Kev siv PAC hauv cov roj drilling
Txheej txheem cej luam
Poly anionic cellulose, abbreviated li PAC, yog cov dej-soluble cellulose ether derivative uas tsim los ntawm kev hloov tshuaj ntawm natural cellulose, yog ib qho tseem ceeb dej-soluble cellulose ether, yog ib tug dawb los yog daj hmoov, tsis muaj tshuaj lom, saj tsis qab. Nws tuaj yeem yaj hauv dej, muaj kev ruaj ntseg zoo thiab ntsev, thiab muaj zog tiv thaiv kab mob. Cov kua av nkos formulated nrog cov khoom no muaj cov dej tsis zoo, inhibition thiab kub tsis kam. Nws yog dav siv nyob rau hauv cov roj drilling, tshwj xeeb tshaj yog cov dej ntsev qhov dej thiab offshore roj drilling.
PAC nta
Nws belongs rau ionic cellulose ether nrog siab purity, qib siab ntawm kev hloov pauv thiab kev faib tawm ntawm cov khoom hloov pauv. Nws tuaj yeem siv los ua tus neeg sawv cev thickening, rheology hloov kho, tus neeg saib xyuas dej poob thiab lwm yam.
1.Suitable siv nyob rau hauv tej av nkos los ntawm cov dej tshiab rau saturated dej ntsev.
2.Low viscosity PAC tuaj yeem txo qhov kev pom tsis zoo thiab tsis ua rau cov kab mob ua rau lub cev ua kom zoo.
3.High viscosity PAC muaj siab slurry tawm los thiab pom tseeb cov nyhuv ntawm txo cov dej poob. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov khoom siv qis-theem slurry thiab tsis yog-khoom-theem ntsev dej slurry.
4.Cov av nkos formulated nrog PAC inhibit av nplaum thiab shale dispersion thiab nthuav nyob rau hauv heev saline nruab nrab, yog li cia zoo phab ntsa paug tswj.
5.Excellent av nkos drilling thiab workover kua, npaum fracturing kua.
PACDaim ntawv thov
1.PAC daim ntawv thov hauv cov kua dej drilling.
PAC yog qhov zoo tagnrho rau kev siv los ua tus inhibitor thiab dej txo tus neeg sawv cev. PAC tsim cov av nkos cuam tshuam cov av nplaum thiab shale dispersion thiab o nyob rau hauv siab ntsev nruab nrab, yog li tso cai rau cov kab mob hauv phab ntsa kom tswj tau zoo.
2. PAC daim ntawv thov hauv cov kua dej ua haujlwm.
Cov kua dej ua haujlwm zoo tsim nrog PAC yog cov khoom qis, uas tsis thaiv cov permeability ntawm cov khoom tsim nrog cov khib nyiab thiab tsis ua rau cov khoom tsim; thiab muaj qhov poob dej tsawg, uas txo cov dej nkag mus rau qhov tsim tawm.
Tiv thaiv cov khoom tsim los ntawm kev puas tsuaj mus tas li.
Muaj peev xwm los ntxuav boreholes, kev saib xyuas ntawm boreholes yog txo.
Nws muaj peev xwm tiv taus dej thiab sediment infiltration thiab tsis tshua muaj foams.
Nws tuaj yeem khaws cia lossis hloov pauv ntawm qhov dej thiab qhov dej, tus nqi qis dua li cov dej ua haujlwm hauv av.
3. PAC daim ntawv thov nyob rau hauv cov kua fracturing.
Cov kua fracturing formulated nrog PAC muaj kev ua tau zoo dissolution. Nws yog ib qho yooj yim mus use, thiab nws muaj ceev ceev gel tsim ceev thiab muaj zog xuab zeb nqa peev xwm. Nws tuaj yeem siv rau hauv cov txheej txheem osmotic siab, thiab nws cov nyhuv fracturing zoo heev.
