Uyini umehluko phakathi kweCast Iron Bridge Plug, Composite Bridge Plug kanye neDissolvable Bridge Plug?

Izincazelo Eziningiliziwe
1. Ipulaki Lebhuloho Lensimbi Ecijile (Ihhashi Lomsebenzi Lendabuko)

• Kuyini: Uhlobo lokuqala noluhlala njalo lwepulaki yebhuloho. Lwakhiwe ngensimbi ephonswe kanye nezinye izingxenye zensimbi.
• Indlela esebenza ngayo: Ifakwa ebhokisini kusetshenziswa ipayipi lentambo, ipayipi, noma ipayipi lekhoyili. Uhlelo lwe-slip-wedge luthinta insimbi ingena odongeni lwebhokisi, bese izinto zokupakisha ziyanwetshwa ukuze kudalwe uphawu olungenagesi.
• Umehluko Oyinhloko: Ohlala Njalo Futhi Oqinile Kakhulu. Inzuzo yayo eyinhloko amandla ayo amakhulu okucindezela nokuthamba. Yenzelwe ukuba yibhlokhi ehlala njalo, ebheke ngakwesokudla.
• Ukususwa: Kungasuswa kuphela ngokusila (ukusigaya ngethuluzi elikhethekile lokudonsa phansi). Lena inqubo ethatha isikhathi eside, ebiza kakhulu edinga umshini wokubhoboza futhi idala inani elikhulu lemfucumfucu yensimbi okumele isakazwe iphume emgodini.
• Okuhle Kakhulu Ku:

1. Ukushiywa komthofu unomphela.
2. Izimo lapho kudingeka khona isithiyo esiphelele nesingenakunqotshwa ukuze kuphephe.
3. Ukuhlukanisa izindawo ezinezingcindezi eziphakeme kakhulu.

2. I-Composite Bridge Plug (Indinganiso Yesimanje “Yokubhoboza”)

• Kuyini: Ipulaki yebhuloho elenziwe ngezinto ezihlanganisiwe ezenziwe ngobunjiniyela—ngokuvamile ingxube yemicu yengilazi, imicu yekhabhoni, kanye nama-resin.
• Indlela esebenza ngayo: Isebenza ngendlela efanayo nepulaki yensimbi ephonswe ngokusetha imishini (iziliphu, izinto zokupakisha). Kodwa-ke, izinto zokwakha zilula kakhulu futhi kulula ukuzibhoboza.
• Umehluko Oyinhloko: Kulula Ukubhoboza. Lena yinhloso yayo eyinhloko. Izinto ezihlanganisiwe ziqine ngokwanele ukubamba ingcindezi enkulu ngesikhathi sokusebenza kodwa ziqhekeka ngamabomu, okusho ukuthi ziqhekeka kalula ngaphansi kwamandla omshini we-drill bit.
• Ukususwa: Kususwa ngokubhoboza noma ngokugaya. Inqubo ishesha kakhulu kunokugaya insimbi ephonswe ngensimbi. Imfucumfucu iyimpuphu encane, engeyona eyensimbi, futhi engagugi okulula kakhulu ukuyihlanza ebhodweni, okunciphisa ingozi yokulimaza imishini engezansi komfula.
• Okuhle Kakhulu Ku:

1. Ukuqhekeka kwe-hydraulic okunezigaba eziningi (“i-Fracking”) emithonjeni evundlile. Amaningi ala ma-plug ahlelwe ukuhlukanisa izigaba, bese ebholwa wonke ngokusebenza okukodwa okuphumelelayo.
2. Ukuhlukaniswa kwesikhashana kwendawo yokuhlola noma yokukhiqiza.
3. Noma yisiphi isimo lapho wazi khona ukuthi kuzodingeka ususe ipulaki bese uqala kabusha ukubhoboza noma ukukhiqiza.

3. Ipulaki Yebhuloho Elincibilikayo(Ukuqamba Okusha “Okuhleliwe Nokukhohlwa”)

• Kuyini:Uhlobo oluthuthuke kakhulu, olwenziwe ngezinsimbi (njenge-magnesium noma i-aluminium alloys) noma ama-polymer aklanyelwe ukuncibilika ngendlela ebikezelwayo lapho evezwa uketshezi oluthile olunezimbobo, izinga lokushisa, kanye nengcindezi.
• Indlela esebenza ngayo:Isethwe njenganoma iyiphi enye ipulagi. Umehluko yilokho okwenzekayongemvaumsebenzi wayo usuphelile. Upompa uketshezi oluthile (isib. i-brine noma i-asidi) noma umane ulinde uketshezi lwemithombo yemvelo ukuthi luqale inqubo yokuncibilika.
• Umehluko Oyinhloko: Akukho Ukungenelela Okudingekayo Ukuze Kususwe.Ipulaki iyanyamalala yodwa ngokoqobo, ishiyei-wellbore evulekile.
• Ukususwa:Itiyancibilikisangamakhemikhali esikhathini esinqunyiwe kusengaphambili (isb., amahora, izinsuku, amasonto). Izinga lokuncibilika lakhiwe ngokusekelwe kumakhemikhali oketshezi kanye nokushisa okuphansi.
• Okuhle Kakhulu Ku:
  • Izinhlelo zokusebenza ezidlulelelapho ukungenelela (isib. ukuthumela intambo yokubhoboza) kubiza kakhulu, kuyingozi, noma akunakwenzeka (isib., imithombo emide kakhulu eseceleni, ukuqedwa kolwandle).
  • Imithombo eneAmaphampu Kagesi Angena Ngaphansi Komhlaba (ama-ESP), lapho ngisho nofulawa ocolekile ovela kuma-plug ahlanganisiwe ungalimaza iphampu. I-plug encibilikisiwe ayishiyi mfucumfucu.
  • Ukuqedwa “kwe-Frac-and-flow” lapho abakhiqizi befuna ukuqala ukukhiqiza ngokushesha ngemva kokuqhekeka ngaphandle kokusebenza kokubhoboza.

Ithebula Lokuqhathanisa

I-Landrill iyakhiqiza futhi ihlinzeka ukusebenza okuphezuluama-frac plug ancibilikayo ukukusiza ukunciphisa isikhathi sokuqedafuthi wonge izindleko.
