However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0048] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and thus their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware units or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0049] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the steps. For example, some steps may be decomposed, while some steps may be combined or partially combined, so the actual execution order may change according to the actual situation.

[0050] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0051] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or sub-modules is not necessarily limited to those steps or sub-modules explicitly listed, but may include other steps or sub-modules not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0052] This embodiment designs a unified online data reporting system for the needs of overseas project production management, which meets the reporting requirements at different stages and solves the management issues of project reporting authority and reporting content. This embodiment stores Excel (xlsx) format data and database structured data at the same time, designs each type of reporting content separately, and forms a universal reporting system.

[0053] Figure 1 is a flow chart of an online reporting method for oil and gas data of this exemplary embodiment. Figure 1 As shown, an exemplary embodiment of the present disclosure provides an online reporting method for oil and gas data, comprising:

[0054] S1 generates corresponding data reporting forms based on different oil and gas data;

[0055] S2 sets a corresponding storage process for each data reporting form, so that each type of oil and gas data is automatically structured and stored in the database according to the corresponding storage process;

[0056] S3 manages reporting permissions according to user attributes, and associates the reporting permissions corresponding to each user attribute with the data reporting form;

[0057] When S4 fills in data, it matches the corresponding data filling form according to the filling authority corresponding to the attributes of the currently logged-in user for the currently logged-in user to fill in.

[0058] In order to ensure the security of data and the convenience of viewing, this embodiment has designed a dual-media storage function. When the system fills in the Excel (xlsx format) report form, the system starts the user's local Microsoft Excel software and runs the report form. The user fills in the corresponding data in Excel. After the report is completed, the system automatically saves the Excel file on the server and performs automatic structural processing on the Excel table data and stores it in the database. This ensures that the Excel table and the database exist at the same time. If the data on one side is damaged, it will not affect the data security. At the same time, the Excel format data conforms to the user's usage habits, and the user experience is better.

[0059] For example, since the reporting is based on an Excel spreadsheet, by separating the reporting interface and the stored procedure, after the reporting form is designed, the corresponding stored procedure is written in the underlying database. The stored procedure can structure the contents of the Excel spreadsheet and store them in the database. By specifying the stored procedure to be called in the module, customized management of the reporting task can be achieved.

[0060] Exemplarily, the reporting authority is managed at three levels: department, role, and account. At the same time, detailed reporting authority is specified for each oil and gas project to achieve refined management of the reporting authority for each project.

[0061] Exemplarily, the module can call the user's locally installed Mircosoft Excel through the Office plug-in to open the reporting data form stored on the server. The user can fill in the form in the Excel interface. The reporting form has a built-in save button, and the Excel file can be saved on the server after clicking it.

[0062] Specifically, it includes:

[0063] After filling in the S5 data, submit the filled data report form to the approval module through the submission module;

[0064] The S6 approval module matches the approval personnel with review authority according to the data reporting form to approve the filled data reporting form;

[0065] S7 When there is no abnormality in the filled-in data reporting form, the stored procedure corresponding to the currently filled-in data reporting form is called to convert the currently filled-in data reporting form into structured data and store it in the database.

[0066] For example, after the user submits the reported data, the reviewer can view the reported data form in the system and make a preliminary manual judgment. If any abnormal data is found, the submitted data form can be returned to the person who reported it. If no abnormal data is found, the user can click on the approval button and the system will call the preset stored procedure to store the reported data in Excel in a structured manner into the database.

[0067] Specifically, it includes:

[0068] S8 calculates the structured data stored in the database, eliminates invalid data, and calculates the data according to the user's management standards.

[0069] For example, when data is stored in a database, secondary calculation is required to eliminate invalid data and calculate the data according to the user's management scope. For example, the original wellhead production data of oil and gas is converted into oil and gas commodity volume data, and some special symbols will also be eliminated.

[0070] Specifically, it includes:

[0071] S9 combines the structured data stored in the database with the historical data, automatically calculating and locating data anomalies.

[0072] For example, after the data is stored in the database, it needs to be compared and verified. The system automatically combines historical data with newly stored data. Since the oil and gas production data has continuity, the system automatically calculates and locates data that differs greatly from historical data, and automatically associates it with the original Excel report form, making it convenient for staff to compare and analyze and find data anomalies.

[0073] Specifically, it includes:

[0074] S10 stores the data reporting form in the server. When the data in the database corresponding to the data reporting form is damaged, the data reporting form stored in the server is called again and stored in the corresponding database to achieve data restoration.

[0075] Exemplarily, data storage is divided into two parts. One is the original data reporting form in Excel format, which is stored on the server to facilitate user viewing and analysis. At the same time, when the data in the corresponding database is damaged, the data can be re-entered and the damaged data can be restored.

[0076] Specifically, the user attributes include department, role and account number, and the data reporting form is in Excel format.

[0077] Figure 2 is a block diagram of an online reporting system for oil and gas data of this exemplary embodiment. Figure 2 As shown, an exemplary embodiment of the present disclosure provides an online reporting system for oil and gas data, comprising:

[0078] The task formulation module 10 is used to generate corresponding data reporting forms according to different oil and gas data;

[0079] The storage process setting module 11 is used to set the corresponding storage process for each data reporting form, so that each oil and gas data is automatically structured and stored in the database according to the corresponding storage process;

[0080] The authority management module 12 is used to manage the reporting authority according to the user attributes and associate the reporting authority corresponding to each user attribute with the data reporting form;

[0081] The data reporting module 13 is used to match the corresponding data reporting form for the currently logged-in user to fill in the data according to the reporting authority corresponding to the currently logged-in user's attributes.

[0082] In this embodiment, managers can freely customize the reporting form format and the stored procedures called according to business needs in the system, and the reporting content and form are more flexible. The reporting interface of the Excel data table is more in line with user habits. The dual-media storage form of Excel and database ensures data security to the maximum extent. If the data of one party is damaged, it will not affect the integrity of the overall data; the authority management function can carry out refined management and authority setting for the reporting personnel of each oil and gas project, ensuring the independence of the reporting of each project; the review and verification function guarantees the quality of data entry and the efficiency of locating errors and abnormal data. Because of the existence of the original Excel table, the difference between the stored data and the original data can be quickly compared, greatly reducing the cost of error checking and correction. Ultimately, data security management, efficient warehousing, and high-quality reporting are achieved.

[0083] Specifically, it includes:

[0084] The submission module 14 is used to submit the filled data report form to the approval module after the data is filled in;

[0085] Approval module 15, used to match the data filling form with an approval person with review authority to approve the filled data filling form;

[0086] The storage module 16 is used to call the storage process corresponding to the currently filled-in data reporting form when there is no abnormality in the filled-in data reporting form, convert the currently filled-in data reporting form into structured data, and store it in the database.

[0087] Specifically, it includes:

[0088] The intelligent computing module 17 is used to calculate the structured data stored in the database, eliminate invalid data, and calculate the data according to the user's management caliber.

[0089] Specifically, it includes:

[0090] The comparison and verification module 18 is used to combine the structured data stored in the database with the historical data, and automatically calculate and locate data anomalies.

[0091] Specifically, it includes:

[0092] The data storage module 19 is used to store the data reporting form in the server. When the data in the database corresponding to the data reporting form is damaged, the data reporting form stored in the server is called again and stored in the corresponding database to realize data restoration.

[0093] Specifically, the user attributes include department, role and account number, and the data reporting form is in Excel format.

[0094] Figure 3is a schematic diagram of the structure of the overseas online data reporting system of this exemplary embodiment; Figure 3 As shown, taking the customized overseas online data reporting system as an example, the system is designed to meet the needs of overseas oil and gas business production management data reporting, including task customization module, authority management module, data reporting module, submission and approval module, data storage module, intelligent calculation module, comparison and verification module, and data storage module. The following is an exemplary description of the functions of each module:

[0095] Task customization module 10: According to the needs of overseas oil and gas business, two types of data reporting forms are customized, namely dynamic analysis data reporting form and oil and gas reservoir development parameter status table, and corresponding storage procedures are specified for the two types of reporting forms to realize automatic structured storage of data;

[0096] Permission management module 12: Create an independent account for each project reporting person, assign a random password, and associate the data reporting form of each project with the person's account permissions to ensure that the project reporting forms are independent of each other, thereby ensuring data security and preventing leakage to the greatest extent possible.

[0097] Data reporting module 13: After the user logs in, the system matches the Excel form that needs to be reported based on the user's authority range. The user completes the reporting on the form and clicks Save. The Excel file is automatically saved on the server and the form is pushed to the approver.

[0098] Submit the approval module 20: The approver can view the Excel spreadsheet with what permissions according to the permissions. If any filling error is found, the spreadsheet can be returned to the person filling in the report; if it is confirmed that there is no abnormality in the filling content, you can click to pass, and the spreadsheet data will be automatically stored.

[0099] Data storage module 21: After the approval personnel confirms the approval, the system automatically calls the pre-set stored procedure to convert the data in the Excel table into structured data and store it in the database. If an Excel table has multiple sheets, it will be stored in different tables.

[0100] Intelligent computing module 17: To meet the needs of business research and analysis, after the original data is stored in the database, secondary calculation is required to generate oil and gas production data of overseas management caliber through derivative calculation, and the calculation result data is stored in the corresponding library table for subsequent reading and calling.

[0101] Comparison and verification module 18: After the data is stored in the database, it needs to be verified twice. The system will splice the historical data of each project with the latest reported data, and automatically locate data anomalies, so that the reviewers can quickly judge the accuracy of the newly entered data, compare it with the historical data, and determine the deviation range.

[0102] Data storage module 19: The module can manage Excel files stored on the server. If data modification is required later, the data can be saved in Excel and stored again, ensuring the recoverability of the data.
