I-CMC (i-carboxymethyl celtuleose) Ingabe izengezo zamakhemikhali zisetshenziswa kabanzi embonini yokumba kawoyela, ikakhulukazi njenge-smighter kanye ne-stabilizer yoketshezi lokumba. Umthelela wayo ekusebenzeni kahle kokumba uyenziwa ama-multifaceted futhi kungaxoxwa kusuka ekuhlolweni kokwenza ngcono ukusebenza kwamanzi uketshezi, ukunciphisa izinkinga ngesikhathi senqubo yokumba, nokwenza kahle inqubo yokumba.
1. Imisebenzi eyisisekelo ye-CMC
umphumela wokuqina
I-CMC ingakhulisa kakhulu ukubonwa koketshezi lokumba. Le mpahla ibalulekile ekusebenzeni kokumba ngoba uketshezi olunamafutha agqinsiwe lunganikeza amandla angcono kakhulu namakhono okuhamba, ukusiza ukususa ukusika kusuka ku-Wellbore futhi kuvikele ukubekwa kwabo. Ngasikhathi sinye, ukuhlakanipha okuphezulu kusiza ukugcina ukumiswa okuhle ekwakhiweni okuyinkimbinkimbi futhi kuvimbela ukusika kuvale umthombo.
Ukuqina okuwuketshezi
I-CMC ine-solubility yamanzi eqinile nokushisa okuhle nokumelana nosawoti, okuvumela ukuthi isebenze ngokumangala ngaphansi kwezimo ezahlukahlukene zezwe. Ukuqina kwayo okuhle kwamakhemikhali kanye nokuthambisa kwezakhiwo kunciphisa izinkinga ezahlukahlukene ezibangelwa ukungazibangeli koketshezi lokumba ngesikhathi senqubo yokumba, njengokuvundula kodaka, ukuphunyuka kwe-njde, njll.
Yehlisa ukulahleka koketshezi kodaka olususelwa emanzini
Ngokusebenzisana nezinye izinto, i-CMC inganciphisa ngempumelelo ukulahleka kokuhlunga koketshezi lokumba, ngaleyo ndlela kuvikele amanzi ekungeneni ungqimba olungaphansi komhlaba, ukunciphisa ukulimala kwezindawo ezizungezile, nokuvikela udonga olunzulu.
2. Umthelela othize we-CMC ekusebenzeni kahle kokumba
Thuthukisa ukusebenza kokuhlanza koketshezi lokumba
Ngesikhathi senqubo yokumba, ukungqubuzana phakathi kwe-drill bit kanye nokwakheka kuzokhiqiza inani elikhulu lokusika. Uma zingasuswa ngesikhathi, kuzodala ukuphazamiseka ekusebenzeni kokumba. I-CMC ithuthukisa ukumiswa kanye nokuphatha umthamo wokumba uketshezi, ongakulethela kahle lezi zigayelwe emthonjeni ukuze uqinisekise ukuhlanzeka komthombo. Lo msebenzi ubaluleke kakhulu ezinhlotsheni ezinzima ezifana nemithombo ejulile, imithombo ejulile ye-Ultra-ejulile, nemithombo evundlile. Kungagwema ngempumelelo izinkinga ezinjengokwehliswa kwe-Wellbore nokunamathela kancane, ngaleyo ndlela kukhule ngejubane lokumba.
Yehlisa ubungozi bokuwa kwe-shaft
Kwezinye izindlela zedwala ezithambile noma ezixegayo, enye yemisebenzi eyinhloko yoketshezi lokumba ukulondolozela ukuqina kodonga lwe-Wellbore. Njengomkhulu, i-CMC ingathuthukisa ukunamathela koketshezi lokumba, okuvumela uketshezi lokumba lakha ifilimu evikelayo odongeni kahle ukuvikela ukwakhiwa kahle noma udaka kusuka ekungeneni kwangena ekwakhekeni kwamatshe edwala. Lokhu akugcini nje ngokuthuthukisa ukuphepha kokusebenza kokumba, kepha futhi kunciphisa isikhathi sokuphumula okubangelwa ukungazinzili kahle, ngaleyo ndlela kuthuthukise ukusebenza kahle kokumba.
Yehlisa Ukudla Ukulahleka Kwomoya
Ngesikhathi senqubo yokumba, uketshezi oludonsa lungangena ekwakhekeni komhlaba angaphansi komhlaba, ikakhulukazi ezindaweni lapho idwala line-porsosi noma ama-fractures aphezulu. I-CMC ingalawula ngempumelelo ukulahleka koketshezi koketshezi lokumba futhi kunciphise ukulahleka koketshezi lokumba kuma-pores kanye nama-fractures. Lokhu akusizi nje kuphela ukonga izindleko ze-fluid, kepha futhi kuvimbela uketshezi lokushayela kusuka ekulahlekelweni ngokushesha nangokuthinta imisebenzi, ukuqinisekisa ukuthi uketshezi lokudonsa luyaqhubeka nokwenza imisebenzi yalo ngempumelelo.
Thuthukisa ukusebenza kahle kokumba kanye nomjikelezo wokumba emfushane
Ngoba i-CMC ithuthukisa ukusebenza koketshezi lokumba, isebenza kangcono ekuhlanzeni kahle i-Wellbore, ihlanze udonga kahle, futhi iphethe izinkinga ezahlukahlukene, ngaleyo ndlela zinciphise izinkinga ezahlukahlukene zokubamba kanye nokuqinisekisa ukuthi ukusebenza kokumba kungaba bushelelezi. futhi wenze kahle. Ukuqina nokusebenza kokuhlanzeka koketshezi lokumba kuthinta ngqo inqubekela phambili yokumba. Ukusetshenziswa kwe-CMC kwandisa isivinini sokumba, ngaleyo ndlela kunciphise umjikelezo wokumba futhi kunciphise izindleko zokusebenza okuphelele.
3. Izibonelo zohlelo lokusebenza kanye nemiphumela esebenzayo ye-CMC
Ukumba okujulile okujulile
Ekumbenina okujulile, njengoba ukujula kokushayela kukhuphuka futhi ukucindezela kwe-Wellhead kwanda, ukuqina nokumiswa koketshezi lokumba kubaluleke kakhulu. Ngokwengeza i-CMC, i-viscosity yoketshezi lokumba ingathuthukiswa, umthamo ophethe ama-cuttings angathuthukiswa, futhi ukusakazwa okubushelelezi koketshezi lokumba kungaqinisekiswa. Ngaphezu kwalokho, i-CMC inganciphisa ngempumelelo imfucuza yesikhathi ebangelwa ukuwa odongeni kahle kanye nokuvuza, ukuthuthukisa ukusebenza kahle kokumba okujulile.
Izinga lokushisa eliphakeme kanye nokuhlobisa okuphezulu kwengcindezelo
Ngokwakhekeni okunamazinga okushisa aphezulu nezingcindezi eziphakeme, uketshezi oludonsa ludinga ukuba nokuqina okuphezulu nokuphikiswa kwengcindezi. I-CMC ayikwazi ukukhipha umphumela wokuqina kumazinga okushisa ajwayelekile, kepha futhi igcina ukuqina okuhle ezindaweni eziphakeme zokushisa ukuze ugweme ukonakala kokusebenza kwamanzi okumba. Kuzinhlelo zokusebenza ezisebenzayo, i-CMC inciphisa ukudonsa ukulahleka koketshezi ngesikhathi sokumba kulezo zinto futhi kunciphisa isikhathi sokuphumula okubangelwa yizinkinga zokumba uketshezi.
ukumba okuvundlile kahle
Ngesikhathi senqubo yokumba imithombo evundlile, ngoba ukuzinza kodonga kahle kanye nokususwa kwama-cuttings kuyinkimbinkimbi ikakhulukazi, ukusetshenziswa kweCm njengoba ubukhulu bunemiphumela ebalulekile. I-CMC ingathuthukisa ngempumelelo i-RHEREOLOGY SORDING Fluid, isize uketshezi lokumba ligcina ukumiswa okuhle kanye namakhono okuhamba, ukuze ama-cuttings angathathwa ngesikhathi, agweme izinkinga ezinamabala nokuvinjwa, kanye nokwenza ngcono ukusebenza kahle kokumba kahle okuvundlile.
Njengomfashini osebenzayo we-fluid fluid, isicelo se-CMC kwinqubo yokumba kuthuthukisa ukusebenza kahle kokumba. Ngokuthuthukisa i-viscosity, ukuqina kanye nezinto ezinombozo zokumba uketshezi, i-CMC idlala indima ebalulekile ekuhlanzeni kahle, ukunciphisa ukuwa kodonga kahle, nokulahlekelwa ukulahleka koketshezi, kanye nejubane lokumba elandayo. Ngokuthuthuka okuqhubekayo kobuchwepheshe bokumba, i-CMC inamathemba okusebenza abanzi ezindaweni ezahlukahlukene eziyinkimbinkimbi futhi azoqhubeka nokudlala indima ebalulekile ekusebenzeni kokumba okuzayo.
