| 摘 要： | 本文通过对资阳地区灯影组钻井岩心的宏观、微观及地球化学特征的研究发现，灯影组曾受到多期不同程度岩溶作用的改造，形成了一系列特征的岩溶标志。根据岩溶期次及与储集空间发育的关系等进一步将岩溶划分为同生－准同生期、表生期、中－深埋藏期、褶皱期四种岩溶类型。现今灯影组天然气的储集空间主要受到岩溶作用的控制，是多期岩溶作用长期叠加的结果。

| Abstract: | This paper is based Primarly upon detaited study of Dengying Formation, Later Sinian, from Ziyang are by means of the macro-and micro-analysis, as well as geochemistry, and is caveated that there are series of karst features in dingying Formation which undergone multipha sic kirstification. According to the genetic stage, affeicting factors and associated characteristics,four kinds Of karst can be recognitized, i. e. Syngenesis, hypergenesis, middle- deep buried diagnesis and folding stage. The present reservoir pore space is mainly controlled by karstion it is resultal by superposition of long term and maltiphasic karstification. |
