Title: THE DISTRIBUTION OF OOLITIC SHOAL IN FEIXIANGUAN FORMATION OF LOWER TRIASSIC AND ITS EXPLORATION PROSPECT OF GAS IN EASTERN SICHUAN BASIN
Abstract: In the eastern Sichuan basin, the sedimentary environment of early Triassic inherited that of late Permian. The zonation in the platform was obvious with well-developed oolitic shoal. Migration of shoal occurred in the process of platform development. Four relatively thick oolitic rock area could be classified in reference to the drilling data. Mang industrial gas wells have been drilled in the oolitic shoal of Feixianguan Formation in the eatern Sichuan basin.The result showed that the reserriors lay in the dolomite and limestone with solution pore in the thick oolitic rock area where abundant industrial gas reserve has been obtained.Therefore, the oolitic shoal rock in Feixianguan Formation in the eatern Sichuan basin pocessed great exploration prospect of gas.
