PetroChina Ntxiv Cov cuab yeej muaj zog rau Deepwater Perforation Test Tsim

CNPC Well Logging ua tiav peb theem, stratified, thiab lub sij hawm sib koom dual-pressure detonation perforating kev sib koom tes kev sib tw thev naus laus zis, muab cov peev txheej tshiab rau kev tsim kho sab nrauv perforating.

Thaum tsim kho ntawm cov dej hiav txwv loj, qhov nrawm ntawm txhua hom phiaj xwm txhais tau tias yuav txo qis hauv kev txhim kho cov nqi. Hauv kev tsim cov roj av thiab roj av ib txwm muaj, kev ntsuas kev siv tshuab perforation muaj qhov tsis zoo xws li lub voj voog ua haujlwm ntev, kev ua haujlwm siab, thiab kev tiv thaiv tsis zoo. Txog rau qhov kawg no, CNPC Well Logging Offshore Technology Team tau tsim thiab tsim ob txheej txheej txheej sijhawm sib koom ua ke perforation kev sim thev naus laus zis hauv ib qho kev mus ncig ntawm txoj hlua. Yuav kom ua tiav ntau txheej perforation nyob rau hauv ib qho kev mus ncig ntawm txoj hlua, cov kws tshaj lij tau tshawb xyuas qhov tob ntawm cov kev sib txuas tseem ceeb xws li qhov kub thiab txias ntawm lub perforator, kev tiv thaiv kev cuam tshuam ntawm txoj hlua, lub zog compressive, thiab kev tswj. ntawm cov kev xeem channel, innovated txoj hlua qauv, tackled ob-txheej perforator graded detonation tshuab, systematically sim cov txheej txheem xeem channel tswj system, comprehensively configured txoj hlua zog, thiab optimized kev ruaj ntseg system nyob rau hauv txoj hlua. Lub tshuab no siv ib qho kev mus ncig ntawm txoj hlua kom paub txog kev sib xyaw ntawm ob txheej ntawm cov perforators thiab cov cuab yeej ntsuas roj mus rau qhov dej ntawm ib zaug, thiab siv cov packer los teeb cov khoom siv hauv dej rau hauv ob txheej ntawm perforators. Li Bin, tus kws tshaj lij qib thib ob uas yog tus saib xyuas qhov project, tau qhia tias: "Peb thawj zaug detonate thawj txheej ntawm cov phom perforating los ntawm lub siab thiab nkag mus rau hauv cov txheej txheem sim. Tom qab qhov kev sim ua tiav, txheej thib ob ntawm cov phom perforating tau tawg los ntawm kev pov. rods tsis muaj lub zog zoo thiab txav cov yeeb nkab txoj hlua Lub sijhawm no, cov cuab yeej kaw lub qhov hauv qhov chaw tuaj yeem kaw thawj txheej ntawm cov kua dej ntau lawm thiab sim cov txheej thib ob ib leeg. Tus yuam sij rau kev ntsuam xyuas cov txheej txheem thiab cov roj zoo yog ua kom tsis muaj kev cuam tshuam ntawm ob txheej ntawm cov kua dej ntau lawm. Txhawm rau daws qhov teeb meem no, cov kws tshaj lij ua haujlwm tau zoo ua ke cov ntsiab lus ntawm classical engineering mechanics nrog cov hauv paus ntsiab lus ntawm kev sib kis ntawm cov tshuab thiab tsim cov kev ua haujlwm uas muaj kev cuam tshuam thiab kev sib cais ntawm ib leeg. Kev sim perforating kev tsim kho ntawm Zhanghai 401 Zoo hauv Dagang Oilfield siv cov thev naus laus zis no, txo cov txheej txheem los ntawm 20 mus rau 12, txuag 7.6 hnub nyob rau hauv lub voj voog ntsuas roj, thaum txo cov kev khiav hauj lwm ntawm drilling thiab ntxuav zoo, thiab txo cov kev ua haujlwm zoo. tiam ntawm industrial pov tseg roj thiab dej. CNPC Well Logging yuav txuas ntxiv mus tshawb nrhiav thiab tsim kho ultra-siab kub hydraulic qeeb detonation cov cuab yeej nrog qhov kub tsis kam ntawm ntau dua 200 degrees Celsius hauv kev sib xyaw nrog cov kev xav tau ntawm cov tubing nyuaj TCP perforation hauv offshore dej tob ultra-siab kub qhov dej. Nws yuav tshawb nrhiav thiab txheeb xyuas qhov kev siv tau thiab kev ntseeg tau ntawm cov cuab yeej siv nyob rau hauv ib qho chaw simulated ultra-high temperature wellbore ib puag ncig, thiab maj mam tsim cov txheej txheem ntawm ultra-siab kub hydraulic qeeb detonation tshuab.
