I-Carboxymethyl Cellulose (CMC) iyi-ejenti ekhulisa i-viscosity esetshenziswa kabanzi kuketshezi lokumba futhi inokuncibilika okuhle kwamanzi kanye nomphumela wokujiya.
1. Thuthukisa i-viscosity kanye nezakhiwo zokunciphisa i-shear
I-CMC yenza isixazululo esine-viscosity ephezulu lapho sincibilika emanzini. Amaketanga awo amangqamuzana anda emanzini, akhulise ukungqubuzana kwangaphakathi koketshezi futhi ngaleyo ndlela andise i-viscosity yoketshezi lokumba. I-viscosity ephezulu isiza ukuthwala nokumisa ukusikwa ngesikhathi sokumba futhi kuvimbela ukusikwa ekuqongeleleni phansi komthombo. Ukwengeza, izixazululo ze-CMC zibonisa izakhiwo zokuhlanjululwa kwe-shear, okungukuthi, i-viscosity iyancipha ngezinga eliphezulu lokugunda, okusiza uketshezi lokumba lugeleze ngaphansi kwamandla aphezulu okugunda (njengaseduze kwe-drill bit) ngenkathi kumazinga aphansi okugunda (njengaku-annulus. ). gcina i-viscosity ephezulu ukuze umise ngempumelelo ukusika.
2. Thuthukisa i-rheology
I-CMC ingathuthukisa kakhulu i-rheology yokumba uketshezi. I-Rheology ibhekisela ekuguqukeni nasekugelezeni izici zoketshezi ngaphansi kwesenzo samandla angaphandle. Phakathi nenqubo yokumba, i-rheology enhle ingaqinisekisa ukuthi uketshezi lokubhoboza lunokusebenza okuzinzile ngaphansi kwengcindezi ehlukene kanye nezimo zokushisa. I-CMC ithuthukisa ukusebenza kahle kokubhola nokuphepha ngokushintsha ukwakheka koketshezi lokumba ukuze lube ne-rheology efanele.
3. Thuthukisa izinga lekhekhe lodaka
Ukwengeza i-CMC kuketshezi lokumba kungathuthukisa ikhwalithi yekhekhe lodaka. Ikhekhe lodaka ifilimu elincanyana elakhiwe ngokumba uketshezi odongeni lokumba, elidlala indima yokuvala izimbotshana, ukusimamisa udonga lomthombo nokuvimbela ukulahlekelwa uketshezi lokumba. I-CMC ingakha ikhekhe lodaka eliminyene neliqinile, inciphise ukungena nokuphuma kwesihlungi sekhekhe lodaka, ngaleyo ndlela ithuthukise ukuzinza kodonga lomthombo futhi ivimbele ukubhidlika nokuvuza kahle.
4. Lawula ukulahleka kwesihlungi
Ukulahlekelwa uketshezi kubhekisela ekungeneni kwesigaba se-liquid oketshezini lokumba kuma-pores okwakheka. Ukulahlekelwa uketshezi ngokweqile kungaholela ekungazinzini kodonga lomthombo ngisho nokuqhunyiswa. I-CMC ilawula ngokuphumelelayo ukulahlekelwa koketshezi ngokwenza isixazululo se-viscous oketshezini lokubhoboza, ikhulise i-viscosity yoketshezi futhi ibambezele izinga lokungena kwesigaba soketshezi. Ngaphezu kwalokho, ikhekhe lodaka lekhwalithi ephezulu elakhiwe yi-CMC odongeni lomthombo liphinde livimbele ukulahleka koketshezi.
5. Izinga lokushisa nokumelana nosawoti
I-CMC inokushisa okuhle nokumelana nosawoti futhi ifanele izimo ezihlukahlukene zokwakheka eziyinkimbinkimbi. Ezindaweni ezishisa kakhulu nezinosawoti omningi, i-CMC isengakwazi ukugcina umphumela wayo okhulisa i-viscosity ukuze kuqinisekiswe ukusebenza okuzinzile koketshezi lokumba. Lokhu kwenza i-CMC isetshenziswe kabanzi ezindaweni ezeqisayo ezifana nemithombo ejulile, imithombo eshisa kakhulu, kanye nokumbiwa kolwandle.
6. Ukuvikelwa kwemvelo
Njengempahla ye-polymer yemvelo, i-CMC iyakwazi ukubola futhi inobungani nemvelo. Uma kuqhathaniswa namanye ama-polymer tackifiers okwenziwa, i-CMC inokusebenza kwemvelo okuphakeme futhi ihlangabezana nezidingo zemboni yesimanje ye-petroleum yokuvikela imvelo kanye nentuthuko esimeme.
I-Carboxymethylcellulose (CMC) idlala izindima ezahlukahlukene njenge-ejenti ekhulisa i-viscosity kuketshezi lokumba. Ithuthukisa kakhulu ukusebenza koketshezi lokumba futhi iqinisekise ukuqhubeka kahle kwenqubo yokumba ngokwandisa i-viscosity kanye ne-shear dilution, ukuthuthukisa i-rheology, ukuthuthukisa ikhwalithi yekhekhe lodaka, ukulawula ukulahlekelwa uketshezi, izinga lokushisa nosawoti ukumelana, nokuvikelwa kwemvelo. Ukusetshenziswa kwe-CMC akuthuthukisi nje kuphela ukusebenza kahle kokubhola nokuphepha, kodwa futhi kunciphisa umthelela wendawo. Kuyisici esibalulekile nesibalulekile ekubhojweni okusamanzi.
