摘要Hydrogen from stratigraphic water may compensate for H-depleted kerogen, and it may produce more shale gas resources. The contribution of water-derived hydrogen to methane was calculated via deuterium atom transfer from labelled water (enriched H-2) to the methane generated from the pyrolysis experiments of high-maturity kerogen. The results showed that methane had enriched 2H up to 8040-9509 parts per thousand with labelled water addition. According to deuterium atom transfer calculations, we found that water contributes 12.91-15.15 % hydrogen to methane, with the contribution proportion increasing with increasing thermal maturity. These results suggest that in high-over matured shale rocks, water might contribute to shale gas reserves for late methane generation from the residual hydrogen-exhausted kerogen.
