| 摘 要： | 本文运用古水文地质学的分析方法,从历史的、岩溶的角度对威远构造阳新统顶部天然气储集空间—缝洞系统的演化过程分期进行了探讨。文中运用传统的古水动力恢复方法及物理和数值模拟方法对每期的古水文地质条件进行了再现,得出了本区阳新统顶部缝洞系统的三个有利分布带,其中之一已为若干勘探成果证实。

| Abstract: | Investigations are made by using Paleohydrogeological analysis of the evolutional process of the fissure-cave systems in the top part of the Yangxing Formation, systems where natural gas is abundant. A traditional method-that of paleohydrodynamic restoration- is employed together with the modern physical and mathe-matic mcdelling, to relive the paleohydrogeological conditions of each period, and three favourable zones are found, one of which has been confirmed by geological explorations in this area |
