What the data looks like
Data sources for oilfield services engineering research reports include domestic oil and gas exploration and development industry research institutions, internal technical archives of oilfield services enterprises, and public oil and gas engineering technical reports. Update cadence falls into three categories: major project research reports are updated immediately alongside construction milestones, regular industry dynamics reports are updated weekly, and emergency technical adjustment reports are released on demand. Each individual document includes fields such as operating area coordinates, well identification, construction cycle, equipment model, consumable usage, cost breakdown, risk warnings, and more. Units include meters, cubic meters, yuan per barrel, hours, and others. Some documents include attachments of engineering drawings and data tables.
Constraints Imposed on HTTP Interfaces and External Systems
The multi-source, multi-format, and multi-field characteristics of oilfield services engineering research reports impose multiple constraints on HTTP interface and external system integration. Multi-source data requires interfaces to support connection to data source interfaces with varying permission levels, and requires authentication parameter configuration. The mixed semi-structured and structured document structure requires interfaces to support both structured parameter extraction and unstructured text parsing. Diverse engineering parameter units require interfaces to support custom field mapping and unit conversion rules. Non-fixed update frequency based on project milestones requires interfaces to support flexible configuration of incremental synchronization and trigger-based pulling. Long documents with large attachments require interfaces to relax request timeout and file size limits.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Oilfield services engineering research reports often contain long technical paragraphs and engineering drawing parsing, requiring relaxed timeout limits |
UPLOAD_FILE_MAX_SIZE | 2000 MB | A complete single project research report may include multiple engineering drawings and data tables, requiring adaptation to large file upload requirements |
Recall count | Top 10–15 results | Oilfield services engineering research reports have high professional parameter relevance, requiring sufficient retrieved segments to cover complete technical logic |
Similarity threshold | 0.75–0.85 | High precision matching is required for engineering parameters, requiring a high threshold to filter low-relevance non-professional results |
Incremental Sync Trigger Mode | Event-driven | Major project research reports are updated with construction milestones; fixed periodic pulling may miss or duplicate data, requiring connection to the data source's event notification interface |
Field mapping rule | Custom mapping | Oilfield services include exclusive parameter names and units, requiring mapping of external data source fields to the platform's unified retrieval fields |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis; it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Calling the data source interface returns a 403 Forbidden error, and logs show insufficient permissions. Cause: Authentication parameters for the corresponding data source are not configured, or the permission scope does not cover the exclusive data directory of oilfield services engineering research reports.
- Phenomenon: Executing the upgrade command returns a 404 error for POST /api/admin/initv4818. Cause: The FastGPT service was not stopped in advance, or the current deployed version does not match the target version of the upgrade script.
- Phenomenon: Calling the knowledge base interface does not return session context results associated with historical construction data. Cause: The session ID parameter was not included in the interface request, or session persistence configuration was not enabled, making it impossible to retain the retrieval context of oilfield services engineering research reports.
How to Verify Successful Configuration
- Call the configured data source docking interface, and confirm that structured data including operating area, well ID, and consumable usage is returned. Verify that field mapping and unit conversion take effect.
- Upload a single research report attachment not exceeding 2000 MB, and confirm that the parsing task completes within 600 seconds with no timeout errors.
- Trigger the incremental synchronization interface, and confirm that only new research report data from the past 7 days is updated, with no full repeated pulling.
- Set the similarity threshold to 0.8, retrieve construction parameters for a specific well ID, and confirm that the matching degree of retrieved results meets expectations.
