Abstract: The paper suggests that the Shaya-Luntai Faulting System can be distinctly divided into the east, west and middle sections respectively based on its morphometry and evolutional histories. Be cause of the long duration of faulting activities,and different intensities and properties for each section during various stages,the faulting system wonld be favourable for the controlling over oil and gas occurrence with differdnt levels The Yakcla oil/gas field and the Luntai oil/gas pool controlled by the middle and the east sections, respectively,are two typical examples.
