This invention discloses a drilling lithology identification method based on enhanced dynamic behavioral features. Addressing the shortcomings of traditional methods that rely solely on instantaneous parameters and struggle to capture the dynamic evolution of the drilling process, this method first collects drilling engineering parameter sequences and constructs a depth-domain parameter matrix using a sliding window. Then, it extracts dynamic behavioral features such as parameter change rates, local fluctuation intensity, and dynamic coupling relationships between parameters, and concatenates these features with the original parameters. Next, it constructs a Transformer encoder, utilizing a self-attention mechanism to capture long-range dependencies in the depth sequence. The encoded features are then processed through average pooling and a fully connected layer to output lithology classification probabilities. Finally, a cross-entropy loss function weighted by dynamic responses is used to optimize the model. In validation tests on six wells in the Volve oilfield, this method significantly improved the accuracy of lithology classification and the stability of the model, providing reliable technical support for intelligent drilling.
