Ntev npaum li cas txhawm rau txhawm rau 8,000-meter-qhov tob- Qhov ceev tshaj plaws tsuas yog 118 Hnub
Feb 17, 2024
Kev tshawb nrhiav roj thiab roj thiab kev tsim kho hauv Tarim Basin txuas ntxiv mus tob rau hauv lub ntiaj teb. Ib qhov dej siab tshaj 8, 000 meters tob tau drilled nyob rau hauv lub roob Kuqa frontier nrog complex geological tej yam kev mob thiab nyob rau hauv lub Taklimakan suab puam, hu ua "Hiav txwv tuag."
Tab sis koj puas paub tias nws yuav siv sij hawm ntev npaum li cas txhawm rau txhawm rau qhov tob tshaj 8,000 meters tob? Cov lus teb tau muab los ntawm Tarim Oilfield yog: nws siv sijhawm ntau dua 700 hnub hauv xyoo 2007, ntau dua 400 hnub hauv xyoo 2015, ntau dua 300 hnub hauv 2018, thiab tam sim no lub sijhawm nruab nrab yog 220 hnub. Tam sim no, lub sijhawm drilling ceev tshaj plaws hauv Fuman Oilfield tau 118 hnub.
Cov khoom siv roj thiab roj ntau dua 6, 000 meters hauv Tarim Basin account rau 83.2% thiab 63.9% ntawm tag nrho cov peev txheej roj thiab roj hauv lub tebchaws raws li, thiab kwv yees li 19% ntawm tag nrho cov kev sib sib zog nqus ultra-dav. cov khoom siv roj thiab roj hauv ntiaj teb. Kev tshawb nrhiav thiab kev loj hlob zeem muag yog dav heev. Txawm li cas los xij, kev tshawb nrhiav thiab kev txhim kho ntawm no yog qhov teeb meem hauv ntiaj teb. Ntawm 13 qhov kev lag luam-pom zoo txog kev drilling thiab ua tiav cov teeb meem nyuaj, Tarim Basin yog thawj zaug hauv ntiaj teb hauv tsib.
Los ntawm kev tshawb nrhiav kev tshawb fawb thiab thev naus laus zis tas li, Tarim Oilfield tau ua kom muaj kev cuam tshuam loj hauv cov thev naus laus zis tseem ceeb txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau muaj zog, nyuaj thiab nyuaj-rau-drill formations sawv cev los ntawm siab, ntxhab, thiab tuab gravel txheej, txhawb kev sib sib zog nqus roj thiab roj. drilling yuav tsum tau drilled sai, raug, thiab zoo. , yog li txuas ntxiv accelerating txoj kev loj hlob ntawm ultra-deep enriched roj thiab roj.
Txog tam sim no, 72 qhov dej tob tshaj li 8,000 meters tau raug tho. Ntawm lawv, Well Keshen 1 yog thawj qhov dej siab tshaj 8, 000 meters hauv Kuqa Roob Piedmont. Nws tau drilled nyob rau hauv 266 hnub, teem ib tug tshiab drilling thiab tiav lub voj voog cov ntaub ntawv; Zoo Dabei 13 coj tsuas yog 140 Lub qhov dej tau drilled mus rau qhov tob ntawm 5,330 meters, 53 hnub ua ntej lub sijhawm; Zoo Manshen 71 tau drilled mus rau 8,492 meters thiab ua tiav nyob rau hauv 140.8 hnub; Zoo Fuyuan 3-H3 tau drilled mus rau 8,136 meters hauv 118 hnub, teeb tsa cov ntaub ntawv ceev tshaj plaws hauv qhov thaiv.
"Cov txheej txheem nyuaj thiab nyuaj rau kev xyaum yog ib qho teeb meem loj hauv kev tshawb nrhiav roj thiab roj. Ua ntej kev tshawb fawb thiab thev naus laus zis, cov cuab yeej drilling yog cov cones thiab cov pa PDC (ib hom laum me ntsis) laum cov khoom. Thaum lub sij hawm cov txheej txheem drilling, Cov khoom siv laum siv ntau npaum li cas thiab muaj lub neej luv luv. Qhov nruab nrab laum me ntsis Lub voj voog ntawm lub qhov dej zoo tshaj 500 hnub, uas txwv tsis pub txoj kev tshawb nrhiav thiab kev loj hlob. " Li Ning, tus kws tshaj lij kev lag luam ntawm Tarim Oilfield Oil thiab Gas Engineering Research Institute.
Laum me ntsis kev ua tau zoo cuam tshuam ncaj qha rau drilling ceev thiab efficiency. Tarim Oilfield txuas ntxiv tshawb fawb thiab sim tshiab cov cuab yeej ua tau zoo tshaj plaws thiab cov cuab yeej txhawb nqa, tsim tawm lub tswv yim tshiab ntawm "lub zos siab compression-tension-shear" cov pob zeb sib xyaw ua ke, tawg los ntawm "tsis tuaj yeem xyaum" qhov teeb meem tshawb nrhiav, tsim thiab kev sim. tshiab "polygonal hniav" + Tapered hniav + Arrow polygonal hniav" muaj kev cuam tshuam loj sib xyaw cov hniav tho me ntsis, muab kev ua si tag nrho rau qhov zoo ntawm ntau cov hniav txiav, hloov qhov xwm txheej qhov nruab nrab thiab sab sauv gravel txheej yog dominated los ntawm cone khoom, thiab tiag tiag realizing "zoo li cas ntawm ko taw hnav dab tsi" "Cov khau zoo li no" muab cov cuab yeej tseem ceeb rau kev nyab xeeb thiab ua haujlwm tob tob hauv kuv lub teb chaws.
Nyob rau hauv complex thiab nyuaj-rau-drill formations, Tarim Oilfield tau tsim ib tug ua ke ntawm "vibration absorber / ntsia hlau + ntsug drilling + high-efficiency PDC me ntsis" raws li lub hauv paus, thiab tus naj npawb ntawm daim ntawv thov qhov dej account rau ntau tshaj 90%. Piv nrog rau cov qhov dej uas nyob ib sab uas tsis siv cov cuab yeej no, cov duab thiab ROP ntawm ib qho kev xyaum me ntsis tau nce ntau dua 50%.
Ua siab tawv nce toj "Mount Everest" ntawm kev tshawb nrhiav roj thiab roj thiab kev tsim kho thev naus laus zis, Tarim Oilfield tau tsim cov cuab yeej siv nrawm nrawm thiab cov cuab yeej siv tshuab nrog cov cuab yeej ywj pheej ywj pheej, thiab tau yeej thawj qhov khoom plig ntawm thaj tsam Autonomous Science thiab Technology Progress Award thiab thawj qhov khoom plig ntawm Tuam Tshoj Petroleum thiab Chemical Industry Federation's Technology Invention Award. . Tam sim no, Tarim Oilfield tau nthuav dav kev siv cov thev naus laus zis tseem ceeb rau kev nrawm hauv cov txheej txheem nyuaj thiab nyuaj rau kev xyaum, thiab tau koom ua ke 100% ntawm lawv rau hauv kev npaj geological engineering.
Raws li kev txheeb cais, qhov nruab nrab txhua xyoo drilling qhov tob ntawm Tarim Oilfield hauv 2022 yuav ncav cuag 7,098 meters, tawg 7,000-meter cim thawj zaug. Lub voj voog drilling thiab ua tiav yuav luv luv los ntawm 12.2 hnub rau ib xyoos, thiab qhov drilling ceev yuav nce 5.57%.
