Wu Shixiang, Wang Zecheng, Zhang Lin, et al. EXPLORATION STRATEGY FOR THE FORELAND BASIN IN WESTERN SICHUAN[J]. 2001, 22(3): 210-216.DOI: 10.11743/ogg20010304.
combining with the distribution of oil and gas in Upper Triassic and Jurassic in the foreland basin in western Sichuan
the traps within the study area could be classified into structural and structural lithologic traps.It is pointed out that there are four major exploration areas in the west of Sichuan Basin:structural trap area along the Longmen Mountains including Upper Triassic Series and Jurassic System
deep basin gas in the depressions
structural lithologic trap area in the pinch out area of the second member of Xujiahe Formation along the foreland basin uplift
and shallower gas direction area in Jurassic System in the ancient Yanshan uplift.Different exploration strategies should be adopted in different areas and belts in the basin.
