| 摘 要： | 为预测大庆徐家围子断陷营城组火山岩储层有利相带的分布,对火山岩储集性的控制因素进行了分析。岩芯和薄片观察表明,原生孔隙是火山岩储集空间形成的基础,次生孔隙是储集空间的重要组成部分。通过对火山岩孔隙类型的统计,结合对岩芯物性的对比分析,发现控制火山岩储集性的主要因素有火山岩岩相、构造裂缝和酸性流体的溶蚀作用等。不整合面下方火山机构地貌突出且火山岩溶蚀强烈的部位应该成为今后重点勘探的区域。

| Abstract: | To predict the distribution of the favorable volcanic facies belts of Yingcheng Group in Xujiaweizi Depression, it's necessary to analyze the factors to control the reservoir capabilities of the volcanic rocks. Observation of cores and thin sections indicates that primary pores are the basic reservoir space of the volcanic rocks, while secondary pores have important influence. Through statistics of the pore types and comparison of the physical properties of the volcanic rocks, the authors find that the control factors of the volcanic reservoir capabilities are lithofacies, fractures, and dissolution by the acidic fluid. The formations that have been dissoluted under the unconformities on top of the volcanic edifices near the main faults will be the most important exploration targets. |
