Qhov zoo thiab nta
- Drilling, qhib qhov rais thiab kho qhov rais yog ua tiav hauv ib qho kev mus ncig
- Tshwj xeeb tsim qhov rais qhib milling nkawm khau ua ke nrog cov carbide tuaj yeem
- qhib qhov rais sai sai (2 ~ 4 teev)
- Anchored anti- cov ntawv sib hloov ua kom zoo milling thiab drilling
- Thauj tog rau nkoj thiab whipstock yog retrievable
- Nws tuaj yeem ua tau raws li qhov yuav tsum tau qhib qhov rais ntawm ultra- luv luv radius drilling
Thaum txoj hlua whipstock qis qis rau qhov preset qhov tob thiab kev taw qhia, cov av nkos tau qhib. Tsav los ntawm lub twj tso kua mis siab, lub piston raug thawb kom shear lub anchoring shear pins, yog li ejecting cov ntawv. Tom qab ntawd, txoj hlua yog nias rau hauv qab kom txiav cov bolts txuas ntawm cov khau zeb thiab cov nplawm. Tom qab ntawd, qee qhov kev poob qis yog txuas mus ntxiv kom ntseeg tau tias cov qauv kev thauj mus los tau teeb tsa tag nrho, thiab tom qab ntawd lub qhov rais qhov rais milling tuaj yeem ua tiav. Yog tias nws yog qhov tsim nyog los khaws cov nplawm tom qab, ib qho kev sib txuam taper kais tuaj yeem khiav mus rau hauv qhov dej rau nuv ntses. Tom qab lub taper taper ntse catches lub nplawm, cov hlua yog nqa mus rau ib qho tonnage uas tau teev tseg kom tso cov kev ncua kev ncua thiab khaws cov nplawm.
Txij li thaum nws pib, peb pab neeg R & D tau cog lus rau kev tsim kho tshiab tas mus li, kov yeej ntau yam kev nyuaj siab thiab txhim kho cov cuab yeej ua haujlwm tau zoo thiab txhim khu kev qha downhole drilling cuab yeej, uas tau txhim kho kev ua haujlwm zoo ntawm cov phiaj xwm roj av.
Los ntawm optimizing cov txheej txheem ntau lawm thiab qhia cov khoom siv ntse, peb tsis tsuas yog lav qhov zoo thiab ruaj khov ntawm peb cov khoom, tab sis kuj pab cov neeg siv khoom txo lawv cov nqi khiav lag luam zoo kawg. Coj peb ib qho - mus txawv tebchaws qhov kev tawm qhov system siv hauv CNPC cov haujlwm ua piv txwv. Nws tshem tawm qhov xav tau rau kev ua haujlwm rov ua dua, ua kom txoj haujlwm ua tiav hauv ib qho kev khiav haujlwm. Qhov no tsis tsuas yog txuag lub sijhawm tsim kho tab sis kuj txhawb cov neeg siv khoom ua haujlwm ua haujlwm tsawg kawg 30%Nyeem ntxiv
FAQ
Q: Cov xwm txheej ua haujlwm roj av dab tsi yog qhov no Ib qho - mus ncig Casing Exit System feem ntau haum rau?
A: Nws yog feem ntau siv tau rau cov xwm txheej xws li kev kho lub qhov dej qub qub, cov roj tapping, thiab cov kev taw qhia sab nraud, tshwj xeeb tshaj yog rau cov haujlwm oilfield xws li cov CNPC uas muaj cov kev xav tau siab rau kev ua haujlwm cycles thiab complex wellbore trajectories.
Q: Nws cov txheej txheem tseem ceeb ntawm kev ua haujlwm txawv li cas ntawm cov cuab yeej windowing ib txwm?
A: Tsis tas yuav muaj ntau qhov kev mus ncig ntawm kev khiav thiab rub txoj hlua tho. Tom qab txoj hlua raug txo qis mus rau qhov chaw ua ntej, kev thauj mus los, qhov rai, thiab kev ua haujlwm sab nrauv tuaj yeem ua tiav hauv ib qho mus, tshem tawm cov kauj ruam nyuaj ntawm kev rov ua dua docking thiab commissioning uas yuav tsum tau ua los ntawm cov cuab yeej ib txwm muaj.
Q: Dab tsi yog qhov tshwj xeeb kev ua tau zoo ntawm qhov system no piv nrog cov khoom siv tsoos?
A: Nws tuaj yeem txo lub sijhawm ua haujlwm tsawg kawg 30%, zam qhov kev pheej hmoo ntawm kev rov ua haujlwm dua, thiab txo qhov hnav thiab tsim kua muag ntawm cov khoom siv thaum khiav thiab rub. Nws pab oilfield tej yaam num los txhim kho tag nrho kev tsim kho efficiency.
Q: Yam khoom twg thiab cov kev sib txuas yuav tsum tau tsom mus rau thaum lub sij hawm tu txhua hnub?
A: Nws yog ib qho tsim nyog yuav tsum tsis tu ncua tshuaj xyuas cov hlua khi hlua khi, kev sib khi ua haujlwm ntawm hydraulic pistons, thiab hnav qib ntawm cov cuab yeej txiav. Thaum lub sijhawm khaws cia, tiv thaiv- kev kho xeb yuav tsum ua kom zoo thiab kev ua haujlwm yuav tsum tau ua raws sijhawm.
