Based on the well logging knowledge graph of hydrocarbon-bearing formation (HBF). a Knowledge-Powered Neural Network Formation Evaluation model (KPNFE) has been proposed. It has the following functions: (1) extracting characteristic parameters describing HBF in multiple dimensions and multiple scales; (2) showing the characteristic parameter-related entities. relationships. https://fitnessgravesyardes.shop/product-category/optical-speed-sensor/
