摘　　要：地表介质中存在的烃类除了包裹于碳酸盐矿物中（酸解烃法测量）外，还吸留于粘土等硅酸盐矿物中。本文介绍的热释烃技术，通过在中低温度下热脱的方法解吸硅酸盐矿物中吸留的烃类。方法快速经济，在陕北黄土塬地区，河南酸性土壤地区等特殊地质景观地区应用，取得令人满意的化探效果，是油气勘探中值得推广的一种新的技术方法。Besides included within carbonate mineral (determined by the acidolysis desorbed hydrocarbon method), hydrocarbons existing in surface medium are also occluded in clay and other silicate mineral. The pyrolysis desorbed hydrocarbon technology introduced in this paper makes this part of hydrocarbons desorbed under low and middle temperature. This method is fast and economical, and has brought about satisfactory results for geochemical exploration when applied in the loesslands of North Shaanxi province, the acid soil areas of Henan province and other special geologic landscape areas. It is a new technology worth spreading in gas and oil exploration.
