1.Ishubhuukuhlukaniswa

Ishubhu ingahlukaniswa ibe yishubhu (NU), ishubhu ephazamisekile (EU) kanye neshubhu elihlangene jikelele.I-flat isho ukuphela kwepayipi lesikhwama sikawoyela ngaphandle kokuxhuma ngokuqondile futhi ilethe ama-coupling.Amashubhu acasukile asho ukuthi amapayipi amabili aphelile ngenxa yokucasuka kwangaphandle, bese exhuma futhi alethe ama-coupling.Sekukonke amashubhu ahlanganyelwe asho ngomucu wemoto ophazamisekile wangaphakathi kwelinye icala ngemoto ngaphandle kwentambo ewugqinsi, ngaphandle kokuxhumana okuqondile.

2.Iqhaza le-Tubing

① ukukhipha uwoyela negesi: uwoyela negesi ukukhahlela kosimende bese kufakwa epayipini lebhokisi likawoyela ukuze kukhishwe uwoyela negesi phezulu.

② amanzi: Uma ingcindezi ye-downhole inganele, ngokusebenzisa ishubhu emanzini omthombo.

③ umjovo umusi: in uwoyela esindayo inqubo ezishisayo alulame, ukusetshenziswa amashubhu intuba downhole okokufaka umusi.

④ Ukufakwa kwe-asidi nokuqhekeka: Sekwephuzile ekubhojweni kwemithombo kawoyela negesi noma ukuze kuthuthukiswe isivuno, kuyadingeka ukuthi kufakwe i-acidification ye-reservoir kanye ne-fracturing media noma yelashwe, futhi okuphulukisiwe kulethwa ngepayipi.
