Mhando dzeBridge Plugs

Mabhurogi maturusi maturusi ekudzika akaiswa kuti atsaure chikamu chepasi chegomba. Mapulagi ebhiriji anogona kunge ari echigarire kana kudzoserwa, zvichiita kuti chibhorani chepasi chivharirwe zvachose kubva mukugadzirwa kana kuvharirwa kwenguva pfupi kubva pakurapwa kunoitwa kunzvimbo yepamusoro. Iwo anoumbwa nematehwe, mandrel, uye elastomers (kuisa chisimbiso zvinhu).
Mhando dzebhiriji Plugs
Sezvambotaurwa pamusoro apa, mabhiriji plugs anogona kuva;
Retrievable Bridge Plugs (RBP) kana Temporary Bridge Plugs.
Permanent Bridge Plugs (PBP) kana Millable/Drill-Through Bridge Plugs.
Retrievable Bridge Plugs (RBP)
Aya ndiwo mapulagi akanyanya-kudzvanywa emultizone uye anosarudza nzvimbo imwe chete mashandiro akadai se acidizing, fracturing, cementing, uye kuyedza. RBPs inogona kuiswa mukunetsana kana kudzvanywa. Ivo vanogona zvakare kusetwa isina kudzika mune isina kutsigirwa casing kuti ive nekumanikidza uchishanda pamidziyo yemusoro.
MaRBP anogona kusetwa mukunetsana izvo zvinoita kuti ive yakanakira kuseta isina kudzika yekuyedza tsime midziyo uye zvakare kudzika kuyedza-yakanyanya-kudzvanywa matsime. Inoratidzira yakakura yemukati by-pass kuderedza swabbing paunenge uchimhanya uye uchidzosa. Iyo by-pass inovhara panguva yekumisikidzwa kweplugs uye inovhura isati yaburitsa ekumusoro masipidhi kuenzanisa kudzvanywa kana usingaise. Iyo by-pass inowanikwa zvakananga pazasi pemasevhisi epamusoro kubatsira kugeza marara kana by-pass yakazaruka. Mapulagi ebhiriji anogona kudzoserwa anogona kushandiswa pakusiya basa kwekanguva kana kuti tandem nemapaki ebasa anogona kudzoserwa kuitira kugadzirisa.
Permanent Bridge Plugs (PBP) kana Millable/Drill-Through Bridge Plugs
Aya ndiwo mapulagi emabhiriji akagadzirwa / akagadzirwa kuti avhare kana kupatsanura chikamu chetsime zvachose. Iwo anowanzo kugadzirwa nesimbi inogayiwa saka iwo anonziwo drill through kana millable permanent bridge plugs.
Permanent bhiriji plugs akakodzera kune inovhuvhuta kemikari kana yakavava gasi nharaunda. PBP inogona kumira kumanikidzwa kubva pa10,000psi kusvika pamusoro pe15,000psi uye tembiricha yepamusoro ye327°C (638°F) uye tembiricha ye205°C (400°F).
Bridge Plugs Seiling Elements (Swellable Elastomers)
Mapuragi emabhiriji ane chinhu chinogomara chinoshandiswa kugadzira chisimbiso pamadziro echibhorani chakatenderedza. Kana ichiiswa, chinhu chinogomara chingada kupfuura nepachidziviso chidiki pane dhayamita yechibhorani panofanira kusetwa chinhu. Nekuda kweizvozvo, iyo yakaremara element saizi inogona kudzikiswa nediki dhayamita inodzivirirwa iyo yainozoisa. Kana yangoiswa panzvimbo yaidiwa, chinhu chinogomara chinogona kuiswa nekutsikirirwa, inflation, kana kuzvimba zvichienderana nerudzi rwechinhu chinoshandiswa. Zvinhu zvinozvimba zvinotora nguva yakati rebei (semuenzaniso, mazuva akati wandei) kuzvimba pamberi pechinhu chinobatidza, uye zvinhu zvinozvimba zvinogara zvichiwedzera nguva yakawandisa. Kana iyo inflatable element inoshandiswa, inoisa munzvimbo yakadonha uye yobva yawedzera kana yakamira zvakanaka. Nehurombo, iyo inflatable element inogona kukuvadzwa, inogona kunetsa kuita, uye inogona kukanganiswa nekuchinja kwekupisa kwe downhole.
Nenzira yakajairwa, mapulagi anoshandisa compression set element ine sleeve inodzvanywa kuwedzera dhayamita yechinhu kuita chisimbiso. Kudzvinyirira zvinhu zvakadaro zvinogona kuda simba guru uye sitiroko yakareba.
Zvisimbiso zvakaiswa paBridge plugs zvinoenderana nezvivakwa zvetsime, mhando yemvura yetsime, tembiricha uye kudzvanywa kwetsime.

Zvishandiso zveBridge Plugs
Bridge plugs anowanzo shandiswa kune zonal kuparadzaniswa kwezvikamu zvakasiyana zvetsime. Plugi yebhiriji inogona kuiswa panzvimbo kuitira kuti iite basa rekushanda kana kupindira pane chimwe chikamu chetsime. Kumisikidza plug yebhiriji munzvimbo kunobatsira kuwana akawanda-zonal yekuzviparadzanisa nevamwe kuti iite nemazvo mashandiro pane yakasarudzika chikamu chetsime pasina kukanganisa zvimwe zvikamu.
Mabhurogi plugs anoshandiswawo plugging uye kusiya mabasa. Kana huwandu hwe hydrocarbon mudhamu isingachatengeseki kana vhoriyamu yedhamu yadirwa kuburikidza nekugadzirwa, kukosha kwekusiya tsime kunomuka. Mugadziri wematsime anogona kusarudza kuseta maplug ebhiriji akabatana nesamendi slurries kuti ave nechokwadi chekuti simende yakakwira haidonhe mutsime. Kana zvakadaro, plug yebhiriji yaizogadzikwa uye simende inopomba pamusoro pepuragi kuburikidza nepipe yekuboorera, uyezve pombi yekuboorera yobviswa matope asati akora.
Simba rinogona kukupa iwe matatu akasiyana echigarire mabhurogi plugs, anosanganisira soluble bhiriji plugs, composite bhiriji plugs uye cast iron bhiriji plugs, Vigor's zvachose bhiriji plugs akashandiswa munzvimbo huru oiri yemunda nzvimbo kumba nekune dzimwe nyika uye ave achizivikanwa zvakanyanya nevatengi. Pamusoro pezvo, Vigor's ichangoburwa recyclable bhiriji plug zvakare chimwe chezvinhu zvinonyanya kufarirwa zvigadzirwa, izvo zvinozivikanwa nekusimba kwayo kwemhando yekudzora uye kuita kwakanakisa, uye iri kuita imwe yesarudzo dzekutanga dzevatengi vakawanda 'kupedzisa michina. Kana iwe uchifarira iyo Vigor Completion Tool Bridge Plug Series kana zvimwe zvekuchera uye kupedzisa maturusi emafuta negasi indasitiri, ndapota usazeza kutibata nesu kune yakanakisa chigadzirwa rutsigiro uye tekinoroji rutsigiro.
