Tuam Tshoj thawj zaug Offshore Thermal Recovery Cheeb Tsam Ua Tau Tshaj 1.2 lab Tons Cov Roj Crude

Cov roj crude ntau lawm ntawm thermal rov qab nyob rau yav qab teb cheeb tsam ntawm Nanpu 35-2 Oilfield, Tuam Tshoj tus thawj offshore thermal rov qab kuaj cheeb tsam, tau tshaj 1.2 lab tons. Raws li cov lus ceeb toom, Nanpu 35-2 Oilfield yog ib qho ntawm cov roj av hnyav uas tau muab tso rau hauv kev txhim kho ua ntej hauv hiav txwv Bohai. Lub viscosity ntawm cov roj crude nyob rau yav qab teb cheeb tsam ntawm kev tsim yog 400 mus rau 700 millipascals, thiab lub peev xwm ntau lawm thiab rov qab tus nqi ntawm conventionally tsim cov roj qhov dej yog tsawg heev. Yog tias qhov kev tsim kho cua sov tsuas yog siv rau hauv thaj tsam yav qab teb ntawm cov roj av, nws yog ib qho yooj yim uas yuav ua rau muaj teeb meem thaum tshav kub kub poob vim muaj cov yam ntxwv xws li qhov sib sib zog nqus faus ntawm cov roj crude thiab nyias reservoirs nyob rau hauv cheeb tsam, uas ua rau cov thermal rov qab tsis zoo. Txhawm rau txhawb nqa "kev txav mus los" ntawm cov roj hnyav, kev tsim khoom thiab cov neeg ua haujlwm tshawb fawb tshawb fawb txuas ntxiv mus rau kev tshawb fawb txog kev tshawb fawb, ua cov kev sim ntawm ntau lub ntsiab lus thermal fluid throughput thiab chav tsav kev loj hlob, optimize qhov tsim ntawm ntau lub ntsiab thermal. Cov kua dej los ntawm kev siv thev naus laus zis ntawm "dej kub + nitrogen + carbon dioxide", thiab tsim cov txiaj ntsig zoo ntawm "viscosity txo + zog nce", yog li txhim kho fluidity ntawm cov roj hnyav thiab ua rau cov roj hnyav. "txav" ua tiav. Tam sim no, cov khoom siv hluav taws xob ntau lub tshuab hluav taws xob los ntawm kev siv tshuab tau pab ntau tshaj 800, 000 tons roj crude rau Nanpu 35-2 oilfield, zoo pab kev txhim kho cov roj hnyav nyob rau sab qab teb ntawm ​​lub Nanpu 35-2 oilfield. Tsis tas li ntawd, cov neeg ua haujlwm tsim khoom thiab kev tshawb fawb tau siv cov tswv yim tswj kev khiav dej num raws li "qhov dej", thiab txuas ntxiv ua kom cov thermal rov qab ua ke nrog cov hlua khi thiab kub kub ntsaws cov txheej txheem tshiab thiab kev siv daim ntawv thov, kom cov roj crude tsav los ntawm chav thiab "khiav" nyob rau hauv cov lus qhia sib txawv tuaj yeem ntws zoo dua thiab sib npaug. Nws tau tshaj tawm tias qhov kev tswj hwm kev khiav dej num tau siv ze li ntawm 30 qhov dej, uas tau txhim kho cov roj av rov qab thiab txhawb nqa qhov "nyiaj ntsuab" tas li ntawm Bohai cov roj hnyav.
