Abstract
Large amount of coalbed methane(CBM)is produced in the US,Canada,and Australia.From the development of CBM industry at home and abroad,we can see that 1)the development of CBM industry is a long and rough road;2)favorable policies will help to promote the development of CBM industry;3)rapid development of CBM industry needs the involvement of big oil companies.SINOPEC has more than 8 trillion cubic meters of CBM resources.Analysis of geology and block screening reveal that the Heshun block in the Qinshui basin,the southern margin and the northern part of Ordos Basin and the eastern Yunnan-western Guizhou region are the key areas for developing CBM in the near term.We suggest Sinopec see CBM as important as conventional oil/gas and adopt positive investment strategies.First,get access to as many as CBM resources both at home and abroad through block leasing,acquisition and cooperation with other companies.Second,treat existing blocks differently.For the Yanchuannan,Heshun and Zhijin blocks which have already found CBM,pilot production and further appraisal should be conducted in order to realize commercial production.For blocks in the northern part and the southern margin of Ordos Basin and in the eastern Yunnan-western Guizhou region,exploration should be deepened in order to make a breakthrough.For blocks in southern North China Basin and Northwest China,exploratory work should be carried out in order to appraise their CBM potential.Third,intensify investment in RD and build an integrated team of management,production and scientific research to ensure the fast and healthy development of SINOPEC's CBM exploration and production.

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.
