Carboxymethyl cellulose (CMC) i polymer inonyungudika nemvura inotorwa kubva ku cellulose, inowanzoshandiswa mumaindasitiri akasiyana siyana pakukora, kudzikamisa, uye emulsifying zvivakwa. High viscosity CMC (CMC-HV) kunyanya ine yakasarudzika hunhu inoita kuti ive yakakosha mumashandisirwo ane chekuita nepetroleum.
1. Kemikari Mamiriro uye Kuumbwa
CMC inogadzirwa nekemikari shanduko ye cellulose, yakasikwa polymer inowanikwa muchirimwa sero madziro. Maitiro acho anosanganisira kuunzwa kwemapoka ecarboxymethyl (-CH2-COOH) mumusana we cellulose, izvo zvinoita kuti cellulose inyungudika mumvura. Iyo dhigirii yekutsiva (DS), iyo inoreva huwandu hweavhareji yemapoka ecarboxymethyl pane anhydroglucose unit mu cellulose molecule, inokanganisa zvakanyanya zvimiro zveCMC. Petroleum giredhi yakakwira viscosity CMC kazhinji ine yakakwira DS, inosimudzira kunyungudika kwemvura uye viscosity.
2. High Viscosity
Iyo inotsanangura hunhu hweCMC-HV ndeye yakakwirira viscosity kana yakanyungudika mumvura. Viscosity chiyero chekuramba kwemvura kuyerera, uye yakakwirira viscosity CMC inoumba gobvu, senge gel-semhinduro kunyangwe pakadzika. Ichi chivakwa chakakosha mukushandisa petroleum uko CMC-HV inoshandiswa kugadzirisa rheological zvimiro zvemvura yekuchera uye mamwe maumbirwo. Iyo yakakwira viscosity inovimbisa kumiswa kunoshanda kwezvakaoma, mafuta ari nani, uye kugadzikana kwakagadziridzwa kwedhaka rekuchera.
3. Kunyungudika kwemvura
CMC-HV inonyungudika zvakanyanya mumvura, chinova chinhu chikuru chinodiwa pakushandiswa kwayo muindasitiri yepetroleum. Kana yawedzerwa kumvura-based formulations, inokurumidza hydrates uye inonyunguduka, ichigadzira homogeneous solution. Kunyungudika uku kwakakosha pakugadzirira uye kushandisa zvinwiwa zvekuchera, simende slurries, uye kupera kwemvura mukushanda kwepetroleum.
4. Thermal Kugadzikana
Kushanda kwePetroleum kunowanzo sanganisira nzvimbo dzekupisa, uye kugadzikana kwekupisa kweCMC-HV kwakakosha. Iri giredhi reCMC rakagadzirirwa kuchengetedza viscosity uye kushanda kwayo pasi petembiricha yakakwira, kazhinji inosvika 150 ° C (302 ° F). Uku kugadzikana kwekupisa kunovimbisa kushanda kwakafanana mukuchera kwepamusoro-tembiricha uye maitiro ekugadzira, kudzivirira kuderedzwa uye kurasikirwa kwezvivakwa.
5. pH Kugadzikana
CMC-HV inoratidza kugadzikana kwakanaka pahupamhi hwepH, kazhinji kubva 4 kusvika 11. Uku kugadzikana kwepH kwakakosha nekuti zvinwiwa zvekuchera uye mamwe maumbirwo ane chekuita nepetroleum anogona kusangana nepH mamiriro akasiyana. Kuchengeta viscosity uye kuita munzvimbo dzakasiyana pH kunovimbisa kushanda uye kuvimbika kweCMC-HV mumamiriro akasiyana ekushanda.
6. Kushivirira kwemunyu
Mukushandisa petroleum, zvinwiwa zvinowanzosangana nemunyu wakasiyana-siyana uye electrolytes. CMC-HV yakagadzirirwa kushivirira nharaunda dzakadai, kuchengetedza viscosity yayo uye inoshanda zvinhu pamberi pemunyu. Uku kushivirira kwemunyu kunonyanya kubatsira mukuchera kumahombekombe uye kumwe kuvhiya uko mamiriro esaline akapararira.
7. Filtration Control
Rimwe remabasa akakosha eCMC-HV mukuchera zvinwiwa kudzora kurasikirwa kwemvura, inozivikanwawo sefiltration control. Kana ichishandiswa mukuchera madhaka, CMC-HV inobatsira kuumba keke rakatetepa, risingapindiki resefa pamadziro echibhorani, kudzivirira kurasikirwa kwemvura yakawandisa mukuumbwa. Iyi filtration control yakakosha pakuchengetedza wellbore kugadzikana uye kudzivirira kukuvara kwekuumbwa.
8. Biodegradability uye Environmental Impact
Sesarudzo inoziva kwezvakatipoteredza, CMC-HV inoodza uye inotorwa kubva kune zvinogonekazve zviwanikwa. Iyo biodegradability inoreva kuti inoputsika zvechisikigo nekufamba kwenguva, ichideredza kukanganiswa kwezvakatipoteredza kana ichienzaniswa nemapolymer ekugadzira. Hunhu uhwu huri kuramba huchikosha sezvo indasitiri yepetroleum inotarisa pakuchengetedza uye kuderedza tsoka dzezvakatipoteredza.
9. Kuenderana nemamwe maAdditives
CMC-HV inowanzo shandiswa pamwe chete nezvimwe zvinowedzera mumvura yekuchera uye mamwe maumbirwo epetroleum. Kuenderana kwayo nemakemikari akasiyana siyana, senge xanthan chingamu, guar gum, uye synthetic polymers, inobvumira kugadziridzwa kwezvivakwa zvemvura kuti isangane nezvinodiwa zvekushanda. Izvi zvakasiyana-siyana zvinowedzera kushanda uye kushanda kwemvura yekuchera.
10. Lubricity
Mumabasa ekuchera, kuderedza kukweshana pakati pechibhorani nechibhorani kwakakosha pakuchera nemazvo uye kuderedza kusakara. CMC-HV inobatsira kuomarara kwemvura yekuchera, kuderedza torque uye kudhonza, nekuvandudza kugona kwese kwemaitiro ekuchera. Lubricity iyi inobatsirawo mukuwedzera hupenyu hwemidziyo yekuchera.
11. Kumiswa uye Kugadzikana
Iko kugona kumisa uye kudzikamisa zvimisikidzo mumvura yekuchera kwakakosha kudzivirira kugadzika uye kuve nechokwadi cheunifomu zvivakwa mukati memvura yese. CMC-HV inopa yakanakisa kumiswa kugona, kuchengetedza uremu zvinhu, kucheka, uye zvimwe zvionda zvakagoverwa zvakaenzana. Kudzikama uku kwakakosha pakuchengetedza zvimiro zvemvura inodhirowa uye kudzivirira nyaya dzekushanda.
12. Kushandisa-Yakananga Benefits
Drilling Fluids: Muzvinwiwa zvekuchera, CMC-HV inosimudzira viscosity, inodzora kurasikirwa kwemvura, inodzikamisa chibhorani, uye inopa mafuta. Zvimiro zvaro zvinogonesa mashandiro ekuchera, kuderedza kukanganiswa kwezvakatipoteredza, uye kunatsiridza kuita kwese kweiyo yekuchera fluid system.
Kupedzisa Fluids: Mukupedza zvinwiwa, CMC-HV inoshandiswa kudzora kurasikirwa kwemvura, kudzikamisa tsime, uye kuve nechokwadi chekuvimbika kwekupedzisa. Kugadzikana kwayo kwekushisa uye kuwirirana nezvimwe zvinowedzera zvinoita kuti zvive zvakakodzera kushandiswa mumhepo yepamusoro-soro, matsime akakwirira.
Cementing Operations: Mune simende slurries, CMC-HV inoita seviscosifier uye fluid kurasikirwa control agent. Iyo inobatsira mukuzadzisa inodiwa rheological zvimiro zvesimende slurry, kuve nechokwadi chekuiswa kwakakodzera uye seti yesimende, nekudzivirira kutama kwegasi uye kurasikirwa kwemvura.
Petroleum giredhi yakakwira viscosity CMC (CMC-HV) inogoneka uye yakakosha polymer muindasitiri yepetroleum. Hunhu hwayo hwakasiyana, hunosanganisira yakakwira viscosity, kunyungudika kwemvura, kudziya uye pH kugadzikana, kushivirira munyu, kudzora kusefa, biodegradability, uye kuenderana nezvimwe zvinowedzera, inoita kuti ive yakakosha kune akasiyana petroleum-ane chekuita nekushandisa. Kubva pakuchera zvinwiwa kusvika pakupedzwa nekusimbisa mashandiro, CMC-HV inosimudzira mashandiro, kugona, uye kuchengetedzwa kwezvakatipoteredza kwekuchera peturu uye maitiro ekugadzira. Sezvo indasitiri iri kuramba ichishanduka, kudiwa kwekuita kwepamusoro-soro, zvekuwedzera zvine hushamwari kwezvakatipoteredza seCMC-HV zvichangowedzera, zvichisimbisa basa rayo rakakosha mukushanda kwemazuva ano peturu.
