ADVANCES IN THE STUDY OF GAS AND SOURCE ROCK CORRELATION
天然气气源对比研究方法进展

Source rock correlation research has important practical and theoretical significance in the field of oil and gas exploration and development. Isotope geochemistry has been playing an important role in the gas and source rock correlation. Component carbon, hydrogen stable isotope of natural gas can identify source rock, thermal evolution of source rock, and accumulation process of natural gas. Noble gas isotope has been widely used to identify sources of natural gas. In recent years, some other methods are developed such as the method using fluid inclusions, benzene, toluene, xylene, methyl cyclohexane and other light hydrocarbons to study gas and source rock correlation, the direct contrast of gas source to the detailed anatomy of gas components, and the dynamic comprehensive comparison method. This paper introduces the development and innovation of gas and source rock correlation and its development trend in the future.
