✧ Inkcazo
I-Flowhead - umthi wovavanyo lomphezulu uneevalve ezine zesango: ivalve eyintloko, iivalve ezimbini zamaphiko, kunye nevalve yokuswabha. Ivalve yephiko lokuphuma iyavulwa kwaye ivalwe kusetyenziswa i-hydraulic actuator. Ngaphezulu kwevalve yeswab kukho i-subassembly ephakamisayo (engaphantsi) enoqhagamshelo olunemisonto. Udibaniso olunentambo ludla ngokubizwa ngokuba lumanyano olukhawulezayo. Umanyano olukhawulezayo lusetyenziselwa ukudibanisa izixhobo zoxinzelelo ezincedisayo ezifunekayo ukuba izixhobo ziza kuqhutyelwa phantsi. Ezinye ii-flowheads zinesakhelo sokukhusela esibotshwe kwibhloko engundoqo ukuthintela umonakalo kwiivalvu ngexesha lokuphatha. Ngaphantsi kwe-swivel yokuzikhethela kukho i-asembly yevalve eyintloko kunye nezantsi esezantsi. Ukuze kunyuswe kwaye kuthotywe intambo yovavanyo lwe-drill stem (DST), ii-elevator (i-clamps) zincanyathiselwe kwi-flowhead.
Iiyunithi eziphezulu kunye nezisezantsi zihlanganiswe nomthwalo othwala umanyano olukhawulezayo ukulungiselela ukudibanisa kunye nokuqhaqha. Amacandelo aquka i-handing sub, ivalve yesango yeswab ephezulu, ivelufa yokhuseleko ekude, umgca wokuhamba kunye neendawo zokubulala. Izixhobo ezikhethiweyo ziquka impompo yesandla okanye iyunithi yokulawula i-hydraulic, indlela yokusika i-wireline kwi-valve ye-swab, i-adapter ye-wireline kunye nebhasikithi yokuthutha.
I-Flowhead iyona nto iphambili yokulawula iqula kunye nokuvumela ukungeniswa kwe-wireline, esetyenziselwa ukulawula uxinzelelo lwangaphezulu kunye nokunyakaza kwamanzi kunye negesi ngexesha lokuvavanya i-drill stem, kunye nokulula ukukhulula ukubunjwa phezu koxinzelelo ngexesha elifutshane ekuqaleni kokuvula kakuhle. Ingabonisa intshukumo yokwenyani yolwelo kuvavanyo loxinzelelo oluphezulu njengokumelana okuncinci kolwelo, akukho lula ukubhloka. Kwaye i-flowhead igcwele izixhobo zokukhawulelana nezixhobo ngokutyibilikayo. Xa ngexesha lovavanyo lwe-drill stem, umsebenzi we-Acid, i-Job ye-fracture, umsebenzi we-Stege cementing, umsebenzi wokulungisa ngokutsha unokucutshungulwa ngaphandle kokuphakamisa umtya, unokwenza umsebenzi usebenze ngakumbi, ukunciphisa ixesha lokusebenza.
