陆相生油岩评价中存在问题探讨--以东濮凹陷为例

陆相生油岩评价至少存在2方面问题：第一是以暗色泥岩的评价代替为对源岩的评价，致使源岩厚度评价过高，有机质丰度和源岩品质评价过低，我国陆相源岩厚度评价普遍较高可能主要与此相关；第二是以源岩评价代替对有效烃源岩的评价，致使有效烃源岩厚度、有机质丰度以及有效烃源岩品质评价过高。因此，陆相源岩评价，首先必须确保被评价对象是源岩，其次必须确保源岩是有效的。

Problem Discussion on Evaluation of Continental Source Rocks

At least,there are two problems in the evaluation of continental source rocks.First,dark shale evaluation instead of source rock evaluation,which results in overvalued source rock thickness and lower-valued abundance of organic matter and quality of source rocks.It may be related to this condition that continental source rock evaluation is widely higher in our country.Second,source rock evaluation instead of effective source rocks evaluation,which results in overvalued thickness and quality of effective source rock and abundance of organic matter.Therefore,continental source rock evaluation must aim at effective source rocks.
