当不能确定岩性和成岩历史的复杂变化是否会导致储集层的非均质性时,不好的油藏特征会给勘探和开发带来困难。优化油田开发方案需要对油藏的垂向和横向进行精细描述。文中说明了如何将地质学和岩石物理学结合起来研究油藏特征,所用的数据取自尼日尔河三角洲砂岩油藏。
Poor reservoir characteristics can make exploration and development difficult when it is not possible to determine whether complex changes in lithology and diagenetic history can lead to reservoir heterogeneity. Optimizing oilfield development programs requires a detailed description of vertical and horizontal reservoir. The article explains how to combine geology and petrophysics to study reservoir characteristics, using data taken from sandstone reservoirs in the Niger Delta.
