UHlelo lokuGqibezela abaPaki: Iyafumaneka kwaye iSisigxina

Abapakisheli ababuyiswayo bayinxalenye ebalulekileyo yetyhubhu, eqinisekisa ukuba ityhubhu ayinakutsalwa ngaphandle kokutsala isipakishi, ngaphandle kwamatyala abandakanya iplagi yebhulorho efumanekayo. Aba paki basenokusetwa ngoomatshini, ngokwe-hydraulically, okanye ngokudityaniswa kweendlela zombini. Ngokuqhelekileyo zisetyenziswa kwiimeko apho iqula lifuna abantu abasebenzayo rhoqo, njengakusetyenziso lwempompo engaphantsi kwamanzi, ukugqityezelwa okwexeshana njengovavanyo lwemveliso, okanye imisebenzi yongenelelo eyahlukahlukeneyo efana nokuvuselela okanye ukufunyaniswa kokuvuza.

Iingqwalasela xa uqhuba iiPaki eziFumanayo:

1.Ukuswabha iqula: Ukutsalwa kompakishi ngaphandle kwequla kunokukhokelela ekuphangeni, ekufuneka kulawulwe ngononophelo.

I-2.I-Pressure Equalization: Ukufezekisa ukulingana koxinzelelo kwi-packer ngaphambi kokuyikhupha kunokuba ngumngeni, ngakumbi kwiimeko ezisezantsi ngexesha lemisebenzi yokungazinzi.

3. Ukucheba kwangaphambi kwexesha: Iipaki zokukhulula ezitsalwa ngokuthe ngqo zinokucheba kwangethuba kwaye zikhulule ngenxa yokufinyela kwetyhubhu.

I-4.Iidiphozithi: Iidiphozithi ezingaphezulu kompakishi zingenza ukuba zingabuyiswa, zifuna isilumkiso ngexesha lokusebenza.

Abapakishi besigxina babekwe ngaphakathi kwe-casing, kwaye indlela yabo yokumisela (ingaba i-tubing okanye i-wireline) inokukhutshwa kwi-packer. Ngaphandle kweplagi yebhulorho esisigxina, i-tubing inokuqhutywa kwaye iphinde ifakwe kwi-packer. Aba paki basenokusetwa ngoomatshini (usebenzisa iityhubhu), ngokwehydraulically, okanye ngombane (ngocingo). Njengoko igama libonisa, azinakufunyanwa kwakhona kodwa zinokususwa ngokutshabalalisayo, ngokuqhelekileyo ngokusila. Abapakishi besigxina badla ngokuqeshwa kwizicelo zoxinzelelo oluphezulu.

IiPaki ezisisigxina / ezibuyiselwayo: Olu didi lwepakethi ludibanisa iingenelo zabapakishi besigxina, ezifana nebhobho enkulu kunye nokukwazi ukumelana nokwahluka koxinzelelo oluphezulu, kunye nokuguquguquka okongeziweyo kokukhululwa kunye nokubuyiswa ngokufanelekileyo kwiqula xa kuyimfuneko.

Iinqobo zokuKhetha zabaPaki abaSisigxina: Umpakishi osisigxina udla ngokukhethwa ukuba:

I-1.Uxinzelelo oluqikelelweyo olwahlukileyo oluqikelelweyo kwi-packer ludlula i-5000 psi.

2.Iqondo lobushushu kubunzulu bokusetha budlula i-225°F.

I-3.H2S ikhona, kwaye iqondo lobushushu kwi-packer lingaphantsi kwe-160 ° F.

4.Kulindeleke ukuba usebenze rhoqo.

Ukukhethwa kwe-packer kufuneka kusekelwe kwimeko yangempela yendawo yakho, i-Vigor ibandakanyeka kakhulu kwi-oyile kunye ne-gas industry kwaye inamava anzulu kwintsimi kule ndawo, ukuba unomdla kumapaki ethu okanye ezinye izixhobo zokugaya kunye nokugqiba, nceda. ungalibazisi ukuqhagamshelana nathi ukuze ufumane inkxaso yobuchwephesha.
