摘　　要：试验采用气相色谱法定量分析探井采出原油中油基泥浆的污染量,选择相邻的色谱峰,根据色谱峰变化规律计算峰型变化校正系数,确定污染的色谱峰的实际峰面积,根据峰面积的增量利用外标法对污染物进行定量分析,并在无污染原油中定量加入污染物,验证该方法的适用性。结果表明,整体偏差在2%以内,该方法简捷可靠,能准确定量污染原油样品中油基泥浆的污染量,满足实际生产需求。In this experiment,gas chromatography is used to quantitatively analyze the pollution level of oil-based mud in crude oil extracted from exploration wells,and adjacent chromatographic peaks are selected,and the peak shape correction coefficient is calculated based on the peak variation pattern to determine the actual peak area of the contaminated chromatographic peak,based on the increment of peak area,the external standard method is used for quantitative analysis of pollutants,and the pollutants are quantitatively added to unpolluted crude oil to verify the applicability of this method.The results indicate that the overall deviation is within 2%,and this method is simple and reliable,and can accurately quantify the amount of oil-based mud contamination in crude oil samples,meeting practical production needs.
