【摘要】 气烟囱是由热流体活动形成的一种特殊的伴生构造。其一经形成后 ,对后期幕式活动的热流体或油气运移仍为一种特殊的运移通道 ,而且影响油气的聚集成藏。本文对气烟囱形成机理和演化特征进行了研究 ,探讨了气烟囱与油气生成、运移、聚集的关系 ,并通过光测弹性力学模拟和物理相似模拟等实验方法进行了验证。结果表明 ,在中国东部油气勘探中 ,气烟囱研究不仅可预测浅层油气藏分布 ,而且为寻找深层有机、无机气藏提供科学依据更多还原

【Abstract】 The gas chimney is a specially associated structure formed by the hot fluid flow in the sedimentary basin. After it was formed, the gas chimney is still a special transportation channel to the hot fluid and petroleum with scenal action later. It can affect the petroleum accumulation and generation. This paper deals with the formation mechanism and evolution feature of the gas chimney through photoelastic simulation experiment and other methods. The main relationship between the gas chimney and the formation, migration and accumulation of petroleum is approached. The result indicates that the study of gas chimney could not only predict the distribution of the shallow pools, but also provide the scientific basis for searching for the deep organic and inorganic pools in the petroleum exploration of East China.更多还原
