What data for this category looks like
Oilfield engineering service ledger data derives from on-site construction original records, including construction logs for drilling, cementing, fracturing and other operations, equipment operating parameters, material requisition lists, and acceptance documents. Data updates per individual construction project or daily construction batch. Each ledger includes fixed fields: operation date, well ID, operation type, pressure, displacement, temperature, material usage, operating personnel, and acceptance results. Units include MPa, m³/min, tons, degrees Celsius and other professional engineering units.
Constraints on model access and configuration
Professional fields and units of oilfield ledgers require the model to accurately identify and match original data, to avoid unit conversion or field extraction errors. The content length of a single ledger can reach thousands of characters. Multi-batch summaries require accommodating large volumes of text, which imposes clear context length requirements on the model. Data updates daily per construction batch, so the model must quickly load the latest batch of ledger data when called. It must also adapt to differences in field combinations across different operation types, to avoid adaptation issues with fixed tool calls.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Adapts to the summary length of single or multiple oilfield ledgers, avoids context overflow |
maxTokens | 4000–6000 tokens | Balances token consumption for professional field processing and output length for report generation |
temperature | 0.1–0.3 | Reduces randomness in model generation, ensures matching accuracy between ledger data and fields |
toolChoice | auto | Allows the model to independently determine whether to call document parsing tools, adapts to differences in ledger field combinations across different operation types |
AIPROXY_API_ENDPOINT | Proxy address specified per local deployment environment | Adapts to the local API access path for FastGPT v4.17.0 |
AIPROXY_API_TOKEN | Exclusive security token generated during deployment | Ensures legitimacy of access permissions for model API calls |
Three common configuration mistakes
- Phenomenon: The model returns a context overflow error, or output content is truncated. Cause: The
maxContextparameter is not configured appropriately for oilfield ledgers, resulting in exceeding the model's supported context length. - Phenomenon: Tool calls fail, returning unrecognized operation fields or parameter errors. Cause:
toolChoiceis set to a fixed tool type, which cannot adapt to differences in ledger field combinations across different operation types such as drilling and fracturing. - Phenomenon: Unit errors appear in the generated report, such as converting MPa to bar. Cause: The
temperaturevalue is set too high, causing the model to generate non-standard unit content that deviates from the original data.
How to confirm the configuration is correct
- Upload a complete oilfield construction ledger document, verify that the model can accurately extract preset core fields.
- Trigger a summary task for multiple ledgers of different operation types, check that the model can complete content integration without errors.
- Initiate a test call, confirm that the model can independently select appropriate document parsing tools to process ledger data.
- Verify the API proxy address and token configuration, check that model call requests can be initiated and completed normally.
