Research Progress on Enhancement Methods for CO2 Replacement in Natural Gas Hydrate Extraction
摘要
Abstract
The CO2 replacement method for exploiting natural gas hydrates is a technology that sequesters CO2 in the form of solid hydrates in the ocean while utilizing its displacement effect to achieve efficient extraction of natural gas hydrates.This technique synergistically enhances production efficiency during natural gas hydrate extraction process,maintains the stability of seabed formations,and ensure production safety,holding promise for significant technological breakthroughs.To further understand its development prospects,this study systematically outlines its technical advantages and challenges based on fundamental principles and current research.Subsequently,Raman spectroscopy analysis is employed to elucidate the molecular level processes of natural gas hydrate decomposition,CO2 hydrate storage,and CO2-CH4 hydrate displacement.Meanwhile,through the analysis of performance indica-tors such as CH4 recovery rate and CO2 storage rate,methods to enhance CO2 replacement mining including thermal injection,depressurization,chemical additive injection,and hydrate cap formation are further explored.关键词
