As the first marine Paleozoic giant oilfield in China and an oilfield dominated by palaeokarstic reservoir of Ordovician carbonate rock

Tahe is located on the southern Akekule Salient of Shaya Uplift

the northem Tarim Basin

with its reserves over 1 billion tons.The obtained results and knowledge about the oilfield are summarized by us in tectonic evolution

sedimentary patterns

reservoir features and hydrocarbon accumulation models.It has been practically demonstrated that continuous enrichment and improvement of petroleum geology theories on Paleozoie marine carbonate in Tarim Basin is a foundation for discovering Tahe oilfield and extending towards its periphery and deeper intervals

and that the mature

whole and effective exploration technology is a tool to make major discoveries.
