Isibhamu esibhobozayo iyisisetshenziswa esisetshenziselwa ukubhoboza noma ukubhoboza izimbobo emithonjeni kawoyela negesi ngenhloso yokukhiqiza. Izibhamu ezibhobozayo zihlanganisa iziqhumane ezimise okwezimo eziningi futhi ziklanywe ngohlu lokucushwa nosayizi. Isici esibalulekile sesibhamu ububanzi. Usayizi ngokuvamile unqunywa ukwenzeka kwemikhawulo ye-wellbore noma imikhawulo ekhokhiswa impahla yangaphezulu.
Lezi zibhamu zithola ukusetshenziswa kanye nokusetshenziswa kuzo zonke izimboni ezihlukahlukene kodwa ukusetshenziswa okuvame kakhulu izimboni zemithombo kawoyela negesi. Izinhlobo eziningi zezibhamu ezibhobozayo ziyatholakala futhi ukusetshenziswa kuncike kuhlelo lokusebenza. Embonini yokumba, kudingeka ukuthi bavule ama-casings. Aqukethe amashaji amaningi amise okweziqhumane adala uhlobo lwezimbobo ezidingekayo ekuvuleni amasayizi ahlukene nezinhlobo zamakesi. Embonini yokumba, izibhamu zokubhoboza ziyingxenye yamathuluzi avamile asetshenziselwa ukuxhuma amapayipi.
Zisetshenziswa kanjani ensimini?
Uma kukhulunywa ngokumba emithonjeni kawoyela yendabuko, inqwaba yamakesi omkhiqizo anezindonga eziwugqinsi ayafakwa futhi afakwe usimende endaweni yawo. Lokhu kuvaleka okuqinile kuyadingeka ukuze kungabikho uketshezi olulele echibini olungafinyelela emthonjeni. Uma isikhathi sesilungile sokuqala ukukhiqiza, izimbobo kufanele zenziwe ngebhokisi kanye nosimende. Kudingeka zijule futhi zibe ziningi ngakho-ke ukusetshenziswa kwe-drill bit evamile ngeke kwanele. Lokhu kwenza ukuthi kuphoqeleke ukuthi kusetshenziswe izibhamu ezibhobozayo. Bakhulisa lezi zimbobo ngokufaka iziqhumane ezimise okwezimo.
Izinhlobo zezibhamu zokubhoboza
Kunezinhlobo ezintathu ngokuyinhloko zezibhamu ezibhobozayo futhi ukusetshenziswa kwazo kusekelwe lapho zidingeka khona:
Isibhamu esingenalutho esingabuyiswa
· Kulesi sibhamu, ishubhu lensimbi livikela ukushaja futhi lesi sibhamu ngokuvamile sishiya udoti omncane ngemuva.
Isibhamu esisebenzisekayo
· Lezi zibhamu ezibhobozayo zisebenzisa amacala ngamanye. Amacala avaliwe futhi abambe icala. Lezi zibhamu zishiya ngemuva inqwaba yemfucumfucu emthonjeni.
Isibhamu esibiza kancane
· Amashaji kulezi zibhamu alandwa ngokusebenzisa izithwali zezintambo. Ngezinye izikhathi, izinsimbi zensimbi zingasetshenziswa. Lezi zibhamu zikhipha ubuningi bemfucumfucu obushiywe eziqhumeni. Inzuzo yezibhamu ezinjalo ukuqina kwazo nokusetshenziswa kabusha.
Izibhamu zokubhoboza zitholakala ngobukhulu obuhlukahlukene futhi ukusetshenziswa kwazo kuyahlukahluka. Amabhizinisi e-petroleum kufanele agcine ama-overheads aphansi emkhakheni futhi avikele izimpahla ezibalulekile. Ukuphila nokusebenza kahle kwezibhamu kuwumsebenzi wokuvikela izingxenye zentambo ezibhamuni. Amabhizinisi amaningi asebenzisa izivikeli zentambo yangokwezifiso ukusiza izingxenye ukuthi zihlale zomile futhi ngaleyo ndlela ziqinisekise ukushaja okungaguquki.
