Experimental research on the detection of aromatic hydrocarbons for soil samples of oil and gas geochemical exploration by rapid solvent extraction and fluorescence detection

Through optimizing the detecting conditions of the aromatic hydrocarbon for soil samples, such as the blank experiment, sample weight, extraction temperature and extraction pressure, the authors obtained the best analysis conditions. According to the ex-perimental results,the method has been established.Methodological indicators such as repeatability has been used to evaluate the meth-od. Compared with the conventional extraction effect,the extraction rate of rapid solvent extraction has been increased. In a known geo-logical section south of Nanyang sag,North Ma Zhuang area,the application effect of rapid solvent extraction with fluorescence method was carried out. The results show that this method can describe the regional geochemical anomalies.
