【摘要】：隨著淺層石油資源的日益枯竭和井況的日趨惡劣,潛油電泵以其高效率、大排量、高揚(yáng)程等優(yōu)點(diǎn)實(shí)現(xiàn)了石油開采中后期的順利進(jìn)行,成為了井液人工舉升的重要裝備。在石油開采技術(shù)不斷進(jìn)步的趨勢下,井深不斷增加,井溫隨之上升,針對(duì)高溫井下環(huán)境的多參數(shù)監(jiān)測技術(shù)研究對(duì)深井、高溫井采油系統(tǒng)的運(yùn)行監(jiān)視、故障預(yù)測、泵效率提高和采油方案優(yōu)化均具有重要意義。本文針對(duì)150℃潛油電泵油井的井下多參數(shù)監(jiān)測技術(shù)進(jìn)行深入研究。通過對(duì)井下高溫供電、單片機(jī)時(shí)序控制、電流環(huán)信號(hào)傳輸、地面遠(yuǎn)程電源和數(shù)據(jù)采樣處理等關(guān)鍵技術(shù)的研究,實(shí)現(xiàn)對(duì)潛油電泵油井的泵入口溫度、泵入口壓力、泵出口壓力、電機(jī)繞組溫度、X軸方向振動(dòng)、Y軸方向振動(dòng)和泄漏電流七個(gè)物理量的實(shí)時(shí)監(jiān)測。監(jiān)測系統(tǒng)可按照功能和結(jié)構(gòu)劃分為井下參數(shù)測量單元和地面二次儀表兩部分。井下參數(shù)測量單元完成高溫環(huán)境下的參數(shù)測量和傳輸工作。采用基于高溫磁芯材料的反激式電路實(shí)現(xiàn)井下參數(shù)測量電路和單片機(jī)的供電,利用高溫傳感器和低功耗設(shè)計(jì)的調(diào)理電路對(duì)井下參數(shù)進(jìn)行測量,通過帶多路A/D功能的高溫單片機(jī)實(shí)現(xiàn)各參數(shù)的分時(shí)采樣和傳輸,時(shí)序信號(hào)通過電壓-電流轉(zhuǎn)換電路轉(zhuǎn)換成電流信號(hào)后,通過電流環(huán)傳輸至地面二次儀表。地面儀表可分為三個(gè)部分:遠(yuǎn)程供電電源、基于ARM7的主控電路板和MCGS觸摸屏。通過基于TOP264EG芯片的反激式開關(guān)電源實(shí)現(xiàn)AC/DC變換,再將其直流輸出接到地面電抗器星點(diǎn)處,實(shí)現(xiàn)地面儀表的遠(yuǎn)程無纜供電。主控電路板利用電流-電壓轉(zhuǎn)換電路獲取井下測量信號(hào),再經(jīng)過A/D轉(zhuǎn)換后送ARM7芯片進(jìn)行數(shù)字濾波。同時(shí)主控板還實(shí)現(xiàn)了周期性供電控制、數(shù)據(jù)送顯、繼電保護(hù)和歷史數(shù)據(jù)存儲(chǔ)等功能。通過對(duì)MCGS觸摸屏的界面設(shè)計(jì),實(shí)現(xiàn)運(yùn)行監(jiān)視、參數(shù)曲線、報(bào)警保護(hù)值設(shè)定等功能。對(duì)系統(tǒng)進(jìn)行軟硬件設(shè)計(jì)后,通過實(shí)驗(yàn)對(duì)系統(tǒng)各方面性能進(jìn)行測試。實(shí)驗(yàn)表明井下參數(shù)測量單元在150℃及以下的環(huán)境溫度中均可正常工作,地面二次儀表能夠?qū)崿F(xiàn)對(duì)井下測量信號(hào)的獲取、采樣和顯示功能,整體系統(tǒng)的參數(shù)測量精度滿足性能指標(biāo),并且具有良好的穩(wěn)定性。

It has become an important equipment for the artificial lifting of well fluid. With the development of oil production technology, the depth of wells increases and the temperature of wells rises. The multi-parameter monitoring technology for high temperature downhole environment is studied on the deep wells. Operation monitoring and fault prediction of oil recovery system in high temperature wells. The improvement of pump efficiency and the optimization of oil recovery scheme are of great significance.
