Abstract
平稳的启动对SAGD的成功操作是至关重要的。对SAGD井对的启动或者说循环阶段通过数值模拟进行了分析。采用耦合油藏/井筒模型，并用井的现场数据进行了历史拟合，数据由Petro-Canada的MacKay River开发区块大量仪器测得。历史拟合模型后来用于（对井对循环有影响的）某些参数进行敏感性研究。首先，对两种典型的完井方式，蒸汽到达趾端的时间进行了研究，这两种方法是Petro-Canada在MacKay River所用的两种典型井筒完井方法。对这两种完井方式进行了大量的流动速度检验，以弄清蒸汽注入速度如何影响蒸汽到达趾端时间。其次，研究了循环压力和注入/生产井压力梯度。在注入/生产井间采用了不同的压力梯度，以检验其对循环持续时间和蒸汽锥进形成的影响。最后，对注入井和生产井间的距离进行了研究，目的是研究注入/生产井的垂向距离对转换时间的影响。

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.
