摘　　要：In the view of reservoir fluid geochemistry, we have proposed that there exist bacterially-mediated organic-inorganic diagenetic alterations, i.e. hydrocarbon-water-rock interactions in the North Tarim, and that organic acids were formed in situ by biodegradation of crude oils. The proposal is consistent with discussion from pyrolysis experiments. 1 Evidence from reservoir fluid geochemistry 1.1 Chromatographic characteristics of crude oils and extracts Normal crude oils produced from
