Iqhaza le-carboxymethyl cellulose (CMC) odakeni

I-Carboxymethyl Cellulose (CMC) iyingxenye evamile ye-polymer esetshenziswayo esetshenziswa kabanzi ezinkundleni ezahlukahlukene zezimboni. Ikakhulu ekubizeni nobunjiniyela be-petroleum, i-CMC idlala indima ebalulekile njengesengezo sodaka. Imisebenzi yayo eyinhloko ukuthuthukisa izakhiwo ze-bheological, ukukhulisa ukuqina kodaka, ukuthuthukisa ukulambisa, ukunciphisa ukugqoka okuncane, njll.

1. Khulisa ukubonana kodaka
I-viscosity kadaka ibalulekile ekusebenzeni kokumba. I-viscosity ephansi kakhulu ayikwazi ukususa ngempumelelo ukusikwa okukhiqizwe ngesikhathi sokumba, futhi okuphezulu kakhulu kuzothinta ukubizeka kanye nokusebenza kahle kodaka. I-CMC ingakhulisa ngempumelelo ukubonwa kodaka ngokuxhumana ngama-molecule amanzi ngeqembu le-carboxylmethyl ehlelweni lwayo lamangqamuzana. Ama-molecule e-CMC akha isakhiwo senethiwekhi emanzini, angadonsa amanzi futhi avuvukele futhi akhuphule ukubonwa koketshezi, ngaleyo ndlela athuthukise izakhiwo ze-bherological zodaka. Le mpahla ibaluleke kakhulu ekususeni ukusikwa nokuzinza udonga lweBorehole ngesikhathi sokumba.

Izakhiwo ze-Rheological zodaka (kufaka phakathi i-viscosity, uketshezi, njll.) Zibaluleke kakhulu kwinqubekela phambili ebushelelezi yokusebenza. I-CMC ingakhulisa kakhulu ukubonakala kwepulasitiki kanye nenani lesivuno sodaka ekuhluphisweni okuthile, lungisa izakhiwo ze-bhedi, futhi uqinisekise ukuthi udaka lunobubi obuhle nokuthambisa ngesikhathi sokumba. I-viscosity eyengeziwe isiza ukunciphisa ukumelana nokugeleza kodaka, ngaleyo ndlela kuthuthukise ukusebenza kahle kokumba nokunciphisa ukugqokwa kokulimala okubangelwa ukweqiwa ngokweqile ngesikhathi sokumba.

3. Ukuthuthukisa ukuqina kodaka
Ngesikhathi senqubo yokumba, ukuqina kodaka kubalulekile, ikakhulukazi ngaphansi kwezindawo ezahlukahlukene zendawo kanye nezinguquko zokushisa. Ngenxa ye-solubility yayo enhle nokuqina, i-CMC ingathuthukisa ukumelana nokushisa nodaka kasawoti, ukuze kusakwazi ukugcina ukusebenza okuphezulu ngaphansi kwezimo ezihlukile zokumba. I-CMC ingakha isixazululo esizinzile kudaka, ivikele udaka oluvela edidation, e-floccution kanye nezinye izinto zesikhathi, futhi ziqinisekise ukuqina kwesikhathi eside kodaka.

4. Khulisa ukugcotshwa kukadaka
Ngesikhathi sokusebenza kokushayela, ukungqubuzana phakathi kokudla okuncane nokwakheka akunakugwenywa. Ukuxabana ngokweqile kuzokhulisa ukusetshenziswa kwamandla, kunciphise ukusebenza kahle kokumba, futhi kungadala ukulimala kwemishini. I-CMC ingakhulisa kakhulu ukugcoba kukadaka, yehlisa i-coefffity engqubuzana phakathi kwe-drill bit kanye nodonga lwe-borehole, yehlisa ukugqokwa kwe-drill bit, futhi uthuthukise ukuqina kokusebenza ngesikhathi sokumba. Ukuthuthukiswa kokugcoba okusiza ukunciphisa ubungozi bokuwa odongeni kahle ngesikhathi sokumba nokunweba impilo yensiza yemishini.

5. Vimba imifantu nokulawula okuphelele
Ngaphansi kwezinye izimo ezikhethekile zokumba, njengokuhlangana nokuvumela okuphezulu noma ukwakheka okuphukile, i-CMC ingavimba ngempumelelo ama-pores kanye nemifantu ekwakhekeni. Ama-molecule e-CMC anezakhiwo ezinhle ze-GELLIng futhi angakha ama-colloids kumanzi wokumba ukuze anciphise ukuvumela kwamanzi odakeni. Lo mthelela wokuvimba usiza ukuvikela amanzi odaka ekungeneni ungqimba lwamanzi noma ngaphansi kwamafutha negesi, ukunciphisa ukungcoliswa komhlaba kanye nokuvikela izinsiza zangaphansi.

6. Ukumelana nosawoti kanye nokumelana okushisa okuphezulu
Kwelinye i-high-sality kanye nezindawo eziphakeme zokudla okushisa, i-CMC ikhombise ukuzivumelanisa nezimo ezinhle kakhulu. Amaqembu e-carboxyl aqukethwe esakhiweni sawo se-molecular angahlangana ngempumelelo nama-molecule wamanzi ukuthuthukisa i-solubility yayo nokuqina ezindaweni ezinosawoti zamanzi. Lokhu kuvumela i-CMC ukuthi idlale indima ekuhlanzeni nasekuzilonyeni udaka emanzini asawoti. Ngaphezu kwalokho, i-CMC nayo inezinga elithile lokumelana okuphezulu kakhulu futhi akulula ukubola ezindaweni eziphakeme zokushisa, ezisiza ukugcina ukusebenza kodaka okwakha izinga lokushisa eliphakeme.

7. Ukuvikelwa Kwezemvelo
Ngokuthuthuka okuqhubekayo kwezidingo zokuvikelwa kwemvelo, izimboni eziningi zisebenza kanzima ukunciphisa ukungcoliswa kwemvelo. Ekusebenzeni kokumba, izithasiselo zendabuko zendabuko zivame ukuqukethe izithako ezinobuthi, ezingaba nomthelela omubi endaweni yemvelo. Njengomkhiqizo wemvelo, i-CMC isuselwa kwimicu yezitshalo futhi ingadedelwa ngokushesha emanzini, okulimaza kakhulu imvelo. Ngakho-ke, kuyinto eluhlaza okotshani nemvelo enobungane. Izakhiwo zalo ezingezona ezinobuthi futhi ezingcolile zizenza izinto ezithandwayo kumaphrojekthi amaningi okuthuthukisa kawoyela namagesi.

8. Ukushintshwa kwezinye izithasiselo
Kuzinhlelo zokusebenza ezisebenzayo, i-CMC ivame ukuxutshwa nezinye izithasiselo ze-MUD (njenge-polylamide, bentonite, njll.). I-CMC ingahlenza nalezi zengezo ukuze zithuthukise i-Rheology, ukuqina kanye nokuthambisa udaka. Isibonelo, lapho i-CMC ihlanganiswa ne-bentonite, ingathuthukisa ukuqina kwe-colloidal, gwema ukuqina kodaka ngesikhathi sokusetshenziswa, futhi uthuthukise ukuzivumelanisa nezimo zodaka ekushiseni okuphezulu nasezindaweni eziphakeme zokucindezela.

I-Carboxymethyl Cellulose (CMC) idlala izindima eziningi odakeni. Akukwazi ukukhulisa kuphela ukuhlakanipha kanye ne-rheology kadaka, kuthuthukise ukuqina kanye nokuthambisa udaka, kepha futhi kuthuthukisa ukuvikelwa kwemvelo kodaka, kunciphise ukugqokwa kwemishini ngesikhathi sokumba, futhi kunciphise ukumiswa kwemikhuba ekhethekile ngaphansi kwezimo ezikhethekile zezwe lezwe. Njengomshini obalulekile wokumba odaka, i-CMC inokusebenza okuhle kakhulu kanye namathemba okusebenza abanzi, ikakhulukazi emkhakheni wokuvikelwa kwemvelo nokumba okusebenzayo, okubonisa inani layo elingenakusebenza.
