Thawj Qhov Kev Sib Tw Hauv Ntiaj Teb Sib Nqus Shale Gas Roj-based Drilling Fluid Well Cooling Test tau ua tiav qhov tseem ceeb
Nov 11, 2023
Thaum Lub Kaum Ib Hlis 9, peb tau kawm los ntawm Southwest Oil thiab Gas Field Company tias Well Yang 101H13-4 tau ua tiav drilled mus rau 5920 meters, thiab deflection + kab rov tav seem ntawm 1930 meters tau ua tiav hauv ib qho kev mus ncig. Qhov zoo siv cov txheej txheem tshiab hloov cov khoom cua txias ntawm nws tus kheej tsim los ntawm Southwest Oil thiab Gas Field Company. Cov txiaj ntsig kev ntsuas tau pom tias qhov ntsuas kub hauv qab qhov ntsuas kub muaj qhov qis qis qis thiab cov cuab yeej siv lub tshuab ua haujlwm tau ua haujlwm ruaj khov. Qhov no tau cim qhov kev ua tiav ntawm thawj qhov sib sib zog nqus shale roj roj-raws li drilling kua downhole txias ntsuas. kev vam meej tseem ceeb.
Lub Longmaxi Tsim nyob rau hauv Luzhou thaiv yog faus tob, muaj lub siab coefficient loj, thiab muaj qhov kub thiab txias. Thaum lub sij hawm drilling txheej txheem ntawm kab rov tav qhov dej, nws ntsib kev nyuaj xws li kub kub thiab siab siab. Lub Tuam Txhab Southwest Oil thiab Gas Field Company ib txwm ua raws li kev coj noj coj ua ntawm cov thev naus laus zis tshiab, txuas ntxiv mus ua kev tshawb fawb txog cov txheej txheem tshiab thiab cov thev naus laus zis tshiab, thiab nws tus kheej tsim cov txheej txheem ntawm cov cuab yeej drilling zoo uas txhim kho kev nrawm thiab ua haujlwm tau zoo.
Raws li kev tshawb nrhiav thiab kev loj hlob ntawm cov roj shale sib sib zog nqus txav mus rau "sib sib zog nqus xiav", lub hauv qab qhov kub ntawm qhov kub nce ntxiv. Raws li kev tshawb fawb ywj pheej thiab kev txhim kho ntawm cov roj-raws li drilling kua dej txias tshuab hauv theem pib, lub tuam txhab koom tes nrog Southwest Petroleum University los ua cov kev tshawb fawb txog roj-raws li drilling kua downhole txias tshuab. , nws siv sijhawm ib xyoos los ua tiav cov roj-raws li drilling kua theem hloov cov ntaub ntawv txias thiab daim ntawv txhawb cov txheej txheem thev naus laus zis. Tom qab ntau qhov kev ua yeeb yam ua qauv qhia, ntau pab pawg ntawm kev soj ntsuam sab hauv tsev, ntau qhov kev soj ntsuam ntawm qhov chaw thiab cov lus qhia luv luv, qhov kev sim ntawm qhov chaw tau ua tiav thaum Well Yang 101H13-4 raug drilled mus rau sab kab rov tav ntawm 1,600 meters. Thaum lub sij hawm ntsuas, qhov ntsuas kub nyob rau hauv qab ntawm lub qhov dej txuas ntxiv txo los ntawm 3 degrees Celsius. Qhov kub siab tshaj plaws hauv qab tsuas yog 134 degrees Celsius, uas yog ntau dua 8 degrees Celsius qis dua lwm qhov dej ntawm tib lub platform. Qhov kev ua tau zoo ntawm cov kua dej drilling yog qhov ruaj khov thiab cov kev ntsuas kev ua haujlwm tsis zoo yog qhov ruaj khov, ua tau raws li cov kev xav tau ntawm cov dej sib sib zog nqus shale gas kab rov tav.
Hauv cov kauj ruam tom ntej, Southwest Oil thiab Gas Field Company yuav txuas ntxiv ua qhov kev sim ntawm cov roj-raws li drilling kua dej txias tshuab, raws sij hawm sau thiab txheeb xyuas, ntxiv optimize thiab txhim kho cov drilling txhawb technology, ntxiv cov cuab yeej tshiab rau cov txiaj ntsig thiab Kev loj hlob loj ntawm cov roj shale sib sib zog nqus hauv Luzhou thaiv, thiab txhawb nqa Luzhou District Kev tsim kho kom zoo ntawm kaum tawm billions ntawm shale gas teb.
