东濮凹陷泥页岩盖层测井评价

根据油气藏生成原理。盖层是油气聚集形成油气藏的一个重要条件。盖层封隔性能的好坏直接影响着形成油气藏的质量。即使一个油气藏形成以后。上覆盖层质量的破坏。也会影响油气的聚集，导致油气逸散。因此，为更准确地做好测井解释工作。测井分析应不仅对储层进行研究。还需对盖层的封闭性能进行评价。

Evaluation shale cap Rock of Dongpu Depression Using Well Logging date

According to theory of reservoir creating.Cap rock is an important qualification of reservoir forming,quality of a reservoir is affected directly by confining property of cap rock .So,not only reservoir research but also evaluation of confinement of cap rock should be done in well logging evaluation .Based on shale cap rock confining mechanism in Dongpu depression ,some important facts in evaluation of shale cap rock are analyzed ,a method is summarized to evaluate confining property of cap rock using logging data,and it is proved by some instances that validity of cap rock should be evaluated correctly while logging data is processed and imterpreted conventionally so as to improve the accuracy of well logging interpretation.
