摘要
运用多井约束反演提高薄砂层的分辨率,准确预测砂体的分布,是深层薄砂体岩性油气藏勘探新的方法技术之一。它既可以对正钻井的储集层进行比较正确的评价,又可以在探井部署时对砂体进行比较准确的预测。本文以车西洼陷沙三段底部扇三角洲砂体油气勘探的外扩为例,简单介绍了多井约束反演在薄层岩性油气藏勘探中的应用。
Using multi-well logging data to constrained inversion enhances the ability to discriminate thin-bed sand bodies and correctly predicts their distribution. It is one of new techniques used for exploring deeply buried thin-bed sandstone lithological reservoirs. This method can not only be used for accurately evaluating reservoir while drilling, but also can accurately predict sand bodies for the correct arrangement of exploration Wells. In the article, taking the fan-delta sand body on the bottom of Sha-3 formation in Chexi Depression as an example of extensional exploration, a simple introduction of this constrained inversion technique is made.
