Kunzwisisa Mabasa eCasing Head Assemblies mu Wellhead Equipment

Mukushanda kwemafuta uye gasi mutsime,casing head assemblieskuita basa rakakosha mukuona kuchengetedzeka uye kugona kwemaitiro ekugadzira. Ichi chikamu chakakosha chewellhead equipmentyakagadzirirwa kupa tsigiro yetambo yekasi uye nekusimbisa annulus pakati pecasing netsime. Kunzwisisa seicasing head assemblybasa rakakosha kune chero munhu ari muindasitiri yemafuta uye gasi.

 The casing head assemblyinowanzoiswa pamusoro pekasi yetsime uye inoshanda senzvimbo yekubatanidza yezvikamu zvakasiyana zvemidziyo yemutsime. Iyo ine akati wandei makiyi zvikamu, zvinosanganisira casing head, casing spool uye casing hanger. Musoro wecasing ihombe, inorema-basa chikamu chinosungirirwa kumusoro kwegomba retsime. Inopa imba ye casing spool uye inoshanda serutsigiro rwehuremu hwetambo yekasi.

A casing spool, kune rumwe rutivi, icylindrical mudziyo wakasungirirwa pamusoro pemusoro wecasing. Inopa nzira yekuchengetedza iyo casing hanger uye kugadzira chisimbiso pakati pekasi uye tsime. Iyo casing hanger chinhu chakakosha chinotsigira huremu hwetambo yekasi uye inopa chisimbiso kudzivirira zvinwiwa kubva mutsime.

Rimwe remabasa ekutanga e-casing head assembly ndeyekupa hukama hwakachengeteka uye hwakavimbika pakati petambo yekasi uye musoro wetsime. Kubatana uku kwakakosha kuchengetedza kutendeseka kwetsime uye kudzivirira kubuda kweoiri, gasi rechisikigo kana zvimwe zvinwiwa. Iyo casing head assembly inopawo nzira yekumisa tambo ye casing mukati metsime uye inobvumira kuisirwa kwezvimwe zvinhu zvakakosha zvakadai sezvidziviriro zvinoputika uye miti yekugadzira.

Pamusoro pekupa tsigiro yetambo yecasing, iyo casing head assembly inoitawo basa rakakosha mukuita simende. Mushure mekunge tambo yekasi yaiswa, simende inoputirwa mukati megore pakati pekasi uye tsime kuti igadzire chidziviriro chekuchengetedza uye kudzivirira mvura kuti isafambe pakati peakasiyana geological maumbirwo. Iyo casing head assembly inopa nzira yekupinza simende slurry mu annulus uye inova nechokwadi chekuti simende slurry inogoverwa zvakaenzana kutenderedza tambo yekasi.

Uyezve,casing head assemblieszvakagadzirirwa kugonesa kuiswa kwemhando dzakasiyana dzemidziyo yemusoro wemvura, senge mavharuvhu, makachipa, uye geji dzekumanikidza. Izvi zvikamu zvakakosha pakudzora kuyerera kwemvura mutsime uye kutarisa downhole kudzvanywa uye tembiricha mamiriro. Iyo casing head assembly inopa yakachengeteka uye inosvikika nzvimbo yekumisikidzwa kweichi midziyo, ichibvumira yakachengeteka uye inobudirira tsime kushanda.

Kupfupisa, gungano remusoro wecasing chinhu chakakosha chemidziyo yematsime uye inoita basa rakakosha mukuchengetedza uye kushanda kwakanaka kwematsime emafuta negesi. Masangano emusoro weCasing anovimbisa kutendeseka uye kubudirira nekupa rutsigiro rwetambo yekaseji, kugadzira chisimbiso pakati pecasing uye tsime, uye kugadzirisa kuisirwa kwemidziyo yakakosha yemusoro. Kunzwisisa mashandiro anoita macasing head assemblies kwakakosha kune chero munhu ane chekuita nekugadzira, kuvaka kana kushanda kwematsime emafuta negesi.
