Abstract

fetched live from OpenAlex

Abstract In view of the character of heavy oil reservoir in Shengli oilfield under thermal production, the analysis that heterogeneity of oil reservoir, viscosity of crude oil, oil thickness, recovery efficiency of recoverable reserves and distance to the oil-water boundary affect the effectiveness of nitrogen foam profile control was made by reservoir numerical simulation and statistical interpretation of production effect of some wells which had being implemented nitrogen foam profile control. On that basis, a prediction model of nitrogen foam profile control technology was founded by means of the fuzzy comprehensive evaluation, and the reservoir conditions which adapt to nitrogen foam profile are presented. The results The adaptive research of nitrogen foam profile control in steam stimulation reservoir can enhance the pertinence and effectiveness of nitrogen foam profile control technology and improve the efficiency of multi-round steam stimulation in heavy oil reservoir.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
