摘要:

根据中东地区鲁卜哈利盆地古生界不同沉积相储集砂体的地震反射构型不同,运用地震资料精细解释与地震沉积学、层序地层学相结合的方法,对盆地东部已钻井区辫状河道和三角洲前缘砂体的沉积特征与地震反射构型特征进行了识别分析;并由此类比到西部地区进行储层预测,在沉积环境相同的T构造区古生界志留系三级基准面旋回TS3下降期,识别出与东部反射特征相似的两套地震反射体,分别预测为辫状河道和三角洲前缘砂体;以此为依据提交的井位建议得到采纳,实钻后证实预测砂体存在。

Abstract:

According to the different seismic reflection configuration characteristics of delta and fluvial reservoirs, seismic data interpretation, and sedimentary and sequence stratigraphic technique are used to analyse and recognize good reservoirs synthetically.In the east part of Rub Al’Khali basin of Middle East area, there exist some typical seismic reflection characteristics of braided channel and delta front sandstone.Based on these characteristics two sandbody reservoirs are recognized in TS3 basic level cycle of Silurian strata in T structure trap area in the west part of Rub Al’Khali basin, which are predicted as braided channel and delta front sandstone respectively.Reservoir, hydrocarbon accumulation and trap conditions show that the Silurian trap of T structure is a potential exploration region.The proposed well location on T structure is accepted and the later drilling result has verified the predicted reservoir sandstones.

Key words: Rub Al’Khali basin, Paleozoic, seismic reflection configuration, sedimentary, sequence stratigraphy, reservoir predictio
