Oct 23, 2023
Thaum Lub Kaum Hli 18, cov xov xwm zoo siab tuaj ntawm Daqing Drilling. LGPC4-6-7H zoo drilled los ntawm 50018 drilling pab neeg ntawm lub tuam txhab Shaanxi-Jinxi Drilling Project Management Department tau ua tiav drilled mus rau qhov tob ntawm 3,192 meters. Lub qhov dej yog cov ntaub ntawv tsis tau muaj nyob rau ntawm ntug dej rau CNOOC. Lub voj voog drilling thiab ua tiav ntawm qhov sib sib zog nqus coal-bed methane kab rov tav qhov dej yog 13.66 hnub, thiab cov duab txhua hnub ntawm cov kab rov tav yog 460 meters, cim qhov kev ua tiav tshiab hauv kev drilling ceev.
Txij li thaum pib ntawm lub xyoo, lub tswv yim kev koom tes ntawm Daqing Drilling thiab Tuam Tshoj National Offshore Roj Corporation tau txuas ntxiv mus tob. 31 drilling rigs thiab ntau pab pawg kev pabcuam hauv ntau qhov chaw tau nkag mus rau hauv kev ua lag luam, tsim lub sijhawm zoo rau kev pabcuam geological engineering. Nyob rau tib lub sijhawm, Shaanxi-Jinxi Drilling Project Management Department nquag txhim kho nws cov peev txheej ntawm qhov chaw pabcuam thiab ntxiv dag zog rau kev tshawb fawb. Nws tsoo cov ntaub ntawv ntau lawm 14 zaug, tau txais 12 tsab ntawv qhuas los ntawm Party A, thiab tswj xyuas qhov drilling thiab ua tiav lub voj voog ntawm kab rov tav ntawm coalbed methane thiab qhov siab tshaj plaws drilling footage nyob rau hauv ib qho chaw twg. , qhov nruab nrab txhua hnub footage ntawm ib lub qhov dej, cov duab txhua hnub ntawm ib hnub thiab ntau lwm cov ntaub ntawv. Nrog rau kev siv thev naus laus zis zoo tshaj plaws, kev nyab xeeb thiab kev ua haujlwm tau zoo, nws tau txais kev lees paub los ntawm txhua tog neeg, tso cai rau pab pawg Ironman tsa tus chij thiab teeb tsa cov qauv hauv thaj av Shaanxi thiab Shanxi.
Zoo LGPC4-6-7H nyob hauv Shenmu City, Shaanxi Province. Nws yog qhov thib ob sib sib zog nqus coalbed methane kab rov tav zoo qhib nyob rau hauv Shenfu Ua Haujlwm Cheeb Tsam ntawm CNOOC Tuam Tshoj United Tuam Txhab. Kev tsim kho ntawm ob lub qhov dej nyob rau hauv pem hauv ntej ntawm lub platform pom tias Liujiagou Formation yog ib qho nyuaj thiab lub sijhawm drilling qeeb. Txhawm rau daws cov teeb meem xws li kev taw qhia teeb meem, Daqing Drilling xaiv cov cuab yeej drilling ceev-ntau ntxiv los txhim kho qhov hnav tsis kam ntawm cov cuab yeej drilling rau cov txheej txheem nyuaj, txhim kho kev ua haujlwm ntawm ib qho kev ua haujlwm drilling, ua kom raws sijhawm rau cov dej drilling, thiab kho qhov dej ua ntej. hloov mus rau kev tsim cov khoom ua ntej drilling mus rau hauv complex formations. kua dej los xyuas kom meej qhov txuas ntxiv ntawm kev ua haujlwm drilling thiab kev nyab xeeb hauv av. Ib qho kev xyaum me ntsis ua tiav 1,139 meters ntawm footage nyob rau hauv txoj kab ntsug ntsug, nrog qhov nruab nrab ROP ntawm 28.83m / h.
Zhang Qingxiu, tus thawj coj ntawm Shaanxi-Jinxi Drilling Project, tau hais tias, "Raws li kev tsim kho ntawm thawj ob lub qhov dej, lub qhov dej no tau npaj ua ntej, thiab kev txhim kho tag nrho ntawm cov cuab yeej drilling thiab cov dej drilling tau dhau los ua qhov kev ua tiav. taw tes rau lub qhov dej no los tsim cov ntsuas ntsuas tau zoo daws cov teeb meem ntawm qhov sib txawv ntawm qhov dej loj, kev txhawb nqa siab, thiab cov dej drilling, cov teeb meem xws li kev ua haujlwm qeeb thiab sijhawm sijhawm. ua hauj lwm zoo ua ke los tsim cov ncauj lus kom ntxaws ntau lawm kom paub meej tias txhua txoj kev sib raug zoo, muab kev txhawb zog rau kev txhim kho kev ceev thiab kev ua haujlwm ntawm qhov dej thiab tsim cov ntsuas siab hauv kev txhawb nqa hauv cheeb tsam. "
Nws tau nkag siab tias Daqing Drilling Shaanxi-Shanxi Project Department tau teeb tsa lub sijhawm drilling thiab ua tiav cov ntaub ntawv ntawm 16.88 hnub rau tib hom qhov dej hauv Well LGPC4-6-6H thaum Lub Kaum Hli 1. Lub qhov dej tau teeb tsa cov ntaub ntawv no dua tsuas yog 17 hnub. tom qab ntawd. Kev kho dua tshiab thiab ua tiav kev ua haujlwm zoo ntawm kev ua tiav 18.34 hnub ua ntej lub sijhawm, thiab muaj peev xwm ua kom qhov drilling ceev txuas ntxiv mus ntxiv.
Txog tam sim no, Daqing Drilling Shaanxi-Jinxi Drilling Project Management Department tau pib 249 qhov drilling thiab ua tiav 248 qhov drilling, nrog rau tag nrho cov duab ntawm 678,500 meters. Nws niaj hnub txhawb kev tsim kho thev naus laus zis thiab tsim lub hauv paus ruaj khov rau kev nthuav dav ntxiv ntawm PetroChina, Sinopec, thiab CNOOC kev lag luam.
