根据烃源岩的生气强度、断裂输导天然气效率和新近系盖层厚度条件进行叠合，对库车坳陷北带天然气成藏与分布的有利区进行预测。

This paper briefly introduces the basic fact of the existence of the PaleoTethys Ocean in the Lungmu Co-Shuanghu suture, i.e. the ages and natures of Early Paleozoic ophiolites, Permian ophiolites, Devonian-Permian radiolarian cherts, accretionary slabs of different natures, two types of tectonic mrlange zones and covers of ophiolites. The starting time of the Paleo-Tethys Ocean in Qiangtang may be traced back to Early Paleozoic and the records about the oceanic basin evolution persisted from the Late Devonian to Late Triassic.

It is a megadepression evolving from a Mesozoic back-arc paraforeland basin to a Cenozoic intermountain basin, and filled with large sets of argillaceous rock, calcareous mudstone, carbonate rock and clastic rock of saliniferous-semisaliniferous environment under the semidry climate of inland lakes which form a set of giant-thick hydrocarbon source rock with two periods of hydrocarbon-expulsion peaks, two types of reservoir series as well as special capping and migration conditions.
