What the data for this category looks like
The oilfield service engineering investment research knowledge base for financial industry investment research scenarios draws data primarily from on-site operation systems, real-time data collected by downhole sensors, public reports from industry associations, and completion documents delivered by third-party exploration service providers. The data update cycles vary significantly: real-time on-site operation parameters are uploaded per second, single-well drilling logs are generated incrementally as work progresses, project completion reports are submitted within weeks after work ends, and industry public reports are updated monthly. Document structures include well location numbers, operation dates, operation phases, measured parameters, on-site anomaly records, and other fields. Some structured fields have dedicated units: for example, depth is measured in meters, pump pressure in megapascals, and permeability in millidarcys. Unstructured content mostly consists of on-site operation descriptions and analysis conclusions.
Constraints imposed on deployment and upgrade by these characteristics
The data characteristics of oilfield service engineering impose multiple constraints on the deployment and upgrade process. The per-second real-time data upload requirement requires configuring a streaming data access buffer during deployment, and the data flow must not be interrupted during upgrades. The size of individual documents varies widely, with some large drilling logs reaching several GB, so elastic parsing resources must be deployed, and the single-file upload limit cannot be restricted during upgrades. Dedicated fields and units require pre-configured field mapping rules during deployment, and existing mapping relationships must not be broken when upgrading the knowledge base. Some data comes from internal network sensors, so internal network offline deployment must be supported, and the upgrade process must not rely on public network dependency downloads. Knowledge base content divided by project requires configuring version-isolated storage paths during deployment to avoid mixing documents from different projects.
Configuration settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000–2000 MB | Adapts to the maximum size requirement of single-well drilling logs for oilfield service engineering, with reasonable buffer space reserved |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Meets the time consumption requirement for parsing large drilling logs, avoids mid-process timeout interruptions |
RECALL_TOP_N | Top 8–12 entries | Covers multi-dimensional oilfield service engineering operation parameters required for financial investment research, balances recall accuracy and response speed |
SIMILARITY_THRESHOLD | 0.72–0.85 | Distinguishes parameter characteristics of similar operation phases, avoids invalid recall interfering with investment research judgments |
DOCKER_VOLUME_PATH | /data/fastgpt/oilfield | Mounts a high-performance disk separately to store oilfield service engineering documents, prevents system disk exhaustion from affecting overall service |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common misconfigurations
- Symptom: A
403 Forbiddenerror occurs during internal network deployment, and initialization cannot be completed. Cause: The internal network image repository address is not configured, and pulling the default public network image source results in insufficient permissions. - Symptom: All knowledge base configurations and docking parameters are lost after server restart. Cause: The container data volume is not mounted to a persistent storage directory, and temporarily stored configurations are cleared when the container is destroyed.
- Symptom: Some drilling logs fail to parse after upgrade, returning a
504 Gateway Timeouterror. Cause: An outdated docker-compose configuration is used, and the timeout parameter settings of the new parsing engine are not adapted.
How to verify correct configuration
- Upload the largest single-volume drilling log document, verify that the upload progress bar completes without errors, and confirm that the
UPLOAD_FILE_MAX_SIZEconfiguration meets actual requirements. - Restart the server and containers, check that knowledge base configurations and docking parameters are not lost, and confirm that the persistent storage mount is correct.
- Trigger a batch parsing job, verify that parsing time consumption meets expectations, and confirm that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration is reasonable. - Retrieve operation parameters for a specific well number, verify that the recall results include corresponding fields and units, and confirm that the field mapping rules are active.
