Source identification and accumulation restoration of complex oil reservoirs in Mahu Sag, Junggar Basin
Published 2024-01-01“…These oils are divided into four groups: group I oils (characterized by high β-carotane and gammacerane concentrations, low C 21 /C 23 and (C 19 + C 20 )/C 23 tricyclic terpane ratios, and low Pr/Ph ratios); group II oils (characterized by low β-carotane and gammacerane concentrations, high C 21 /C 23 and (C 19 + C 20 )/C 23 tricyclic terpane ratios, and moderate Pr/Ph ratios); group III oils (very high Pr/Ph ratio (>3), the lowest β-carotane and gammacerane concentrations, and low tricyclic terpane concentration, but relatively high C 19 and C 20 tricyclic terpane abundance); and group IV oils (refered to here as geochemically hybrid, and inferred to be sourced from mixed P 1 f and C/P 1 j source rocks). The integration of oil-source correlation and geological framework indicates that oils generated from multiple kitchens are more likely to be near-sourced accumulations, providing a plausible example for oil accumulation in a complex oil reservoir of superimposed basin with several sets of kitchens and multistage oil charging history. …”
