I-oyile yoKwemba iBanga le-CMC LV

I-oil drilling grade carboxymethyl cellulose (CMC) LV luhlobo lwepolymer enyibilikayo emanzini esetyenziswa kakhulu kwishishini leoli kunye negesi. Yimveliso eguqulweyo ye-cellulose, i-compound yendalo efumaneka kwiindonga zeeseli zezityalo. I-CMC LV iqhele ukusetyenziswa njenge-viscosifier, i-rheology modifier, isinciphisi sokulahlekelwa kwamanzi, kunye ne-shale inhibitor kwi-drilling fluids. Kweli nqaku, siza kuxoxa ngeepropati, izicelo, kunye nezibonelelo ze-oyile yokomba ibakala CMC LV.

Iipropati ze-CMC LV

I-oyile yokomba ibakala CMC LV ngumgubo omhlophe okanye ongekho-mhlophe, ongenavumba, kunye nomgubo ongenancasa onyibilika kakhulu emanzini. Ithathwe kwi-cellulose ngokusebenzisa inkqubo yokuguqulwa kweekhemikhali ebandakanya ukongezwa kwamaqela e-carboxymethyl kwi-molecule ye-cellulose. Iqondo lokuthatha indawo (DS) limisela inani lamaqela e-carboxymethyl ngeyunithi ye-glucose kwi-molecule ye-cellulose, echaphazela iipropati ze-CMC LV.

I-CMC LV ineempawu ezininzi ezenza kube luncedo kulwelo lokomba. Yipolymer enyibilikayo emanzini enokuthi yenze izisombululo ze-viscous ngamanzi. Ikwanovakalelo nge-pH, kunye ne-viscosity yayo iyancipha njengoko i-pH inyuka. Le propati ivumela ukuba isetyenziswe kwiindawo ezininzi ze-pH. Ukongeza, i-CMC LV inokunyamezela ityuwa ephezulu, eyenza ilungele ukusetyenziswa kwi-brine-based drilling fluids.

Usetyenziso lwe-CMC LV

I-Viscosifier
Esinye sezicelo eziphambili ze-CMC LV kulwelo lokomba lunjenge-viscosifier. Inokunceda ukunyusa i-viscosity ye-drilling fluid, enceda ukumisa kunye nokuthutha i-drill cuttings ukuya phezulu. Le propati ibaluleke kakhulu kwimisebenzi yokugaya apho ukubunjwa kwe-drilled kungazinzi okanye apho kukho umngcipheko wokulahleka kokujikeleza.

Isilungisi seRheology
I-CMC LV ikwasetyenziswa njenge-rheology modifier kwi-drilling fluids. Inokukunceda ukulawula iimpawu zokuhamba kwamanzi, okubaluleke kakhulu ukugcina uzinzo lwequla. I-CMC LV inokunceda ukunqanda ukudilika okanye ukuhlalisa izinto eziqinileyo kulwelo lokomba, nto leyo enokukhokelela kwiingxaki zokomba.

I-Fluid Loss Reducer
I-CMC LV ikwasetyenziswa njengesinciphisi ilahleko yolwelo kulwelo lokomba. Inganceda ukwenza ikeyiki ecekethekileyo, engenamanzi yokucoca eludongeni lomthombo, onceda ekunciphiseni ilahleko yolwelo lokomba ekubunjweni kwayo. Le propati ibaluleke kakhulu ekubunjweni kunye nokunyanzeliswa okuphantsi okanye kwimisebenzi enzulu yokugaya apho iindleko zokujikeleza ezilahlekileyo zingabaluleka.

I-Shale Inhibitor
I-CMC LV ikwasetyenziswa njenge-shale inhibitor kwi-drilling fluids. Inganceda ukuthintela ukudumba kunye nokusasazwa kokwakheka kwe-shale, okunokukhokelela ekungazinzini kwequla kunye nokulahleka kokujikeleza. Le propati ibaluleke kakhulu kwimisebenzi yokugaya apho ukubunjwa okwenziwa yi-shale.

Izibonelelo zeCMC LV

Uphuculo lokuSebenza ngokuSebenzayo
I-CMC LV inokunceda ekuphuculeni ukusebenza kakuhle kokugrumba ngokunciphisa umngcipheko wokujikeleza okulahlekileyo, ukugcina uzinzo lwe-wellbore, kunye nokuphucula iimpawu zolwelo lokomba. Le propati inokunceda ukunciphisa iindleko zokugaya kunye nokuphucula ukusebenza ngokubanzi komsebenzi wokugaya.

Ukuphuculwa kozinzo lweWellbore
I-CMC LV inokunceda ekuphuculeni uzinzo lwe-wellbore ngokulawula iimpawu zokuqukuqela kolwelo lokomba kunye nokuthintela ukudumba nokusasazwa kokwakheka kwe-shale. Lo mhlaba unokunceda ukunciphisa umngcipheko wokuwa kwequla okanye ukuvuthuza kwamanzi, okunokuba yindleko kwaye kuyingozi.

UkuNcitshiswa kweMpembelelo yokuSingqongileyo
I-CMC LV yimathiriyeli enokubola kwaye ilungele ukusingqongileyo engenazo naziphi na iziphumo eziyingozi kokusingqongileyo. Le propati iyenza ibe yindlela ekhangayo kwimisebenzi yokomba kwiindawo ezinobume bendalo.

Isebenza kakuhle emalini
I-CMC LV lukhetho olungabizi kakhulu kwiincindi zokomba xa kuthelekiswa nezinye iipholima zokwenziwa kunye nezongezo. Ifumaneka ngokulula kwaye inexabiso eliphantsi xa kuthelekiswa nezinye iipolymers zokwenziwa kunye nezongezo, nto leyo eyenza kube yinto enomtsalane kwimisebenzi emininzi yokomba.

Ukuguquguquka
I-CMC LV yipolymer eguquguqukayo enokusetyenziswa kuluhlu olubanzi lolwelo lokomba. Ingasetyenziswa kumanzi amatsha asekelwe kumanzi, ityuwa esekwe kwityuwa, kunye nolwelo olusekwe kwi-oyile. Oku kuguquguquka kwenza ukuba ibe yipolymer eyaziwayo kwishishini leoli kunye negesi.

Ukuqukumbela

I-oyile yokomba i-carboxymethyl cellulose (CMC) LV yipolymer eguquguqukayo kwaye isetyenziswa ngokubanzi kwishishini leoli kunye negesi.
