Yintoni umahluko phakathi kweCast Iron Bridge Plug, Composite Bridge Plug kunye neDissolvable Bridge Plug?

Iinkcazo ezineenkcukacha
1. Iplagi yeBhulorho yentsimbi (ihashe lomsebenzi lendabuko)

• Yintoni: Uhlobo lokuqala noluhlala luhleli lweplagi yebhulorho. Yakhiwe ngentsimbi ephosiweyo kunye nezinye izinto zentsimbi.
• Indlela esebenza ngayo: Ifakwa kwikhava kusetyenziswa intambo, ityhubhu, okanye ityhubhu yekhoyili. Inkqubo yokutyibilika kwentsimbi ithintela isinyithi singene eludongeni lwekhava, kwaye izinto zokupakisha ziyandiswa ukuze zenze isitywino esingangenisi gesi.
• Umahluko oPhambili: Uhlala Uhleli kwaye Unamandla Kakhulu. Inzuzo yayo ephambili kukuqina kwayo okukhulu kokucinezela nokutsalwa. Yenzelwe ukuba ibe yibhloko ehlala ihleli, ecalanye.
• Ukususwa: Kungasuswa kuphela ngokusila (ukusila ngesixhobo esikhethekileyo somngxuma ongaphantsi komhlaba). Le yinkqubo ethatha ixesha elide, ebiza kakhulu efuna isixhobo sokugrumba kwaye idala inani elikhulu lenkunkuma yesinyithi ekufuneka ijikeleziswe iphuma equleni.
• Eyona ilungileyo:

1. Ukushiywa komngxuma osisigxina.
2. Iimeko apho kufuneka umqobo opheleleyo nongaphosisiyo ukuze kukhuseleke.
3. Ukuzahlula iindawo ezineenguqu zoxinzelelo oluphezulu kakhulu.

2. Iplagi yeBridge edityanisiweyo (Umgangatho wanamhlanje "onokubhobozwa")

• Oko kukuko: Iplagi yebhulorho eyenziwe ngezinto ezidityanisiweyo ezenziwe ngobunjineli—ngesiqhelo umxube wemicu yeglasi, imicu yekhabhoni, kunye neeresini.
• Indlela esebenza ngayo: Isebenza ngendlela efanayo neplagi yesinyithi xa kuthelekiswa neendlela zokuseta (iziliphu, izinto zokupakisha). Nangona kunjalo, izixhobo zilula kakhulu kwaye kulula ukuzigqobhoza.
• Umahluko oPhambili: Inokugqobhoka ngokulula. Le yeyona njongo yayo iphambili. Izinto ezidityanisiweyo zomelele ngokwaneleyo ukubamba uxinzelelo olukhulu ngexesha lokusebenza kodwa ziqhekeka ngabom, oko kuthetha ukuba ziyaqhekeka lula phantsi kwamandla oomatshini e-drill bit.
• Ukususwa: Kususwa ngokubhoboza okanye ngokusila. Le nkqubo ikhawuleza kakhulu kunesinyithi esisikiweyo. Inkunkuma yimpuphu ecolekileyo, engenasinyithi, kwaye ayirhawuzeli lula ukuyicoca iphume emngxunyeni wequla, nto leyo enciphisa umngcipheko wokonakalisa izixhobo ezisezantsi.
• Eyona ilungileyo:

1. Ukuqhekeka kwe-hydraulic okunezigaba ezininzi (“Fracking”) kwimingxuma ethe tye. Amaninzi ezi plugs amiselwe ukwahlukanisa izigaba, aze emva koko agqojwe onke ngokusebenza okukodwa, okusebenzayo.
2. Ukwahlulwa kweendawo okwexeshana ukuze kuvavanywe okanye kuveliswe.
3. Nakweyiphi na imeko apho uyaziyo ukuba kuya kufuneka ususe iplagi uze uqalise ukubhola okanye ukuvelisa.

3. Iplagi yeBridge enyibilikayo(Ubuchule "Bokubeka-kwaye-Ulibale")

• Yintoni:Uhlobo oluphambili kakhulu, olwenziwe ngeesinyithi (ezifana ne-magnesium okanye i-aluminium alloys) okanye ii-polymers ezenzelwe ukunyibilika ngendlela eqikelelweyo xa zibekwe kulwelo oluthile olunemibhobho, ubushushu, kunye noxinzelelo.
• Ingaba isebenza kanjani:Isetwe njengayo nayiphi na enye iplagi. Umahluko kukuba kwenzeka ntoniemvaumsebenzi wayo ugqityiwe. Upompa ulwelo oluthile (umz., ityuwa okanye i-asidi) okanye ulinde nje ukuba ulwelo lwemithombo yendalo luqalise inkqubo yokunyibilika.
• Umahluko oPhambili: Akukho ngenelelo lufunekayo ukuze kususwe.Iplagi iyanyamalala ngokwayo, ishiyei-wellbore evulekileyo.
• Ukususwa:Yonaiyanyibilikangokweekhemikhali kwixesha elimiselweyo (umz., iiyure, iintsuku, iiveki). Izinga lokunyibilika lenziwe ngokusekelwe kwikhemikhali yolwelo kunye nobushushu bomngxuma ongaphantsi.
• Eyona ilungileyo:
  • Izicelo ezigqithisileyoapho ukungenelela (umz., ukuthumela umtya wokubhoboza) kubiza kakhulu, kuyingozi, okanye akunakwenzeka (umz., amaqula amade kakhulu asecaleni, ukugqitywa kwamanzi angaphantsi kolwandle).
  • Imithombo kunyeIimpompo zombane ezintywiliselwa emanzini (ii-ESP), apho nomgubo ocolekileyo ovela kwiiplagi ezidityanisiweyo unokonakalisa ipompo. Iplagi enyibilikisiweyo ayishiyi nkunkuma.
  • Ukugqitywa "kwe-Frac-and-flow" apho abavelisi bafuna ukuqala imveliso kwangoko emva kokuqhekeka ngaphandle komsebenzi wokugrumba.

Itheyibhile yokuthelekisa

IiLandrill ziyavelisa kwaye zibonelela ukwenza okuphezuluiiplagi ze-frac ezinyibilikayo ukukunceda ukunciphisa ixesha lokugqibakwaye wonge iindleko.
