Abstract
The oil displacement properties of an environment friendly surfactant named YCH-601 and its combination system were studied.Biological toxicity evaluation test showed that YCH-601 had no toxicity,no skin irritation and no allergic reaction.The laboratory experiment results showed that YCH-601 had a better emulsifying capability to crude oil than that of usual surfactants used in oilfield.And the absorption of YCH-601 on the surface of sandstones was lower with a sustained dynamic absorption of 0.123 mg/g sand.Compared with other surfactants,surface tension reducing effect of YCH-601 was the best with the lowest working concentration,whose lowest surface tension was of 26.7 mN/m.Its combination systems of AON and ASN,which could reduce surface tension effectively,provided high resistance to Na+ which concentration was of 20 g/L and 50 g/L respectively,and that to Ca2+ was of 1500 mg/L and 4000 mg/L respectively.Moreover,after treated with high temperature of 150℃,both systems could still reduce the oil-water interfacial tension to the order of 10-3 mN/m.Both YCH-601 and its combination systems could enhance the oil recovery better that other surfactants,and the enhanced oil recovery was as high as 22.5%.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
