Packers Kutora Kufunga

1. Sunungura packer ine kushoma tubing manipulation, kudhonza zvakananga, kana 1/3 kutendeuka kuburitsa.

Nguva zhinji mamiriro ezvinhu zvakanaka kana zvimwe midziyo yekudonhedza pasi mutambo inoita kuti zvifarirwe kuita kuti mutakuri asunungurwe pasina kana tubing manipulation. Makomba akatsauka mienzaniso yekare, nepo kuvapo kwe eccentric gasi inosimudza parutivi pocket mandrels kana kureba kwe 1/4 ″ mutsara wekudzora mugomba ingave mienzaniso yeiyo yekupedzisira. Iyo yakatwasuka yekudhonza dhizaini ndiyo inonyanya kudiwa sarudzo mune dzakawanda zviitiko. Aya mapaketi anowanzo kuveura akapiniwa munzvimbo yakasetwa (kunze - mamwe marudzi etension set). Imwe sarudzo ndeye diki yekutenderera mhando kuburitswa (1/3 tendeuka pane paki) izvo zvimwe zvinodzoreredzwa vanazvo. Mazhinji chisimbiso akaboora mhando inodzoreredzwa inoburitswa nekukakavadzana kwakatwasuka asi chete mushure mekugadzira chisimbiso unit yadhonzwa. Aya mapaketi anoda imwe rwendo nechombo chekuburitsa kuitira kudhonza mutakuri. Nekudaro, hapana kutenderera kwetubing kunodiwa. Mashoma akakosha packers akagadzirwawo uye anomhanya ari akatwasuka kudhonza mushure mekunge sleeve yewaya yachinjwa. Iyi sarudzo inenge isingafarirwe nekuti kugona kudhonza packer kunoenderana newaya yekuwana kune iyo packer. Kushaikwa kwekuwana tubing kunogona kunge kuri chikonzero chekuda kudhonza paki yekugadzira pakutanga.

2. Back up kuburitsa kugona, kuchengetedza shear kuburitswa, kana kutenderera kusunungurwa.

Mamiriro ezvinhu asingadikanwi emutsime, asina kurongeka matambudziko ekugadzira, uye kusapindirana nemamwe maturusi ekudzika zvese zvikonzero zvinogona kuita kuti backup yekuburitsa kugona kuve chinhu chinodiwa. Kana iyo yekutanga yekuburitsa nzira isingagone kana kusashanda nekuda kwechimwe chikonzero, chimiro chakadaro chinova chakakosha. Dzimwe nguva, mikana iyi inogona kutarisirwa uye chimiro chakadaro chinofanirwa kuve nechekutanga mukusarudza kwepakiti. Rudzi rwakanyanya kuburitswa rwechipiri nderwekuveura shear pini kana screws zvine kudhonza kwakatwasuka. Nekudaro, kutenderera-rudzi rwechipiri kuburitswa kwakabatanidzwawo pane mamwe mapaketi.

3. Tubing kana packer inogona kudzoserwa neimwe yekuzadza, packer bypass kana flush seal unit.

Kumwe kuita kwekugadzira kunogona kuguma nekuzadza zvine mwero mucasing pamusoro pepakiti. Muenzaniso ungave kugadzirwa kwechikamu chechipiri pamusoro pechipeki chimwe chete mu tubing/casing annulus. Mafaindi anogadzirwa kubva kunzvimbo yekumusoro anogona kugara kunze kwepacker top. Mumamiriro ezvinhu akadaro, mutakuri anofanira kuiswa pedyo sezvinobvira kusvika pasi penzvimbo yepamusoro kana kuti sleeve inotsvedza inofanira kuiswa pedyo sezvinobvira kune packer top. Nekudaro, kunyangwe ipapo mamwe mafaindi acharamba aripo uye yekupfuura kana kudzvanya kuburitsa kunobatsira zvakanyanya kubvumidza iyo tubing kune casing kutenderera pamusoro pezvinhu kubvisa faindi kana marara. Muchigarire kana chisimbiso bore mhando inogona kudzoserwa, gungano rechisimbiso rinogona kupa kugona kwakafanana. Izvi zvinoshanda zvakanyanya kana musangano wechisimbiso wakaenzana kana diki muOD pane tubing.

4. Enzanisa kudzvanywa pakusunungurwa kwepacker, pressure unloader kana kupatsanura chisimbiso unit.

Kana ma packers achifambiswa kupfuura pakadzika pakadzika, zvinogoneka kana zvinogoneka kuti misiyano yakakura yekumanikidza inogona kuvepo pane iyo packer pakuburitswa. Kana mushandisi akasatakura tubing isati yaburitswa, iyo casing fluid pressure inogona kunge yakakwira zvakanyanya pane kudzvanywa kwemvura yakadzikira iri yoga. Musiyano kubva pazasi unogona kuvepo pasi pemamwe mamiriro kana dhairekitori riri roga rakachajwa nejekiseni kana kuti rakangodzvanyirirwa.

Chero zvazvingaitika, kana iyo yekumanikidza-yakaenzana mudziyo weimwe mhando isipo, saka pane mukana wakanaka wekuti kuburitswa kwepacker kungave kwakaoma, uye/kana iyo element package ichakuvadzwa mukuburitsa. Ichi chinhu chakakosha zvakanyanya kana iyo packer ichida kugadzikiswa parwendo rumwe chete. Sarudzo kune yemukati-kudzvanya-kuburutsa dhizaini dhizaini ndeyekuti kuenzana kwakafanana kunogona kuitwa nekudhonza chisimbiso musangano kunze kwechisimbiso bore mhando inodzoserwa packer.

5. Sunungura mutakuri usina tubing rwendo, tubing inobatanidza zvakananga kune packer.

Sezvambotaurwa, vamwe vanotakura vanoda kutenderera-rwendo rwetubhing kuitira kuti vatore gungano rechisimbiso uye kumhanyisazve chishandiso chekudhonza. Izvi hazvibvumirwi mune zvimwe zviitiko. Mune mamwe maoparesheni akaiswa apo kushanda kwese kwakajairika, hupfumi hwemaitiro akadaro ekudhonza haagone kupembedzwa. Kuti ukwanise kudhonza mutakuri usingaite tubing rwendo, inofanirwa kunge iri yerudzi rwakagadzirirwa kusungirirwa zvakananga kune tubing uye kwete chisimbiso bore mhando inodzoserwa iyo inosungirirwa kune tubing kuburikidza nelatch pane chisimbiso musangano. . Kunze kweiyo wireline yekuburitsa vhezheni yakambokurukurwa. Mazhinji emhando idzi dzeshinda-ku-packer dzinogona kugadziridzwa nemidziyo kuitira kuti tubing idhonzwe zvakasiyana kubva kune inotakura uye ichiramba ichidzoreredza pasina tubing rwendo rwekudzoka.

6. Chigayo chiri nyore, chigayo chinhambwe, uye chisingatenderere.

Zvinodiwa nyore uye nekukurumidza millable zvachose packer zviri pachena. Packer madhizaini anoita kuti izvi zvikwanisike anosanganisira simbi inogayiwa, madhizaini ezvinhambwe zvishoma zveguyo, magadzirirwo ezvishoma maOD's milled, uye anti-kutenderera kukiya maficha.

Vigor's packer series zvigadzirwa zvinogadzirwa zvinoenderana neakakwira zviyero zve API 11D1, uye ese anotakura kubva kuR&D kusvika pakugadzirwa kusvika kwekupedzisira kuendesa kune vatengi anodzorwa uye akanyorwa kuti ave nechokwadi chekuti mhando yezvigadzirwa inogona kusangana nezvinodiwa nevatengi. Kana iwe uchifarira huwandu hweVigor hwepfuti dzinopisa, ndapota usazeza kubata neboka rehunyanzvi reVigor kuti uwane rutsigiro rwechigadzirwa chepamusoro uye rutsigiro rwehunyanzvi.
