Abstract: The main elements of China’s domestic oil and gas market became diversified as the reform of the national oil, gas and mineral resource was accelerated. It is of vital importance to establish the reserve value-assessing system suitable for China’s market trading. This article analyzes a large amount of international oil and gas reserve trading cases and summarizes the relations of trading prices with reserves of the different grades, the different producing degrees and the different resource types. Following analysis of the law for trading price variations under the high, middle and low oil prices, the article draws the conclusion that the grade, area and producing degree of reserves are the important factors influencing reserve trading. The certainty of reserves is in positive proportion to the development ratio and the average price of single-barrel reserve while the reserve-production ratio is in reverse proportion to the average price of single-barrel reserve. The single-barrel trading price of confirmed reserves is relatively higher in Australia and North American region. Of the unconventional reserves, the single-barrel price of compact oil/shale oil is higher than the prices of compact gas/shale gas and CBM. The article also comes up with the experience formula for oil and gas reserve trading prices under the marketing conditions, providing the references for establishment of China’s oil and gas reserve value-assessing method.

摘要： 随着国家油气矿产资源改革加快，国内油气市场主体多元化明显加快，建立适应我国市场交易的储量价值评估体系显得尤为重要。通过分析大量国际油气储量交易案例，总结交易价格与不同级别储量、不同开发程度储量、不同资源类型储量的关系，以及高、中、低油价下交易价格之间的变化规律，认为储量级别、地区和开发程度是影响储量交易的重要因素，储量的确定性和已开发占比与单桶储量平均价格呈正比，储采比与单桶储量平均价格呈反比。证实储量的单桶交易价格在澳大利亚和北美地区较高，非常规储量中，致密油/页岩油的单桶价格高于致密气/页岩气和煤层气。提出市场途径下油气储量交易价格的经验公式，为建立我国油气储量价值评估方法提供借鉴。
