Method for predicting mechanical drilling speed based on micro-inclination characteristics

The application discloses a mechanical drilling speed prediction method based on micro-inclination characteristics, comprising the following steps: acquiring real drilling wellbore logging while drilling and logging data as a first data set; preprocessing the first data set and extracting the best feature and the micro-inclination feature as input features; the preprocessing comprises data cleaning and correlation analysis; training a mechanical drilling speed prediction model by using the input features; and predicting the mechanical drilling speed of a target well by using the trained mechanical drilling speed prediction model. The micro-inclination feature introduced in the application can significantly improve the ROP prediction accuracy of the model. By introducing the micro-inclination feature in the MLP neural network, the model weight is optimized, and the prediction accuracy of the ROP is improved. By introducing the micro-inclination feature in the SVR model and selecting the optimal hyperparameter, the prediction effect is significantly improved. The method provides a new idea for improving drilling parameter prediction and control by using machine learning, and can be applied to the optimization of drilling speed and efficiency.

A method and system for intelligent hazard detection based on image recognition

This invention relates to the field of intelligent inspection and image analysis technology, and discloses an intelligent hazard investigation method and system based on image recognition. The method includes establishing a hazard knowledge network representing the correlation between hazard types, features, and causes. Hazard images are collected during inspections and input into the network. Hazard entities are extracted, and their features are matched with hazard features in the network. Network reasoning is used to obtain the associated hazard types and causes. Hazard probabilities are calculated based on the correlation strength of causes. Intelligent investigation tasks bound to locations are generated and output based on a comparison of the probability and a threshold to guide targeted investigations. Finally, the correlation relationships in the hazard knowledge network are optimized based on feedback from on-site verification of the tasks. This invention achieves intelligent hazard identification and cause reasoning through a knowledge network, and optimizes the network using a closed-loop business feedback mechanism, improving the intelligence depth of hazard investigation and the system's adaptability.
