6 017m! Cov ntaub ntawv rau luv tshaj Drilling Cycle Teeb nyob rau hauv North China Oilfield
May 24, 2024
Kev siv lub qhov dej kab rov tav los tsim cov roj thiab cov roj av tuaj yeem ua rau cov roj thiab cov roj ntau lawm, cov nqi rov qab thiab cov roj rov qab nrawm dua, thiab siv cov peev txheej uas tsis tuaj yeem siv tau raws li qhov kev xav tau, uas muaj txiaj ntsig zoo rau kev lag luam. Raws li kev txheeb cais, qhov tso zis ntawm ib lub qhov dej kab rov tav yog ntau tshaj peb zaug ntawm lub qhov dej ncaj, thiab nws muaj peev xwm ua kom ruaj khov ntau lawm rau lub sijhawm ntev. Xinghua block ntawm Bayan Oilfield muaj kev sib kis loj ntawm cov roj xuab zeb thiab ruaj khov stratigraphy, uas ua tau raws li cov xwm txheej ntawm kev tsim kho kab rov tav, tab sis qhov tob ntawm cov roj txheej faus rau hauv lub stratum yog ntau tshaj 4,500 meters, thiab qhov kub ntawm stratum ncav cuag 142.7 degrees Celsius, uas tsim cov yam tsis zoo rau kev ua haujlwm ntawm qhov tob tob thiab ultra-siab kub.
The Geological Engineering Research Center of North China Oilfield Branch prepares the program in accordance with the principle of "one well, one policy", and strictly controls the whole process from design, construction, safety and quality, meanwhile, it actively maintains technical exchanges and communication with the construction side, and supervises the wells 24 hours a day, giving full play to the synergistic effect of "1 +1 > 2", avoiding waiting and stopping, and greatly shortening the construction period. The synergistic effect of "1+1>2 "yog muab kev ua si tag nrho rau, zam kev tos thiab nres, ua kom luv luv ntawm kev tsim kho lub voj voog, thiab ua tib zoo npaj thiab ua tiav cov kev tshawb fawb nrawm rau ntau tshaj 10 zaug rau cov teeb meem ntawm kev ruaj ntseg tsis zoo ntawm cov av nkos ntawm Linhe pab pawg, kev co siab ntawm cov twj paj nruag. , thiab kev sib tsoo loj ntawm cov khoom siv hauv qhov thaiv no, thiab daws cov teeb meem nyuaj thaum hmo ntuj rau 3 zaug Nws yuav siv sij hawm ntau lub siab tawv thiab kev txawj ntse los laum kab rov tav dua li ntsug, thiab txhua lub meter ntawm qhov drilling zoo sib sau ua ke ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim kho tshiab.
Kab rov tav qhov dej yuav tsum tau txuas mus rau kab rov tav, qhov kev sib txhuam tsis sib haum yog ntau dua li cov qhov dej ncaj, thiab yuav tsum tau siv cov cuab yeej qhia kev ua haujlwm siab, lub laum me ntsis "tsau rau lub hom phiaj" yog qhov nyuaj dua, pab pawg ua haujlwm koom ua ke ntawm cov thev naus laus zis tshiab thiab tshiab. khoom siv, thiab kov yeej kev sib tw technical.
Nyiam txoj kev nqes hav-tsim tus nqi teb cov lus qhia cov cuab yeej, daim ntawv thov ntawm ob-kab cov hniav hnav-tiv taus laum khoom, cementing accessories "kaw-hauv valve", kev siv "kev txhawb nqa lub cev + tshuaj plugging" dual tiv thaiv kev sib tsoo, kos duab rau cov kev paub ntawm tib hom kab rov tav qhov dej kom optimize qhov tob qauv, thiab thaum kawg, 519, ib tug tag nrho ntev ntawm 6010 meters ntawm lub Casing, tsim ib tug roj rov qab "txoj kev loj", thiaj li hais tias lub qhov dej tsis yog tsuas yog "ntaus mus rau hauv" , tab sis kuj mus cuag lub "ntaus yog" "ntaus zoo!".
Xinghua 1 Ping 5 zoo nyob rau hauv cov ntaub ntawv tshiab nyob rau tib lub sij hawm, tsim ib tug xov tooj ntawm kev ua tau zoo, yuav tsav lub platform tsim nyob ib ncig ntawm lub realization ntawm npaum txoj kev loj hlob thiab kev siv ntawm cov roj thiab roj.
