| 摘 要： | 徐家围子断陷大型火山岩气藏的发现,揭开了我国火山岩气藏勘探的序幕。以实际钻井资料为基础,应用地质、地球物理以及地球化学相结合的分析方法,探讨了徐家围子断陷火山岩气藏成藏机制。结果表明:充足的气源不仅是气层形成的物质基础,而且控制气藏的宏观分布;基底断裂控制着火山岩呈条带状或串珠状展布,也是天然气运移的输导通道,控制着火山岩气藏的平面及纵向富集区域;火山岩相和火山旋回控制储层发育状况,多旋回喷发的火山岩上部储层较为发育,决定了气藏的垂向分布;区域与局部盖层的分布,控制着火山岩气藏的保存。综合天然气藏分布的主控因素认为,安达凹陷东部、徐东深凹带、徐西斜坡、宋站隆起为下一步最有利的勘探区。

| Abstract: | The discovery of large volcanic gas reservoir in Xujiaweizi fault depression has promoted the exploration of volcanic gas pools in China.Based on data from drillings formation mechanism of the volcanic gas reservoirs is researched in Xujiaweizi fault depression by means of geological,geophysical and geochemical method.The results show that source rock is the first controlling factor for the reservoir,in that it is the material basis on one hand and controls distribution of gas reservoirs on the other hand.B... |
