Abstract
In recent years, some scholars use petroleum system as an oil geological unit of basin, so that they have put forward a suggestion of treating it as a target at some expl oration stage. How to use the concept directly relates to the result of its appl ication. Mechanically applying petroleum system would make you being at a loss a s to what to do or restricted on continually extending the exploration area in p ractical exploration. Proceeding from practice, it is appropriate that petroleum system is defined as a comprehensive analysis method. The exploration of a basi n is a progress step by step, and the geologi cal knowledge of the basin is corrected and deepened again and again in the prog ress. In the light of the original meaning, petroleum exploration is not to prov e some objective reality but to press on towards the objective facts for the pur pose of profits in the course of working. A petroleum system drawn in an area is only a view of some geologists at some exploration stage. Along with the deepen ing of exploration, the view must be revised continually. From this point, petro leum system is a progress of cognition accompanying petroleum exploration all al ong. Petroleum system is a comprehensive analysis method of excellent logic. The main peculiarity of it is that it forms a integrated effective analysis procedu re by synthesizing various analysis methods. Through comprehensive analysis meth od, petroleum system links sources with reservoirs (traps) in time and space, co njectures favorable areas and guides exploring activities. Along with the deepen ing of oil exploration of a basin and the accumulating of data continually,the corresponding relationships between sources and reservoirs(traps)become manifold more and more,and the depictions of petroleum systems become much more clear.

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.
