Ikhanda Lokushuba: Imishini Ethembekile Yekhanda Lomthombo Wokukhiqiza Uwoyela Negesi

Ikhanda lepayipi lenza imisebenzi emithathu eyinhloko: ukulengisa intambo yepayipi emgodini; ukuvala i-annulus phakathi kwepayipi kanye nebhokisi; kanye nokunikeza ukuguquka kwekhanda lebhokisi elingezansi kanye nesihlahla sikaKhisimusi ngaphezulu. Amachweba amabili aseceleni emzimbeni wekhanda lepayipi anezindlela ezine enza imisebenzi efana nokujova ipayipi kanye nokuwasha imigodi.

I-tubing hanger, ingxenye ebalulekile yekhanda le-tubing, yenzelwe ukusekela intambo ye-tubing nokuvala isikhala esiphakathi kwe-tubing kanye ne-casing. Isebenzisa isakhiwo sokuvala amandla adonsela phansi, lapho i-tubing hanger ibekwe khona ekhoneni le-spool yekhanda le-tubing kusetshenziswa isisindo sentambo ye-tubing, ukuqinisekisa ukuvalwa okuthembekile, ukusebenza okulula, ukuxhumana okusheshayo kwekhanda le-wellhead kanye nokuphepha okuphezulu. Lo mklamo usetshenziswa kabanzi emithonjeni ejulile ephakathi kanye nasemigodini evamile.

Sinikeza uhla oluphelele lwezixazululo zekhanda lepayipi, kufaka phakathi ikhanda lepayipi elilodwa, ikhanda lepayipi eliphindwe kabili, kanye nekhebula ngqo ngekhanda lepayipi, kanye nama-hangers ahambisanayo (i-hanger eyodwa, i-hanger yepayipi eliphindwe kabili, enekhebula elidlula i-hanger), ukuze kuhlangatshezwane nezimo ezahlukahlukene zemithombo efana nemithombo evamile, imithombo yezintambo eziningi kanye nemithombo edinga ukungena kwekhebula. Yakhiwe ngezinto ezisezingeni eliphezulu kanye nobuchwepheshe bokucubungula obuthuthukisiwe, amakhanda ethu epayipi anikeza ukusebenza okuzinzile, ukuvalwa okuthembekile kanye nokuphila isikhathi eside kwenkonzo, okusekela imisebenzi yokukhiqizwa kukawoyela negesi ephephile nephumelelayo.
