| 摘 要： | 坨 -胜 -永断裂带到目前为止发现了 1 1个中层气藏 ,几乎都与断层活动有关 .为了弄清坨 -胜 -永断裂带中层气藏形成中断层的控制作用 ,通过井与井之间的分析对比 ,并对部分井进行包裹体分析 ,得出以下结论 :1超压流体活动应是坨 -胜 -永断裂带油气运移的主要动力和载体 ;2断层封闭主要为泥质涂抹和断裂破碎带封闭 ;3中层气的甲烷含量高应与运移分异有关

| Abstract: | In Tuo Sheng Yong faulted zone, 11 middles gas pools were found, and their formation is related to the activities of the faults. In order to understand the control action of faults to the formation the middle gas pools in Tuo Sheng Yong faulted zone, the data of Tuo 9, Yong 31 and Yong 554 wells are analyzed and contrasted, and it is concluded that, overpressure fluid is the main dynamic force and carrier of oil gas migration; the sealing of faults is mainly mud daubing and the rock fragment of broken faulted belts; the high content of CH 4 in the middle gas pools is related to the differentiation of oil gas migration. |
