摘　　要：烃源岩包括油源岩、气源岩和油气源岩,习惯上通常叫作生油岩,它是一种能够产生或已经产生可移动烃类的岩石。烃源岩含有大量有机质即干酪根。红外碳硫分析仪是根据不同物质对红外光谱的吸收有其特定波长的特性及朗伯比尔定律而设计的。烃源岩在高温炉内于氧气流中燃烧,样品中的硫全部转化为二氧化硫气体,红外线被二氧化硫气体特性波长所吸收,根据红外线吸收前后的能量之差与二氧化硫浓度间关系,由固态检测器,前置放大器以及A/D转换送到终端,得出干酪根硫含量。Source rocks include oil source rocks, gas source rocks and oil and gas source rocks. They are commonly called source rocks. They are rocks that can produce or have produced movable hydrocarbons. Source rocks contain a large amount of organic matter, also known as namely kerogen. Infrared Carbon and Sulphur Meter is designed according to the absorption of infrared spectra by different substances with their specific wavelength characteristics and Lambert’s law.Source rocks burn with oxygen flow in tube, sulfur in the sample is converted into sulfur dioxide, infrared light is absorbed by characteristic wavelength of sulfur dioxide, the relationship between the energy difference before and after infrared absorption and the concentration of sulfur dioxide, calculat kerogen sulfur content by solid state detector、preamplifier and A/D converter.
