Ukongeza ekusetyenzisweni kwe-oyile, ukuvela kwe-oyile ye-oyile kunokusetyenziswa njengombhobho wokuthutha izinto ezikrwada. Ukuphucula umgangatho we-oyile ye-oyile, ikhonkco ngalinye kwinkqubo yokuvelisa ibaluleke kakhulu, ngakumbi ulawulo lobushushu ngexesha, ekufuneka lilandelwe ngokungqongqo. Ubuchule bemigaqo. Ngokuqhelekileyo, i-petroleum casing ithatha indlela yokucima ubushushu obuphantsi endaweni yendlela eqhelekileyo yokucima, kuba indlela eqhelekileyo yokucima iya kushiya inani elikhulu loxinzelelo olushiyekileyo ngaphakathi kwendawo yokusebenza, ngaloo ndlela yandisa ubuqhophololo kunye nokwenza ukuba inkqubo elandelayo ingabi lula. Ukucima okuphantsi kobushushu kukuthintela ukunyanzeliswa okugqithisileyo kwe-oyile ye-oyile ekuchaphazeleni inkqubo elandelayo. Eyona ndlela iphambili yokusebenza kukukhetha kuqala ubushushu bobushushu bokucima ubushushu obuphantsi, ngokuqhelekileyo phakathi kwe-740-810 ° C, kwaye ixesha lokufudumeza ngokubanzi malunga nemizuzu eyi-15. Emva kokucima, ukuthambisa kwenziwa. Ixesha lokufudumeza lobushushu yimizuzu engamashumi amahlanu, kwaye iqondo lobushushu kufuneka libe yi-630°C. Ngokuqinisekileyo, uhlobo ngalunye lwentsimbi lunobushushu balo kunye nexesha ngexesha lonyango lobushushu. Ngethuba nje inokuphucula ukusebenza kwe-workpiece, ngoko unyango lokushisa Injongo ifezekisiwe.

Unyango lobushushu yeyona nkqubo ibalulekileyo ekusetyenzweni kwe-petroleum casing. Ingaba ukusebenza kunye nomgangatho wemveliso egqityiweyo inokuhlangabezana nemigangatho ubukhulu becala kuxhomekeke kwiziphumo zonyango lokushisa. Ke ngoko, umenzi ngamnye uneemfuno ezingqongqo kakhulu zenkqubo yonyango lobushushu kwaye ungalibali ukuyihoya. Ngamanye amaxesha ukucinywa kobushushu obuphantsi kungasetyenziselwa ukucima. Ukucima ubushushu obuphantsi kunokususa ngokufanelekileyo uxinzelelo olushiyekileyo lwe-oyile. Ayinciphisi nje kuphela iqondo lokuguqulwa kwesixhobo sokusebenza emva kokucinywa, kodwa iphinda iqhubele phambili i-oyile ye-oyile ibe yimathiriyeli ekrwada ifaneleke ngakumbi kwiinkqubo zamva. Ngoko ke, impumelelo yangoku ye-oyile ye-oyile ayinakwahlulwa kunyango lobushushu. Ekubeni inkqubo yonyango lobushushu iye yaziswa, nokuba yimpembelelo yokuqina, ukusebenza okuchasene nokutshatyalaliswa, okanye amandla okuqina kwe-oil casing, kuye kwakho ukuphuculwa okukhulu. ukuphucula.
