The Characteristics of the Dominant Flow Channel Using Ma20 Block in the Liaohe Oilfield as an Example
Bibliographic record
Abstract
The existence of the dominant flow channel caused the oil field recovery efficiency low, the rising cost of production and the development benefit drop, which brought great pressure to oilfield development, so the study of the characteristics of the dominant flow channel is increasingly urgent. According to the geologic features and the production process of long-term water injection development in the Ma20 block of the Liaohe oilfield, reservoir heterogeneity is the root cause of forming the dominant flow channel. The characteristics of the dominant flow channel in the process of water injection were analyzed. By analyzing the performance characteristics of the dominant flow channel in the dynamic production data, electrical, static and so forth, the dominant flow channel was determined to guide water injection development of oilfield and provide the basis for the research of other dominant flow channel of high water-cut stage reservoir. Key words: The dominant flow channel; Development benefit; Geologic features; Heterogeneity; Development of water injection

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
