Ultra-HTHP Production Logging for Extreme Downhole Well Conditions Production loggging in ultra-high temperature and high pressure wells - the over 175 degrees Celsius and 100 MPa - imposes extreme demands on downhole electronics, sealing systems, and mechanical structures. Cov cuab yeej txiav ntoo ib txwm cia siab rau Dewar flask thermal tiv thaiv los tiv thaiv hluav taws xob los ntawm qhov kub thiab txias, tab sis lub raj mis-raws li cov qauv tsim los txwv lub sij hawm nkag mus rau lub thermal so lub sij hawm ntawm lub rwb thaiv tsev, feem ntau yog ob mus rau plaub teev ua ntej qhov kub thiab txias nyob rau hauv ntau tshaj qhov kev ntsuam xyuas. Lub Ultra-HTHP cov cuab yeej txiav cav ntau lawm (VUPT) los ntawm Tuam Tshoj Vigor hais txog qhov kev txwv no los ntawm lub raj mis -dawb architecture uas txuas ntxiv muaj peev xwm nkag mus rau kaum plaub teev lossis ntau dua hauv ib puag ncig txog 200 degrees Celsius thiab 140 MPa.
Flask-Dawb Architecture thiab Materials Engineering
VUPT ua tiav nws qhov kev ntsuas kub siab los ntawm kev xaiv cov txheej txheem ntawm 200 degrees Celsius- ntsuas cov khoom siv hluav taws xob, siab - ntsuas kub, thiab cov ntaub ntawv tshwj xeeb sealing thoob plaws hauv cov cuab yeej. Tag nrho cov khoom siv hluav taws xob raug hlawv- hauv kev tshuaj ntsuam thiab siab - qhov ntsuas kub ntawm 210 degrees Celsius rau 72 teev ua ntej sib dhos, xyuas kom meej tias tsuas yog cov khoom sib ntsib tag nrho cov ntsiab lus raug xa mus rau qhov chaw. Cov cuab yeej vaj tsev yog tsim los ntawm titanium alloy, xaiv rau nws lub zog siab - mus rau - hnyav piv, corrosion kuj, thiab thermal stability. Titanium tus coefficient ntawm thermal expansion zoo sib xws ntawm cov khoom siv hluav taws xob sab hauv, txo qis thermally induced kev ntxhov siab ntawm cov khoom sib cuam tshuam thaum lub sij hawm hloov kub ceev thaum khiav mus rau hauv qhov dej kub.
Sensor Suite thiab ntsuas peev xwm
Lub VUPT muaj nyob rau hauv ob qho tib si 35 hli thiab 43 hli txheej txoj kab uas hla configurations, nrog tag nrho compatibility nrog tus qauv slickline, wireline, thiab coiled tubing conveyance txoj kev. Cov cuab yeej hlua integrates ib tug dav sensor suite:
Quartz siab ntsuas nrog kev daws teeb meem hauv qab 0.008 psi thiab linearity yuam kev tsawg dua 0.01 feem pua ntawm tag nrho cov nplai, muab cov ntaub ntawv tseeb hauv qab qhov siab rau cov dej ntws.
Siab - qhov tseeb qhov kub thiab txias sensor ntsuas rau 175 degrees Celsius nrog ± 1℃Celsius kam rau ua, txuas mus rau 200 degrees Celsius nrog cov khoom tshwj xeeb
Dej tuav sensor nrog ± 5 feem pua qhov tseeb, qhov ntsuas qhov ntsuas qhov ceev nrog 0.01 g / cc daws teeb meem, thiab ntau qhov kev xaiv flowmeter npog 1.2 txog 2.5 meters ib feeb pib tshaj tawm
Manchester-code telemetry txhawb nqa qhov chaw nyeem ntawm 5.7 kbps uplink tus nqi, thaum lub cim xeeb sub muab 512 MB cia muaj peev xwm rau ncua kev nco- hom kev kaw haujlwm.
H2S thiab CO2 Sour Service Compatibility
Rau cov qhov dej uas muaj cov roj corrosive, cov cuab yeej tuaj yeem teeb tsa nrog cov qaub - kev xaiv kev pabcuam rau ib puag ncig uas muaj txog li 20 feem pua hydrogen sulfide thiab 10 feem pua carbon dioxide. Tag nrho cov khoom siv hlau, tsis yog-cov ntaub ntawv hlau, thiab O- nplhaib ntsaws ruaj ruaj yog raug rau H2S thiab CO2 corrosion testing raws NACE TM0177 thiab TM0284 cov qauv kom ntseeg tau tias kev sib raug zoo. Rau cov ntawv thov hauv av uas qhov kub tuaj yeem ncav cuag 260 txog 315 degrees Celsius, VUPT modular tsim tso cai rau Parfluor ultra{13}}cov ntaub ntawv ntim tau hloov pauv rau cov qauv elastomers, txuas ntxiv kev txwv tsis pub dhau qhov kev ntsuas HP / HT. Lub titanium alloy vaj tse muab cov kev tiv thaiv zoo rau sulfide kev ntxhov siab tawg, tshem tawm qhov xav tau ntawm cov coatings lossis cladding hauv kev pabcuam qaub.
Deepwater thiab Geothermal Field Applications
Thaum lub sijhawm kev txhim kho roj av tob hauv thaj av sab hnub tuaj Asia, VUPT ua tiav kev txiav ntoo hauv peb lub qhov dej uas lub qhov dej tau nce siab ntawm 192 degrees Celsius thiab 18,500 psi. Cov cuab yeej nkag mus tsis tu ncua rau kaum plaub teev nyob rau hauv lub cim xeeb hom, tau txais ua tiav cov ntaub ntawv ntau lawm suav nrog kev txhawb nqa zonal, dej tuav, thiab cov ntaub ntawv hauv qab qhov siab. Muab piv nrog cov pa roj carbon monoxide-raws li kev khiav haujlwm uas feem ntau xav tau ntau qhov kev mus ncig thaum muaj kev txwv cua sov, tus neeg teb xov tooj tau ua tiav kwv yees li 60 feem pua txuag hauv kev txiav tawm - ntsig txog lub sijhawm rig. Kev lag luam xaim hluav taws xob txiav hluav taws xob, muaj nuj nqis kwv yees li $ 14.8 nphom hauv xyoo 2025, txuas ntxiv hloov mus rau lub raj mis-HP dawb cov kev daws teeb meem raws li kev ua haujlwm drilling hauv ultra- dej tob thiab siab - lub zog reservoirs nthuav dav thoob ntiaj teb.
Hom kev nco thiab ncua sij hawm muaj peev xwm
Kev ua haujlwm ntawm lub cim xeeb tso cai rau VUPT kom tau txais cov ntaub ntawv rau lub sijhawm txuas ntxiv yam tsis muaj kev sib txuas ntawm qhov chaw, ua rau nws tsim nyog rau cov qhov dej uas slickline lossis coiled tubing kev cuam tshuam yog nyiam tshaj ntawm cov xov tooj. Lub peev xwm 512 MB lub peev xwm txhawb nqa ntau- teev cov kev txiav txim siab ntau lawm ntawm tag nrho cov ntsuas ntsuas ntsuas ntsuas tus nqi. Cov ntaub ntawv retrieval thiab cov ntaub ntawv pov thawj zoo yog ua tom qab lub cuab yeej rov qab, nrog rau cov ntaub ntawv kaw, qhov kub thiab txias, ntws, thiab tuav cov ntaub ntawv tuaj ncaj qha rau hauv cov qauv kev tshuaj ntsuam xyuas software. Nrog rau ultra-HP / HT kev ntsuam xyuas txuas ntxiv tshaj 200 degrees Celsius, lub raj mis -VUPT dawb sawv cev rau cov kev daws teeb meem txhim khu kev qha rau kev txiav ntoo hauv lub ntiaj teb qhov nyuaj tshaj plaws downhole ib puag ncig.
