| 摘 要： | 风化店火山岩主要为钙碱性酸性火山岩,少量碱中性和碱中酸性火山岩.其主要储集孔隙为原生气孔和次生溶蚀孔(洞),构造裂缝及风化裂缝在油气运移过程中主要起输导管作用.火山岩可划分出三个岩相带:火山爆发相、火山溢流相和火山沉积相.火山岩体的储集性能与这三个相带密切相关,油气主要分布在火山爆发相和火山溢流相带.

| Abstract: | The volcanic rocks in Fenghuadian area are composed mainly of calc-alkaline acidic volcanic rocks, containing a small amount of alkaline intermediate or intermediate-acidic volcanics. The main oil reservoir porosities in the rocks are primarily vesicles and secondary dissolution openings. The structural and weathering fissures or cracks just were the carrier for transporting petroleum. The volcanics can be divided into three lithofacies :volcanic explosive facies,effusive facies and volcano-sedimentary facies. The reservior properties are closely related with the three facies. Oil is mainly distributed in the explosive and effusive facies. |
