Real-time inversion method of multi-measurement point and multi-parameter drilling, device, media and product

A real-time inversion method of multi-measurement point and multi-parameter drilling, comprising:

• acquiring downhole measurement data of target drilled well;
• wherein the downhole measurement data is measured in real time based on an intelligent microsphere along a drill pipe;
• establishing a real-time inversion interpretation model for a downhole gas kick condition based on a wellbore multiphase flow forward model and an adaptive unscented Kalman filter algorithm according to the downhole measurement data;
• wherein the wellbore multiphase flow forward model is a mathematical model which is constructed for a heat transfer and mass transfer process of wellbore multiphase flow resulted from the downhole gas kick condition based on a theory of wellbore multiphase flow and heat transfer;
• the adaptive unscented Kalman filter algorithm is an optimal estimator suitable for nonlinear time-varying noise interference which is constructed after introducing an adaptive factor into an unscented Kalman filter;
• and
• inputting the downhole measurement data into the real-time inversion interpretation model for the downhole gas kick condition to obtain an inversion parameter of the target drilled well.
