--- MSG / AMC / SNAPG.
Nyob rau hauv cov xyoo tas los no, SINOPEC tau maj mam tsim cov qhov dej tob, ultra-sib sib zog nqus qhov dej, kev taw qhia qhov dej, kab rov tav qhov dej, qhov chaw txav chaw loj, qhov kub ntawm lub qhov ntev qhib lub qhov dej thiab lwm yam dej nrog cov nyuaj qhov yuav tsum tau nce ntxiv. Cov ntaub ntawv nyoos ntawm ECO-phooj ywg kev kho mob tshuaj ntxiv tam sim no muaj qee qhov teeb meem xws li kub tsis kam, kev ua haujlwm qis, thiab kev hloov kho ib qho. Yog li, cov khoom lag luam no tsis tuaj yeem ua tau raws li cov cuab yeej xav tau zoo.
SINOPEC Zhongyuan Peotroleum Engineering Lub Tuam Txhab Drilling Engineering Technical Institute tau tsim peb qhov kev ua tau zoo los ntawm kev siv zog ua haujlwm R& D nyob rau xyoo ntev.MSG / AMC / SNAPG.
Txij li thaum tsim los pab cov pab pawg neeg tshaj tawm txoj haujlwm tshiab nyob ib puag ncig peb tes num hauv 2017, pab pawg tau ua cov kev tshawb fawb tshaj lij txog peb yam ntawm kev ua kua dej ua kom zoo. Qhov ntawd suav nrog MSG> Los tiv thaiv kub viscosity& kev ua haujlwm nce zuj zus; AMC> Siab kub& Siab ntsev resistant pom tswj;
SNAPG> High kub resistant thiab mas inhibitive. Lawv tau sim cov yam ntxwv ntawm peb lub molecules muaj xws li: Chitosan, Scleroglucan, thiab Alkyl Glycosides, thiab sib xyaw lawv nrog ntau txoj hauv kev xws li Alkalization, Polycondensation, Carboxylation, Amination, thiab Graft Copolymerization.
Piv nrog rau yav dhau los drilling kua tshuaj kho ntxiv, Nws tsim nyog hais tias cov khoom siv no tuaj yeem daws cov teeb meem xws li siab kub, ntu kab rov tav ntev, txheej ntsev-gypsum, muaj zog shale-shale thiab lwm cov qauv tsim, xws li downhole xuab zeb, ntsev-gypsum kev ua qias tuaj, thiab kev nyab xeeb tsis zoo. Nws tseem tuaj yeem ua kom nce ROP, luv lub voj voog drilling, txo tus nqi drilling, thiab ua tiav ntsuab, nyab xeeb thiab siv yooj yim drilling., Nws lub tshuab tau dhau los ua tus thawj coj thoob ntiaj teb.
Daim ntawv thov cov ntaub ntawv tshawb>
Xyoo 2020, hauv qhov dej zoo TK6131, nws qhov kev tsim kho tau zoo hauv Tahe Oilfield, cov haujlwm tsis sib xws yog qhov loj dua thaum tho ntawm 660.4mm. Yog tias qhov dej ntws ua kua viscosity tsis tuaj yeem sib phim, nws yuav yooj yim ua rau pob zeb txiav kom xau thiab khaws. Nws yuav ua rau cov yeeb nkab daig thiab torque thiab pob zeb txiav kev sib hais haum. Cov ntaub ntawv muaj kev vam meej ntawm kev tiv thaiv kev tiv thaiv kev kub siab ua tau zoo ua kom tus neeg sawv cev tau txhim kho txoj kev sib tw ua kua drilling. Tib lub sijhawm, nws muaj lub peev xwm zoo nqa lub pob zeb thiab xuab zeb. Nws tseem tuaj yeem lav qhov huv ntawm lub Wellbore thiab zam qhov tshwm sim ntawm cov xwm txheej nyuaj xws li xuab zeb xuab zeb thiab daig tsoo.
Hloov Hard Dextran: MSG, Hloov Khoos Chitosan AMC; Hloov Kho Alkyl Glycoside SNAPG thiab lwm Tus Hloov Kho Biomass drilling kua tshuaj yog ib puag ncig zoo thiab raug nqi. Lawv tuaj yeem daws cov teeb meem ntawm qhov dej tob ntws ntws tawm qhov kev tswj tus qauv, tswj dej tsis xwm yeem, ua kom zoo li qub, thiab lwm yam.
Txog tam sim no, cov khoom lag luam no tau siv hauv 10 qhov dej nyob hauv Suav teb thiab lwm lub teb chaws, suav nrog Kev Nyab Xeeb siab kub tsis zoo hauv qhov dej, Kev tshawb nrhiav qhov dej, thiab Directional qhov dej, thiab tau txais txiaj ntsig zoo. Pawg Thawj Coj ntawm Ministry of Science thiab Technology ntawm Sinopec Pawg Tuam Txhab ntseeg tau hais tias Modified biomass series cov khoom lag luam thiab cov ntawv pov thawj ntau lawm yog thawj R& D thiab tuaj yeem mus txog theem thoob ntiaj teb.
