摘要:

通过分析临清坳陷东部煤成气成成藏条件,对已知的钻井显示进行了总结,研究了不同时期供气区分布范围及供气强度,探讨了煤成气藏的分布规律。研究结果表明,堂邑背斜带东部斜坡是煤成气成藏的有利勘探区带,其上邻近供气中心,由反向断层遮挡形成的石炭―二叠系和奥陶系的顶部圈闭,这些都是煤成气勘探的有利目标。

Abstract:

It is discussed in this article that what conditions are required for the formation of coal-formed gas pool in the eastern Linqing depression.The known gas shows in wells are summarized and discussed. We also study the distribution ranges of gas supplying zones and their gas supplying density. The research result shows that the east slope of Tangyi anticline belt is one of the favorable areas for coal-formed gas exploration.The favorable targets are traps of Carboniferous-Permian System and of the top of Ordovician System which are formed by seals of antithetic faults.

Key words: the eastern Linqing depression, coal-formed gas, pool formation conditions, pool distribution, exploration direction
