Abstract
Oils from Well Tadong2, Tarim Basin, characteristic of high density, high viscosity and heavy carbon isotopic composition, are marine oils due to compositional features of light hydrocarbons, cyclicterpanes, steranes and triaromatic steranes. It can be seen that oils from Well Tadong2,Tarim Basin, are derived from Cambrian source rocks based on age-specific biomarker correlation studies. Recent oil compositional characteristics are probably related with the influence of high temperature geologic thermal event evidenced by pyrobitumen within reservoirs, PAH in aromatic fractions and carbon isotopic composition of alkanes
