Geochemical Characteristics and Genesis of Pre-jurassic Heavy Oil in Tainan Sag of Tuha Basin

Turpan-Hami Basin heavy oil mainly distributed in Tainan Sag Lukeqin structure belt, It has so far proven geological reserves of nearly hundred million tons. Heavy oil is a potential hydrocarbon resources, it is limited by the techniques and benefits level, mining is still a certain difficulty, but as unconventional reservoirs in the basin, it is essential to ascertain the geochemical characteristics and thickening reason of heavy oil for further exploration of Jurassic crude oil.
