Amaphakethe angamathuluzi okukhipha amanzi asetshenziswa ekungeneleleni okuhlukahlukene kanye nemisebenzi yokukhiqiza ukudala ukuhlukaniswa phakathi kweshubhu ne-casing.
Lawa madivayisi anobubanzi obuncane lapho eqhutshwa embobeni kodwa kamuva lapho ukujula okuqondiwe kufinyelelwa kuwo ayanwebeka futhi asunduze ku-casing ukuze anikeze ukuhlukaniswa.
Amapaki okukhiqiza asetshenziselwa ukuvikela amashubhu okukhiqiza emthonjeni kanye nokuhlinzeka ngokuhlukaniswa kwe-tubing/casing annulus ngemva kokuba umthombo usubhodliwe futhi uvuselelwe.
Ngokuvimbela uketshezi lomthombo ukuthi lungathintani nebhokisi futhi lubangele ukugqwala, ukuphila kwawo kunganwetshwa.
Ngokuvamile kulula kakhulu ukushintsha amashubhu okukhiqiza kunokulungisa i-casing eyonakele.
Amaphakethe nawo avame ukusetshenziselwa imisebenzi ehlukahlukene yokuphothula kahle njengokuqhekeka, ukwenza i-asidi, noma ukufaka usimende.
Kulezi zinhlelo zokusebenza, umpakishi uvamise ukugijima embobeni njengengxenye yokuhlanganisa imbobo engezansi.
Ngemva kokuba umsebenzi usuqediwe (ngokwesibonelo indawo iphukile) umpakishi akasethiwe futhi ithuluzi lingahanjiswa liye endaweni elandelayo.
Yiziphi Izingxenye Eziyinhloko Ze-Packer?
UMandrel - umzimba wompakishi
Iziliphu - ezisetshenziselwa ukubamba ububanzi bangaphakathi (ID) bebhokisi futhi kuvimbele umpakishi ukuthi anganyakazi.
I-Packing-element - ngokuvamile into yerabha ehlinzeka ngokuhlukaniswa. Le elementi iyakhula lapho umpakishi efinyelela ekujuleni okufunayo futhi esethiwe.
Ikhoni - isici esiphusha kuma-slip lapho kusetshenziswa amandla angaphandle.
Indandatho yokukhiya - ivimbela umpakishi ukuthi angahlethi lapho kukhishwa amandla angaphandle.
Izinhlobo Packers
Amapaki ahlukaniswe abe yizinhlobo ezimbili eziyinhloko: unomphela futhi angabuyiselwa.
Amapaki ahlala njalo asetshenziswa emisebenzini engadingi ukususwa kompakishi ngokushesha.
Ahlinzeka ngokuvala okungcono kunamapaki abuyiselekayo futhi ngokuvamile ashibhile.
Uma kudingekile, amapaki ahlala unomphela angasuswa ngokugaya ngamashubhu ahlanganisiwe.
Ngokuvamile, emithonjeni yokushisa ephezulu kanye ne-high-pressure, ama-packers ahlala njalo akhethwa.
Amaphakethe abuyiselekayo angasuswa kalula futhi asetshenziswe kabusha ngokusebenzisa amandla angaphandle kuwo.
Zivame ukusetshenziselwa imisebenzi yokungenelela kahle lapho izindawo ezithile kufanele zihlukaniswe izikhathi eziningi phakathi nokusebenza.
