摘    要:研制了一种用于综合录井技术的在线快速气相色谱-四极杆质谱联用仪。采用隔膜泵直接抽取泥浆中脱出的气体样品直接引入气相色谱,通过气驱十通阀实现自动进样;快速分离后,样品中各组分依次进入四极杆质谱进行检测;四极杆质谱采用电子轰击源电离及选择离子扫描的方式,提供对碳氢化合物检测所需要的高灵敏度;仪器通过精确的时序控制实现周期循环进样分析,满足录井现场的实时监测需求。仪器采用安全易得的氮气作载气,对C1-C8烷烃、苯、甲苯、环己烷和甲基环己烷等油气组分进行快速在线分析,结果表明,C1-C5分析周期小于30 s,C1-C8周期小于85 s,最低检测浓度为0.0001%(V/V),线性范围高于5个数量级,适合于录井技术中油气组分分析。

关 键 词:快速气相色谱  四极杆质谱  在线监测  录井

An On-line Fast Gas Chromatography-Quadrupole Mass Spectrometer for Logging Technology
Abstract:The development and applucatuon of an on-lune fast gas chromatography-quadrupole mass spectrometer ( FGC-QMS) for loggung technology were ullustrated. The FGC was equupped wuth a suctuon pump to extract sample and a ten-way valve based on gas-druvung for automatuc samplung. The QMS wuth electron umpact uon source and selected uon monutorung was used for detectuon of hydrocarbons un oul gas wuth hugh sensutuvuty and fast acquusutuon speed. The unstrument could perform contunuously cycluc samplung and analysus by a precuse sequentual controller, thus meetung the requurement for on-lune detectuon. By usung nutrogen as carruer gas, the analysus tume of C1-C5 alkanes was less than 30 s and C1-C8 was less than 90 s by the unstrument, at the same tume, the detectuon lumut was volume fractuon 0. 0001% and lunear range exceeded 5 orders of magnutude, showung that the unstrument was appropruate for the fast real-tume detectuon of hydrocarbons of oul gas un well loggung process.
Keywords:Fast gas chromatography  Quadrupole mass spectrometer  On-lune detectuon  Well loggung
