Description

Technical Field

[0001] This invention relates to the field of oilfield development technology in the petroleum industry, specifically to a node management method and system for an oil and gas production system. Background Technology

[0002] In oil well production measurement and management, problems arise due to the simplification and optimization of surface process pipelines and limitations in measurement methods. These problems include measurement errors at the individual well and block system levels; the need for manual well location when system production changes; and the lack of a mechanism to establish a link between individual wells and the system. Production data is stored in a database on a server, and staff typically view it in tabular form, failing to provide a clear understanding of crude oil production and transportation. To address these issues, it is necessary to analyze the factors causing production variations and research effective solutions to reduce system and individual well measurement errors, thereby providing accurate data for oilfield development.

[0003] Current production data is primarily presented in tabular form, categorized by reservoir blocks and operating areas. However, this approach lacks a clear and timely overview of each well's specific production status, the assigned site for the produced crude oil, and key monitoring data during oil transportation, thus lacking a comprehensive crude oil production display platform. Currently, well production management relies heavily on manual statistical analysis. This method is significantly affected by technical limitations and the uncertainty of the analysis results, potentially leading to data bias. Furthermore, this analytical approach fails to consider the influence of factors such as process flow and regional distribution, limiting the guidance of the analysis results for practical field applications.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Figure 1 A flowchart of a node management method for an oil and gas production system provided in an embodiment of the present invention is shown below. Figure 1 As shown, the node management method of this oil and gas production system includes:

[0028] Step S101: Determine the sub-node management topology diagram of the oil and gas production system, wherein the sub-node management topology diagram includes the hierarchy and connection relationship of each node.

[0029] Specifically, an oil and gas production system includes nodes such as individual oil wells, metering stations, transfer stations, operating areas, and plant-level systems. An individual oil well is the basic unit for extracting oil and gas in an oil and gas field, allowing underground oil and gas to be extracted to the surface. Metering stations collect data from each individual oil well, including fluid volume, oil volume, water cut, dynamometer card production calculations, and correction factors. Typically, one metering station manages node data from multiple individual oil wells. Transfer stations connect different pipelines or networks to facilitate the transportation, transfer, and distribution of oil and gas. The output from multiple metering stations may be converged at a single transfer station, and then distributed, transferred, or further processed as needed. An operating area refers to the region within an oil and gas field where production operations take place, including multiple oil wells and production facilities. Operating areas typically cover a large geographical area and may contain multiple transfer stations connecting different pipelines or networks to facilitate the transportation, transfer, and distribution of oil and gas. Plant-level typically refers to an oil and gas production plant, which is the unit responsible for managing and operating production facilities and work areas. A plant-level unit is usually responsible for the production management, data collection and analysis, and production planning and execution of multiple work areas. Nodes in an oil and gas production system may also include oil collection points, which are used to transport crude oil by vehicle and are at the same level as metering stations. Therefore, the hierarchical order of nodes in an oil and gas production system from low to high is: single oil well, metering station (or oil collection point), transfer station, work area, plant-level. A topology diagram can be drawn based on the graphical development module of the force control software. The topology diagram displays the independence and interrelationships of single oil wells, valve components, stations, and various areas of the oil production plant, such as... Figure 2 This is a schematic diagram of the node management topology of an oil and gas production system provided in an embodiment of the present invention.

[0030] Step S102: Obtain data for each node of the oil and gas production system and construct a corresponding database according to the sub-node management topology diagram.

[0031] Specifically, the data for each node in the oil and gas production system is first acquired. In addition to the node identifier, each node data includes other parameters. For example, the node data for a single oil well includes at least one of the following parameters: liquid volume, oil volume, water content, dynamometer card production calculation, and correction coefficient. Similarly, the node data for a transfer station includes at least one of the following parameters: external transmission pressure, temperature, flow rate, oil storage tank level, and abnormal oil storage tank level. Then, a classification database consistent with the topology diagram structure is established through the force control software database configuration template database.

[0032] Step S103: Associate the node data in the database with the corresponding nodes in the sub-node management topology diagram and display them on the display interface.

[0033] Specifically, data points on the topology map can be linked in the ForceControl software development interface, presenting all topological relationships and data points on the software's running interface.

[0034] Step S104: Receive user operations on target nodes in the sub-node management topology map, and extract corresponding node data from the database for processing.

[0035] In some embodiments, step S104 includes at least one of the following: receiving a user's trigger operation on a metering station and displaying the node data of a single oil well under the metering station; receiving a user's trigger operation on a transfer station and displaying the node data of the metering station under the transfer station; receiving a user's trigger operation on a work area and displaying the node data of the transfer station under the work area; receiving a user's trigger operation on the plant level and displaying the node data of the work area under the plant level. Figure 3 As shown

[0036] Specifically, internal links are added to target nodes in the topology map, such as icons for work areas, transfer stations, and valve groups. Users can click to jump to the corresponding level and quickly view the relevant data. For example, oil wells are categorized and summarized by metering station, and a centralized topology map of individual wells is displayed. Figure 3 This invention provides a schematic diagram of node data display for a single well at a metering station. Metering stations and oil extraction points are categorized and centrally displayed by transfer stations. Transfer stations are categorized and centrally displayed by work areas. Work areas are then aggregated to the plant level. Plant-level data can be viewed at the top, and individual production data for each well can be viewed at the bottom, ensuring the comprehensiveness of data collection.

[0037] In some embodiments, the method further includes receiving real-time update operations from users on node data in the database. Specifically, the node data is categorized and established in the database, and can be read and written, supporting online updates and achieving real-time data performance.

[0038] The node management method for oil and gas production systems provided in this embodiment constructs a categorized database based on the hierarchical relationship of each node in the oil and gas production system by collecting data from each node, and links the data of each node in the database with the topology map. This allows users to click on the corresponding target node to jump to the corresponding level and display the corresponding node data, thereby realizing comprehensive and hierarchical statistics, display and processing of oil and gas production data and providing an effective management method.

[0039] Based on the aforementioned embodiments, Figure 4 A flowchart of another node management method for an oil and gas production system provided in an embodiment of the present invention further includes the following steps:

[0040] Step S401: Determine the target parameters associated with the production output of a single oil well based on the node data of the single oil well in the database.

[0041] Step S402: Construct a prediction model between target parameters and single-well production of oil wells, and optimize the target parameters of single-well oil wells based on the prediction model.

[0042] Specifically, after constructing a classification database for the oil and gas production system, the main parameters affecting the production of a single oil well are analyzed by combining the node data of the oil well. Then, coefficient correction and big data analysis methods are applied to establish a prediction model between the target parameters and the production of the oil well. This prediction model is then used to optimize the target parameters of the oil well.

[0043] Based on the aforementioned embodiments, target parameters associated with the production output of a single oil well are determined according to the node data of the oil well in the database; a prediction model between the target parameters and the production output of a single oil well is constructed, and the target parameters of the oil well are optimized according to the prediction model; this process enables the identification of the main factors affecting oil well production, and the adjustment and optimization of these factors to improve the production efficiency and performance of the oil well; this process can help staff better understand the operation of the oil well, optimize the production process, and improve production efficiency and output.

[0044] Based on the aforementioned embodiments, Figure 5 The flowchart of another node management method for an oil and gas production system provided in this embodiment of the invention further includes the following steps:

[0045] Step S501: Receive the alarm threshold settings of the first parameter of the transfer station in the database from the user. The first parameter includes at least one of the following: external pressure, temperature, and flow rate.

[0046] Step S502: If the first parameter exceeds the corresponding alarm threshold, a tiered alarm reminder will be displayed on the screen.

[0047] Step S503: Receive the user's setting or modification of the alarm threshold of the second parameter of the transfer station on the display interface. The second parameter includes at least one of the following: oil tank level and abnormal oil tank level.

[0048] Step S504: If the second parameter exceeds the corresponding alarm threshold, a tiered alarm reminder will be displayed on the screen.

[0049] Specifically, alarm thresholds are set for parameters such as external pressure, temperature, flow rate, and oil storage tank level at the transfer station. If these parameters exceed the alarm threshold range, the corresponding parameter will be highlighted in a different color on the display page to indicate that the data is abnormal and requires special attention. Furthermore, the alarm thresholds for external pressure, temperature, and flow rate at the transfer station are set in the database, while the alarm thresholds for the oil storage tanks can be modified on the display interface. Different colors are used for low alarm, high alarm, and very high alarm ranges to quickly identify and distinguish the type of alarm when abnormal data exceeds the threshold.

[0050] Based on the aforementioned embodiments, alarm thresholds for the external pressure, temperature, and flow rate of the transfer station are set in the database, and alarm thresholds for the storage tanks are set on the display interface. When the relevant parameters exceed the set thresholds, a tiered alarm notification is displayed on the interface so that staff can quickly identify abnormal situations.
