Raws li ib qho tseem ceeb infrastructure rau natural gas ncov shaving thiab muab kev ruaj ntseg, kev ua hauj lwm kev nyab xeeb ntawm ntsev cavern gas cia chaw yog ncaj qha mus rau lub stability ntawm lub zog mov. Thaum cov roj txhaj tshuaj thiab tsim khoom hauv cov chaw cia khoom, cov teeb meem suav nrog kev hloov pauv kev ntxhov siab, roj-kev hloov pauv hauv dej, thiab caprock sealing kev ua tau zoo ua rau cov kev xav tau siab heev ntawm kev soj ntsuam cov thev naus laus zis. Distributed optical fiber sensing thev naus laus zis qhia tau hais tias qhov tshwj xeeb zoo nyob rau hauv ntsev cavern gas cia vim nws qhov ntev - lub sij hawm, txuas ntxiv thiab faib kev saib xyuas muaj peev xwm.
Nyob rau hauv lub qhov dej ntsev qhov dej cia ntawm Huabei Oilfield, ZITN Microelectronics tau txais ib qho kev sib txuas sab nraud -txheej txheej txheem kho qhov muag fiber ntau, txhim kho Φ6.35 mm steel tube optical cables mus rau sab nraud ntawm txoj hlua tubing kom ua tiav ntev - lub sijhawm ntsuas kub zoo li qub. Ntawm cov ntsiab lus nkag ntawm cov khoom siv ntawm cov khoom siv kho qhov muag, kev kho qhov muag fiber ntau splicing thiab encapsulation pup pob qij txha tau siv los xyuas kom meej qhov kev ntseeg tau thiab sealing kev ua tau zoo ntawm downhole cable.
Thaum lub sijhawm saib xyuas, DTS system khaws cov ntaub ntawv tiag tiag -lub sijhawm ntsuas kub ntawm lub qhov dej tag nrho, thiab thim rov qab cov pa roj- qhov chaw sib txuas dej thiab cov kev hloov pauv hloov pauv hauv cov roj cia muaj peev xwm los ntawm kev hloov pauv kub. Lub DAS system synchronously soj ntsuam acoustic signals nyob rau hauv lub wellbore los txheeb xyuas caprock micro- leakage thiab wellbore integrity anomalies. Txij li thaum kev teeb tsa, lub kaw lus tau ua haujlwm tsis tu ncua thiab ruaj khov, muab cov ntaub ntawv tseem ceeb rau kev ua kom zoo ntawm kev txhaj tshuaj- cov txheej txheem tsim khoom thiab kev ua haujlwm nyab xeeb ntawm cov chaw cia roj.
Tsis tas li ntawd, ZITN kuj tau tsim cov cuab yeej ntsuas ntsuas ntsuas qhov ntsuas siab rau cov roj cia txhaj - cov qhov dej tsim tawm. Los ntawm kev ywj pheej xa cov kab hluav taws xob kho qhov muag hauv cov tubing thiab sib txuas kev sib koom ua ke ntawm DTS thiab DAS, thev naus laus zis tau txheeb xyuas cov ntsiab lus ntawm cov dej ntws tawm thiab cov kev sib txuas. Cov ntawv thov hauv ntau lub qhov dej tso roj tau txheeb xyuas qhov ntev - kev ntseeg siab ntawm cov thev naus laus zis no nyob rau hauv kev hloov kev ntxhov siab.
