Iindlela zokuSeta iPacker

I-Weight-Seti okanye i-Compression Set Packers

Olu hlobo lokupakisha lunokusekwa ngokuzimeleyo okanye lunokuthi luqhutywe njengenxalenye ebalulekileyo yomtya we-tubing kwaye ibekwe xa umtya uhla.

Ngokwesiqhelo abapakishi bobunzima boseti basebenzisa isiliphu kunye nendibano yekhowuni enokuthi isebenze ukubonelela ngoxinzelelo lwento yokutywina, nje ukuba imithombo yokutsala okanye iibhloko zokukhuhlana zinokubandakanya udonga lwangaphakathi lwecasing. Iindlela zokukhulula iziliphu zidla ngokufunyanwa kusetyenziswa isixhobo se-J slot esithi xa sisebenza sivumele ubunzima bomtya ukuba buthotywe kwaye ngaloo ndlela bucinezele into yokutywina. Ukukhutshwa kwento kunokufumaneka ngokuthatha ubunzima bomtya.

Olu hlobo lwenkqubo yokumisela i-packer luya kulungeleka kuphela ukuba ubunzima bungasetyenziswa kwi-packer enokuthi ingabikho kwimigodi ethambekele kakhulu. Ukongeza, umpakishi uya kukhulula ukuba kukho umahluko woxinzelelo oluphezulu ukusuka ngaphantsi kompakishi.

Abapakisheli be-compression-set packers ngokubanzi bafuna i-8,000 ukuya kwi-14,000 yeponti ubuncinane bemikhosi yokumisela kwizinto (i-packer element durometer kunye nobushushu kubunzulu bokusetha kufuneka kuqwalaselwe). Oku kunokuba yingxaki ngaphantsi kweenyawo ze-2,000 ukususela ekubeni ubunzima obufunekayo bombhobho wokubhobhoza buthandabuza ngokuxhomekeke kubungakanani bompakishi kunye nobukhulu betyhubhu / ubunzima ngeenyawo.

IiPaki zoSeto lweTension P

Olu hlobo lompaki ngokufanelekileyo luseti yobunzima bokupakisha bujonge ezantsi, oko kukuthi, isiliphu kunye nenkqubo yekhowuni ibekwe ngaphezulu kwendawo yokutywina. Ziluncedo ngakumbi kwizicelo apho uxinzelelo lomngxuma osezantsi osezantsi kwaye ke ngoko kukho uxinzelelo olwahlukileyo olusuka ngaphantsi kompakishi. Le meko iyenzeka kwimibhobho yokutofa kwamanzi, apho uxinzelelo lwe-injection luya kunceda ekugcineni ukumiswa kwepakethe. Ukunyamekela kufuneka kuthathwe ukuqinisekisa ukuba naluphi na ukunyuka kweqondo lokushisa kwintambo kunye nokwandiswa kwentambo ngenxa yoko akuyi kubonelela ngamandla okwazi ukukhupha ipakethe.

Olona khetho luqhelekileyo lokugqibezela iseti enganzulwanga ngumatshini- tension-set packer. Oku mhlawumbi kungenxa yokuba iqula elingekho nzulu ngokubanzi libonisa iimeko zoqoqosho ezingabalulekanga kwaye oomatshini abaseti yoxinzelelo bathande ukuba nexabiso eliphantsi kuneseti yehydraulic okanye iseti yocingo enokubuyiswa.

Roto-Mechanical Seti Packers

Kulo hlobo lokupakisha, inkqubo yokumisela i-packer iqhutywe ngokujikeleza kwe-tubing. Ukujikeleza komtya nokuba

inyanzelisa iicones ukuba zityibilike emva kwesiliphu kwaye ngaloo ndlela zicinezele itywina, okanye ikhuphe i-mandrel yangaphakathi ukuze ubunzima betyhubhu busebenze kwiicones ukucinezela into yokutywina.

Hydraulic-Seti Packers

Kolu hlobo lokupakisha, inkqubo yokuseta ixhomekeke kuxinzelelo lwehydraulic oluveliswe ngaphakathi komtya osetyenziselwa nokuba:

●qhuba ipiston ukwenza intshukumo yesiliphu kunye nenkqubo yekhowuni ngokwenza oko iqulathe into yokutywina, okanye ngenye indlela.

●vula iseti yeziliphu eziphezulu kwipakethe eya kuthi emva koko ilungise indawo yokupakisha kwaye ivumele ukutsalwa koxinzelelo kwi-packer kwaye icinezele inkqubo yokutywina.

Kulungiselelo lwangaphambili, xa i-piston eqhutywa nge-hydraulically isebenze intshukumo yekhowuni, intshukumo yokubuya kwekhowuni kufuneka ithintelwe ngesixhobo sokutshixa ngoomatshini.

Ukuvumela uxinzelelo lwe-hydraulic ukuba lwenziwe kwi-tubing ngaphambi kokumiselwa kompakishi, iinkqubo ezi-3 eziphambili ziyafumaneka zokuplaga i-tubing:

●Ufakelo lweplagi engenanto efana neplagi ye-Baker BFC ngaphakathi kwingono efanelekileyo njengengono ehlala i-Baker BFC.

●Ukusetyenziswa kwesitulo esinokuchithwa apho ibhola inokuwiswa phantsi komtya wetyhubhu. Emva kokusebenzisa uxinzelelo olugqithisileyo emva kokuseta ipaki, ibhola kunye nesihlalo zichebe kwaye iwele kwi-sump yequla. Olunye uyilo lubonisa ikholethi eyandiswayo eya kuthi ihle kwaye inyuke iye kwikhefu nje ukuba ichebe izikhonkwane, ngaloo ndlela ivumela ibhola ukuba idlule.

●Ukusetyenziswa kwe-sub differential displacing sub, ivumela ulwelo lwetyhubhu ukuba lususwe kwiindawo ngezibuko kwi-sub phambi kokuseta ipakeli. Ibhola xa iwisiwe iya kuhlala kwikholethi eyandisiweyo eya kuvumela uxinzelelo ukuba lwenziwe. Nje ukuba i-overpressure isetyenziswe, ikholethi ihlehlela ezantsi kwaye ngokwenza njalo, ivale ivalve yokujikeleza kwaye ivumele ibhola ukuba iwele.

IiPackers zokuSeta iintambo zoMbane

Kule nkqubo, ikhithi ye-adapter ekhethekileyo ixhunyiwe kwi-packer, kunye okanye ngaphandle kwe-tailpipe, kwaye inkqubo iqhutyelwa equleni kwi-wireline kunye nesixhobo sokulungelelanisa ubunzulu njenge-collar locator ye-CCL Kwi-deep deep, i-electric Umqondiso ogqithiselwe phantsi intambo ivuthela intlawulo evuthayo evuthayo ehlala kwisixhobo sokubeka ngokuthe ngcembe esakha uxinzelelo lwegesi kwaye isebenze intshukumo yepiston ukucinezela inkqubo yetywina.

Olu hlobo lwesixokelelwano lukhokelela kwinkcazo yobunzulu obuchanekileyo bommiselo wompakishi kunye nenkqubo yolungiselelo olukhawulezayo/lofakelo. Ukungalungi kubunzima bokuqhuba i-wireline kwimithombo ephezulu-engileyo kunye nenyaniso yokuba umpakishi kufuneka abekwe ngokwahlukileyo ukusuka ekufakweni okulandelayo kwe-tubing.
