摘要
川西及邻区蓬苹镇组厚９５０～１６００余米，属侏罗纪湖盆萎缩期的沉积。据层序界面及最大水进面联合标定，划分出Ⅲ３和Ⅲ４两套沉积层序。通过沉积基准面旋回分析，论述了蓬莱镇组沉积相类型及时空展布特征，预测了有利相带，并对有利油气富集区块进行了划分。
The Penglaizhen Formation in West Sichuan and adjacent areas is thick over 950 1600m,which was deposited during the wilting period of the Jurassic lake basins.Based on the combined demarcation of sequence interfaces and maximum transgressive interfaces,Ⅲ 3 and Ⅲ 4 two sets of sedimentary sequences are classified.By analyzing on the cycles of sedimentary base levels,the sedimentary facies types and apace time distributive characteristics of the Penglaizhen Formation are discussed,the favorable facies tracts are predicted,and the favorable hydrocarbon enriched blocks are classified.
