Izinhlobo ze-Perforation Systems
Izindlela ezintathu zokubhoboza ezisetshenziswa embonini kawoyela negesi izibhamu zokuqopha, izibhamu ezidluliswa ngamashubhu kanye nezibhamu zamashubhu.
I-Casing Gun System (I-Wireline Convey)
I-casing gun system iyindlela endala yokubhoboza futhi ihilela ukubhoboza ukuze kubhoboze umthombo ngaphambi kokuphothula. Izimo ze-Wellbore zingaba zilinganisela ngokweqile noma zingalingani kahle lapho zimboza. Ukwengeza, umthombo kufanele uncishiswe ngaphambi kokuqaliswa kokuqedwa ngoba uzonciphisa ukulimala kokwakheka.
Ezinye izinzuzo ze-casing gun zibalwe ngezansi;
Izibhamu zokubhoboza zingase zisetshenziswe ngocingo noma ngolayini kagesi ukuze uthole ukulawula ukujula okunembile
Kungasetshenziswa izibhamu ezinobubanzi obukhulu.
Ukulawula kahle kahle
Ukusebenza kulula ngomshini futhi kuthembekile
Okunye okungalungile kwesibhamu se-casing kubalwe ngezansi;
Kuthatha isikhathi esiqondile sokubhoboza
Idinga imishini yokulungisa phansi
I-Tubing Conveyed Perforation System (TCP)
Kulesi simiso, isibhamu se-perforation sinamathiselwe futhi siqhutshwa ngentambo yokuqedela. Lolu hlelo ludinga ukumba imbobo eyengeziwe ebizwa ngokuthi “sump” ukuze kufakwe isibhamu esinezimbobo esizolahlwa futhi sishiywe emthonjeni ngemva kokudubula isibhamu.
Ezinye izinzuzo zenqubo yokudlulisa amashubhu zibalwe ngezansi;
Isikhathi eside se-reservoir singabhobozwa ngokugijima okukodwa
Amanani okuqhuma amakhulu kunesistimu yamashubhu
Ukubhoboza kungenziwa ngaphansi kwesimo esingalingani kahle ukuze kuncishiswe ukulimala kokwakheka.
Ukwehliswa okukhulu kwesikhathi sokusebenza
Ububi bendlela yokudlulisa amashubhu kubalwe ngezansi;
Kuthatha isikhathi eside ngaphambi kokuthi kuxoshwe amacala okubhoboza
Nge-Tubing System
Ngokubhoboza amashubhu kuvumela ukubhoboza ukuba kwenziwe ngentambo yokuqedela ekhona. Lolu hlelo lunemikhawulo kusayizi weshaja kanye nesibhamu sokubhoboza ngoba izibhamu kufanele zibe zincane ngokwanele ukuze zingene ochungechungeni lokuphothula. Imvamisa, ubukhulu besibhamu buncane kuno-2-1/8.”
Izinzuzo ngohlelo lwamashubhu zimi kanje;
Gcoba umthombo ngentambo yokuqedela
Ukuthunyelwa okusheshayo nokubuyisa ngokusebenzisa izintambo zocingo noma amayunithi kalayini kagesi
Yehlisa ukulahleka kokukhiqiza
Ukulawula ukujula okunembile
Izindleko ezincishisiwe ngoba akukho ukubuyiswa kokuqedwa okudingekayo
Okubi ngohlelo lwamashubhu kanje;
Ububanzi obuncane bezindleko zokubhoboza bungasetshenziswa uma kuqhathaniswa nolunye uhlelo lokubhoboza. Ngakho-ke, ukujula kokungena akujulile kunezinye.
Ubude be-perforation ekugijimeni okukodwa bukhawulelwe izinto zokusebenza ezingaphezulu.
