以河流作用为主的障壁岛环境中,障壁岛砂坝是油气赋存的主要储集体。受物源供给和海平面升降变化的共同影响,砂坝砂体在空间上整体呈现叠置连片、横向不连通的分布特征,易形成岩性圈闭。因此,有效识别陆源碎屑障壁海岸环境中单个储层并进行含油气性评价是勘探的关键。以阿尔及利亚韦德迈阿盆地B区块泥盆系为例,首先在高分辨层序地层学指导下,识别关键等时标志层——海泛面,划分四级层序,细化研究单元;然后针对储层密集发育段,采用随机模拟反演方法预测砂体分布,岩性指示模拟预测油层横向展布,并结合储层地球物理特征、地震属性参数、沉积规律分析等储层综合预测技术识别有效储层,并进行含油气性评价。利用该方法有效预测了B区块障壁砂坝有效储层的空间分布,预测的砂岩与实际钻井吻合较好,有效探索了陆源碎屑障壁海岸障壁岛砂坝有效储层评价的技术系列。

Focused on the problem that the conventional seismic inversion cannot effectively identify the reservoirs and evaluate the property of hydrocarbon-bearing of the terrigenous barrier reservoirs in barrier coast environment, an analytical prediction method is proposed with a case study of the Devonian of block B in Oued Mya Basin, Algeria. That is within the minimum sequence stratigraphic unit, with the controlling of isochronous framework of flood surfaces, using the stochastic simulation to predict the distribution of sand bodies, the lithologic indication simulation to predict the lateral distribution of oil in reservoir, combining reservoir geophysical, seismic attribute, and deposition analysis and other comprehensive reservoir prediction technology to take effective reservoir prediction of terrigenous barrier bar. The results show that the method can effectively predict the spatial distribution of terrigenous barrier reservoirs in the block B, and the actual drilling is in good agreement with the previous prediction. So, this study and the proposed method successfully explored a technical series for evaluating the effective reservoirs of terrigenous barrier bar.
