Carboxymethyl Cellulose (CMC) ke ntho e eketsang viscosity e sebelisoang haholo marong a ho cheka 'me e na le ho qhibiliha ha metsi hantle le phello e teteaneng.
1. Ntlafatsa viscosity le thepa ea ho kuta moriri
CMC e etsa tharollo e nang le viscosity e phahameng ha e qhibiliha ka metsing. Liketane tsa eona tsa limolek'hule li atoloha ka metsing, 'me li eketsa ho hohlana ha mokelikeli ka hare ho eona 'me ka hona ho eketsa ponahalo ea mokelikeli o chekang. Viscosity e phahameng e thusa ho jara le ho emisa li-cuttings nakong ea ho cheka le ho thibela li-cuttings ho bokellana ka tlase ho seliba. Ho phaella moo, litharollo tsa CMC li bonts'a thepa ea ho kuta, ke hore, viscosity e fokotseha ka litekanyetso tse phahameng tsa ho kuta, e thusang hore mokelikeli oa ho cheka o phalle tlas'a matla a phahameng a ho kuta (joaloka haufi le drill bit) ha o ntse o le maemong a tlaase (joalo ka annulus). ). boloka viscosity e phahameng ho emisa ka katleho li-cuttings.
2. Ntlafatsa rheology
CMC e ka ntlafatsa haholo rheology ea maro a ho cheka. Rheology e bua ka deformation le phallo litšobotsi tsa mokelikeli tlas'a ketso ea matla a ka ntle. Nakong ea ts'ebetso ea ho cheka, rheology e ntle e ka etsa bonnete ba hore mokelikeli oa ho phunya o na le ts'ebetso e tsitsitseng tlas'a khatello e fapaneng le maemo a mocheso. CMC e ntlafatsa bokhoni ba ho cheka le polokeho ka ho fetola sebopeho sa mokelikeli oa ho cheka hore o be le rheology e nepahetseng.
3. Ntlafatsa boleng ba kuku ea seretse
Ho kenyelletsa CMC ho mokelikeli oa ho cheka ho ka ntlafatsa boleng ba kuku ea seretse. Kaka ea seretse ke filimi e tšesaane e entsoeng ka ho cheka mokelikeli leboteng la ho phunya, e phethang karolo ea ho koala li-pores, ho tsitsisa lerako la seliba le ho thibela tahlehelo ea mokelikeli oa ho phunya. CMC e ka theha kuku e teteaneng le e thata ea seretse, ea fokotsa ho kenella le ho lahleheloa ke filthara ea kuku ea seretse, ka hona ho ntlafatsa botsitso ba lebota la seliba le ho thibela ho putlama hantle le ho lutla.
4. Laola tahlehelo ea sefe
Tahlehelo ea mokelikeli e bolela ho kenella ha karolo ea mokelikeli mokelikeli oa ho phunya ka har'a li-pores tsa sebopeho. Ho lahleheloa ke metsi a mangata ho ka lebisa ho se tsitseng ha lebota la seliba esita le ho phatloha. CMC e laola ka katleho tahlehelo ea mokelikeli ka ho etsa tharollo ea viscous mokelikeli oa ho cheka, ho eketsa viscosity ea mokelikeli le ho fokotsa sekhahla sa ho kenella ha mokelikeli. Ho phaella moo, kaka ea boleng bo phahameng ea seretse e entsoeng ke CMC leboteng la seliba e thibela ho lahleheloa ke metsi.
5. Mocheso le ho hanyetsa letsoai
CMC e na le mocheso o motle le ho hanyetsa letsoai 'me e loketse maemo a fapaneng a ho thehoa a rarahaneng. Libakeng tse nang le mocheso o phahameng le letsoai le lengata, CMC e ntse e ka boloka phello ea eona ea ho eketsa viscosity ho netefatsa ts'ebetso e tsitsitseng ea maro a ho cheka. Sena se etsa hore CMC e sebelisoe haholo libakeng tse feteletseng tse kang liliba tse tebileng, liliba tse nang le mocheso o phahameng le ho cheka leoatleng.
6. Tšireletso ea tikoloho
E le thepa ea tlhaho ea polymer, CMC e ka senyeha habonolo ebile e na le botsoalle ba tikoloho. Ha ho bapisoa le li-tackifiers tsa maiketsetso tsa polymer, CMC e na le ts'ebetso e phahameng ea tikoloho mme e fihlela litlhoko tsa indasteri ea sejoale-joale ea peterole bakeng sa ts'ireletso ea tikoloho le nts'etsopele e tsitsitseng.
Carboxymethylcellulose (CMC) e na le likarolo tse fapaneng e le sesebelisoa se eketsang viscosity ho maro a ho cheka. E ntlafatsa haholo ts'ebetso ea maro a ho cheka le ho netefatsa tsoelo-pele e ntle ea ts'ebetso ea ho cheka ka ho eketsa viscosity le ho hlapolla ha shear, ho matlafatsa rheology, ho ntlafatsa boleng ba kuku ea seretse, ho laola tahlehelo ea mokelikeli, mocheso le letsoai le ts'ireletso ea tikoloho. Tšebeliso ea CMC ha e ntlafatse bokhoni ba ho cheka le polokeho feela, empa hape e fokotsa tšusumetso ea tikoloho. Ke karolo ea bohlokoa le ea bohlokoa marong a ho cheka.
