Umbhobho wentsimbi onomlinganiselo wangaphandle wokutyeba kodonga ungaphantsi kwama-20 ubizwa ngokuba ngumbhobho wentsimbi engqindilili.

Isetyenziswa ikakhulu njengemibhobho yokomba yepetroleum, imibhobho eqhekekileyo yoshishino lwepetrochemical, imibhobho yebhoyila, imibhobho ethwele imibhobho kunye nemibhobho echanekileyo yolwakhiwo oluphezulu yeemoto, iitrektara, kunye nenqwelomoya.

Inkqubo yokuvelisa umbhobho wentsimbi ongenamthungo

1. Ukuqengqeleka okushushu (umbhobho wentsimbi okhutshiweyo ongenamthungo): umbhobho wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → ukuqengqeleka okuqengqelekayo okuthathu, ukuqengqeleka okuqhubekayo okanye ukukhutshwa kombhobho → ukucolwa komlinganiselo (okanye ukunciphisa) → ukupholisa → Ukulungelelanisa → uvavanyo lwehydraulic (okanye ukubona isiphene) → ukuphawula → ugcino.

Izinto ezikrwada zokuqengqeleka kwemibhobho engenamthungo yibillet yombhobho ongqukuva, iibhilethi zemibhobho engqukuva zisikwa ngumatshini wokusika kwibillet enobude obumalunga nemitha eyi-1 kwaye ithunyelwe kwiziko lokufudumeza ngebhanti yokuhambisa. Ibillet ifakwa eziko kwaye ifudunyezwe kubushushu obumalunga ne-1200 degrees Celsius. Amafutha yihydrogen okanye iacetylene. Ulawulo lobushushu kwisithando somlilo ngumba ophambili. Emva kokuba ityhubhu ejikelezayo iphumile kwisithando somlilo, kufuneka ihlatywe ngomatshini woxinzelelo. Ngokubanzi, oyena matshini uqhelekileyo wokugqobhoza ngumatshini wokugqobhoza onetapered. Olu hlobo lomatshini wokubhoboza lunomgangatho ophezulu wokuvelisa, umgangatho omhle wemveliso, ukwandiswa kwedayamitha ye-perforation enkulu, kwaye unokugqoka iindidi zentsimbi. Emva kokubhoboza, i-tube billet ejikelezayo inqunyulwa ngokulandelelanayo, iqhubekile ngokuqhubekayo okanye ikhutshwe yimiqulu emithathu. Emva kokukhama, khupha ityhubhu kwaye ulinganise. Umatshini wokulinganisa ujikeleza ngesantya esiphezulu ngokusebenzisa i-conical drill bit ukubhoboza imingxuma kwintsimbi engenanto ukwenza umbhobho wentsimbi. Ububanzi obungaphakathi bombhobho wensimbi buchongwa ngobude bobubanzi bangaphandle be-drill bit yomatshini wokulinganisa. Emva kokuba umbhobho wensimbi ulinganisiwe, ungena kwinqaba yokupholisa kwaye upholiswe ngokutshiza amanzi. Emva kokuba umbhobho wensimbi upholile, uya kulungiswa. Emva kokulungiswa, umbhobho wensimbi uthunyelwa kwi-metal flaw detector (okanye uvavanyo lwe-hydraulic) ngebhanti yokuhambisa ukukhangela impazamo yangaphakathi. Ukuba kukho ukuqhekeka, ama-bubbles, njl. ngaphakathi kwipayipi yensimbi, iya kubonwa. Emva kokuhlolwa komgangatho wemibhobho yentsimbi, ukhetho olungqongqo lwencwadi luyafuneka. Emva kokuhlolwa komgangatho wombhobho wensimbi, penda inombolo ye-serial, inkcazo, inombolo yebhetshi yokuvelisa, njl. Ithwalwa ngekhreyini kwindawo yokugcina iimpahla.

2.Umbhobho wentsimbi obandayo (uqengqelekiyo) ongenamthungo: umbhobho wetyhubhu engqukuva → ukufudumeza → ukugqobhoza → isihloko → ukuqhola → ukuchola → ukufakwa kwe-oyile (icwecwe lobhedu) → umzobo obandayo ogqithisayo (ukuqengqeleka okubandayo) → ityhubhu yebillet → unyango lobushushu → ukolula → amanzi Uvavanyo loxinzelelo (ukubona iziphene) → phawula → ugcino.
