    總而言之，油氣田工作環境中的儀表係統故障特征

，可以基於儀表自身屬性劃分為如下四個主要方麵。
2.1溫度控製儀表係統故障分析
    對於溫度控製儀表而言

，通常多采用電動儀表實現測量、指zhi示shi以yi及ji控kong製zhi，並bing且qie此ci類lei儀yi表biao的de測ce量liang通tong常chang表biao現xian出chu較jiao為wei明ming顯xian的de時shi間jian滯zhi後hou特te征zheng。對dui於yu這zhe儀yi表biao而er言yan
，如ru果guo其qi示shi值zhi突tu然ran表biao示shi為wei極ji值zhi，或huo者zhe出chu現xian陡dou然ran波bo動dong
，都dou表biao示shi著zhe儀yi表biao可ke能neng發fa生sheng故gu障zhang。因yin為wei，對dui於yu石shi油you氣qi田tian生sheng產chan工gong作zuo環huan境jing而er言yan，通tong常chang的de溫wen度du都dou會hui保bao持chi相xiang對dui的de穩wen定ding。對dui於yu突tu然ran指zhi示shi極ji值zhi的de儀yi表biao
，應ying當dang長chang點dian考kao慮lv是shi否fou存cun在zai有you熱電偶，熱電阻，補償導線斷線或變送器放大器失靈等故障狀況發生
；而er對dui於yu示shi值zhi較jiao大da幅fu度du波bo動dong或huo者zhe快kuai速su震zhen蕩dang情qing況kuang，則ze應ying當dang在zai相xiang關guan參can數shu設she置zhi以yi及ji人ren員yuan操cao作zuo確que認ren無wu誤wu的de基ji礎chu之zhi上shang
，重zhong點dian考kao慮lv儀yi表biao控kong製zhi係xi統tong本ben身shen是shi否fou出chu現xian故gu障zhang。

，以及在控製器測量指示係統是否健康。
2.3流量控製儀表係統故障分析
    流(liu)量(liang)控(kong)製(zhi)儀(yi)表(biao)對(dui)於(yu)石(shi)油(you)天(tian)然(ran)氣(qi)工(gong)業(ye)環(huan)境(jing)而(er)言(yan)相(xiang)對(dui)重(zhong)要(yao)，相(xiang)關(guan)故(gu)障(zhang)情(qing)況(kuang)也(ye)相(xiang)對(dui)複(fu)雜(za)。當(dang)流(liu)量(liang)控(kong)製(zhi)儀(yi)表(biao)係(xi)統(tong)指(zhi)示(shi)值(zhi)達(da)到(dao)最(zui)小(xiao)時(shi)，首(shou)先(xian)需(xu)要(yao)展(zhan)開(kai)對(dui)於(yu)現(xian)場(chang)檢(jian)測(ce)儀(yi)表(biao)的(de)確(que)認(ren)，並(bing)且(qie)通(tong)過(guo)檢(jian)查(zha)調(tiao)節(jie)閥(fa)開(kai)度(du)來(lai)確(que)定(ding)故(gu)障(zhang)所(suo)在(zai)位(wei)置(zhi)。如(ru)果(guo)現(xian)場(chang)檢(jian)測(ce)儀(yi)表(biao)指(zhi)示(shi)同(tong)樣(yang)最(zui)小(xiao)

、係統管路堵塞、泵不上量、介質結晶、造作不當等環節中。如果故障存在於儀表方麵
，則需要考察孔板差壓流量計shifoucunzaichilunkasidengwenti。erdangliuliangkongzhiyibiaohejianceyibiaojunshizhizuidadeshihou，keyishoudongkongzhitiaojiefalaitongguoliuliangbianhuaquedingguzhangshifouyuanyugongyicaozuo。
2.4液位控製儀表係統故障分析
    液ye位wei控kong製zhi儀yi表biao係xi統tong故gu障zhang的de時shi候hou，首shou先xian應ying當dang檢jian查zha檢jian測ce儀yi表biao狀zhuang況kuang，當dang檢jian測ce儀yi表biao正zheng常chang的de時shi候hou，可ke以yi更geng改gai為wei手shou動dong控kong製zhi來lai查zha看kan狀zhuang況kuang。如ru果guo手shou動dong控kong製zhi仍reng然ran無wu法fa穩wen定ding液ye位wei，則ze應ying當dang確que認ren為wei工gong藝yi故gu障zhang。當dang液ye位wei控kong製zhi係xi統tong和he現xian場chang隻zhi讀du式shi指zhi示shi儀yi表biao不bu一yi致zhi的de時shi候hou，需xu要yao在zai確que認ren現xian場chang儀yi表biao正zheng常chang的de前qian提ti下xia對dui差cha壓ya式shi液ye位wei儀yi表biao的de負fu壓ya導dao壓ya管guan封feng液ye進jin行xing檢jian查zha
，確que保bao不bu存cun在zai的de滲shen漏lou，並bing且qie依yi據ju實shi際ji情qing況kuang對dui儀yi表biao的de負fu遷qian移yi量liang進jin行xing確que認ren和he糾jiu正zheng。而er對dui於yu液ye位wei控kong製zhi儀yi表biao係xi統tong示shi值zhi波bo動dong嚴yan重zhong的de時shi候hou，則ze需xu要yao先xian分fen析xi液ye麵mian控kong製zhi對dui象xiang容rong量liang大da小xiao，並bing且qie區qu分fen對dui待dai究jiu竟jing是shi儀yi表biao故gu障zhang還hai是shi工gong藝yi引yin發fa。
