核磁共振測油儀/核(he)磁(ci)共(gong)(gong)振(zhen)含(han)油量(liang)(liang)測(ce)量(liang)(liang)儀是利(li)用核(he)磁(ci)共(gong)(gong)振(zhen)技術，直接測(ce)量(liang)(liang)樣(yang)(yang)(yang)品中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)液(ye)態(tai)(tai)氫(qing)(qing)核(he)的(de)(de)(de)含(han)量(liang)(liang)來推算樣(yang)(yang)(yang)品中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)含(han)油率。在(zai)(zai)(zai)一(yi)定的(de)(de)(de)恒定磁(ci)場和射頻交變(bian)磁(ci)場的(de)(de)(de)照射下，物(wu)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)氫(qing)(qing)核(he)的(de)(de)(de)能(neng)(neng)(neng)級(ji)分裂成(cheng)二種(zhong)狀(zhuang)態(tai)(tai)，低(di)能(neng)(neng)(neng)態(tai)(tai)和高能(neng)(neng)(neng)態(tai)(tai)。低(di)能(neng)(neng)(neng)態(tai)(tai)的(de)(de)(de)核(he)在(zai)(zai)(zai)條件(jian)得到滿(man)足時(shi)，吸收射頻場中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)能(neng)(neng)(neng)量(liang)(liang)可躍(yue)(yue)遷(qian)到高能(neng)(neng)(neng)狀(zhuang)態(tai)(tai)，當條件(jian)不滿(man)足時(shi)，它們(men)又返回低(di)能(neng)(neng)(neng)狀(zhuang)態(tai)(tai)。只要我們(men)控制(zhi)滿(man)足氫(qing)(qing)核(he)躍(yue)(yue)遷(qian)的(de)(de)(de)條件(jian)，就(jiu)可控制(zhi)躍(yue)(yue)遷(qian)的(de)(de)(de)發生(sheng)(sheng)。一(yi)般當有躍(yue)(yue)遷(qian)發生(sheng)(sheng)時(shi)，我們(men)就(jiu)稱之(zhi)為發生(sheng)(sheng)了(le)共(gong)(gong)振(zhen)。我們(men)只要將躍(yue)(yue)遷(qian)到高能(neng)(neng)(neng)狀(zhuang)態(tai)(tai)的(de)(de)(de)氫(qing)(qing)核(he)的(de)(de)(de)數目測(ce)量(liang)(liang)出(chu)(chu)來，就(jiu)能(neng)(neng)(neng)測(ce)量(liang)(liang)出(chu)(chu)樣(yang)(yang)(yang)品中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)氫(qing)(qing)核(he)的(de)(de)(de)含(han)量(liang)(liang)。通常被測(ce)樣(yang)(yang)(yang)品中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)氫(qing)(qing)核(he)存在(zai)(zai)(zai)于(yu)液(ye)態(tai)(tai)物(wu)體(ti)(ti)和固(gu)態(tai)(tai)物(wu)體(ti)(ti)之(zhi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)，由于(yu)固(gu)態(tai)(tai)物(wu)體(ti)(ti)和液(ye)態(tai)(tai)物(wu)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)氫(qing)(qing)核(he)參與共(gong)(gong)振(zhen)的(de)(de)(de)外(wai)界(jie)(jie)條件(jian)不一(yi)樣(yang)(yang)(yang)。液(ye)態(tai)(tai)物(wu)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)氫(qing)(qing)核(he)在(zai)(zai)(zai)外(wai)界(jie)(jie)磁(ci)場變(bian) 化很(hen)小范(fan)圍時(shi)（約 10-5T ）就(jiu)全部參與共(gong)(gong)振(zhen)， 而(er)同(tong)一(yi)樣(yang)(yang)(yang)品固(gu)態(tai)(tai)物(wu)體(ti)(ti)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)氫(qing)(qing)核(he)要 在(zai)(zai)(zai)外(wai)界(jie)(jie)磁(ci)場變(bian)化很(hen)大時(shi)（約 10-3T ），才全部參與共(gong)(gong)振(zhen)，利(li)用這一(yi) 特點(dian)在(zai)(zai)(zai)儀器之(zhi)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)設置一(yi)個電子開關，讓(rang)液(ye)態(tai)(tai)中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)共(gong)(gong)振(zhen)信號(hao)通過，而(er)將固(gu)態(tai)(tai)物(wu)體(ti)(ti) 中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)的(de)(de)(de)信號(hao)切除掉(diao)，這樣(yang)(yang)(yang)便能(neng)(neng)(neng)將代(dai)表含(han)油量(liang)(liang)的(de)(de)(de)液(ye)態(tai)(tai)共(gong)(gong)振(zhen)信號(hao)選擇出(chu)(chu)來。根據信號(hao) 的(de)(de)(de)大小，可推算出(chu)(chu)樣(yang)(yang)(yang)品中(zhong)(zhong)(zhong)(zhong)(zhong)(zhong)液(ye)態(tai)(tai)物(wu)體(ti)(ti)氫(qing)(qing)核(he)的(de)(de)(de)含(han)量(liang)(liang)，從而(er)測(ce)量(liang)(liang)出(chu)(chu)含(han)油率。
