Example 2

[0031] This embodiment is further described on the basis of the embodiment 1. The above-mentioned sewage pipeline 6 is provided with a pneumatic ball valve 601, an electromagnetic metering valve 602, a sewage inlet ball valve 606, a liquid level regulating valve 607 and a sewage outlet ball valve 608 from the inside to the outside.

[0032] As an implementation mode of this embodiment, the above-mentioned sewage pipeline 6 is also provided with a bypass pipeline, and the connection ports of the above-mentioned bypass pipeline are respectively arranged between the electromagnetic metering valve 601 and the sewage inlet ball valve 606 and between the sewage outlet ball valve 608 and the pipeline outlet, and the sewage ball valve 603 and the sewage gate valve 604 are arranged in sequence along the fluid flow direction.

[0033] As an implementation mode of this embodiment, a liquid level transmitter 7 and a local liquid level gauge 8 with local display are also provided on the side of the body of the above-mentioned separation meter 1. The above-mentioned liquid level transmitter 7 is interlocked with the liquid level control valve 607, and the liquid level transmitter 7 and the local liquid level gauge 8 with local display are provided at the same time. The design of the double liquid level gauge effectively reduces the fault tolerance and avoids the occurrence of failures. The interlocking design of the liquid level transmitter 7 and the liquid level control valve 607 can automatically control the valve opening according to the height of the liquid level surface without manual adjustment, which can improve the degree of automation, reduce labor intensity, and improve the stability of working conditions.

[0034] An outlet gate valve 303 is arranged at the outer port of the above-mentioned outlet pipeline 3, and a gas meter 301 and a thermometer 302 are arranged in sequence outward along the fluid flow direction on the outlet pipeline 3; the above-mentioned vent pipeline 4 is sequentially provided with a manual vent ball valve 404 and a vent ball valve 405 from the inside to the outside, and a safety pipeline is also arranged in parallel, the above-mentioned safety pipeline is connected to the auxiliary vent port arranged next to the vent port, and the other end of the safety pipeline is connected to the outside of the vent ball valve 405, and the above-mentioned safety pipeline is provided with a safety valve root gate valve 401, a spring-closed safety valve 402 and a vent outlet ball valve 403 from the inside to the outside.

[0035] As an implementation of this embodiment, a water injection port 101 and a maintenance port 102 are also provided on the separation meter 1.

[0036] As an implementation of this embodiment, a pressure detection device is provided, including a container pressure gauge 108 installed beside the maintenance port 102 of the separation meter body 1 and a sewage outlet pressure gauge 605 installed at the outer port of the sewage pipeline 6. An instrument control box container is also installed on the bottom skid. The container pressure gauge 108 monitors the pressure inside the pipe, and the sewage outlet pressure gauge 605 monitors the pressure of the sewage medium. The two pressure gauges and other transmitters are powered and operated by the instrument control box. Specific working principle:

[0037] The gas containing water and slag enters the separation meter 1 through the inlet gate valve 501. The separation meter 1 uses gravity, coalescence separation, cyclone separation and other separation methods to separate the liquid and solid in the gas. The clean gas reaches the downstream end through the gas outlet pipeline. If necessary, a gas meter 301 can be added to measure the gas. The water injection port 102 is used to inject water into the equipment before maintenance to eliminate safety hazards. The separated slag and liquid enter the electromagnetic metering valve 602 through the pneumatic ball valve 601 and are measured. Then they reach the sewage outlet through the sewage regulating valve inlet ball valve 606, sewage liquid level regulating valve 607, and sewage regulating valve outlet ball valve 608. The sewage liquid level regulating valve 607 automatically adjusts the liquid level according to the parameters of the liquid level transmitter 7. The sewage ball valve 603 and sewage gate valve 604 on the bypass pipeline discharge sewage when the sewage liquid level regulating valve 607 is overhauled.

[0038] The flow meter has its own installation standards. The front and rear straight pipe sections must be set to a certain length and have a certain distance from the next instrument or bend to ensure accurate measurement.

[0039] As an implementation method of this embodiment, the straight pipe distance between the electromagnetic metering valve 602 and the pneumatic ball valve 601 should be greater than 5D (D is the pipe diameter), the straight pipe distance between the bypass pipe and the front connection port of the vent pipe 4 should be greater than 3D, the straight pipe distance between the gas meter 301 and the gas outlet should be greater than 20D, and the straight pipe distance between the gas meter 301 and the nozzle of the thermometer 302 should be greater than 8D. The instruments on the pipeline have their own installation positions and installation distance requirements. If the requirements are met, the length of the connected pipeline cannot be reduced. Therefore, the sewage pipeline 6 and the vent pipe 4 connected to the separation meter 1 are installed along the body of the separation meter 1 until they reach the gas inlet end of the separation meter 1, extending to the boundary of the skid without exceeding the boundary of the skid. This method can effectively lay the length of the pipeline without affecting its use. The connecting pipeline will not exceed the space range of the entire skid, avoiding the expansion of the installation space and the expansion of the occupied area. This installation process not only meets the installation requirements but also saves floor space.

[0041] This embodiment further illustrates the present invention based on the above two embodiments. Figure 1 and Figure 2 As shown, for different separation metering devices 1 on the market, the connection methods of the venting pipeline 4 are different, but the effects are the same. Figure 1 The separation meter shown is provided with a vent port 104 and an auxiliary vent port, which are connected to the vent line 4 and the safety line respectively, and Figure 2 The effect of connecting a safety line in parallel to the vent line 4 is the same as shown.

[0043] This embodiment further illustrates the present invention based on the above embodiments.
