Chii kushandiswa kwe cellulose mukuchera madhaka

Cellulose, kabhohaidhireti yakaoma inowanikwa mumadziro emiti, inoita basa rakakosha mumaindasitiri akasiyana siyana, kusanganisira chikamu cheoiri negesi. Mukuchera madhaka, cellulose inoshandisa zvinangwa zvakawanda nekuda kweiyo yakasarudzika zvimiro uye maitiro.

Kuchera madhaka, kunozivikanwawo semvura yekuchera, chinhu chakakosha mukuchera mafuta uye gasi matsime. Inoshanda akati wandei akakosha mabasa, anosanganisira kutonhora nekuzora dhiri, kutakura matombo ekucheka kumusoro, kuchengetedza kugadzikana kwetsime, nekudzivirira kukuvara kwekugadzira. Kuzadzisa mabasa aya nemazvo, madhaka ekuchera anofanirwa kuve nezvimwe zvivakwa zvakaita seviscosity, kudzora kurasikirwa kwemvura, kumiswa kwezvakaoma, uye kuenderana nemamiriro ekudzika.

Celluloseinowanzoshandiswa mukuchera madhaka maumbirwo sechinhu chekutanga chekuwedzera nekuda kweiyo yakasarudzika rheological maitiro uye kuita zvakasiyana. Rimwe remabasa makuru e cellulose mukuchera madhaka kupa viscosity uye rheological control. Viscosity chiyero chekuramba kwemvura kuyerera, uye yakakosha mukuchengeta yaunoda kuyerera zvinhu zvekuchera madhaka. Nekuwedzera cellulose, viscosity yematope inogona kugadziriswa kuti isangane nezvinodiwa zvekushanda kwekuchera. Izvi zvinonyanya kukosha pakudzora chiyero chekupinda, kudzivirira kurasikirwa kwemvura mukuumbwa, uye kutakura drill cuttings kumusoro.

cellulose inoshanda seviscosifier uye fluid kurasikirwa control agent panguva imwe chete. Se viscosifier, inobatsira kumisa uye kutakura zvibooreso zvakachekwa kumusoro, zvichidzivirira kuti zvisagadzikane uye zviungane pazasi pegomba. Izvi zvinova nechokwadi chekushanda kwakanaka kwekuchera uye kuderedza njodzi yezviitiko zvepombi dzakanamira. Pamusoro pezvo, cellulose inoumba keke rakatetepa, risingapindiki resefa pamadziro etsime, rinobatsira kudzora kurasikirwa kwemvura mukuumbwa. Izvi zvakakosha pakuchengetedza kugadzikana kwetsime uye kudzivirira kukuvadzwa kwekuumbwa kunokonzerwa nekupinda kwemvura.

Pamusoro peiyo rheological uye fluid kurasikirwa kwekudzora zvivakwa, cellulose inopawo mabhenefiti ezvakatipoteredza mukuchera madhaka maumbirwo. Kusiyana nezvinowedzerwa zvekugadzira, cellulose inoodza uye ine hushamwari kwezvakatipoteredza, zvichiita kuti ive sarudzo inosarudzika yekucheresa nharaunda. Iyo biodegradability inova nechokwadi chekuti inoputsika zvechisikigo nekufamba kwenguva, ichideredza kukanganiswa kwezvakatipoteredza kwemabasa ekuchera.

Cellulose inogona kuiswa mukuchera madhaka maumbirwo nenzira dzakasiyana siyana, kusanganisira poda cellulose, cellulose fibers, uye cellulose zvinobuda senge.Carboxymethyl cellulose (CMC)uyehydroxyethyl cellulose (HEC). Imwe neimwe fomu inopa mabhenefiti chaiwo uye mashandiro zvichienderana nezvinodiwa zvekuchera.

Powdered cellulose inowanzoshandiswa seyekutanga viscosifier uye yekurasikirwa kwemvura yekudzora mumiriri mumvura-yakavakirwa madhaka masisitimu. Inoparadzirwa zviri nyore mumvura uye inoratidza yakanakisa kumiswa zvivakwa, zvichiita kuti ive yakanaka kutakura drill cuttings kumusoro.

Kune rumwe rutivi, macellulose fibers akareba uye ane fibrous kupfuura cellulose yehupfu. Iyo inowanzoshandiswa muhuremu hwedhaka masisitimu, uko yakanyanya-density yekuchera mvura inodiwa kudzora kuumbwa kumanikidza. Cellulose fibers inobatsira kusimudzira kutendeseka kwedhaka, kunatsiridza gomba rekuchenesa, uye kuderedza torque uye kudhonza panguva yekuchera.

Cellulose derivatives akadaiCMCuyeHECikemikari yakagadziridzwa mafomu e cellulose ayo anopa yakawedzera kuita zvivakwa. Iwo anowanzo shandiswa muhunyanzvi hwekuchera madhaka maapplication uko chaiko kwekuita zvinodiwa kunoda kusangana. Semuyenzaniso, CMC inoshandiswa zvakanyanya seshale inhibitor uye fluid kurasikirwa control agent mumvura-based matope masisitimu, nepo HEC inoshandiswa se rheology modifier uye filtration control agent muoiri-based mud system.

cellulose inoita basa rakakosha mukuchera madhaka maumbirwo nekuda kwezvakasiyana zvivakwa uye kuita zvakasiyana. Kubva pakupa viscosity uye rheological control kusvika pakunatsiridza kurasikirwa kwemvura uye kuchengetedza kwezvakatipoteredza, cellulose inopa akawanda mabhenefiti mumabasa ekuchera. Sezvo indasitiri yeoiri negasi iri kuramba ichishanduka, kudiwa kweanoshanda uye ane hushamwari kuchera madhaka mhinduro kunotarisirwa kuwedzera, zvichiwedzera kuratidza kukosha kweselulosi sechinhu chakakosha chekuwedzera mukudhirowa kwemvura.
