Abstract: Petroleum Geology of Giant Oil and Gas Fields in Turpan Basin, Xinjiang, China

Boliang Hu, Yang Jiajing

Turpan basin is the smallest and the last development basin in three big basins of Xinjiang autonomous region, P. R. China. Since April, 1989, the Shanshan oilfield was discovered, the Oinling, Wenjisang, Midang, Baka, Qiudong and North Putaogou fields were discovered. In 1994, the crude oil productivity of Turpan basin was a Million tons, with an estimated output of 3 million tons per year by 1995; obviously a key oil productive base in the west basins of China, Tarim, Jungar, Chaidam, Hexi, Erduos and Sichuan basins.

The Turpan basin is an intermontane basin in a eugeosyncline fold--belt of the north Tianshan Mountains. The oil and gas was produced from the payzone of the Xishanyao, Sanjianfang and Qiketai Formation of the Middle Jurassic series. The geochemical characteristics of the crude oil and gas indicate they derive from the Middle to Lower Jurassic coal series, in which contains the best oil--prone source rocks in the basin.
