As an anticline, Structure Tadong2 was formed originally at late Silurian stage, and was shaped at late Triassic. Based on the detailed interpretation of 2-dimensional seismic profiles of Structure Tadong2,3-dimensional seismic profiles of Wellblock Tadong2 and the 2-dimensional seismic profiles of the eastern Tarim Basin, the fault system of Structure Tadong2 was established.It mainly contained two subfault systems: the Mesozoic fault system and the Paleozoic fault system, these two subfault systems were both controlled by the north thrusting fault system which contained Cheerchen Fault.Tadong2 Structure contains mainly Cambrian oil source rocks and two series of source-cover mixes in Sinian and Cambrian, and is a series of potential source-cover mixes in pro-Sinian rocks, so the anticline structure has a good exploration prospect of oil and gas. The fault system plays the most important role in improving the reservoirs. On the other hand, it may also destroy the oil and gas source.
