Kungani i-CMC ingasetshenziswa ekumba uwoyela?

I-Carboxymethyl cellulose (CMC) ithola ukusetshenziswa okubanzi ekumba uwoyela ngenxa yezakhiwo zayo ezihlukile ezibhekana nezinselelo ezimbalwa ezihlangatshezwane nenqubo yokumba. Nakhu ukuthi kungani i-CMC isetshenziswa ekumba uwoyela:

1. Ukulawulwa Kwe-Viscosity Yamanzi:

Emisebenzini yokumba uwoyela, uketshezi lokumba (okwaziwa nangokuthi udaka lokumba) lubalulekile ekugcobiseni, ekupholiseni, nasekususeni imfucumfucu. Lawa ma-fluid kumele abe ne-viscosity elawulwayo ukuze akwazi ukuthwala izingcezu zokumba aziyise phezulu futhi agcine uzinzo kumgodi. I-CMC isebenza njengesilungisi se-rheology kuketshezi lokumba, okuvumela onjiniyela ukuthi balawule ngokunembile i-viscosity kanye nokugeleza kwezakhiwo zodaka. Ngokulungisa ukugxila kwe-CMC, abaqhubi bokumba bangakwazi ukulungisa i-viscosity yoketshezi ukuze bahlangabezane nezidingo ezithile zezimo zokumba ezihlukene, njengamazinga okushisa ahlukahlukene kanye nezingcindezi zokubunjwa.

2. Ukulawula Ukuhlunga:

Ukulawula ukulahleka koketshezi noma ukucwengwa kubalulekile ekumbiweni kukawoyela ukuze kuvinjelwe ukulimala kokwakheka nokugcina ukuqina kwe-wellbore. I-CMC isebenza njenge-ejenti yokulawula ukuhlunga ngokwenza ikhekhe lesihlungi elincanyana, elingangeneli odongeni lwe-borehole. Leli khekhe lesihlungi livala kahle ukwakheka futhi linciphisa ukulahlekelwa uketshezi lokumba edwaleni elizungezile, ngaleyo ndlela kuncishiswe umonakalo wokwakheka nokugcina ubuqotho bechibi. Ngaphezu kwalokho, i-CMC isiza ukuthuthukisa ubuqotho nokuqina kwesihlungi, iqinisekisa ukuzinza kwe-wellbore yesikhathi eside ngesikhathi sokumba.

3. Ukumiswa Kwezinsimbi Zokubhoboza:

Ngesikhathi sokumba, ama-rock cuttings akhiqizwa njengoba i-drill bit ingena ezindaweni ezingaphansi komhlaba. Ukumiswa ngendlela efanele kwalezi zicucu oketshezini lokumba kubalulekile ukuze kuvinjwe ukuhlala kwazo kanye nokunqwabelana kwazo phansi kwemgodi, okungakhinyabeza ukuqhubeka kokumba futhi kubangele ukulimala kwemishini. I-CMC isebenza njenge-ejenti elengayo, esiza ukugcina izingcezu zokumba zihlakazekile futhi zimisiwe oketshezini. Lokhu kuqinisekisa ukususwa okuqhubekayo kokusikwa emgodini womthombo futhi kugcina ukusebenza kahle kokubhola.

4. Ukunciphisa Ukulimala Kokwakheka:

Kwezinye izimo zokumba, ikakhulukazi ezindaweni ezibucayi noma ezigciniwe, ukusetshenziswa koketshezi oluthile lokumba kungaholela ekulimaleni kokwakheka ngenxa yokuhlasela koketshezi kanye nokusebenzisana ne-matrix yedwala. Uketshezi lokumba olususelwa ku-CMC lunikeza izinzuzo ekunciphiseni ukulimala kokwakheka, ngenxa yokuhambisana kwazo nezinhlobonhlobo zokwakheka kanye nokusebenzelana okuncane noketshezi okwakheka. Izakhiwo ezingalimazi ze-CMC zisiza ukulondoloza ukungeneka kwe-reservoir kanye ne-porosity, iqinisekisa amazinga alungile okukhiqiza i-hydrocarbon nokusebenza kwedamu.

5. Ukucatshangelwa Kwemvelo Nokuphepha:

Uketshezi lokumba olususelwa ku-CMC luvame ukuthandwa ngenxa yezinzuzo zabo zemvelo nokuphepha. Uma kuqhathaniswa nezinye izithasiselo, i-CMC iyabola futhi ayinabo ubuthi, inciphisa umthelela wemvelo wokumba imisebenzi futhi inciphisa ubungozi kubasebenzi nezilwane zasendle. Ukwengeza, uketshezi olususelwa ku-CMC lukhombisa ubuthi obuphansi futhi lubeka izingozi zezempilo ezincane kubasebenzi abambayo, okunomthelela endaweni ephephile yokusebenza ezindaweni zokumba uwoyela.

Isiphetho:

Sengiphetha, i-CMC isetshenziswa kakhulu emisebenzini yokumba uwoyela ngenxa yekhono layo lokubhekana nezinselele ezihlukahlukene okuhlangatshezwane nazo ohlelweni lokumba. Kusukela ekulawuleni i-viscosity yoketshezi kanye nokuhlunga kuye ekumiseni ukusikwa kokumba kanye nokunciphisa ukulimala kokwakheka, i-CMC idlala indima ebalulekile ekuthuthukiseni ukusebenza kokumba, iqinisekise ukuzinza kwe-wellbore, kanye nokunciphisa umthelela wendawo. Ukuguquguquka kwayo, ukusebenza kahle, nokuphepha kwenza i-CMC ibe isithasiselo esithandwayo ekwakhiweni koketshezi lokumba, okusekela ukuhlola nokukhiqiza uwoyela ngendlela ephumelelayo neqhubekayo.
