Application of Molecular Dynamics Simulation to Metal Corrosion and Protection in Oil and Gas Fields
Currently,oil field exploitation is facing increasingly complex working conditions such as high temperature and pressure,high Cl-,and high sulfur content.The corrosion resistance of petroleum pipes and the applicability of protective technologies face significant challenges.Molecular dynamics simulation technology,due to its unrestricted experimental conditions and wide-scale characteristics,can make up for the shortcomings of traditional evaluation methods.This article first outlines the basic principles of molecular dynamics simulation technology;Based on the application of molecular dynamics simulation,the molecular dynamics corrosion mechanism of pipes in Cl-,CO2/H2S and other systems was studied.Summarized the research application of molecular dynamics in the study of anti-corrosion coatings.Finally,the development directions faced by molecular dynamics simulation technology in the future research and development of corrosion-resistant materials were prospected,in order to provide theoretical basis and technical support for the development of new materials for oil and gas fields and the application of protective technologies.
