Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method, apparatus and system for notifying data changes in the oil and gas sector. Background Technology

[0002] This section is intended to provide background or context for the embodiments of the invention set forth in the claims. The description herein is not an admission that it is prior art simply because it is included in this section.

[0003] With the development of internet technology, especially after the introduction of microservice architecture, the decoupling between services and the complexity of distributed systems have made data change notifications particularly important. Message queues (MQ) and event-driven architecture (EDA) have become common technologies for implementing data change notifications. Through the publish / subscribe pattern, services can subscribe to specific data change events and receive notifications when data changes, thereby triggering corresponding business logic. However, implementing data change notifications may lead to excessive resource consumption, such as frequent database queries or message passing. In the event of system failure or network problems, without a proper message notification mechanism, there is a risk of message loss.

[0004] Currently, most commonly used solutions employ a database polling method via API queries at a frequency agreed upon by both parties to synchronize and update data. However, this approach suffers from poor data real-time performance, making it difficult to meet the timeliness requirements of business users. Furthermore, as the query frequency increases, it can negatively impact database write performance, significantly affecting the data source. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0045] Figure 1 This is a flowchart of a data change notification method in the oil and gas sector, as described in this embodiment of the invention. The method is applied to various oil and gas sector data centers, each of which communicates with the oil and gas sector data service control system. The method includes:

[0046] Step 101: When an oil and gas data change event occurs, determine the current event change type;

[0047] Step 102: When the event change type is a notification-required type, generate an oil and gas sector event data body, which includes oil and gas sector data based on changes in the data exchange model type.

[0048] Step 103: Generate summary information for key fields of the oil and gas event data body using a hash function;

[0049] Step 104: Generate a data change request based on the oil and gas sector event data body, summary information, and the identity token of the oil and gas sector data center;

[0050] Step 105: Send the data change request to the oil and gas field data service control system. After the oil and gas field data service control system verifies the summary information and the identity token of the oil and gas field data center in the data change request, it verifies the changed oil and gas field data body in the data change request according to the data exchange model type. After the verification is passed, the oil and gas field data that meets the data discovery rules is sent to the corresponding oil and gas work area.

[0051] In this embodiment of the invention, data changes based on an event mechanism require determining the type of event change. Data processing only occurs when a notification type is required. To improve data push efficiency and security, oil and gas sector data is encapsulated into an oil and gas sector event data body, and the oil and gas sector data is based on a data exchange model type. To further enhance the security of data transmission, a dual protection method using summary information and identity tokens is employed. After receiving a data change request, the oil and gas sector data service control system verifies it and, upon successful verification, sends oil and gas sector data that conforms to the data discovery rules to the corresponding oil and gas work area, thus achieving targeted push for oilfield work areas.

[0052] Each step is described in detail below.

[0053] This invention supports two push modes: active push mode and passive refresh mode. In active push mode, data changes (such as additions, deletions, and modifications) are actively pushed to the respective oil and gas data centers. Passive refresh mode serves as a compensation mechanism for active push mode; in the event of unexpected situations such as data transmission interruptions or network problems, the oil and gas data service control system sends data push commands to each oil and gas data center.

[0054] Steps 101-105 specifically address the proactive push mode. The proactive push mode employs an event processing principle based on data event rules. Figure 2 This is a schematic diagram of the event processing principle based on data event rules in an embodiment of the present invention. In this embodiment, the event refers to an oil and gas data change event. Time change type filtering refers to judging the current event change type and filtering out the exchange data corresponding to oil and gas data change events with the event change type of "needing notification".

[0055] In step 101, when an oil and gas data change event occurs, the current event change type is determined;

[0056] The oil and gas sector encompasses seismic, logging, drilling and completion, pipeline, reservoir, and integrated management fields. Data change events in the oil and gas sector include object events, container events, and data events. The addition, modification, and deletion of object events, the addition and removal of container events, and all data event changes are considered notification-required types. Taking the seismic sector as an example, notification-required types specifically include changes to project and work area object types supporting objects and data events, as well as changes to seismic data, 3D horizons, and 3D faults supporting containers, objects, and data events.

[0057] In step 102, when the event change type is a notification-required type, an oil and gas sector event data body is generated, which includes oil and gas sector data based on changes in the data exchange model type.

[0058] In one embodiment, the oil and gas field event data body further includes at least one of data version, data exchange model type, event identifier, event occurrence time, data source, and data type.

[0059] The format of event data in the oil and gas sector is shown in Table 1.

[0060] Table 1

[0061]

[0062] According to Table 1, event data in the oil and gas sector can be identified using JSON format.

[0063] In step 103, a summary information is generated for the key fields of the oil and gas event data body using a hash function. Specifically, the key fields can be determined according to the actual situation. In this embodiment of the invention, the key fields include data version, data exchange model type, and oil and gas data based on changes in the data exchange model type.

[0064] In step 104, a data change request is generated based on the oil and gas sector event data body, summary information, and the identity token of the oil and gas sector data center;

[0065] In one embodiment, before sending the data change request to the oil and gas sector data service control system, the method further includes:

[0066] When the size of the data change request exceeds a first preset data size, the data change request is converted into a binary data serialization format;

[0067] When the size of a data change request in binary data serialization format exceeds the second preset data size, a lossless compression algorithm is used to compress the data change request in binary data serialization format.

[0068] The compressed data change requests are stored in a memory-based queue;

[0069] A multi-threaded asynchronous program is used to send compressed data change requests from a memory-based queue to the oil and gas data service control system.

[0070] Specifically, in scenarios involving large-scale data changes, to optimize message generation and transmission efficiency, a binary data serialization format can be used. After format conversion, data can be compressed into a more compact binary form, thereby reducing the amount of data transmitted over the network. The binary data serialization format is marked with, for example, `application / vnd.apache.avro.binary+json` so that the receiver can correctly identify and decode the data. This method not only improves data transmission efficiency but also leverages powerful schema support, making the data structure more explicit and easier to manage.

[0071] For cases involving very large datasets, such as seismic data volumes or reservoir model data volumes, lossless compression algorithms like Deflate and Snappy can be used to compress data change requests in binary serialized data formats. The receiving end then decompresses the data before use. (Seismic data volumes can be sliced ​​using VDS technology, creating gather slices along longitudinal or connecting survey lines, or along the time direction, for fragmented transmission. Reservoir model data volumes can be thinned according to the model mesh.) Furthermore, concurrent processing methods can be considered, using memory-based queues like Disruptor. This high-performance, lock-free queue uses a circular buffer in memory to store messages, and then uses a multi-threaded asynchronous program to batch process data, achieving high throughput and low latency data transfer. Additionally, memory-based queues can avoid lock contention by pre-allocating memory, thereby improving concurrent processing capabilities.

[0072] In one embodiment, a multi-threaded asynchronous program is used to send compressed data change requests from a memory-based queue to an oil and gas data service control system, including:

[0073] The multi-threaded asynchronous program actively invokes the data change service of the oil and gas field data service control system, and pushes compressed data change requests from a memory-based queue to the oil and gas field data service control system.

[0074] In step 105, the data change request is sent to the oil and gas field data service control system. After the oil and gas field data service control system verifies the summary information and the identity token of the oil and gas field data center in the data change request, it verifies the changed oil and gas field data body in the data change request according to the data exchange model type. After the verification is passed, the oil and gas field data that meets the data discovery rules is sent to the corresponding oil and gas work area.

[0075] The inventors discovered that, in addition to the existing solutions employing an active push mode, data compensation mechanisms are not adequately considered in the event of unexpected situations during data transmission, leading to data loss or incompleteness. Therefore, embodiments of this invention also propose a passive refresh mode.

[0076] In one embodiment, the method further includes:

[0077] After receiving a data push command from the oil and gas data service control system, query the data within the time range specified in the data push command.

[0078] Based on the version change information of the retrieved data, obtain incremental data;

[0079] The generated data change request is sent to the oil and gas field data service control system through the passive refresh interface of the oil and gas field data service control system.

[0080] Specifically, in the passive refresh mode described above, incremental data is pushed through the passive refresh interface. The passive refresh interface is described in Table 2.

[0081] Table 2

[0082]

[0083]

[0084] In the above process, incremental data is obtained based on the version change information of the queried data. For example, the business primary key is composed of fields such as the business department of the oilfield enterprise and the batch time of the processing and interpretation as version information. Whether incremental synchronization is triggered is inferred based on the version change information.

[0085] Both the active push mode and the passive refresh mode have two ways of sending data content, including single data push and batch data push.

[0086] This invention also proposes a method for notifying data changes in the oil and gas sector. Figure 3 This is a flowchart of another oil and gas sector data change notification method according to an embodiment of the present invention. The method is applied to an oil and gas sector data service control system, which communicates with multiple oil and gas sector data centers. The method includes:

[0087] Step 301: Receive a data change request sent by the oil and gas domain data center; the data change request is generated by the oil and gas domain data center when an oil and gas domain data change event occurs and the event change type is a notification-required type, based on the changed oil and gas domain data; the data change request includes an oil and gas domain event data body, summary information, and an identity token of the oil and gas domain data center; the summary information is generated by a hash function on the key fields of the oil and gas domain event data body; the oil and gas domain event data body includes the changed oil and gas domain data based on the data exchange model type.

[0088] In one embodiment, after receiving a data change request from an oil and gas data center, the method further includes:

[0089] If the data change request is in compressed format, decompress the received data change request;

[0090] If the decompressed data change request is in binary serialized format, convert the decompressed data change request into the original format of the oil and gas data center.

[0091] Step 302: Verify the identity token of the oil and gas data center;

[0092] Each oil and gas data center has its own identity token to verify its identity and ensure the security of its data services.

[0093] Step 303: After verification, generate summary information based on the oil and gas field event data body in the received data change request;

[0094] Step 304: Compare the generated summary information with the summary information in the received data change request;

[0095] Step 305: After successful comparison, verify the event data body in the oil and gas field;

[0096] In one embodiment, the verification of oil and gas sector event data includes:

[0097] The first verification is performed on the oil and gas sector where the event data body is located.

[0098] After the first verification passes, a second verification is performed on the relationship between the data exchange model type and the data type.

[0099] After the second verification passes, the oil and gas sector data in the oil and gas sector event data body is verified based on the data exchange model type.

[0100] Specifically, the first verification is to determine whether the oil and gas event data body corresponds correctly to the oil and gas sector.

[0101] The second verification step involves checking the data exchange model type and data type of oil and gas sector data. The third verification step involves verifying the oil and gas sector data within the event data body based on the data exchange model type. For example, seismic field data is verified using the seismic field exchange model, and well logging curves are verified using the well logging curve exchange model. Furthermore, pattern verification is performed upon data reception; if the patterns do not match, the data can be rejected, thus ensuring data consistency. Synchronization markers are included in binary format data, allowing the location and identification of corrupted data blocks during data transmission, thereby ensuring data integrity.

[0102] Step 306: After the verification is passed, according to the data discovery rules of each oil and gas work area, send the oil and gas field data that conforms to the data discovery rules in the oil and gas field event data body to the corresponding oil and gas work area.

[0103] Data discovery rules can be configured based on the scope of master data, change type (such as addition, modification, deletion, etc.), or other business logic. Specifically, matching can be performed according to pre-defined data discovery rules. If the data discovery rules are met, a corresponding data notification action will be triggered. For example, a workspace studies a block and needs well logging data within the block. The data discovery rules define the inclusion relationship between the well spatial geographic location and the block spatial geographic location. If the data discovery rules are met, a notification is sent to the workspace indicating a new interpretation conclusion. When the well logging DMS generates a new interpretation conclusion, a notification is sent after the data interpretation is completed, indicating that the data discovery rules defined for that workspace are met, and a notification is sent to the workspace indicating a new interpretation conclusion. Data discovery rules are flexibly configurable. In addition to rules related to spatial geographic location information, rule definitions can also be set for dimensions such as time range, business stage, and well depth.

[0104] In this embodiment of the invention, the oil and gas data service control system updates the data index based on data discovery rules. For example, if multiple well logging interpretation conclusions are adjusted on a certain day, according to the data discovery rules, only the interpretation results of the last modification time are indexed.

[0105] This invention also proposes a data change notification device for the oil and gas sector, such as... Figure 4 This is a schematic diagram of the structure of the oil and gas sector data change notification device in an embodiment of the present invention. The device is applied to various oil and gas sector data centers, and each oil and gas sector data center communicates with the oil and gas sector data service control system. The device includes:

[0106] The event change type determination module 401 is used to determine the current event change type when an oil and gas data change event occurs.

[0107] The oil and gas sector event data body production module 402 is used to generate an oil and gas sector event data body when the event change type is a notification type. The oil and gas sector event data body includes oil and gas sector data based on changes in data exchange model type.

[0110] The active push module 405 is used to send the data change request to the oil and gas field data service control system, so that after the oil and gas field data service control system verifies the summary information and the identity token of the oil and gas field data center in the data change request, it verifies the changed oil and gas field data body in the data change request according to the data exchange model type, and after the verification is passed, it sends the oil and gas field data that meets the data discovery rules to the corresponding oil and gas work area.

[0111] In one embodiment, the active push module 405 is further configured to:

[0112] Before sending the data change request to the oil and gas field data service control system, if the size of the data change request exceeds a first preset data size, the data change request is converted into a binary data serialization format.

[0113] When the size of a data change request in binary data serialization format exceeds the second preset data size, a lossless compression algorithm is used to compress the data change request in binary data serialization format.

[0114] The compressed data change requests are stored in a memory-based queue;

[0115] A multi-threaded asynchronous program is used to send compressed data change requests from a memory-based queue to the oil and gas data service control system.

[0116] In one embodiment, the active push module 405 is further configured to:

[0117] The multi-threaded asynchronous program actively invokes the data change service of the oil and gas field data service control system, and pushes compressed data change requests from a memory-based queue to the oil and gas field data service control system.

[0121] Based on the version change information of the retrieved data, obtain incremental data;

[0122] The generated data change request is sent to the oil and gas field data service control system through the passive refresh interface of the oil and gas field data service control system.

[0123] This invention also proposes another data change notification device for the oil and gas sector, such as...

The data change request includes an oil and gas field event data body, summary information, and an identity token of the oil and gas field data center. The summary information is generated by hashing the key fields of the oil and gas field event data body. The oil and gas field event data body includes the changed oil and gas field data based on the data exchange model type.

[0125] Verification module 502 is used to verify the identity token of the oil and gas field data center;

[0138] In summary, in the method, apparatus, and system proposed in the embodiments of this invention, when an oil and gas data change event occurs, the current event change type is determined; when the event change type is a notification-required type, an oil and gas event data body is generated, which includes changed oil and gas data based on a data exchange model type; a summary information is generated from the key fields of the oil and gas event data body using a hash function; a data change request is generated based on the oil and gas event data body, the summary information, and the identity token of the oil and gas data center; the data change request is sent to the oil and gas data service control system, so that after the oil and gas data service control system verifies the summary information and the identity token of the oil and gas data center in the data change request, it verifies the changed oil and gas data body in the data change request according to the data exchange model type, and after the verification is successful, the oil and gas data that conforms to the data discovery rules is sent to the corresponding oil and gas work area. In the aforementioned process, data changes based on an event mechanism require determining the type of event change. Data processing only occurs when a notification type is required. To improve data push efficiency and security, oil and gas sector data is encapsulated into an oil and gas sector event data body, and this data is based on a data exchange model type. To further enhance data transmission security, a dual protection approach using summary information and identity tokens is employed. After receiving a data change request, the oil and gas sector data service control system verifies it. Upon successful verification, it sends oil and gas sector data conforming to the data discovery rules to the corresponding oil and gas work area, achieving targeted push notifications for specific oilfield work areas. This invention not only enables timely acquisition of the latest data changes but also allows for rapid indexing of new data, facilitating real-time adjustments to work by users in oil and gas work areas based on the latest data. Users can more quickly discover changes in data content, thereby improving data processing efficiency.
