Kev tawg tshiab hauv Kev Tshawb Fawb Txog Kev Tshawb Fawb hauv PetroChina's Zhundong New Area
May 18, 2024
Zoo Kangtan 001H yog thawj qhov kev tshawb nrhiav ua ntej zoo xa tawm los ntawm Tuha Oilfield hauv cheeb tsam Fukang. Nws nyob hauv Kangtan 1 qhov ntswg nce cheeb tsam ntawm Fuzhong trough hauv Fukang Kev Nyuaj Siab. Txij li thaum pib ntawm thaj chaw tshiab thiab kev tshawb fawb teb tshiab hauv xyoo 2023, cov kws tshawb fawb tau soj ntsuam kev tshawb fawb ntxov thiab kev nkag siab txog geological. Nyob rau hauv lub ntsej muag ntawm complex geological tej yam kev mob, lawv tau rov nkag siab txog cov qauv qauv, rov nkag siab txog kev faib cov xuab zeb lub cev thiab cov reservoirs zoo los ntawm "peb rov nkag siab" qhov, rov nkag siab txog lub reservoir yam ntxwv, thiab tawm tswv yim tshiab. kev nkag siab ntawm tag nrho cov reservoir tsim, hauv zos enrichment thiab siab ntau lawm ntawm Upper Wuerhe Tsim nyob rau hauv lub Fuzhong trough cheeb tsam. Los ntawm kev nkag siab ntawm reservoir faib cov yam ntxwv thiab cov khoom siv roj, ua ke nrog ntau qhov sib txawv ntawm seismic attribute inversion, nws tau raug lees paub tias cov xuab zeb lub cev reserves nyob rau theem III ntawm Upper Wuerhe Formation nyob rau hauv cheeb tsam no yog loj nyob rau hauv scale thiab muaj feem ntau zoo. lub cev muaj zog, ua rau nws tsim nyog rau kev tshawb fawb ntawm kab rov tav zoo ntau lawm li tshuab. Lub qhov dej Kangtan 001H tau muab tso rau hauv qhov siab ntawm txoj siv lub qhov ntswg.
Thaum lub sijhawm drilling txheej txheem, Lub Chaw Tshawb Fawb tau tsim ib pab pawg tshawb fawb sai ntawm kev sib koom ua ke ntawm kev txhim kho kev nrawm nrawm thiab geological steering. Kev tsom mus rau lub hom phiaj nrawm, peb tau siv qhov zoo ntawm kev sib koom ua ke ntawm geological engineering thiab kev tshawb fawb tsim cov phiaj xwm nrawm. Cov kws tshaj lij ntawm Party A thiab Party B tau mus rau qhov chaw los txhawb kev sib koom ua ke thiab ua raws li kev ntsuas ceev ntawm txhua qib. Nws tau kov yeej cov teeb meem drilling zoo xws li qhov siab tsis zoo hauv lub hom phiaj txheej, qhov faus loj hauv qhov tob, thiab tsis zoo drillability, thiab ua tiav 6, 290-meter drilling hauj lwm nrog lub voj voog drilling ntawm 70.2 hnub thiab lub voj voog ua tiav ntawm 78.5. hnub, ua tiav cov hom phiaj ntawm kev ceev drilling thiab siab cementing zoo 25 hnub ua ntej lub sijhawm.
Tsom ntsoov rau lub hom phiaj geological steering lub hom phiaj ntawm cov kab rov tav, Lub Chaw Tshawb Fawb tau tsim ib pawg neeg ua haujlwm nyob rau ntawm qhov chaw, thiab cov kws tshaj lij ntawm cov roj av thiab cov tuam txhab cov kws tshaj lij ua tib zoo ua raws thiab muab kev taw qhia. Ib hnub thiab hmo ntuj steering lub luag hauj lwm mechanism thiab ib tug saib xyuas lub luag hauj lwm mechanism tau tsim nyob rau ntawm qhov chaw los saib xyuas kev siv lub kauj thiab taw qhia kev ntsuas thoob plaws hauv tus txheej txheem, thiab ntxiv dag zog rau kev txiav txim zoo. "Dual-post" kev txhawb nqa tau ua tiav qhov chaw cia khoom ntawm qhov drilling ntawm 91.0%.
Lub Tuam Txhab Tshawb Fawb tau ua tib zoo teeb tsa kev sib tham txog kev sim thiab ua tiav txoj kev npaj rau Well Kangtan 001H, thiab ua ib qho kev sim 14-theem 43- pawg ntim cov roj fracturing. Tam sim no, lub 4 hli + 4.5 hli ob-theem nozzle yog siv rau lub tshuab nqus tsev, nrog rau cov kua txhua hnub ntawm 202.1 cubic meters, nrog rau 102 cubic meters ntawm cov roj crude. , 7549 cubic meters ntawm natural gas, thiab lub taub hau siab tseem nyob ruaj khov tshaj 40 MPa. Nws muaj cov yam ntxwv ntawm cov roj tawg thaum ntxov thiab nce nrawm ntawm cov roj cov ntsiab lus. Raws li cov roj cov ntsiab lus piv tau nce ntxiv, kev tsim khoom yuav tsum tau nce ntxiv.
Kev tshawb nrhiav kev ua tiav ntawm Well Kangtan 001H tau lees paub tias cov dej xuab zeb sib xyaw ua ke nrog qhov tob ntawm ntau dua 5, 000 meters tuaj yeem siv tau zoo siv cov qhov dej kab rov tav. Nyob rau hauv cov kauj ruam tom ntej no, lub oilfield yuav txuas ntxiv mus ua kom tiav kev tshawb nrhiav thiab kev loj hlob xa mus, ua kom lub expansion ntawm reserve scale thiab tag nrho cov txawj tej yam ntxiv thiab siv, thiab consolidation cov peev txheej ntawm lub oilfield "peb 1 lab tons" lub hom phiaj tswv yim.
