Geological sub-layer partitioning using well-log data and a CNN–BiLSTM framework: a case study from L block, Ordos basin sandstone reservoirs

To address the challenges of reliance on manual interpretation, high non-uniqueness, and limited accuracy in the geological sub-layer division of the C812 layer in the Yanchang Formation, L block, Ordos Basin, this study proposes an intelligent division method based on a CNN-BiLSTM model. This metho...
