What the data for this category looks like
Policy and regulatory basis data for oilfield engineering services primarily comes from oil and gas industry specifications released by the National Energy Administration, internal engineering service rules of central oil enterprises under the State-owned Assets Supervision and Administration Commission, and SY/T series industry standard documents. The data update rhythm follows national standard revisions and internal enterprise workflow adjustments.
Most documents use a chapter-based structure, and include fields such as document number, issuing body, effective date, applicable operation links (such as drilling, fracturing, environmental protection and operation), clause content, and more. Some documents include professional parameter units, such as megapascals for pressure, days for operation duration, and cubic meters for consumable usage.
What constraints do these characteristics impose on the knowledge base retrieval and recall link
The characteristics of oilfield engineering service policy and regulatory basis data impose multiple constraints on the retrieval and recall link.
Data sources are scattered, including public national standards and internal enterprise rules. Permission isolation rules must be configured to prevent unauthorized cross-level, cross-subject retrieval. Documents use a chapter-based structure and are tied to operation links. When splitting document chunks, the association between clauses and operation scenarios must be retained to avoid semantic breakage after splitting. Some documents include professional unit parameters. Retrieval must match parameter unit consistency to prevent valid content from being filtered due to unit mismatches. The update rhythm has no fixed cycle. Regular synchronization tasks must be configured to ensure retrieved content stays synchronized with the latest policies and operation rules.
How to set the configurations
| Config Item | Recommended Value Range | Rationale for This Value |
|---|---|---|
similarity | 0.75–0.85 | Oilfield policy documents have high professionalism, requiring filtering of low-correlation content. This range balances recall precision and coverage |
limit | Top 8–12 entries | Individual policy documents have long content. Too many recalled entries will exceed the context carrying capacity. This range retains core clauses |
searchMode | Semantic retrieval | Policy documents are mostly long texts with dense professional terms. Semantic retrieval can match deep semantic associations |
usingReRank | Enabled, take top 3–5 entries | Reranking filters results that are semantically similar but do not match the operation scenario. The top 3–5 entries focus on core policy clauses |
datasetSearchUsingExtensionQuery | Enabled | Oilfield policy questions often contain professional abbreviations or specific operation terms. Extended queries supplement synonym matching |
collectionIds | Bind corresponding knowledge base collections by operation link | Distinguish policy collections for different operation scenarios such as drilling, fracturing, environmental protection to accurately locate data sources |

Three Common Misconfigurations
- Phenomenon: After configuring
usingReRank, the task reports an error indicating the model cannot run. Cause: The reranking model's operating parameters are not configured correctly, or the allocated memory is insufficient to load the model file. - Phenomenon: The number of results returned by knowledge base retrieval is insufficient to cover all policy basis required by the business. Cause: The
similaritythreshold is set too high, or the value range oflimitis too narrow, filtering some eligible content. - Phenomenon: After the workflow calls knowledge base search, the returned content does not match the policy of the specified operation link. Cause: The
collectionIdscorresponding to the operation link are not bound, resulting in the retrieval scope covering irrelevant policy documents.
How to Confirm the Configuration is Correct
- Manually enter a policy question corresponding to the operation link, check whether the similarity score of the returned results matches the preset range.
- View the number of retrieval returned results, confirm that the quantity matches the set
limit. - Test the reranking function, check whether the sorting of the returned results is more aligned with business scenario requirements.
- Check the bound
collectionIds, confirm that only the policy knowledge base collections of the current operation link are included.
