1、中文摘要三次采油是勝利油田的主要采油工藝之一,而昂貴的高溫高壓注汽管網(wǎng)又是三采中的主要設(shè)備。注汽管網(wǎng)的被盜被毀,一直是油田感到困擾的問(wèn)題,它不僅造成油田財(cái)產(chǎn)的重大損失,而且影響了注汽計(jì)劃的按時(shí)完成,破壞了正常生產(chǎn)秩序。本文針對(duì)勝利油田某采油廠的具體地理位置,在多次的現(xiàn)場(chǎng)調(diào)研、細(xì)致的方案設(shè)計(jì)、深入的實(shí)驗(yàn)室試驗(yàn),以及完成軟件開(kāi)發(fā)、數(shù)據(jù)庫(kù)等大量工作的基礎(chǔ)上,設(shè)計(jì)、研制了“注汽管網(wǎng)自動(dòng)監(jiān)測(cè)系統(tǒng)”。它能夠及時(shí)、準(zhǔn)確地對(duì)盜竊不法活動(dòng)進(jìn)行報(bào)警記錄,通知巡邏隊(duì)處理。本文內(nèi)容包括系統(tǒng)設(shè)計(jì)、軟件開(kāi)發(fā)兩部分。在設(shè)計(jì)郝分,綜合運(yùn)用傳感器、信號(hào)處理、單片機(jī)、無(wú)線通信、計(jì)算機(jī)等知識(shí),設(shè)計(jì)出完整的自動(dòng)監(jiān)測(cè)系
2、統(tǒng)方案。特別對(duì)無(wú)線傳輸中天線高度、線路衰減,及多站通信降低誤碼途徑,進(jìn)行了理論計(jì)算;對(duì)電子器件的耐低溫及極端高溫、全天候應(yīng)用提出了解決方案,進(jìn)行了試驗(yàn);這些工作為自動(dòng)監(jiān)測(cè)系統(tǒng)的實(shí)現(xiàn)奠定了基礎(chǔ)。在軟件開(kāi)發(fā)部分,研制了具有數(shù)據(jù)庫(kù)、分層次管理、電子地圖動(dòng)態(tài)標(biāo)示等功能的自動(dòng)監(jiān)測(cè)軟件。自動(dòng)監(jiān)測(cè)系統(tǒng)用于高溫高壓注汽管網(wǎng)監(jiān)測(cè),整體設(shè)計(jì)尚屬首次。經(jīng)過(guò)四個(gè)月的運(yùn)行,表明該系統(tǒng)工作可靠、識(shí)別準(zhǔn)確、實(shí)時(shí)性強(qiáng)、監(jiān)測(cè)距離遠(yuǎn)、隱蔽性高、入機(jī)界面友好,已通過(guò)采油廠驗(yàn)收。關(guān)鍵詞注汽管網(wǎng)防盜竊監(jiān)測(cè)系統(tǒng)特征識(shí)別無(wú)線通信全天候儀器ASupervisionSystemofSteamInjectionPipelines
