Yog tias koj xav sib tw qhov tob ntawm 10, 000 Meters, Koj Yuav Ua Li Cas Tsis Tau Txais Cov Cuab Yeej Drilling Hauv Tsev

Drilling ntawm kuv lub teb chaws thawj Wanmike kev tshawb nrhiav qhov dej, Shenzhen Tako 1 Zoo, tab tom ua tiav. Qhov chaw drilling yog nyob rau hauv hinterland ntawm Taklimakan suab puam hauv Xinjiang. Txij li thaum drilling tau pib thaum lub Tsib Hlis 30 xyoo tas los, tom qab ntau tshaj 200 hnub ntawm kev drilling, peb tau ua haujlwm hnyav kom nce mus txog 10,000 meters.
Raws li ntawm 9 teev sawv ntxov hnub no, Shenzhen Taco 1 Qhov Zoo tau raug drilled mus rau 9,969 meters hauv av. Raws li qhov kev nce qib tshiab tshaj plaws tau kawm los ntawm tus neeg sau xov xwm, qhov nrawm nrawm tam sim no yog kwv yees li 0.5 meters ib teev. Lub laum me ntsis yog tsoo los ntawm kev thaiv ntawm cov pob zeb hauv av nyuaj thiab mus rau qhov kawg ntawm 30 meters ntawm 10,000-meter stratum.

Hauv tsev drilling "ntshav" nyuaj rau qhov tob ntawm 10, 000 meters thawj zaug

Drilling kua yog hu ua "ntshav" ntawm drilling. Thaum lub sij hawm drilling txheej txheem ntawm thawj Wanmike kev tshawb fawb zoo, kuv lub teb chaws ntawm nws tus kheej tsim ib tug drilling kua system haum rau ultra-siab kub thiab ultra-siab siab formations, uas tau los ua ib tug haib cuab tam los mus kov yeej cov teeb meem drilling ntawm ultra-dav formations.

Drilling kua muaj ntau yam haujlwm xws li nqa cov txiav, ntsuas qhov tsim kom muaj zog, thiab ua kom txias lub laum me ntsis. Ob peb hnub dhau los, qhov no 10,000-meter-qhov tob zoo siv cov dej hauv tsev drilling kom ua tiav nrog cov dej ntws tawm hauv av, tsim cov xwm txheej zoo rau kev khawb ntxiv.

Yin Da, tus kws tshaj lij ntawm PetroChina Tarim Oilfield Drilling Fluid Company: Tam sim no, qhov tshiab-kub kub resistant dej-raws li drilling kua tshuab hauv Deep Tako 1 Zoo, uas yog tsim los ntawm tag nrho cov khoom siv hauv tsev, tau dhau qhov kev coj ua hnyav. kev ua haujlwm ntawm qhov tob tob ntawm 10, 000 meters. Tom qab kev tshuaj xyuas, nws ua tau raws li qhov tsim nyog rau ultra-siab kub tsis kam ntawm 220 degree. Nyob rau hauv cov kauj ruam tom ntej, peb yuav txuas ntxiv mus daws cov teeb meem tseem ceeb thiab txhim kho mus rau ultra-siab kub siab tshaj 240 degree kom tau raws li qhov xav tau ntawm kev ua haujlwm drilling hauv qhov tob hauv lub ntiaj teb.

Hauv qab ntawm lub qhov dej nrog qhov tob ntawm 10, 000 meters nce mus txog qhov kub siab tshaj ntawm 220 degree thiab lub siab siab ntawm 150 MPa. Ib yam li lub cooker siab, tag nrho cov zaub mov yuav raug siav kom tuag nyob rau hauv qhov kub thiab txias ib puag ncig. Yog tias cov kua dej drilling tsis txaus rau qhov kub thiab txias, nws yuav lwj thiab deteriorate. Thaum nws qhov kev ua tau zoo tsis zoo, kev sib tsoo hauv av yuav tshwm sim.

Yin Da, tus kws tshaj lij ntawm PetroChina Tarim Oilfield Drilling Fluid Enterprise: tau ua ntau txhiab qhov kev sim, xaiv thiab tsim ntau pua cov ntaub ntawv, ua kom zoo dua ntau tus qauv, tsim xya lossis yim txheej ntawm cov phiaj xwm, thiab thaum kawg tau ua qauv qhia thiab txiav txim siab ob pawg ntawm cov dej drilling. Ntawm cov kev daws teeb meem, ib qho yog siv rau ntawm qhov chaw thiab lwm qhov yog nyob rau hauv standby. Txog tam sim no, peb tau tawm tsam kom kov yeej qhov kev nyuaj ntawm geological ntawm kaum ob qhov sib txawv, thiab tau kov yeej cov teeb meem kev ua haujlwm xws li kev ua dej tsis zoo, kev tawg loj heev, kub kub corrosion, kub kub blistering, thiab high-temperature thickening. Peb tab tom ua haujlwm ib kauj ruam kom ua tiav "zero complexity", xoom kev sib tsoo" ua tiav, nce mus txog 10,000-meter mark.

Yav dhau los, Tarim Oilfield tau tso siab rau nws tus kheej tsim qhov tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob tob qhov tob tob tob tob tob tob qhov tob tob 139 qhov dej tob tob tshaj 8,{4}} meters, muab kev txhawb zog drilling dej rau qhov tob ntawm 10. , 000 meters.

Ntau txhiab-meter sib sib zog nqus drilling cov cuab yeej tiv taus qhov kev sim siab

Qhov ze ntawm qhov drilling qhov tob yog mus rau qhov tob ntawm 10, 000 meters, qhov hnyav dua qhov kev ua haujlwm hauv av tau dhau los. Drilling cov cuab yeej yeej ib txwm raug kev nyuaj siab heev. Engineering thiab technical cov neeg ua haujlwm ib txwm saib xyuas cov xwm txheej ua haujlwm ntawm downhole drilling cuab yeej kom ntseeg tau tias kev nyab xeeb drilling.

Tam sim no muaj 1,026 cov cuab yeej drilling siv hauv av. Cov cuab yeej drilling lawv tus kheej hnyav dua 350 tons. Cov cuab yeej drilling tig thiab tsav cov laum khoom kom tawg lub pob zeb. Tag nrho cov txheej txheem yog zoo li twisting twist ntawm ib tug ntev ntawm 10 kilometers. Ultra-siab loads, ultra-ntev deb thiab muaj zog underground vibrations raug cov cuab yeej drilling rau kev sim hnyav.

Lu Qiang, Senior Technical Expert ntawm Drilling Tools ntawm PetroChina Tarim Oilfield: Tom qab lub hiav txwv tob Taco 1 Zoo drilled mus rau 9, 000 meters, peb yuav pom txawv tus naj npawb ntawm qaug zog tawg nyob rau hauv threads ntawm lub drilling cuab tam txhua zaus. peb laum. Qee zaum ib lossis ob, qee qhov Yog tias qhov tawg tsis pom nyob rau lub sijhawm, lawv tuaj yeem tawg thiab ua rau muaj xwm txheej loj.

Lu Qiang hais rau cov neeg sau xov xwm tias cov txheej txheem drilling yog ze li ntawm 10, 000 meters, lub xeev ntawm kev txav thiab kev ntxhov siab yog qhov nyuaj heev, thiab kev hloov hluav taws xob nyuaj heev. Kev qaug zog tawg tau pom nyob rau hauv 43 cov cuab yeej drilling ntawm lub qhov dej.

Lu Qiang, tus kws tshaj lij ntawm cov cuab yeej drilling hauv PetroChina Tarim Oilfield: Muaj ntau dua 1,000 xyaum xyaum nrog ntau dua 2,000 pob qij txha, thiab yuav tsum tsis muaj teeb meem nrog ib qho ntawm lawv. Threaded pob qij txha ntawm cov cuab yeej drilling yog qhov ua tsis tiav. Peb nruj me ntsis tswj lub sij hawm siv cumulative thiab ntxiv dag zog saib xyuas. Xyuas kom tseeb tias cov cuab yeej drilling muaj kev nyab xeeb.
