| 摘 要： | 川西坳陷侏罗系是川西浅层天然气勘探开发的主要目的层，气藏分布与蓬莱镇组中有利储层的展布密切相关。气藏预测的重点和难点主要在于对有利储层的准确预测。笔者运用层序地层学原理，建立起了川西坳陷上侏罗统蓬莱镇组的层序地层对比格架，经研究发现，有利储集砂体主要发育在中期基准面下降晚期和上升早期，通过分析砂体的沉积，测井，地震等标志，可以确定储层的主要沉积微相。利用储层的多种识别标志，特别是含气砂体的地震识别标志，有效地实现了对有利储层的横向预测。

| Abstract: | The Jurassic strata are considered as the important target strata for the exploration and development of the supergene gas in western Sichuan. The sequence stratigraphic framework of the Upper Jurassic Penglaizhen Formation has been constructed in the light of the principles of sequence stratigraphy. The results of research show that the favourable reservoir sandstones occur primarily in the later stages of base-level falls and the early stages of base-level rises. The sedimentary facies and microfacies may be identified for the hydrocarbon reservoirs on the basis of well logs, depositional and seismic indicators, and the horizontal prediction of the favourable hydrocarbon reservoirs may be effectively made on the basis of several criteria especially seismic ones for the recognition of gas-bearing sandstones. |
