摘要
作为油气运移的重要通道 ,断裂的不同部位对油气的输导能力具有很强的不均一性 ,从而造成沿油源断裂分布的油气圈闭具有明显的油气差异聚集结果。断面优势运移通道的提出改变了以往人们认为开启的断裂都是油气运移通道的错误观念 ,强调只有沿着断面优势运移通道寻找勘探目标 ,才可能发现油气藏。本文通过分析断裂带输导能力的不均一性 ,提出断面优势运移通道概念及其油气汇聚运移原理 ,断面优势运移通道分析步骤和方法 ,并以柴达木盆地北缘几条主要的控油气断裂为例 ,分析了不同部位油气运移的优势运移通道并对其附近的油气圈闭含油气性进行了评价 ,结果与勘探成果相符。
The different part of a fault has different capability carrying petroleum to migrate, although the fault is one of the most important petroleum migrating channel. This results a various petroleum accumulation difference in the traps distributing along the same fault. The concept of fault section dominant migrating channel changes the error viewpoint of “each part of the whole opening fault are all the petroleum migrating path”, this paper emphasizes that exploration maybe find petroleum accumulation only according the fault section dominant migrating channel, and point out the concept of fault section dominant migrating channel and its principle accumulating petroleum to carrying it as well as its study method by analysis the non-homogeneous of fault zone carrying petroleum capability. At last, this paper use the method to analysis the main controlling petroleum faults features of carrying petroleum to migrating in the north margin of Qaidm Basin, and point out the petroleum migrating dominant channel in these faults and appraise some traps distributing along these faults, the results of studying and appraising are unanimous conclusion with the exploration.
