Carboxymethyl Cellulose (CMC) ndeye viscosity-inowedzera mumiriri inoshandiswa zvakanyanya mukuchera zvinwiwa uye ine yakanaka kunyungudika kwemvura uye kukora mhedzisiro.
1. Kuvandudza viscosity uye shear kuonda zvivakwa
CMC inoumba mhinduro ine high viscosity kana yakanyungudutswa mumvura. Cheni dzayo dzemamorekuru dzinowedzera mumvura, dzichiwedzera kukweshera kwemukati kwemvura uye nekudaro kuwedzera viscosity yemvura yekuchera. High viscosity inobatsira kutakura uye kumisa cuttings panguva yekuchera uye inodzivirira kucheka kuunganidza pasi petsime. Uye zvakare, CMC mhinduro dzinoratidza shear dilution zvivakwa, ndiko kuti, viscosity inodzikira pakakwirira shear rates, iyo inobatsira kudhiraivha mvura kuyerera pasi pemasimba makuru ekugera (senge padhuze ne drill bit) panguva yakaderera shear mitengo (senge mu annulus. ) chengetedza yakakwira viscosity kuti inyatso kumisa cuttings.
2. Kuwedzera rheology
CMC inogona kuvandudza zvakanyanya rheology yekuchera mvura. Rheology inoreva deformation uye kuyerera maitiro emvura pasi pekuita kwemasimba ekunze. Munguva yekuchera, yakanaka rheology inogona kuve nechokwadi chekuti mvura yekuchera ine yakagadzikana kuita pasi pekumanikidza kwakasiyana uye tembiricha mamiriro. CMC inovandudza kuchera nekuchengetedzeka nekushandura chimiro chemvura yekuchera kuitira kuti ive yakakodzera rheology.
3. Kuvandudza dhaka cake quality
Kuwedzera CMC kune yekuchera mvura inogona kuvandudza mhando yedhaka keke. Mud cake ifirimu rakatetepa rinoumbwa nekuchera mvura pamadziro ekuchera, iyo inotamba basa rekuvhara pores, kudzikamisa madziro etsime uye kudzivirira kudonha kwemvura. CMC inogona kuumba keke yakaomeswa uye yakaoma yedhaka, kuderedza kupera uye kurasikirwa kwesefa kwekeke rematope, nekudaro ichivandudza kugadzikana kwemadziro etsime nekudzivirira kudonha nekudonha.
4. Kudzora kurasikirwa kwesefa
Kurasika kwemvura kunoreva kupinda kwechikamu chemvura mumvura yekuchera mupores yekuumba. Kurasikirwa kwemvura yakawandisa kunogona kutungamirira mukusagadzikana kwemadziro etsime uye kunyange kuputika. CMC inonyatso kudzora kurasikirwa kwemvura nekugadzira mhinduro ye viscous mumvura yekuchera, ichiwedzera viscosity yemvura uye kudzikisa pasi pekupinda kwechikamu chemvura. Uye zvakare, iyo yemhando yepamusoro keke yematope yakaumbwa neCMC pamadziro etsime inodzivirira kurasikirwa kwemvura.
5. Tembiricha uye munyu kuramba
CMC ine tembiricha yakanaka uye munyu kuramba uye inokodzera kwakasiyana kwakaoma kuumbwa mamiriro. Munzvimbo dzepamusoro-tembiricha uye nemunyu wakanyanya, CMC inogona kuramba ichichengetedza viscosity-inowedzera mhedzisiro kuti ive nechokwadi chekuita kwakagadzikana kwemvura yekuchera. Izvi zvinoita kuti CMC ishandiswe zvakanyanya munzvimbo dzakanyanyisa dzakadai sematsime akadzika, matsime ekupisa kwepamusoro, uye kuchera kwegungwa.
6. Kuchengetedza kwezvakatipoteredza
Sechisikigo chepolymer zvinhu, CMC inoodza uye ine hushamwari. Kuenzaniswa nemamwe ekugadzira polymer tackifiers, CMC ine hukuru hwekuita kwezvakatipoteredza uye inosangana nezvinodiwa zvemazuva ano petroleum indasitiri yekuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba.
Carboxymethylcellulose (CMC) inotamba mabasa akasiyana siyana seanoita viscosity-inowedzera mumiriri mumvura yekuchera. Iyo inovandudza zvakanyanya mashandiro ezvinwiwa zvekuchera uye inovimbisa kufambira mberi kwakanaka kwechibhorani nekuwedzera viscosity uye shear dilution, inosimudzira rheology, kuvandudza madhaka keke kunaka, kudzora kurasikirwa kwemvura, tembiricha uye munyu kuramba, uye kuchengetedza kwezvakatipoteredza. Kushandiswa kweCMC hakungonatsiridza kuchera nekuchengetedzeka chete, asi zvakare kunoderedza kukanganisa kwezvakatipoteredza. Icho chinhu chakakosha uye chakakosha chikamu mukuchera zvinwiwa.
