Yintoni iCasing Collar Locator(CCL)?

I-casing-collar locator (CCL) sisixhobo esibalulekileyo esisetyenziselwa ukulawula ubunzulu kwimisebenzi yokugawulwa kwemigodi. Xa idityaniswe ne-gamma ray log, ivumela ulungelelwaniso lokugawulwa kwemithi enomngxuma ovulekileyo, ivumela ukuchongwa okuchanekileyo kweeyunithi okanye iindawo zokugcina amanzi. Olu lungelelaniso lubalulekile kwimisebenzi elandelayo yokuhlisa umngxuma njengokugqobhoza. Ngenxa yokubaluleka kwayo ekuboneleleni ngolawulo olunzulu olungundoqo, i-CCL ibandakanyiwe phantse kuwo wonke umtya wesixhobo secased-hole.

Isixhobo ngokwaso siquka i-coil-and-magnet ilungiselelo kunye ne-downhole amplifier. Eyona nto ibuthathaka kakhulu kula malungiselelo ibandakanya iipali zemagnethi ezijonge ngokufanayo ezibekwe macala omabini ekhoyili esembindini. Njengoko isixhobo sidlula indawo apho i-casing metallic yandiswa yikhola, imigca yamagnetic ye-flux iphazamisekile, ibangela utshintsho kwintsimi yamagnetic ejikeleze ikhoyili kunye nokunyanzeliswa kwangoku ngaphakathi kwayo. Olu phawu luye lwandiswa kwaye lurekhodwe kumphezulu njenge-voltage spike, eyaziwa njengekhola "ukukhaba."

Ii-CCLs zinokuqhutywa kwimowudi yokugawulwa kwe-wireline eqhelekileyo okanye kwi-slickline, kunye nokhetho lwee-CCL zememori ecocekileyo, ezirekhoda idatha ngaxeshanye nezinye izixhobo zokugawulwa kwemithi, kunye nezixhobo zexesha lokwenyani, eziguqula i-voltage spike ibe yi-tension spike kumphezulu. ukubhaqwa. Kwizicelo zetyhubhu ezidityanisiweyo, ii-CCLs ziye zahlengahlengiswa ukuze zidlulise i-spikes yoxinzelelo ngolwelo olungaphakathi kwityhubhu ephothiweyo ukuya kumphezulu, njengoko ubunzima bomtya odityanisiweyo wetyhubhu bukwenza kube nzima ukubhaqa ii-spikes zoxinzelelo ezincinci ngokuzithemba. Ukuqhubela phambili kwamva nje kuphuculwe ezi zixhobo zoxinzelelo oluphezulu / ubushushu obuphezulu.

Ukongeza, iintlobo ezithile zeetrektara zokuhlisa imingxuma ezisetyenziswa kumaqula atenxileyo ziyakwazi ukuvelisa i-CCL ngexesha lokusebenza kwazo, zibonelela ngobunzulu obufanayo bokulawula ukusebenza. Ukuba unomdla kwi-Vigor's Casing Collar Locator okanye enye i-drilling, ukugqitywa, izixhobo zokugawula i-oyile kunye ne-gas industry, nceda unganqikazi ukuqhagamshelana nathi ngolwazi olungakumbi lobugcisa.
