Tshiab nano-drilling kua ntse siv nyob rau hauv Zhejiang Oilfield thawj zaug
Lub qhov dej Jiatan 1H ntawm Zhejiang Oilfield tau ua tiav kev xyaum ua tiav thiab tab tom ua tiav cov haujlwm. Qhov no yog thawj zaug uas Zhejiang Oilfield tau ua tiav kev siv bionic nano-polyfilm uas tsis muaj dej-raws li drilling kua system hauv kev txhim kho cov dej sib sib zog nqus coalbed methane kab rov tav.
Lub geological tej yam kev mob ntawm sib sib zog nqus coalbed methane yog complex, thiab muaj cov teeb meem xws li yooj yim zoo phab ntsa instability, tsawg hluav taws xob ntsuas kev ua tau zoo tus nqi, thiab tsawg drilling timeliness. Txhim kho lub sealing ntawm micropores thiab micro-fractures los ntawm drilling kua yog ib qho ntawm cov kev ntsuas tseem ceeb los daws qhov tsis ruaj khov ntawm phab ntsa zoo. Txij li thaum cov dej drilling uas twb muaj lawm tsuas tuaj yeem kaw qhov pores thiab pob txha pob txha nrog qhov loj me ntawm microns thiab saum toj no, nws tsis zoo ntawm kev sib khi nano qhov pores thiab pob txha, thiab nws nyuaj rau kev tiv thaiv kev sib kis, uas feem ntau ua rau cov phab ntsa tsis ruaj khov thiab cuam tshuam. ib txwm ua haujlwm drilling.
Txhawm rau daws cov teeb meem drilling, Zhejiang Oilfield tau ntxiv dag zog rau nws cov kev tshawb fawb ntawm cov dej-raws li drilling kua rau cov qhov dej tob kab rov tav. Cov kws tshawb fawb tshawb fawb tau daws cov teeb meem ntawm cov dej hauv cov dej drilling xws li cov pob zeb uas tsis muaj peev xwm tuav tau, lubricity tsis zoo, thiab tsis zoo kub tsis kam, thiab tsim cov dej-raws li drilling kua dej haum rau cov dej sib sib zog nqus coalbed methane kab rov tav hauv Zhejiang Oilfield. Qhov no bionic nano-polyfilm tsis tshua muaj dej-raws li cov dej drilling tsis tuaj yeem tsuas yog ua tau raws li kev tsim kho cov kev xav tau ntawm cov qhov dej sib sib zog nqus kab rov tav, tab sis kuj muaj cov nyhuv lubrication zoo dua, tus nqi qis dua, thiab muaj txiaj ntsig zoo rau kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Nws kuj tseem tuaj yeem cuam tshuam cov kev tawg ntawm drilling cuttings, stabilize lub phab ntsa zoo, thiab Nws muaj cov txiaj ntsig zoo kawg nkaus hauv kev txiav cov txiav thiab lwm yam, thiab daws tau cov teeb meem zoo xws li qhov tsis zoo ntawm lub qhov dej thaum lub sij hawm drilling.
