What this category of data looks like
Oilfield engineering services declaration materials and file data primarily comes from project approval applications, construction process logs, completion acceptance reports, and qualification certification documents. Update frequency is adjusted in stages alongside project progression. Full declaration materials are submitted during the approval phase. On-site records are updated synchronously during the construction phase. Files are finalized for archiving after acceptance is completed. Most documents combine structured forms and unstructured text. Documents include fields such as project number, construction unit, qualification level, engineering quantity, acceptance node, and others. Units of measurement include cubic meters, man-hours, tons, and others. File formats cover PDF, Excel, and scanned document formats.
What constraints these characteristics impose on the citation sources and traceability link
Oilfield engineering services declaration materials and files have mixed structured and unstructured text features. Traceability must accurately match both form fields and on-site record paragraphs.
Declaration materials and files are updated in stages across the project cycle. Traceability links must associate document versions across the full project timeline. This prevents citing outdated construction or qualification data.
Multiple file formats are used for these materials. Search engines must support content splitting and indexing across different formats.
Declaration materials and files have a strong correlation. Traceability results must associate different document entries under the same project. This ensures review basis is complete.
How to configure
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
quoteMaxToken | 1500–2000 token | Preserve complete context of declaration materials and files to support field traceability |
responseData | Enabled | Output metadata and original text fragments of associated documents to facilitate review and traceability |
detail | Full | Display original format and field information of cited content, matching engineering document review requirements |
| Chunk Length | 800–1200 characters | Adapt to the paragraph and field length of oilfield engineering documents. Avoid splitting form fields across chunks |
| Similarity Threshold | 0.75–0.85 | Filter poorly matched unrelated engineering documents. Ensure cited content aligns with review needs |
| Single Search Limit | Top 6 entries | Cover multiple files, declaration materials, and qualification documents under the same project |
Three common errors
- Phenomenon: Simple workspace knowledge base applications only return 1 cited document per response. They cannot associate multiple files under the same project. Cause: The single search limit is set too low. Cross-document association retrieval logic is not enabled.
- Phenomenon: Some review scenarios cannot display original text fragments of cited content. Only abstract information is shown. Cause:
detailis set to concise mode. TheresponseDataswitch is not enabled. - Phenomenon: Reviewers find cited engineering quantity data lacks corresponding units of measurement. Field information is incomplete. Cause: Chunk length configuration is unreasonable. Document splitting truncates field paragraphs that include measurement units.
How to confirm the configuration is correct
Upload a test set of oilfield engineering declaration materials and files. Initiate a review query. Verify returned cited content includes core fields such as project number and engineering quantity.
Check the citation module display format. Confirm original text fragments and document metadata are shown, matching preset detailed display requirements.
Adjust the single search limit configuration. Initiate multiple queries. Confirm the number of returned cited documents changes with the configuration adjustment.
Test uploading files in different formats. Confirm search results cover engineering documents including PDF and Excel types.
