ICarboxymethyl cellulose (CMC) yipolymer ephezulu yemolekyuli esetyenziswa kakhulu ekugrumbeni ulwelo oluneempawu ezilungileyo zerheological kunye nokuzinza. Iyi-cellulose eguquliweyo, eyenziwa ikakhulu ngokuphendula i-cellulose kunye ne-chloroacetic acid. Ngenxa yokusebenza kwayo okugqwesileyo, i-CMC isetyenziswe ngokubanzi kwiindawo ezininzi ezifana nokugrumba ioli, imigodi, ukwakhiwa kunye neshishini lokutya.
1. Iipropati ze-CMC
I-Carboxymethyl cellulose ngumgubo omhlophe ukuya kumthubi okhanyayo owenza isisombululo se-colloidal esicacileyo xa inyibilikiswa emanzini. Ubume bayo beekhemikhali buqukethe amaqela e-carboxymethyl, okwenza ukuba ibe ne-hydrophilicity enhle kunye ne-lubricity. Ukongeza, i-viscosity ye-CMC inokulawulwa ngokulungelelanisa ubunzima bayo be-molecular kunye nokugxila, okwenza ukusetyenziswa kwayo kwi-drilling fluids ibe bhetyebhetye kakhulu.
2. Indima kulwelo lokomba
Ngexesha lenkqubo yokomba, ukusebenza kolwelo lokomba kubalulekile. I-CMC idlala ezi ndima ziphambili kulwelo lokomba:
I-Thickener: I-CMC inokunyusa i-viscosity yokwemba ulwelo, ngaloo ndlela iphucula umthamo wabo wokuthwala, igcina amasuntswana aqinileyo axhonyiweyo, kunye nokuthintela intlenga.
I-Rheology modifier: Ngokuhlengahlengisa iimpawu ze-rheological zolwelo lokomba, i-CMC inokuphucula ubumanzi bayo ukuze ikwazi ukugcina ubumanzi obulungileyo phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu.
I-agent yeplagi: Amasuntswana e-CMC angazalisa iintanda zamatye, anciphise ngokufanelekileyo ilahleko yolwelo kunye nokuphucula ukusebenza kakuhle kokomba.
I-Lubricant: Ukongezwa kwe-CMC kunokunciphisa ingxabano phakathi kwe-drill bit kunye nodonga lomthombo, ukunciphisa ukuguga kunye nokunyusa isantya sokomba.
3. Izinto eziluncedo zeCMC
Ukusebenzisa i-carboxymethyl cellulose njengesongezo solwelo lokomba kunezi nzuzo zilandelayo:
Ikhuseleke ngokusingqongileyo: I-CMC sisixhobo sepolymer sendalo esinokonakala okuhle kwe-biodegradability kunye nefuthe elincinci kokusingqongileyo.
Ukusebenza kweendleko: Xa kuthelekiswa nezinye iipholima zokwenziwa, i-CMC inexabiso eliphantsi, ukusebenza okugqwesileyo kunye nokusebenza kakuhle kweendleko.
Iqondo lobushushu kunye nokuguquguquka kwetyuwa: I-CMC isenokugcina ukusebenza okuzinzileyo kubushushu obuphezulu kunye neendawo ezinetyuwa ephezulu kwaye iqhelane neemeko ezahlukeneyo zejoloji.
4. Imizekelo yokusetyenziswa
Kwizicelo zokwenyani, iinkampani ezininzi ze-oyile ziye zafaka ngempumelelo i-CMC kwiiprojekthi ezahlukeneyo zokomba. Umzekelo, kwezinye iqondo lobushushu eliphezulu kunye noxinzelelo oluphezulu amaqula, ukongeza isixa esifanelekileyo CMC inokulawula ngempumelelo rheology yodaka kunye nokuqinisekisa ukubhola egudileyo. Ukongeza, kwezinye iindlela ezintsonkothileyo, ukusebenzisa i-CMC njengesixhobo sokuplaga kunokunciphisa kakhulu ilahleko yolwelo kunye nokuphucula ukusebenza kakuhle kokomba.
5. Izilumkiso
Nangona i-CMC ineenzuzo ezininzi, ezi ngongoma zilandelayo kufuneka ziqatshelwe ngexesha lokusetyenziswa:
Umlinganiselo: Lungisa isixa se-CMC esongeziweyo ngokweemeko zokwenyani. Ukusetyenziswa kakhulu kunokukhokelela ekunciphiseni ulwelo.
Iimeko zokugcina: Kufuneka igcinwe kwindawo eyomileyo nepholileyo ukuphepha ukufuma okuchaphazela ukusebenza.
Ukuxuba ngokulinganayo: Xa ulungiselela ulwelo lokomba, qinisekisa ukuba iCMC inyibilike ngokupheleleyo ukunqanda ukudityaniswa kwamasuntswana.
Ukusetyenziswa kwe-carboxymethyl cellulose kwi-drilling fluid akugcini nje ukuphucula ukusebenza kakuhle kunye nokunciphisa iindleko, kodwa kukhuthaza ukuphuhliswa kobuchwephesha bokukhusela indalo ukuya kwinqanaba elithile. Ngokuqhubela phambili kwenzululwazi nobuchwepheshe, umda wokusetyenziswa kwe-CMC uya kwandiswa ngakumbi, kwaye sijonge phambili ekudlaleni indima enkulu kwiiprojekthi zokomba zexesha elizayo.
