Ukusetshenziswa okuthize kwe-CMC ekuvuthayo kawoyela

I-CMC (i-carboxymethyl celtuleose) isetshenziswa kabanzi ekubizeni uwoyela, ikakhulukazi ku-drive fluids, uketshezi lokuqedelwa kokuqedwa kanye nokuncipha kokonga.

1. Isicelo ku-Drilling Fluid
Ukushayela uketshezi kuyinto ebalulekile kwinqubo yokumba kawoyela, kanye ne-CMC, njenge-drive fluid fluid engezansi, kungathuthukisa kakhulu ukusebenza koketshezi lokumba. Imisebenzi yayo eqondile imi ngalendlela elandelayo:

1.1 Yehlisa ukulahleka kwamanzi
I-CMC ingukunciphisa imfucumfucu elahlekelwe yi-fluid ehle kakhulu engakha ikhekhe eliminyene eliku-fluid evuthayo, ukunciphisa ngokuphumelelayo ukulahleka kwamanzi koketshezi lokumba nokuvikela ukuqina kodonga kahle. Lokhu kubalulekile ukuvimbela ukuwa kodonga kahle futhi uvikele ukuvuvukala kanye nezinye izinkinga.

1.2 Khulisa ukubonana
I-CMC ingaguqula i-viscosity yoketshezi lokumba, ithuthukise amandla okumba uketshezi ukuze uthwale ukusika, futhi uvikele ukuvalwa komthombo. Ngaphezu kwalokho, umphumela wokulungiswa kwe-viscosity we-CMC usiza ukuthuthukisa izakhiwo zesimbozo soketshezi lokumba, okwenza lufaneleke kakhulu ezindaweni eziyinkimbinkimbi zokumba.

1.3 uhlelo oluqinile lokumba uketshezi
I-CMC inokumelana nosawoti okuhle kanye nokumelana okushisa okuphezulu kwamanzi okumba. Ilungele kakhulu imisebenzi yokumba ngaphansi kosawoti ophakeme, ukwakheka okuyinkimbinkimbi kanye nezimo zokushisa eziphakeme. Kungavimbela ngempumelelo uketshezi lokudonsa kusuka ekuwohlokeni nangokwehluleka ngenxa yokungenelela kwe-electrolyte.

2. Isicelo ku-Fluid Recoon
Ukuqedelwa uketshezi kuwuketshezi olusetshenziselwa ukuhlanza umthombo futhi kuvikele i-oyili negesi reservoir ngemuva kokumba. I-CMC nayo idlala indima ebalulekile ku-fluids:

2.1 Vimbela ukungcoliswa kwe-kawoyela nokuguquguquka kwegesi
I-CMC inganciphisa ukubhebhetheka koketshezi lokuqedelwa, vimbela uketshezi kusuka kuzinsimbi ezihlaselayo ezihlaselayo kanye nezendlalelo zegesi futhi kubangele ukungcoliswa, futhi ngasikhathi sinye kunciphise ukulimala kwamachibi, ngaleyo ndlela kunciphise ukulimala kwamafutha nokukhiqizwa kwegesi.

2.2 Nikeza nge-Filter Cake Cake Coversage
Ngokwakha ikhekhe le-Uniform ne-Low-Permeabity Cleake, i-CMC ingavikela isakhiwo se-reservoir, ivikele ukulimala ekwakhekeni okuzungeze i-Wellbore, futhi kuqinisekiswe ukusebenza koketshezi lokuqeda.

3. Isicelo ku-Cecting Slurry
I-Cementing Slurry isetshenziselwa ukulungisa ukumba kwe-casing bese ugcwalisa i-annulus phakathi komthombo kanye nokwakhiwa. Ukungezwa kwe-CMC kungakhulisa kakhulu ukusebenza kwe-slurry e-cementing:

3.1 Khulisa i-Rheology
I-CMC ingathuthukisa izakhiwo zesimbozo se-slurry yesiko, enze i-slurry ebushelelezi ngesikhathi sokupompa, futhi ngasikhathi sinye ngcono ukufana kokugcwaliswa kwe-slurry.

3.2 Thuthukisa ukulawulwa kokulahlekelwa kwamanzi
Ukungezwa i-CMC ku-slurry yesiko kunganciphisa ukulahleka kwamanzi okushibilika futhi kwakha ikhekhe le-slurry eliminyene le-slurry, ngaleyo ndlela livikele udonga oluhle nokungcola okuhle okubangelwa ukulahlekelwa kwamanzi noma ukungcola okuhle.

3.3 Thuthukisa ukuqina okufushane
Imiphumela yokuqina nokuqina kwe-CMC ingavimbela ukunxusa okufushane futhi iqinisekise ukuthi i-homogeneity namandla okonakalisa i-slurry, ngaleyo ndlela ithuthukise ukuthembeka kwemisebenzi yokuzimela.

4. Eminye imisebenzi kwinqubo yokumba
Ngaphezu kwezinhlelo zokusebenza eziphambili ezishiwo ngenhla, i-CMC ingadlala neqhaza elisekelayo ezicini eziningi zokumba uwoyela:

4.1 Ukusebenza Kwe-Anti-Corrosion
I-CMC inokuqina okuthile kwamakhemikhali, kungavimba izingxenye ezilimazayo ekuvutheni uketshezi nezinye izithasiselo, futhi zivikele imishini namapayipi.

4.2 Thuthukisa ukusebenza kwemvelo
Njengokuphuma kwemvelo, i-CMC ine-biodegradadating ephezulu yokushayela uwoyela futhi inganciphisa ukungcoliswa kwemvelo kokudonswa kwemfucuza.

4.3 Yehlisa izindleko
Ngenxa yokusebenza okuphezulu kwe-CMC, kungafinyelela imiphumela emihle ngokusetshenziswa okuncane, ngakho-ke kunganciphisa izindleko zizonke zokushayela uwoyela ngezinga elithile.

I-5. Amacala ajwayelekile wesicelo
Kweminye imisebenzi yokumba okunzima, efana nemithombo ejulile, imithombo ejulile ye-Ultra-ejulile kanye nokushayela okuyinkimbinkimbi, i-CMC isetshenziswa kabanzi ngenxa yokusebenza kwayo okuhle. Isibonelo, ekuvuthweni kwamafutha okusogwini, i-CMC ingathuthukisa kakhulu ukusebenza koketshezi lokumba ezindaweni ezinosawoti aphezulu, ukuqinisekisa ukusebenza okuphephile nokusebenzayo.

I-6. Ukuqondiswa Kwentuthuko Yesikhathi Esizayo se-CMC
Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba uwoyela, ukusetshenziswa kwe-CMC nakho kuyanda njalo. Ngakolunye uhlangothi, ukumba izithasiselo fluid ngokusebenza okungcono kungathuthukiswa ngokuhlanganisa nezinye izinto ze-polymer; Ngakolunye uhlangothi, ukwenza kahle inqubo yokukhiqiza ye-CMC, ukunciphisa izindleko zayo kanye nokwenza ngcono ukuvikelwa kwemvelo kuzoba ukugxila kocwaningo lwesikhathi esizayo.

I-CMC isetshenziswa ekubizeni uwoyela kuyo yonke indawo yokumba, ukuqeda kanye nenqubo yokumema. Ukusebenza kwayo okuhle kakhulu akugcini nje ngokuthuthukisa ukusebenza kahle kokumba, kodwa futhi kudlala indima ebalulekile ekuvikeleni ama-reservors kanye nemvelo. Lesi sengezo esiguquguqukayo sizoqhubeka nokudlala indima ebalulekile ekuvuthayo kowoyela okuzayo.
