Base on the full analysis to the existing data and current research efforts, this paper determined the distribution range of Carboniferous in Delingha Depression by field investigation combined with seisimic data, gravitational data, magnetic data and electrical prospecting data.

Combining the field petroleum geologic review on the outcrops with the well and seismic information,the mudstone,carbonate rock and coal-measure hydrocarbon source rocks in the Mesozoic Jurassic and Paleozoic Carboniferous are considered widely developing in the Delingha Fault-Depression.

Sidaogou is the only locality to discover a little oil and gas in the exploration of the Hami Depression.

The stratigraphy of Upper Persian-Triassic sequence in Hami depression is studied based on geological, seismic, logging and geochemical data.
