Ubhontshisi uminyanisa ukuminyanisa okungaguquki okusetshenziselwa ukulawula ukugeleza koketshezi.Ubhontshisi ominyiwe uqukethe ubhontshisi oshintshwayo ngokuvamile owenziwe ngensimbi eqinile.Ubhontshisi ominyiwe ubekwe eduze kwesihlahla sikaKhisimusi, okuyisethi yamavalvu nokufakwa phezulu komthombo ukulawula ukukhiqizwa noma ukugeleza.Ubhontshisi uminyanisa ukhiqizwa ngokunembile ububanzi bokuminyanisa futhi lonke uketshezi lugeleza kuwo.Amabhontshisi aminyanisiwe atholakala ngamasayizi ahlukene futhi abonakala ngokuminyanisa ububanzi.
Nquma ubhontshisiivamise ukusetshenziswa ku-valve yokuklinya ephozithivu ukulawula ukugeleza, i-Aseeder yokuminyanisa ubhontshisi iyafana nohlobo lwe-Cameron H2 big john choke bean, umzimba Impahla: 410SS, efakwe i-Tungsten Carbide (C10 noma i-C25) , ukuze ivikeleke ekugqokeni okubolayo nokulimazayo. .
Ngakolunye uhlangothi lwenqwaba yokuklinywa, ubhontshisi obukaliwe obulinganisiwe usetshenziswa ukulawula izinga lokugeleza ngebhokisi lokuklinywa elingashintshi.Ubhontshisi ngamunye uwububanzi obuthile, imvamisa ekuthwesweni kweziqu ze-1/64-132 inch, Ngokuya ngohlobo lwemishini esetshenzisiwe, ubukhulu bobhontshisi obuncitshiwe bungaba ngamasentimitha amathathu.
Singenza ukwelashwa kwe-QPQ emzimbeni kabhontshisi ominyanisayo, ukuthuthukisa ubulukhuni obungaphezulu.
Isiqu sokuminyanisa nesihlalo yizingxenye ezibalulekile zamavalvu okuklinywa alungisekayo kumishini ye-wellhead.Ihlanganiswe namathiphu we-tungsten carbide nomzimba we-SS410.
Ubhontshisi oyiminyanisa usetshenziswa embonini kawoyela negesi futhi uwusizo kakhulu ngezizathu eziningi.
•Ubhontshisi ominyiwe ugcina futhi ulawula izinga lokukhiqizwa kwe-hydrocarbon emthonjeni.
•I-coke beans isetshenziselwa ukuvimbela ukungena kwesihlabathi kuye ngokuthi hlobo luni lwe-reservoir rock.
•Ubhontshisi ominyiwe usetshenziselwa ukuthola ingcindezi ezansi nobhontshisi
•Ivimbela ukugeleza kwamanzi kusenesikhathi noma ukuhlangana
•Ingasetshenziswa emithonjeni yokuphakamisa igesi yokwenziwa
Ukuminyanisa, kungakhathaliseki ukuthi kukuphi, kudala ingcindezi emuva emthonjeni.Lokhu kubangela ukucindezela okuphezulu phansi komthombo.I-Choke bean ivame ukusetshenziswa ku-valve yokuminyanisa ukuze ulawule ukugeleza.Ngakolunye uhlangothi lokuminyanisa okuhlukahlukene, ubhontshisi okhiniweyo olinganisiwe ulawula izinga lokugeleza ngokuklinywa okugxilile.Amabhontshisi aminyanisiwe ajikijelwa ebhokisini lokuminyanisa futhi anobubanzi obuthile, ngokwezigaba ze-1/64".
