摘要
酸解烃是石油及天然气地球化学勘查中极为重要的指标。黄土样品经过热处理后酸解烃含量显著增加．通过油气区和非油气区黄土热处理酸解烃对比研究得出热处理酸解烃对油气地球化学勘查无意义。经过黄土的矿物成分、地球化学实验和酸解烃甲烷碳同位素分析得出热处理增加的烃类来自于碳酸盐矿物中有机物的热解，正常状态条件下酸解烃分析对地球化学勘查有意义。
Adsorbed hydrocarbon is a very important indicator in geochemical exploration for oil and gas. By thermal treatment,the concentration of a adsorbed hydrocarbon in loess increases rapidly.Thermaltreatment adsorbed hydrocarbon is insignificant to geochemical exploration for oil and gas through the contrast studying of thermal treatment adsorbed hydrocarbon in loess from oil and gas fields and non-oil and gas regions The increasing hydrocarbons come from separation of organic matters in carbonates and adsorbeda hydrocarbon in normal condition is useful to geochemical exploration for oil and gas by researching of mineral compositions,geochemical experiment and methane carbon isotope in loess.
