Yeyiphi imisebenzi yePetroleum Oli Yokomba iBanga le-CMC?

Ibakala lokomba ioyile yePetroleum iCarboxymethyl Cellulose (CMC) isebenza kwimisebenzi emininzi ebalulekileyo kwinkqubo yokomba yeoli. Nantsi imisebenzi yayo ephambili:

1. Isilungisi seViscosity:

I-CMC isetyenziswa njenge-viscosity modifier kwi-drilling fluids ukulawula iimpawu ze-rheological zolwelo. Ngokulungelelanisa i-concentration ye-CMC, i-viscosity ye-drilling fluid inokulungelelaniswa ukuhlangabezana neemfuno ezithile zomsebenzi wokugaya. Ulawulo olululo lwe-viscosity lubalulekile ekugcineni uzinzo lwe-hydraulic, ukuthintela ukulahleka kolwelo, kunye nokuthwala i-drill cuttings ukuya phezulu.

2. Ulawulo lwelahleko yolwelo:

I-CMC yenza ikeyiki ecekethekileyo, engangenekiyo yokucoca kudonga lomngxuma, enceda ekulawuleni ilahleko yolwelo ekubunjweni kwayo ngexesha lokomba. Le keyiki yokucoca isebenza njengomqobo, ukunciphisa umngcipheko wokungazinzi kwe-wellbore, umonakalo wokwakheka, kunye nokulahleka kokujikeleza. I-CMC itywina ngokufanelekileyo ukwakheka kunye nokwaphuka, iqinisekisa ukusebenza ngokufanelekileyo kokomba.

3. Ukunqunyanyiswa kunye nokuThintelwa kweShale:

I-CMC inceda ukunqumamisa nokuthwala i-drill cuttings kunye namanye amasuntswana aqinileyo ukuya kumphezulu, ukuthintela ukuhla kwazo kunye nokuqokelelana ezantsi kwequla. Ikwanqanda i-hydration kunye nokusasazwa kokubunjwa kwe-shale, ukunciphisa umngcipheko wombhobho oxinyiweyo, ukungazinzi kwe-wellbore, kunye nomonakalo wokwakheka. I-CMC iphucula ukusebenza kakuhle kunye nokhuseleko lwemisebenzi yokomba ngokugcina imfezeko ye-wellbore kunye nokunciphisa ixesha lokuphumla.

4. Ukuthambisa kunye nokuNcitshiswa kweFriction:

I-CMC isebenza njengesithambisi kulwelo lokomba, inciphisa ukukhuhlana phakathi komtya wokugrumba kunye nodonga lomngxuma. Oku kunciphisa i-torque kunye ne-drag kwi-drill string, ukuphucula ukusebenza kakuhle kunye nokunciphisa ukunxiba kunye nokukrazula kwizixhobo zokomba. I-CMC ikwaphucula ukusebenza kweenjini zomhombiso kunye nezixhobo zokomba ezijikelezayo ngokunciphisa ukukhuhlana kunye nokuveliswa kobushushu.

5. Iqondo lobushushu kunye nokuzinza kwetyuwa:

I-CMC ibonisa ubushushu obubalaseleyo kunye nokuzinza kwetyuwa, iyenza ilungele ukusetyenziswa kwiindawo ezininzi zokomba, kubandakanywa ubushushu obuphezulu kunye neemeko zetyuwa eninzi. Igcina iipropati zayo ze-rheological kunye nezakhono zokulawula ilahleko ye-fluid naphantsi kweemeko ze-downhole ezigqithisileyo, iqinisekisa ukusebenza okungaguqukiyo kunye nokuthembeka kwimisebenzi ecela umngeni.

6. Ayihambelani nendalo:

I-CMC ihambelana nokusingqongileyo kwaye iyakwazi ukubola, iyenze ilungele ukusetyenziswa kwiindawo zokomba ezinobuthathaka kokusingqongileyo. Ayiqukethe izongezo ezinobungozi okanye iikhemikhali ezinobuthi, ukunciphisa impembelelo kwindawo engqongileyo kunye nemithombo yamanzi aphantsi komhlaba. Ulwelo lokomba olusekwe kwi-CMC luthobela imimiselo nemigangatho yokusingqongileyo, ukuqinisekisa izenzo zokomba ezizinzileyo.

Isishwankathelo, ibakala lokomba i-oyile yepetroleum iCarboxymethyl Cellulose (CMC) isebenza imisebenzi emininzi ebalulekileyo kulwelo lokomba, kubandakanywa ukuguqulwa kwe-viscosity, ukulawulwa kwelahleko yolwelo, ukunqunyanyiswa kunye nokuthintelwa kwe-shale, ukuthambisa kunye nokunciphisa ukungqubana, ubushushu kunye nokuzinza kwetyuwa, kunye nobuhlobo bendalo. Iipropati zayo eziguquguqukayo zinegalelo ekusebenzeni kakuhle, ukhuseleko, kunye nokuzinza kwe-oyile kunye nokusebenza kwegesi yokomba kwihlabathi jikelele.
