| 摘 要： | 渤海湾盆地许多地区的泥质岩地层中都发现了工业油流,做为一种非常规的油气藏,其分布特征主要表现为:①分布在成熟的烃源岩中,为自生自储型;②泥质岩油气藏主要位于超压泥质岩微裂缝带内,该带在垂向上集中分布在一定区间,平面上可以区域对比;③泥质岩油气藏主要受构造活动控制,集中分布在断层带附近。根据有关油气初次运移的模拟试验及相关理论,认为泥质岩油气藏的形成与混相涌流有关,断裂活动是导致油气在生油岩内顺层定向富集的主要诱因。在这种认识的基础上,初步探讨了泥质岩油气藏勘探的关键技术。

| Abstract: | Argillaceous hydrocarbon reservoirs in Bohai gulf basin,as a kind of unconventional hydrocarbon-bearing pool,have the following distribution characteristics:(1)they are distributed in mature source rock and source rock and reservoir rock are in the same layer;(2)argillaceous reservoirs are mainly located in the over-pressured microfracture zone;(3)they are controlled mainly by structural activities.It is believed that the de-velopment of argillaceous reservoirs has something to do with miscible shove and that fracturing is the key cause of parallel directional enrichment of hydrocarbon based on simulation test of primary migration of hydrocarbon and the relevant theories.The main techniques for ex-ploration of argillaceous reservoirs are discussed in this paper. |
