1 7545m! Bohai Drilling tsoo cov ntaub ntawv rau lub voj voog luv tshaj plaws!

Pab neeg no ib txwm ua raws li lub koom haum tsim tawm lub tswv yim ntawm "txhua yam hloov pauv nyob ib puag ncig lub qhov dej", hais kom ua tib zoo saib xyuas txhua qhov kev sib txuas, thiab sib zog los txhawb kev sib txuas ntawm kev txiav txim siab ntau lawm, seamless txuas ntawm cov txheej txheem ntau lawm, thiab seamless kev koom tes ntawm cov tog neeg. los xyuas kom meej tias tag nrho lub koom haum ceev tau tiav. . Nyob rau hauv qhov kev pom ntawm qhov teeb meem ntawm qhov thib peb qhib seem ntawm Well Manshen 801, xws li qhov qhib qhov ntev, ntau qhov kev sib tw stratigraphic, yooj yim kom tau daig, yooj yim rau xau, thiab yooj yim rau deflect, ua ntej kev tsim kho, cov kws tshaj lij thiab cov kws tshaj lij pab pawg zoo. npaj kom ua tib zoo txheeb xyuas cov ntaub ntawv ntawm cov qhov dej uas nyob ib sab thiab tsim cov kev zam ua ntej. , nyob rau hauv qhov tseeb drilling, qhov drilling tsis thiab xyaum me ntsis xaiv tau optimized, thiab "peb loj thiab ob siab" drilling tsis ntawm "loj drilling siab, loj torque, loj txav, siab twj tso kua mis siab, thiab kev kub ceev" tau siv, thiab 1.25 degree ntsia hlau + PDC xaiv tshwj xeeb-zoo li tus hniav thiab cov hniav tiaj tus laum khoom raws li cov yam ntxwv sib txawv, thiab ua tiav cov ntaub ntawv ib-hnub footage thiab ob-ko taw footage voj voog cov ntaub ntawv hauv lub block.

Cov pab pawg no tau pib hauv kev tsim kho suab puam txhua xyoo puag ncig. Nyob rau hauv teb rau cov teeb meem ntawm high gas-roj piv thiab kwv yees hydrogen sulfide cov ntsiab lus nyob rau hauv Manshen 72-H1 zoo, raws li zoo raws li muaj kev pheej hmoo ntawm kev tswj kom zoo nyob rau hauv lub hom phiaj txheej, nws ntxiv dag zog rau kev tswj xyuas thiab npaj ua ntej rau zoo to, venting, thiab tag nrho cov hydrocarbons tshaj 30%. Kev tiv thaiv kev pheej hmoo thiab kev tswj xyuas cov dej ntws tawm thiab lwm yam kev ua haujlwm tsis zoo yuav raug siv los tiv thaiv kev ua haujlwm tsis raug cai ntawm cov haujlwm tseem ceeb xws li nres thiab tswj kom zoo. Thaum lub sij hawm tsim kho, ib tug 1.5 degree nkhaus ntsia hlau tau siv nrog ib tug heev txhoj puab heev 5- hniav PDC laum ntsis, thiab cov hydraulic tsis tu ncua ntxiv dag zog raws li cov ntaub ntawv nyob ib sab. Nyob rau hauv lub hauv paus ntawm kev ua kom lub laum me ntsis siab poob thiab ua rau lub drilling hloov chaw, cov txheej txheem kev lag luam drilling tau txuas ntxiv tus qauv thiab txhim kho kom ua tiav Qhov no ua kom muaj kev nyab xeeb drilling thiab ua kom nrawm nrawm.

Pab neeg no yeej ib txwm ua raws li lub tswv yim ntawm "tsis drilling txawm tias ib meter ntawm cov duab tsis zoo". Txo qhov nyuaj ntawm kev nyab xeeb thiab kev tswj kom zoo yog ib txoj hauv kev tseem ceeb los txhim kho kev ceev. Ua tib zoo saib xyuas qhov kev siv ntawm kev ntsuas kev nyab xeeb thiab ntxiv dag zog rau cov txheej txheem kev soj ntsuam ntawm cov kev sib txuas tseem ceeb los muab kev ruaj ntseg ruaj khov rau kev ua kom nrawm nrawm. Thaum lub sij hawm tsim kho ntawm Well Manshen 809, peb tau muab tag nrho cov kev ua si rau qhov zoo ntawm kev sib koom ua ke engineering geology, ua zoo geological kwv yees, standardized ib leeg-thooj thiab nti-los ntawm-inch drilling ua hauj lwm, ntxiv dag zog rau kev saib xyuas ntawm cadres ntawm sab chaw nres tsheb, thiab ua tib zoo saib xyuas cov kev hloov pauv txawv txav hauv qhov ntsuas qhov drilling thiab kev saib xyuas zoo inclination. , kom ntseeg tau tias muaj kev nyab xeeb thiab du ntawm kev tsim kho.
