砂泥岩薄互储集层地震预测研究
|
摘要
随着油气勘探开发程度的不断提高,强非均质性砂泥岩薄互储层的研究与评价越来越受到重视。文章以某油田花港组储层为例,针对强非均质性砂泥岩薄互储层的地层特征和岩性及含油气性与波阻抗相关性差的资料特点,研究探索出一套与之相适应的储层预测方法与流程,并对储层的分布规律进行了预测,从而为该构造的储量计算及油藏模拟工作奠定了基础,并为波阻抗与岩性相关性较差条件下强非均质性薄互储层的预测提供了可借鉴的技术思路。
With further exploration and development of oil and gas,research and evaluation of thin sand-shale interbed reservoirs which have strong heterogeneity are paid more and more attention to.Taking reservoirs in Huagang group of an oilfield as an example,a suitable method and flow for reservoir prediction has been searched out which was used to predict the distribution law of reservoirs according to the characteristics and lithology of the anisotropic interbed reservoirs and features of poor correlation between oiliness and wave impedance.It has laid a solid foundation for calculation of reserves and reservoir modeling.It also provides a technical idea for interbed reservoir prediction under the condition of poor correlation between wave impedance and lithology.
