Abstract

Abstract: In order to accurately describe the superposition relationship between individual water channels within the sand body of deep-water turbidite composite channels, we made a quantitative study on Reservoir Z in the AKPO Oilfield in the Niger Basin. The study showed that the various stacking relationships between single sand bodies in deep-water turbidite reservoirs can be quantitatively characterized by the “stacking ratio” parameter. This parameter can be further divided into a vertical stacking ratio and a lateral stacking ratio. There is a certain correlation between the stacking ratio of sand bodies of an individual channel and the camber curvature of the composite channel. In addition, the channel curvature is highly correlated with geological factors such as the slope of the basin and material resource supply. The stacking ratio of sand bodies of an individual channel is correlated to the interior connectivity of the composite sand body, and can be used as a reference for judging the internal connectivity of the reservoir when combined with the ”connectivity coefficient”. This study found that the stacking ratio is an important link. It can be used to build a mathematical connection between the stacking pattern and the morphology of sand bodies, with reservoir connectivity and development effect. It is one of the most effective means of fine characterization and digitization research of deep-water turbidite sand bodies.

Key words: turbidite channel, quantitative characterization, stacking ratio, stacking pattern, sand body connectivity
