What data for this category looks like
Oilfield services engineering research reports come from three main sources: public reports from industry associations, internal operation statistics of oil service companies, and special analysis documents from third-party professional consulting institutions. Updates follow monthly and quarterly standard cycles, with temporary supplementary updates for major industry events such as oil price fluctuations and the launch of new drilling technologies. Document structures typically include cover notes, core operation data tables, industry trend interpretations, policy impact analyses, and typical project cases. Most fields are professional metrics, such as total number of drilling rigs, footage per well, operation days, and unit operation cost. Corresponding units are units, meters, days, and yuan/meter. Some documents contain multi-page long tables for aggregated data.
What constraints do these characteristics impose on deployment and upgrade
The long tables, professional metric fields, and non-fixed update cycles of oilfield services engineering research reports create multiple constraints for deployment and upgrade workflows. Long tables and multi-chapter content increase file parsing time, requiring adjustments to parsing timeout parameters. Precise matching of professional fields requires knowledge base index configurations to adapt to technical terminology, avoiding field mapping errors. Non-fixed update frequencies require incremental synchronization configurations during upgrades, eliminating the need for full re-import of historical data. For intranet deployment scenarios, authenticated proxy configuration support is required to access external industry data sources.
How to configure settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Oilfield services engineering research reports often contain multi-page long tables and multi-chapter content, with significantly higher parsing time than general documents |
UPLOAD_FILE_MAX_SIZE | 2000 MB | A single annual summary research report may exceed 1000 MB, so sufficient upload space must be reserved |
maxContext | 8000–12000 characters | The professional content of a single chapter of the research report is lengthy, so sufficient context must be covered to support accurate question answering |
RECALL_NUMBER | Top 8 entries | Professional data from oilfield services engineering research reports is scattered across multiple chapters, so a sufficient number of relevant fragments must be recalled |
Similarity Threshold | 0.75–0.85 | Low-correlation general industry documents must be filtered out, retaining only professionally matched data fragments |
PROXY_USERNAME/PROXY_PASSWORD | Fill in according to the actual configuration of the intranet proxy | Intranet deployments require authenticated proxies to access external research report data sources |
The parameter values provided on this page are common starting points for configuration. The actual values are affected by material format, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Symptom: External research report data source fails to load during intranet deployment, with 407 proxy authentication error in logs. Cause: Only proxy IP and port are configured, but
PROXY_USERNAMEandPROXY_PASSWORDare not filled in, so access to external data sources via authenticated proxy fails. - Symptom: Saved large model configuration becomes invalid after upgrading from 4.8.14 to 4.8.15, and unbound models are called during chat. Cause: The storage fields for model configuration are adjusted after the version upgrade, and the bound parameters in the application are not synchronized and updated.
- Symptom: Retrieval results are empty after parsing oilfield services engineering research reports in a Docker-deployed instance. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, so long table parsing is not completed before entering the indexing phase, resulting in partial data not being loaded.
How to verify correct configuration
- Upload a single quarterly oilfield services engineering research report, confirm whether the parsing progress completes within the time set by
PARSE_FILE_TIMEOUT_SECONDS. - Submit a query with professional terminology, such as "Current total number of domestic drilling rigs", check if retrieval results include matching data from the research report.
- Confirm that
PROXY_USERNAMEandPROXY_PASSWORDmatch intranet proxy rules, then attempt to access the external research report data source interface. - After upgrading the version, open the application settings page to view model binding configurations, confirm the displayed model identifier matches expected values.
