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 eziyingozi 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 ioyile yepetroleum iCarboxymethyl Cellulose (CMC) isebenza imisebenzi emininzi ebalulekileyo kulwelo lokomba, kubandakanywa ukuguqulwa kwe-viscosity, ukulawulwa kokulahleka kolwelo, ukunqunyanyiswa kunye nokuthintelwa kwe-shale, ukuthambisa kunye nokunciphisa ukungqubana, ubushushu kunye nokuzinza kwetyuwa, kunye nobuhlobo bendalo.Iipropathi zayo eziguquguqukayo zinegalelo ekusebenzeni kakuhle, ukhuseleko, kunye nokuzinza kweoyile kunye nokusebenza kwegesi yokomba kwihlabathi liphela.
