而且可以大大意外事故損失，其主要功能有：●及時性。油田后方能夠?qū)崟r每個區(qū)域、甚至每口油、氣井的生產(chǎn)動態(tài)，為快速制定生產(chǎn)和經(jīng)營方案提供決策依據(jù)。●自動。在出現(xiàn)意外情況，如輸油管線破裂，造成主管流量和分支管線流量之和產(chǎn)生較大差異，計算機(jī)經(jīng)運(yùn)算發(fā)出，提醒用戶及時采取措施，事故損失。●在局部區(qū)域，如一個采油站或聯(lián)合站內(nèi)，出現(xiàn)異常情況，如某管線壓力嚴(yán)重下降，可自動關(guān)閉相關(guān)閥門，防止事故發(fā)生。●統(tǒng)計數(shù)據(jù)的準(zhǔn)確性。本提供各種形式的自動報表，不但節(jié)約大量人力，也了因人為因素造成的誤差。●量小。由于采用了無線通訊技術(shù)，野外沒有通訊線路，可大大量。●在采油站、聯(lián)合站也可監(jiān)控每口井或每個采油站的生產(chǎn)情況。 3、壓力使用，在實(shí)際需要的壓力段運(yùn)行，據(jù)統(tǒng)計每下降1公斤壓力可節(jié)能大約7%的能耗。
