Ngabe i-polyanionic cellule inzuzo kanjani ukumba kwamafutha?

1. Isingeniso
Ukushayela uwoyela kungukusebenza kobunjiniyela obuyinkimbinkimbi obudinga ukusetshenziswa kwamakhemikhali ahlukahlukene ukwenza ngcono ukusebenza koketshezi lokumba. Ukushayela uketshezi akugcini nje ngokugcoba futhi kuphole ngesikhathi sokumba, kepha futhi kusize ukuphatha ukusikwa, ukuvimba ukuwa kahle, futhi kugcinwe umfutho omuhle. I-Polyanionic Cellulose (PAC) isengezo esivame ukusetshenziswa ku-dring fluid futhi sidlala indima ebalulekile ekushayweni kowoyela ngokusebenza kwayo okuphezulu.

2. Izakhiwo zamakhemikhali ze-polyanionic cellulose
I-Polyanionic Cellulose (PAC) iyisisulu se-cellulose enamaqembu e-anionic esakhiweni sayo samangqamuzana. I-PAC ingahlukaniswa izigaba ezimbili: i-viscosity ephansi (LV-PAC) kanye nokubonakala okuphezulu (HV-PAC), ngokususelwa ekusebenzeni kwabo okubonakalayo kwikhambi elinamanzi. Izakhiwo ze-anionic ze-PAC zikwenza ukwazi ukwenza i-sol ezinzile kwisisombululo esingamanzi, okubaluleke kakhulu ekushintsheni kwezinto ezimbobo zoketshezi.

3. Indima e-Drilling Fluids

3.1 Ukulungiswa kwe-Viscosity
I-PAC ikakhulukazi iguqula i-viscosing yokumba uketshezi ngokuqina. I-Peight-Viscosity PAC ingakhulisa kakhulu ukubonakala koketshezi lokumba, ngaleyo ndlela kuthuthukise amandla alo okuphatha ukusika. Lokhu kubalulekile ukugcina kahle kuhlanzekile, ukuvimbela ukuqhekeka okuncane, kanye nokwenza ngcono ukumba. I-Pac-Viscosity Pac isetshenziswa ezimweni lapho imfuneko yensizwa yokumba uketshezi iphansi. Indima yayo ukuhlinzeka ngomphumela wokuqina olinganiselayo wokuqinisekisa ukulinganisela phakathi kwe-fluority kanye nokuphatha umthamo.

3.2 Ukusebenziseka kwezakhiwo ze-Rheological
Izakhiwo ze-Rheological zoketshezi lokumba, okungukuthi, izici zalo zokugeleza kanye nezimo zodonga, ziyisici esibalulekile esithinta ukuqina kwenqubo yokumba. I-PAC ingaguqula ukusebenza okunciphise ukuncipha koketshezi lokumba ukuze kugcinwe khona i-viscosity ephansi ngamanani aphezulu we-shear kanye nokubonakala okuphezulu ngamanani aphansi we-shear. Le mpahla ye-Rheological isiza ukunciphisa ukumelana kwezingxabano ngaphansi kwezimo eziphakeme zokugeleza futhi ithuthukise umthamo othwala uketshezi oludonsa ngaphansi kwezimo eziphansi zokugeleza ngaphansi kwezimo eziphansi zokugeleza.

3.3 Ukulawulwa kokulahlekelwa kwamanzi
I-PAC inamakhono amahle okulawula okuhlunga, anganciphisa ukungena kwamanzi ofuzini okumba ekwakhiweni okuzungeze i-Wellbore. Lokhu kusiza ukugcina ukuqina komthombo futhi kuvimbele ukuwa kahle okubangelwa ukulahleka kwamanzi. Ngokwakha ifilimu elincanyana, i-PAC ilawula ngempumelelo ukulahleka kokuhlunga koketshezi lokumba futhi ivikele ubuqotho bodonga kahle.

4. Izinzuzo zesicelo

4.1 Thuthukisa ukusebenza kahle kokumba
Imiphumela yokuqina kaPac kanye ne-Rheological ukulungiswa inika amandla ukushayela uketshezi ukuze uthwale ukusika kahle, ngaleyo ndlela kunciphise ubungozi bokuqhekeka okuncane kwe-drill kanye nejubane lokumba elandayo. Ngaphezu kwalokho, ukusetshenziswa kwe-PAC kubuye kunciphise ukumelana nokushayisana ngesikhathi sokumba, okuvumela ukushayela kube lula ukugijima kahle, kuthuthukiswa kakhulu ukucubungula.

4.2 Yehlisa Umthelela Wezemvelo
I-PAC iyisengezo esinobungani bemvelo nge-biodegrade enhle. Ngesikhathi sokumba uwoyela, ukusetshenziswa kwe-PAC kunganciphisa umthelela emvelweni, ikakhulukazi lapho usebenzelana nokudonswa kwemfucuza kanye nokuvuselelwa koketshezi. Uma kuqhathaniswa nezinye izengezo zamakhemikhali, i-PAC ayilimazi kakhulu ku-ecosystem futhi isiza ukufeza ukumba okuluhlaza.

4.3 Ukusebenza kwezindleko
Ukusetshenziswa kwe-PAC ekuvuthweni kwamafutha akugcini nje ngokuthuthukisa ukusebenza kahle kokusebenza, kepha futhi kunciphisa inani lokushayela uketshezi kanye nezindleko zokulungiselela. Ukusebenza kahle okuphezulu kanye nomnotho we-PAC kwenze kube ngenye yezithasiselo ezithandwayo ekuvuneni uketshezi. Ngenxa yokusebenza kwayo okuhle, i-PAC inganciphisa isidingo samanye amakhemikhali abizayo kwinqubo yokumba, ngaleyo ndlela anciphise izindleko ezisebenzayo.

5. Amacala wangempela kanye nezinhlelo zokusebenza

5.1 Ukushayela Offshore
I-PAC isetshenziswa kabanzi lapho kulungiswa uketshezi lokumba emisebenzini yokumba ngaphandle kolwandle. Isibonelo, ekusebenzeni kokumba endle endle eNyakatho nolwandle, ukusetshenziswa kwe-PAC kuthuthukise ngempumelelo amandla okumba uketshezi lokuthwala ukusika, kuncishiswe isikhathi sokuphumula ngesikhathi sokumba, kanye nokwenza ngcono ukumba okuphelele. Ngaphezu kwalokho, ukusebenza kwe-PAC's Filtration Control ukusebenza kuhle kakhulu ezindaweni eziyinkimbinkimbi zasolwandle, ukuvikela ngempumelelo ukuwa kwe-Wellbore.

5.2 Ukushisa okuphezulu nokushayela okuphezulu kwengcindezi
I-PAC ibonisa ukuqina okuhle nokusebenza ngaphansi kokushisa okuphezulu kanye nezimo eziphakeme (HPHT). Ngemuva kwenkampani kawoyela yasebenzisa i-PAC endaweni yokushisa ephezulu kanye nengcindezelo ephezulu kakhulu eMiddle East, kwathuthukisa kakhulu ukuqina kanye nokuqina kwenqubo yokumba, futhi kunciphise ubungozi nezindleko ezibangelwa ukwehluleka koketshezi.

6. Ukubukwa kwesikhathi esizayo
Ngentuthuko eqhubekayo yobuchwepheshe bokumba uwoyela, izidingo zokuqhuma koketshezi futhi ziphezulu. Esikhathini esizayo, i-polyanionic cellulose izoqhubeka nokudlala indima ebalulekile kulezi zinto ezilandelayo:

Ukusebenza kahle okuphezulu nokuvikelwa kwezemvelo: Izici zokuvikela ezemvelo ze-PAC zizokwenza ukuthi zikwazi ukuqhubeka nokudlala indima ebalulekile ekuthuthukiseni uketshezi oluhlaza okotshani nokukhuthaza ukuthuthukiswa kobuchwepheshe bokumba okuqinile.
Izengezo Ezinhlekeleleni: Ucwaningo lwesikhathi esizayo lungagxila ekuthuthukisweni kwe-PAC Derivatives enemisebenzi eminingi, ukuze ithuthukise ukusebenza koketshezi ngenkathi imelana nemiphumela ephakeme, njengokumelana nosawoti.
I-Intelligent Control: Ngokuhlanganiswa kwe-nanotechnology kanye nezinto zokwakha ezihlakaniphile, ama-PAC wesikhathi esizayo angahle abe nokusebenza okusebenzayo futhi angakwazi ukulungisa ngokuzenzakalelayo ukusebenza koketshezi lokumba ngokwezidingo zesikhathi sangempela ngesikhathi sokumba.

Njengomsebenzi osebenzayo futhi osebenzayo we-fluid fluid, i-polyanionic cellulose (PAC) idlala indima enkulu kwinqubo yokumba kawoyela. Ngokulungisa i-viscosity, ukulungiselela izakhiwo zembongo kanye nokulawula ukulahleka kwamanzi, i-PAC ngempumelelo ithuthukisa ukusebenza kahle kwemvelo, inciphisa umthelela wezemvelo, futhi ilethe izinzuzo zezomnotho ezibalulekile. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, amathemba wesicelo se-PAC azobanzi, enza iminikelo enkulu ekuthuthukisweni nasekuthuthukisweni okuqhubekayo kobuchwepheshe bokumba uwoyela.
