Detection Technologies and Quantification Methods for Methane Leakages in Oil and Gas Industry
Methane(CH4)is an important greenhouse gas,and its increasing concentration in the atmosphere year by year is an im-portant factor contributing to global warming.The oil and gas production is an important source of atmospheric CH4 emissions and quantifying the total CH4 emissions from these processes is of great scientific significance for achieving carbon peak and carbon neu-trality.This paper summarizesd the CH4 emission detection technologies,methodologies and quantification methods in oil and gas in-dustry.CH4 detection technology in oil and gas industry mainly introduces optical technology and sensor technology,focusing on the advantages and disadvantages of these technologies.The two detection methods can make up for each other's shortcomings,achieve high-precision and high-resolution CH4 leakage detection in oil and gas industry,and increase the accuracy of regional source inventory investigation.Unmanned aerial vehicles(UAVs)equipped with CH4 laser sensors are more flexible and less costly,serving as an effective complement to existing ground-based and high-altitude detection methods.This makes them an ideal tech-nology for detecting small-scale CH4 leak detection in oil and gas industry,achieving accurate accounting of CH4 leakage by detect-ing CH4 emission fluxes.The methods for quantifying CH4 emissions in oil and gas industry mainly include the reverse deduction method,the flux method,the tracer method and the mass balance method.The selection of reasonable detection technology and sci-entific quantitative methods is helpful to accurately delect and calculate the CH4 leakage in oil and gas industry and provides im-portant technical support for the scientific guidance of CH4 emission reduction in oil and gas industry.
