What the data for this category looks like
Oilfield service engineering investment research data mainly comes from drilling logs, fracturing construction reports, reservoir evaluation documents, industry technical specifications, and internal enterprise operation records from oil and gas enterprise operation sites covered by financial institutions. Data updates occur in real time as construction projects progress. Industry trend reports are updated monthly, and technology iteration documents are released quarterly. Documents include structured fields and unstructured content. Structured fields include well ID, operation date, formation permeability, construction pressure, and more. Units mostly use professional measurement standards such as MPa, mD, meters, cubic meters. Unstructured content covers on-site fault analysis, construction review records, and similar materials.
What constraints do these characteristics impose on multi-turn dialogue and prompt engineering?
The mixed structure of oilfield service engineering investment research data requires multi-turn dialogue to distinguish between structured parameter queries and unstructured technical questions. Key identifiers such as well ID, block, and enterprise name specified in the current session must be retained during context splicing to avoid parameter confusion across projects and enterprises. Frequently updated operation data requires prompts to include real-time data verification logic. This prevents returning expired historical operation records that impact investment research conclusions. Multiple types of professional units require prompts to enforce unified unit conversion rules. This ensures query units match knowledge base data and avoids errors in investment research analysis. Long documents require multi-turn dialogue to filter irrelevant context. Only operation parameters and historical follow-up content related to the current session are retained.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 tokens | Single-project operation data for oilfield service engineering investment research has large volume. Sufficient context must be retained to support multi-turn parameter queries and comparative analysis for investment research personnel |
Number of Retrieved Entries | Top 6 entries | Balances retrieval coverage for structured operation data and unstructured technical documents. Avoids redundant single-entry retrieval that impacts investment research judgments |
similarityThreshold | 0.72–0.80 | Matches semantic differences in oilfield service engineering professional terms. Filters low-relevance general industry documents to improve accuracy of investment research queries |
maxHistoryTurns | Previous 4 dialogue turns | Limits historical context length. Avoids interference from irrelevant operation records in long sessions on current investment research queries |
prompt_template | Concatenated in the format of "operation scenario + parameter unit + historical context" | Enforces unified unit conversion, clarifies the operation scope and enterprise subject of the current session, and adapts to investment research analysis needs |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Reserves sufficient parsing time when processing long-cycle operation log documents. Prevents parsing failure for large investment research documents |
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
- Symptom: Responses from multiple
<ai dialogue>nodes in a workflow all appear in a single session. Cause: ThemaxHistoryTurnsparameter is not configured to limit historical rounds, resulting in context from all historical nodes being retained. - Symptom: Inconsistent units in multi-turn dialogue lead to empty query results. Cause: The prompt does not enforce conversion to oilfield service engineering standard units, and no unit verification rule is added during context splicing.
- Symptom: User historical dialogue records cannot be saved in login-free scenarios. Cause: Temporary session identifiers are not bound to user browser cache, and the expiration time parameter for session persistence is not configured.
How to Confirm Successful Configuration
- Initiate two consecutive queries. First, query fracturing pressure data for a specified well ID. Second, follow up with parameters for another well in the same block. Confirm that returned results only include well ID and block information specified in the current session.
- Enter a query containing non-standard units. Confirm that returned results are automatically converted to oilfield service engineering standard units and match corresponding operation data.
- Trigger multiple
<ai dialogue>nodes in a workflow. Confirm that only the latest reply from the current workflow execution is displayed in the session, with no redundant content from historical nodes. - After connecting to the user system, initiate the same query using different accounts. Confirm that each account can only view its own historical dialogue records.
