Abstract

A method is proposed to target-screen the eight organic chloride compounds in chemical agents of liquid oil fields using gas chromatography and mass spectrometry(GC/MS). Parameters affecting both extraction and instrumental analysis are studied. Under optimal conditions, the linear range is from 2 to 100 ng/μL for the target compounds. The correlation coefficient R is above 0.99 for the analytes with the 1imit of detection(LOD) ranging from 10 to 120 ng/mL. Good recovery, ranging from 77.2% to 93.5% with relative standard deviation (RSD) less than 7%, has been achieved in the matric spiking experiments. The established method is applied to target-screen the eight organic chloride compounds in a mixed sample of chemical agents of liquid oil fields provided by the Shengli Oilfield Corporation. However, no target compound is detected in the sample. Reasons for such result are given in the paper.

Key words： oil field chemical agent; organic chloride compound;  target-screening; gas chromatography and mass spectrometry
