What the Data for This Category Looks Like
Data sources for oilfield service engineering intelligent due diligence reports include drilling construction records, fracturing operation ledgers, equipment operation and maintenance logs, industry compliance qualification documents, and third-party inspection reports. Data is updated in real time per operation node during a single project’s construction cycle, and synchronized quarterly after project completion and archiving. Document structure includes four core modules: basic project information, detailed construction parameters, equipment operation data, and compliance review results. Fields include drilling depth (unit: meters), fracturing sand dosage (unit: tons), equipment number, qualification validity period, and others. A complete single document has a relatively long length.
Constraints Imposed on HTTP Interfaces and External Systems
The data characteristics of oilfield service engineering due diligence reports impose multiple constraints on HTTP interface and external system integration. Multi-source real-time updated data requires interfaces to support incremental pull or Webhook push, to avoid excessive bandwidth and processing resource consumption from full synchronization. The long, multi-field document structure requires interfaces to support specifying recalled fields, reducing invalid data transmission. Fields with specific units require interface parameter verification logic to match unit formats, intercepting non-standard input data. External system integration must be compatible with common operation data formats used in oilfield service engineering, while strengthening interface authentication logic to protect commercially sensitive construction and compliance data.
Configuration Settings
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
API_REQUEST_TIMEOUT | 300–600 seconds | A single oilfield service engineering due diligence report has a large data volume, so the interface must reserve sufficient time for parsing and response |
maxContext | 8000–12000 characters | Must accommodate context information from multiple construction records and equipment logs, avoiding truncation of critical due diligence data |
recall_count | Top 10–15 entries | Oilfield service engineering data has numerous and detailed fields, so a sufficient number of associated documents must be recalled to cover all dimensions of information required for due diligence |
similarity_threshold | 0.75–0.85 | Distinguish professional construction parameters from irrelevant background information, accurately matching core due diligence data related to compliance and construction |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | A single oilfield service engineering due diligence report has a relatively long document length, requiring a longer timeout for file parsing |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Accommodate complete construction videos, equipment ledgers and other attached due diligence data, avoiding upload failures |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Specific issues require case-by-case analysis, and it is recommended to test against samples before finalizing.
Three Common Misconfigurations
- A
400 Bad Requesterror is returned when calling the interface, with a prompt indicating that thechatIdparameter is missing or formatted incorrectly. The symptom is that multi-turn conversations cannot associate historical due diligence data. The cause is failure to consistently pass thechatIdparameter, leading to interruption of the conversation context and inability to associate construction data from different operation nodes. - A
413 Request Entity Too Largestatus code is returned when uploading a due diligence report, with the symptom of failed file upload. The cause is failure to adjust theUPLOAD_FILE_MAX_SIZEconfiguration. Oilfield service engineering due diligence reports contain a large number of construction videos, log attachments and other content, exceeding the default upload size limit. - The due diligence results returned by the interface lack compliance qualification related content, with the symptom of incomplete fields in the recall results. The cause is that the similarity threshold is set too high, filtering low-similarity but critical due diligence data such as qualification documents, or the recall count is set too low to cover relevant documents.
How to Verify Proper Configuration
- Initiate an upload request for a single complete oilfield service engineering due diligence report, check that the interface returns a
200 OKstatus code, confirming that theUPLOAD_FILE_MAX_SIZEconfiguration is effective. - Initiate two associated conversation requests with a consistently passed
chatIdparameter, check that the second round of returned results associates the construction stage data mentioned in the first round, confirming that context transmission is working properly. - Initiate a knowledge base recall request, check that the returned results include professional fields with units such as drilling depth and fracturing sand dosage, confirming that field parsing and recall configurations are effective.
- Simulate a large-volume document request, set the request timeout to 80% of
API_REQUEST_TIMEOUT, check that the interface returns results within the set time, confirming that the timeout configuration is effective.
