Isikhokelo Esipheleleyo kwiiKlasi zePacker V6-V0 (Icandelo 1): Ukuqonda iKhowudi yokuHlela ye-Downhole “Sealing Guardians” ngokweMbono ye-API 11D1 Standard

"Kwindawo yokulwa engaphantsi komhlaba" yokutsalwa kweoyile negesi,abapakishi"zii-sealing guards" ezikhusela ukhuseleko lwe-wellbore. Zingahlula uxinzelelo lwee-formations ezahlukeneyo, zithintele ukuhamba kwamanzi, kwaye zixhase imithwalo yentambo, zisebenza njengezixhobo eziphambili ukuqinisekisa uzinzo lwenkqubo yonke yokugrumba, ukugqitywa kwemithombo, kunye nemveliso yeoyile. Nangona kunjalo, iimeko ze-downhole ziyahluka kakhulu: eminye imithombo inobushushu obungama-degrees Celsius angamashumi kuphela, ngelixa eminye idlula ama-200°C; eminye inoxinzelelo oluzinzileyo, ngelixa eminye ifumana ukuguquguquka rhoqo; eminye iqulethe ioyile ekrwada eqhelekileyo, ngelixa eminye ibamba "izilwanyana" ezikrwada ezifana ne-hydrogen sulfide (H₂S).

Umgangatho we-API 11D1 weZixhobo zeDownhole kwiShishini lePetroleum neGesi yendalo – IiPackers kunye neeBridge Plugs zicacisa ngokucacileyo ukuba iiklasi zepacker ziyanda kwinqanaba lokusebenza ukusuka kwi-V6 ukuya kwi-V0: okukhona inani lincinci, kokukhona iimfuno zokusebenza ziqinile. I-V6 "linqanaba lokungena elisisiseko," kwaye i-V0 "linqanaba lokugqibela lokusebenza," apho iklasi nganye ihambelana nemigangatho yovavanyo ecacileyo kunye neemeko ezifanelekileyo.

Namhlanje, siza kukunceda ucacise umahluko ophambili phakathi kwezi klasi zisi-7 kwaye uphephe iingcamango eziphosakeleyo ekukhetheni iipakethi.

I-Core Logic yoHlelo lweeKlasi kwi-API 11D1

Abantu abaninzi bayabhidanisa ukulandelelana kweeklasi zokupakisha. Ingongoma ephambili ekufuneka ikhunjulwe kukuba uyilo lweklasi lwe-API 11D1 lulandela umgaqo othi “okukhona inani lincinci, kokukhona uvavanyo lubanzi ngakumbi.” Ukwanda kwinqanaba leklasi kuthetha ukuba izinto zokuvavanya zongeza kancinci kancinci iimeko ezingqongqo (ezifana nokujikeleza kobushushu, imithwalo ye-axial, ukuvalwa kwegesi, kunye neendawo ezirhabaxa) kuvavanyo lokuqala olulula lokuvala oluzinzileyo.

Eyona nto iphambili kolu hlu "kukulingana ngokwemfuno" - akugcini nje ngokuthintela inkcitho yeendleko ebangelwa kukusebenzisa izixhobo ezikumgangatho ophezulu kwimithombo eqhelekileyo kodwa kukwathintela neengozi zokhuseleko ezibangelwa kukusebenzisa izixhobo ezikumgangatho ophantsi kwimithombo egqithisileyo.
