Abstract
作为综合性时延地震方案的一个主要内容，对Pan Canadian的Weyburn 油田薄层状裂缝碳酸盐岩油藏的大规模CO2注气进行监测，于2000年8月在注气前，成功地采集到了水平井井间地震测量的原始数据。该项目的目标是要推广可能追踪作为时间函数的CO2含量详细变化的技术以及证实地面地震数据（3分量和9分量三维）和三维VSP的监测效力（在相同的时间里做这两项工作）。这实现这一目标，用成本效果（分析）法和在一个产量限定的时窗内，结合作用压电震源挠性管和48级压敏检波器串的创新技术，在两口平行水平井进行了作业。所记录的资料展示了以很多有用波型组成的波场。处理结果表明，用压缩波（纵波）、剪切波（横波）和管道波导波的层析成像，对监测注CO2气的效应有较好效果。我们相信，这次在Weyburn作业的成功，向人们展现出井间地震技术的广泛应用前景。

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.
