ICarboxymethyl Cellulose (CMC) yiarhente yokwandisa i-viscosity esetyenziswa ngokubanzi kulwelo lokomba kwaye inonyibiliko olulungileyo lwamanzi kunye nesiphumo sokujiya.
1. Ukuphucula i-viscosity kunye neempawu zokucheba zokucheba
I-CMC yenza isisombululo esine-viscosity ephezulu xa inyibilika emanzini. Imixokelelwane yayo yeemolekyuli yanda emanzini, inyusa ukukhuhlana kwangaphakathi kolwelo kwaye ngaloo ndlela inyusa i-viscosity yolwelo lokomba. I-viscosity ephezulu inceda ukuthwala kunye nokumisa i-cuttings ngexesha lokugaya kwaye inqande ukusika ukuba kuqokelelwe emazantsi equla. Ukongeza, izisombululo zeCMC zibonisa iipropathi zokucheba zokucheba, oko kukuthi, i-viscosity iyancipha kumazinga aphezulu okucheba, okunceda ukuqengqeleka kolwelo phantsi kwemikhosi ephezulu yokucheba (njengakukufutshane ne-drill bit) ngelixa kumazinga aphantsi okucheba (njengakwi-annulus. ). gcina i-viscosity ephezulu ukumisa ngokufanelekileyo ukusika.
2. Ukuphucula irheology
I-CMC inokuphucula ngokubonakalayo i-rheology yolwelo lokomba. I-Rheology ibhekisela kwi-deformation kunye neempawu zokuhamba kwamanzi phantsi kwesenzo samandla angaphandle. Ngethuba lenkqubo yokugaya, i-rheology efanelekileyo inokuqinisekisa ukuba i-drilling fluid inomsebenzi ozinzile phantsi koxinzelelo oluhlukeneyo kunye neemeko zokushisa. I-CMC iphucula ukusebenza kakuhle kokugrumba kunye nokhuseleko ngokutshintsha ulwakhiwo lwe-drilling fluid ukuze ibe ne-rheology efanelekileyo.
3. Ukuphucula umgangatho wekeyiki yodaka
Ukongeza i-CMC kwi-drilling fluid inokuphucula umgangatho wekeyiki yodaka. Ikeyiki yodaka yifilimu ebhityileyo eyenziwe ngokugrumba ulwelo kudonga lokomba, oludlala indima yokutywina imingxuma, ukuzinzisa udonga lomthombo kunye nokuthintela ukulahleka kolwelo. I-CMC inokwenza ikeyiki yodaka eshinyeneyo kwaye ilukhuni, inciphise ukungeneka kunye nelahleko yokucoca ikeyiki yodaka, ngaloo ndlela iphucula uzinzo lodonga lwequla kunye nokuthintela ukudilika kakuhle kunye nokuvuza.
4. Lawula ilahleko yesihluzi
Ukulahleka kolwelo kubhekiselele ekungeneni kwesigaba solwelo kulwelo lokomba kwimibhobho yokwakheka. Ukulahleka kolwelo olugqithisileyo kunokukhokelela ekungazinzini kodonga lwequla kunye nokuvuthela. I-CMC ilawula ngokufanelekileyo ilahleko yolwelo ngokwenza isisombululo se-viscous kulwelo lokomba, ukwandisa i-viscosity yolwelo kunye nokucothisa izinga lokungena kwinqanaba lolwelo. Ukongeza, ikeyiki yodaka ekumgangatho ophezulu eyenziwe yiCMC eludongeni lwequla ikhusela ngakumbi ukulahleka kolwelo.
5. Ubushushu kunye nokumelana netyuwa
I-CMC inobushushu obulungileyo kunye nokuxhathisa ityuwa kwaye ifanelekile kwiimeko ezahlukeneyo zokwakheka. Kwiindawo ezinobushushu obuphezulu kunye netyuwa ephezulu, i-CMC isenako ukugcina i-viscosity-eyandisa isiphumo sokuqinisekisa ukusebenza okuzinzileyo kolwelo lokomba. Oku kwenza i-CMC isetyenziswe ngokubanzi kwiindawo ezingqongileyo ezigqithisileyo ezinje ngamaqula anzulu, amaqula obushushu obuphezulu, kunye nokugrumba ulwandle.
6. Ukhuseleko lokusingqongileyo
Njengemathiriyeli yendalo yepolymer, i-CMC iyabola kwaye inobuhlobo nokusingqongileyo. Xa kuthelekiswa nezinye izinto zokwenziwa kwepolymer tackifiers, iCMC inomsebenzi obalaseleyo wokusingqongileyo kwaye ihlangabezana neemfuno zoshishino lwangoku lwepetroleum kukhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo.
I-Carboxymethylcellulose (i-CMC) idlala iindima ezahlukeneyo njenge-agent-eyandisa i-viscosity kwi-drilling fluids. Iphucula kakhulu ukusebenza kolwelo lokomba kwaye iqinisekisa inkqubela phambili egudileyo yenkqubo yokomba ngokunyusa i-viscosity kunye ne-shear dilution, ukuphucula i-rheology, ukuphucula umgangatho wekeyiki yodaka, ukulawula ukulahleka kolwelo, ubushushu kunye nokuxhathisa ityuwa, kunye nokukhuselwa kwendalo. Ukusetyenziswa kwe-CMC akuphuculi nje kuphela ukusebenza kakuhle kokomba kunye nokhuseleko, kodwa kunciphisa impembelelo yokusingqongileyo. Yinto efunekayo kwaye ibalulekile kulwelo lokomba.
