东营三角洲储层具层薄、侧向叠置特点,常规地层对比、储层预测方法,难以有效预测薄砂层分布规律,致使砂层注采连通关系认识不清.本文以唐家河长期注水开发、水淹严重的东三段储层为例,应用层序地层学OpendTect 储层识别软件,对东三段6 m以上砂层进行横向追踪预测.该软件做出比地震解释界面更精细的微层序,准确描述出砂体空间展布,刻画出高产层砂体边界.在此基础上,部署了区块调整方案,实施效果显著,该项技术对薄砂层识别与追踪具辅助作用.
東營三角洲儲層具層薄、側嚮疊置特點,常規地層對比、儲層預測方法,難以有效預測薄砂層分佈規律,緻使砂層註採連通關繫認識不清.本文以唐傢河長期註水開髮、水淹嚴重的東三段儲層為例,應用層序地層學OpendTect 儲層識彆軟件,對東三段6 m以上砂層進行橫嚮追蹤預測.該軟件做齣比地震解釋界麵更精細的微層序,準確描述齣砂體空間展佈,刻畫齣高產層砂體邊界.在此基礎上,部署瞭區塊調整方案,實施效果顯著,該項技術對薄砂層識彆與追蹤具輔助作用.

Dongying Delta Reservoir has the characteristies of thin reservoir thickness and lateral overriding,it is difficult to predict the distribution rules of thin sandstone using conventional correlation of strata and prediction method.and this led to understanding the relationship between injection and production connectivity unclearly.In this paper,taking long-term water flood development,serious flush Section Ⅲ Dongying Formation of tangjiahe oil field as an example,sand body about 6 m thickness can be traced laterally in Section Ⅲ Dongying Formation With the help of the software "Opend Tect" which under the guidance of Sequence stratigraphy theory."OpendTect" is able to make the interface more fine than the seismic interpretation interface,describe the space through-going accurately,depict sand body boundary of high productivity reservoir.Based on above research result,development plan has a good result after the implementation.This technique has a good supporting role in identification and trace of thin sand.
