A New Method Forecasting Physical and Chemical Properties of the Shale Based on Quantum Neural Network
Abstract:
Influence factors of sidewall stability contain mechanical factors and chemical factors. Among them, the chemical factor is the internal cause of the sidewall instability. Based on the collection of the influence factors of physical and chemical properties of the shale, we decided the main factors that influence the stability through the simple correlation analysis and applied a kind of quantum neural network based on the multilayer excitation function. We established the quantum neural network forecast model of shale physical and chemical properties that can effectively improve the network convergence speed and the accuracy of prediction. The quantum neural network prediction model analysis show that human factors interference of this method is small, and the system parameters needed less, wide application, the result is reliable, can effectively reflect the shale physical and chemical properties and fabric characteristics, to provide a reliable basis for preventing sidewall instability.
