Iyini ukusetshenziswa kwe-cellulose ekumba udaka?

I-Cellulose iyinhlanganisela eguquguqukayo, futhi enye yezindlela ezisetshenziswa ngayo ezingaziwayo emkhakheni wokumba udaka.Ukumba udaka, okwaziwa nangokuthi uketshezi lokumba, kudlala indima ebalulekile enqubweni yokumba uwoyela negesi.Lenza imisebenzi eminingi, ehlanganisa ukupholisa kanye nokugcoba i-drill bit, ukuthutha okusikiwe phezulu, kanye nokuhlinzeka ngosekelo lokuvimbela ukuwa kwe-wellbore.I-Cellulose yengezwa ekubunjweni kodaka ngenxa yezakhiwo zayo eziyingqayizivele ezisiza ukuthuthukisa ukusebenza kahle okuphelele kwenqubo yokumba.

1. Ukulawulwa kwe-Viscosity:

Lapho i-cellulose yengezwa odakeni lokumba, isebenza njenge-viscosifier.Isiza ukulawula i-viscosity yodaka, iqinisekise ukuthi inokuvumelana okulungile ukuthutha ama-drill cuttings phezulu.I-viscosity yodaka ibalulekile ekusebenzeni kahle, futhi i-cellulose isiza ukugcina izici zokugeleza ezidingekayo.

2. Ukulawula ukulahleka kwamanzi:

Enye yezinselelo emisebenzini yokumba ukulahlekelwa udaka lokumba lungene ekwakhekeni, into eyaziwa ngokuthi ukulahlekelwa uketshezi.I-Cellulose isebenza njenge-ejenti yokulawula ukuhlunga, idala umgoqo ovimbela ukulahlekelwa ngokweqile koketshezi lokumba ekwakhekeni kwamadwala azungezile.Lesi sakhiwo sibalulekile ekugcineni ukusimama kwe-wellbore.

3.Ukulawula isihlungi:

Ukulawula ukuhlunga kungenye into ebalulekile ekusebenzeni kodaka.Izinhlayiya ze-cellulose zakha ikhekhe lokuhlunga ezindongeni zomthombo, ukuvimbela izinhlayiya ezinhle ukuthi zingangeni ekubunjweni.Lokhu kusiza ukugcina ubuqotho bomthombo futhi kuthuthukisa ukusebenza kahle okuphelele kwenqubo yokumba.

4. Izinga lokushisa elizinzile:

Imisebenzi yokumba ngokuvamile ihlangabezana nezimo ezishintshayo zokushisa, futhi i-cellulose ikhombisa ukuzinza ebangeni lokushisa elibanzi.Lokhu kuyenza ibe yingxenye ebalulekile yokumba ukwakheka kodaka, iqinisekisa ukuthi uketshezi lugcina ukusebenza kwalo ngisho nasezimweni zemvelo eziyinselele.

5. Ukucatshangelwa kwemvelo:

I-Cellulose iyinto ebolayo futhi ehambisana nemvelo.Njengoba imithetho yemvelo embonini kawoyela negesi iba namandla, ukusebenzisa i-cellulose ekumba udaka kuhambisana nezinjongo zokusimama.Yehlisa umthelela wemvelo ohambisana nemisebenzi yokumba.

6. Izakhiwo ezingenabuthi:

I-Cellulose ayinabo ubuthi, okwenza kube ukukhetha okuphephile kokumba udaka.Izakhiwo ezingenabo ubuthi zibaluleke kakhulu uma kucutshungulwa umthelela ongaba khona wemisebenzi yokumba ezindaweni ezizungezile, ikakhulukazi ezimeni zokumba ogwini.

7. Thuthukisa ukusebenza kodaka:

Ukwengeza i-cellulose odakeni lokumba kungasiza ukuthuthukisa ukusebenza kodaka kukonke.Isiza ukufeza izimo zokumba ezilungile ngokuthuthukisa izakhiwo ze-rheological zodaka, ukunciphisa ukungqubuzana nokuthuthukisa amandla okuthwala ama-cuttings.

8. Ukuhambisana nezinye izithasiselo:

I-Cellulose iyahambisana nezinhlobonhlobo zezinye izithasiselo zodaka zokumba.Ukuguquguquka kwayo kuvumela izinhlelo zodaka ukuba zenzelwe izimo ezithile zokumba nezinselele.Lokhu kuhambisana kuthuthukisa ukusebenza kahle jikelele kodaka lokumba.

I-Cellulose idlala indima ebalulekile ekumba udaka, isiza ekulawuleni i-viscosity, ukulawula uketshezi oluphumayo, ukulawula ukuhlunga, ukuzinza kwezinga lokushisa, ukucatshangelwa kwemvelo, izici ezingenabo ubuthi, izakhiwo zodaka ezithuthukisiwe, nokuhambisana nezinye izithasiselo .Izakhiwo zayo eziyingqayizivele ziyenza ibe yingxenye ebalulekile yemboni kawoyela negesi, iqinisekisa ukusebenza kahle nokuqhubekayo kokumba.
