Abstract: Turpan-hami basin has belonged to a foreland basin since Jurassic era. Following Middle Jurassic period, Taibei sag became a major part of its northern foreland depression and formed a series of foreland thrust belts during Yanshan and Himalayan movements,including north marginal pediment nappe belt,middle central faulted fold anti- cline belt and south marginal Huoyanshan-Qiketai front belt. So far great amounts of oil and gas have been found in the central anticline belt. Although little hydrocarbon has been discovered in both south marginal front belt and north marginal pediment nappe belt, it is believed that they have big potentials for petroleum prospecting. Owing to complicated geologic and topographic conditions, corresponding key technologies are needed. Some experiences and measures have been accumulated nowadays.

Key words: Turpan-hami basin, Jurassic, foreland basin, tectonic evolution, explorative achievement
