Daqing Drilling Drilling Lub Tuam Txhab No. 4 Undertakes Drilling Thiab Kev Tsim Kho Ntawm Geothermal Wells nyob rau hauv -zero Carbon- Ua qauv qhia cheeb tsam ntawm Jilin Oilfield
Oct 25, 2023
Lub caij nplooj zeeg cua yog bleak thiab txias, thiab nws yog lub caij cua sov txhua xyoo. Thaum Lub Kaum Hli 21, Ying 801 tau ua tiav los ntawm 30575 drilling pab pawg ntawm Daqing Drilling Company No. 4 tau ua tiav drilled. Lub qhov dej no yog ib qho ntawm cov cua kub hauv qhov dej hauv qhov dej uas tau muab tso rau hauv Yingtai Oil Production Cog ntawm Jilin Oilfield. Nws muab cov kev pabcuam zoo thiab muaj txiaj ntsig zoo rau Jilin Oilfield. Kev tsim kho ntawm "zero carbon" ua qauv qhia cheeb tsam yuav pab txo qis-carbon kev loj hlob ntawm Yingtai mining cheeb tsam hauv Jilin.
Cov pab pawg ntawm cov cua sov hauv qhov dej no muaj tag nrho peb qhov kev tsim kho, ib lub qhov dej rov qab los thiab ob lub qhov dej rov qab, ob qho tib si yog 241.3 hli loj boreholes. Zoo Ying 801 yog qhov kub rov qab zoo nrog qhov ua tiav qhov tob ntawm 1932 meters. Lub sijhawm drilling thib ob tsuas yog 2.92 hnub. Qhov nruab nrab txhua hnub footage yog 422 meters, uas ua rau lub tuam txhab Daqing Drilling No. 4 tau txhim kho nws lub peev xwm los tho roj, roj, dej thiab lwm yam txheej txheem tshwj xeeb, thiab tau txais txiaj ntsig zoo hauv kev drilling thiab tsim cov qhov dej tsis sib xws.
Nyob rau hauv kev pom ntawm kev tsim kho ntawm lub qhov dej loj thiab cov casing + tshuaj ntsuam ua tiav tshuab, lub tuam txhab thib plaub drilling tau tsim cov khoom siv sib koom ua ke thiab pab pawg neeg txhawb nqa los koom ua ke geological engineering thiab kev tsim kho kom ntseeg tau tias lub cev zoo. Ua ke nrog qhov yooj yim to thiab lithological yam ntxwv ntawm kev tsim, peb tog ntawm drilling, txiav, thiab taw qhia kev sib txuas lus tau zoo, siv cov khoom siv tho, cov cuab yeej tho pob qij txha, ua tiav thiab cov cuab yeej zoo, ua kom zoo dua cov cuab yeej xyaum ua ke, xyaum "Tsib Tshaj Tawm" , thiab nquag txhawb nqa "Ob Cases" "Ib qho zoo tshaj plaws, ib lub pob caus", ua tiav cov haujlwm tsim kho nrog cov khoom zoo.
"Peb yuav tsum sib txuas lus zoo nrog lub tsev tsim kho, muab kev tsim kho kom zoo ua ntej, siv cov phiaj xwm kev ua haujlwm thiab kev ntsuas nrog cov qauv siab, nce kev tsim kho kom nrawm, thiab ua tiav cov dej kub hauv qhov dej drilling kev tsim kho kom zoo," Zhu Ruichun, tus thawj coj ntawm pab pawg 30575 drilling, hais nyob rau hauv lub rooj sib tham project.
Thaum lub sij hawm tsim kho, on-site engineering technology thiab on-site tswv nruj me ntsis siv engineering thiab geological designs kom kov yeej cov teeb meem ntawm loj-loj sib sib zog nqus wellbore kev sib txhuam nyob rau hauv lub sij hawm tom qab thiab nyuaj rau kev tswj cov kev taw qhia lub ntsej muag. Lawv tau ua kom zoo dua cov khoom siv tho, saib xyuas lub qhov dej zoo txhua lub sijhawm, thiab kev tshawb fawb kwv yees qhov tob tob hauv qhov dej ua ntej. kev taw qhia, sib txuas lus kom raug cov lus qhia kev tsim kho, thiab kho qhov drilling tsis raws sijhawm; Ua tib zoo mloog zoo rau kev ruaj ntseg zoo thiab kev ua kom huv hauv qhov dej zoo, ua kom zoo dua cov qauv ntawm cov dej dihydrogen polymer system, tswj qhov ntom ntom thiab dej tsis zoo, thiab nruj me ntsis siv cov kev cai drilling kua dej thiab tswj cov dej drilling. Drilling ceev; nruj me ntsis raws li lub hauv paus ntsiab lus ntawm "ib tug centering, ob guarantees, thiab peb siab stability", thiab nruj me ntsis raws li cov txheej txheem cementing ntsuas. Raws li tus nqi ntawm lub taub hau siab, lub ntim ntim tau raug nthuav dav thiab kaw, lub hanger raug teeb tsa kom raug, thiab qhov ntsuas qhov ntsuas tau raug qhib. Nws muab kev lav phib xaub rau kev txhim kho qhov ua tau zoo ntawm kev tshuaj ntsuam tube txhaj tshuaj ntau lawm thiab ua kom nws lub neej ua haujlwm ntev. Qhov drilling thiab ua tiav txoj hauv kev zoo ntawm qhov chaw zoo yog du, cov ntaub ntawv zoo ntawm lub qhov dej tau mus txog qhov ntsuas qhov xav tau, qhov kev txiav qhov dej tau ua tiav ib zaug, qhov zoo ntawm qhov dej tau tsim nyog, thiab cov cementing zoo tau raws li cov qauv tsim.
Nyob rau hauv cov kauj ruam tom ntej, Drilling Company No. 4 yuav txuas ntxiv hloov Jilin Oilfield mus rau ntsuab thiab huv si, txhawb kev txuag hluav taws xob thiab emission txo, laum qhov dej thiab qhov dej nrawm, thiab pab txhawb kev nthuav dav ntawm kev siv cov khoom siv hluav taws xob hauv nruab nrab thiab qis. permeability reservoirs nyob rau hauv lub oilfield.
