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 constrained inversion to improve the resolution of thin sand layers and accurately predict the distribution of sand bodies is one of the new methods for exploration of deep thin sand body lithologic reservoirs. It can not only evaluate the reservoirs being drilled more correctly, but also predict the sand bodies more accurately when the exploration wells are deployed. In this paper, taking the expansion of fan-delta oil and gas exploration at the bottom of the third member of Shahejie Formation in Chexi Sag as an example, the application of multi-well constraint inversion in the exploration of thin-bedded lithologic reservoirs is briefly introduced.
