四川盆地西部坳陷南区，即大邑一新津一线以南、龙门山以东、龙泉山以西、名山一丹棱一眉山一线以北约300 km2的地区。近年来在侏罗纪地层中发现了大量工业性天然气藏。侏罗系的层序地层及其与油气关系的研究引起了人们的极大关注。笔者对区内侏罗系采用层序地层学观点进行了详细的野外露头和室内钻井、测井、地震层序分析。在侏罗系中识别出9个层序界面，并划分为8个三级层序。论文对层序地层与油气关系进行了论述，指出区内侏罗系浅气层最有利勘探区为平落坝、大兴西、松花镇、白马庙等地，有利勘探区为蒲江、邛西、观音寺等地。
四川盆地西部坳陷南區，即大邑一新津一線以南、龍門山以東、龍泉山以西、名山一丹稜一眉山一線以北約300 km2的地區。近年來在侏囉紀地層中髮現瞭大量工業性天然氣藏。侏囉繫的層序地層及其與油氣關繫的研究引起瞭人們的極大關註。筆者對區內侏囉繫採用層序地層學觀點進行瞭詳細的野外露頭和室內鑽井、測井、地震層序分析。在侏囉繫中識彆齣9箇層序界麵，併劃分為8箇三級層序。論文對層序地層與油氣關繫進行瞭論述，指齣區內侏囉繫淺氣層最有利勘探區為平落壩、大興西、鬆花鎮、白馬廟等地，有利勘探區為蒲江、邛西、觀音寺等地。

The south part of West Sichuan Depression, being to the south of Dayi-Xinjing, the east of Longmen Moun tains, the west of Longquan Mountains and the north of Ming shan-Danling-Meishan, occupies an area of about 300 km2. In recent years, a large number of commercial gas reservoirs have been found in Jurassic, which arouses a great interest in the re search on the sequence stratigraphy of Jurassic and its relation to hydrocarbons. By use of the view points of the sequence stratig raphy, the outcrops and the drilling well-logging and seismic se quence data were analyzed in detail. In Jurassic, nine sequence interfaces were identified and eight tertiary sequences were clas sified. The relationship between sequences and hydrocarbons is discussed in the paper. It is pointed out that the most favourable regions of exploring for shallow gas in Juassic are Pingluoba, Daxinxi,Songhuazhen and Baimamiao, etc., and the favourable regions are Pujiang, Qiongxi and Guanyinsi,etc.
