Abstract: The present disclosure provides a method for calculating wellbore friction resistance of a foam drainage gas production well. It is based on the conversion of the parameters of the gas-liquid two-phase flow Mukherjee & Brill model, it defines the liquid film reversal point as the zero friction resistance point, ignores the influence of the negative value of friction resistance, and uses this as a starting point to predict the change of friction resistance. The influence of liquid phase parameters and foaming agent concentration is taken into account in the friction resistance coefficient. An effective calculation method is obtained by combining the experimental data fitting and optimization. The present disclosure better characterizes the wellbore flow condition of the foam drainage gas production well, and provides important theoretical support for the prediction of the wellbore pressure drop of the foam drainage gas production well.

Abstract: Introduced are a method, a software apparatus, an electronic device, and a storage medium for simulating inerter using finite element analysis. The method involves: acquiring structural parameters of an inerter; simulating the mechanical properties of racks on rigid rods and flywheels within the inerter using the structural parameters and a finite element platform; formulating constraint equations and transformation formula to simulate translational-rotational conversion and inertia amplification mechanism of the inerter; integrating the force and constraint information to achieve the finite element simulation of the inerter. The finite element simulation method for the inerter addresses the challenge of lacking “inerter units” and the inability to simulate inertia components in general finite element software platforms. It also overcomes the technical bottleneck of real-time dynamic coupling simulation between inerter and complex engineering structures.
