Ukuqonda I-Drilling Fluid
Uketshezi lokumba, okwaziwa nangokuthi udaka lokumba, lusebenza njengento esebenzayo eminingi ebalulekile ekusebenzeni kokumba ezimbonini ezahlukahlukene, ezihlanganisa uwoyela negesi, i-geothermal, nezimayini.Inhloso yawo eyinhloko ukusiza ekubhojweni kwemigodi, ukugcina ukuzinza kwe-wellbore, ukupholisa kanye nokugcoba i-drill bit, ukuhambisa izinsimbi zokubhoboza phezulu, nokuvimbela ukulimala kokwakheka.Uketshezi lokumba luyingxube eyinkimbinkimbi ehlanganisa izingxenye ezihlukahlukene eziklanyelwe ukuhlangabezana nezidingo ezithile zokumba.
Izingxenye Ze-Drilling Fluid:
I-Base Fluid: Uketshezi oluyisisekelo lwakha isisekelo soketshezi lokumba futhi lungaba ngamanzi, uwoyela, noma ukwakheka okwenziwe, kuye ngezimo zokumba nemithetho yemvelo.Uketshezi olusekelwe emanzini luvame ukusetshenziswa ngenxa yezindleko zabo kanye nobungane bemvelo.
Izengezo: Izithasiselo zifakwa oketshezini lokumba ukuze kuthuthukiswe ukusebenza kwalo futhi kubhekwane nezinselele ezithile okuhlangatshezwane nazo ngesikhathi sokumba.Lezi zengezo zihlanganisa ama-viscosifiers, ama-ejenti okulawula ukuhlunga, okothambisa, ama-shale inhibitors, ama-weighting agents, nama-ejenti okulawula ukulahlekelwa uketshezi.
Izinto Zokukala: Izinto zokukala, ezifana ne-barite noma i-hematite, zengezwa ukuze kwandiswe ukuminyana koketshezi lokumba, okulwenza lube nengcindezi eyanele yokubhekana nezingcindezi zokwakheka ezihlangatshezwana nazo ekujuleni.
I-Rheology Modifiers: I-Rheology modifiers ilawula ukugeleza koketshezi lokumba, iqinisekisa ukumiswa okwanele kokusikwa kokubhoboza kanye nokuthuthwa okuphumelelayo kuya phezulu.Iziguquli ezivamile ze-rheology zihlanganisa i-bentonite, ama-polymers, ne-xanthan gum.
Ama-Corrosion Inhibitors: Ama-Corrosion inhibitors ahlanganiswe ukuze avikele izinto zokusebenza zokumba kanye nezingxenye ze-downhole ezintweni ezigqwalayo ezikhona kuketshezi olwenziwayo.
Ama-Biocides: Ama-biocides avimbela ukukhula kwamagciwane nama-microorganisms ngaphakathi koketshezi lokumba, anciphise ubungozi bokugqwala okubangelwa yi-microbiologically induced (MIC) nokugcina uketshezi oluzinzile.
Ukwehlukanisa Udaka Lokubhoboza Kuketshezi Lokubhoboza
Nakuba udaka lokumba kanye noketshezi lokumba kuvame ukusetshenziswa ngokushintshana, abanye ochwepheshe benza umehluko phakathi kwala magama womabili ngokusekelwe ezimpahleni nasekusetshenzisweni kwawo.
Ukubhoboza Udaka: Ngokwesiko, udaka lokumba lubhekise ngqo oketshezini lokumba olususelwa kuwoyela.Udaka lokumba ngokuvamile luqukethe uketshezi oluyisisekelo olwakhiwe imikhiqizo ye-petroleum ecolisisiwe noma amafutha okwenziwa.Udaka olusekelwe kuwoyela lunikeza izinzuzo ezifana nokugcotshwa okuthuthukisiwe, ukuzinza okuphezulu kwezinga lokushisa, kanye nokuzinza kwe-wellbore okuthuthukisiwe ekwakhiweni okuthile.
Uketshezi Lokubhoboza: Ngokuphambene, uketshezi lokumba luhlanganisa isigaba esibanzi esihlanganisa kokubili ukwakheka okususelwe emanzini nokusekwe kuwoyela, kanye noketshezi olusekelwe ekwenziweni.Uketshezi lokumba olusekelwe emanzini, oluhlanganisa iningi lemisebenzi yokumba, luvame ukubizwa ngokuthi uketshezi lokumba.Uketshezi olusekelwe emanzini luyathandwa ezimweni eziningi zokumba ngenxa yokuhambisana kwemvelo, izindleko eziphansi, kanye nokuchithwa kalula.
Izicelo Nezinselele
Izicelo:
Ukumba Kokuhlola: Uketshezi lokumba ludlala indima ebalulekile emisebenzini yokumba yokuhlola, lapho inhloso eyinhloko kuwukuhlola i-geology engaphansi komhlaba nokuhlonza amadamu e-hydrocarbon angaba khona.
Ukwakhiwa Kwemithombo: Ngesikhathi sokwakhiwa komthombo, uketshezi lokumba lusiza ekusimamiseni umthombo, ukulawula izingcindezi zokwakheka, kanye nokwenza lula ukufakwa kwegobolondo nosimende.
Ukuhlolwa Kokwakheka: Uketshezi lokumba luvumela ukutholwa kwamasampula ayisisekelo angaguquki futhi lusize amasu ahlukahlukene okuhlola ukwakheka, okuhlanganisa ukugawulwa kwemithi nokuhlola.
Izinselelo:
Ukukhathazeka Ngemvelo: Ukulahlwa koketshezi olumbayo kubangela izinselelo zemvelo, ikakhulukazi emisebenzini yokumba ogwini lapho imithetho eqinile ibusa ukuchithwa kwamanzi ezindaweni zasolwandle.
Ukonakala Kokwakheka: Uketshezi lokumba olungakhiwe ngendlela engafanele lungabangela ukulimala kokubunjwa, kukhinyabeze ukukhiqiza komthombo nokuphila isikhathi eside.Ukulawula ukwakheka koketshezi kanye nezakhiwo zokuhlunga kubalulekile ukuze unciphise le ngozi.
Ukulahlekelwa Uketshezi: Ukulahlekelwa uketshezi, noma ukungena koketshezi lokumba ekubunjweni, kungaholela ekungazinzini kwe-wellbore, ukulahlekelwa ukujikeleza kwegazi, kanye nokunciphisa ukusebenza kahle kokumba.Ukufaka ama-ejenti okulawula ukulahlekelwa kwamanzi asebenzayo kubalulekile ukubhekana nalolu daba.
kuyilapho amagama athi “udaka lokubhoboza” kanye “noketshezi lokumba” evame ukusetshenziswa ngokushintshana, angabhekisela ekwakhiweni okuthe ukuhluka kanye nezinhlelo zokusebenza ngaphakathi komongo wemisebenzi yokumba.Uketshezi lokumba lusebenza njengento eguquguqukayo ebalulekile ekumbiweni kwe-borehole, lunikeza imisebenzi efana nokuthambisa, ukuthuthwa kokusika, nokuzinza kwe-wellboe.Kungakhathaliseki ukuthi kusekelwe emanzini, ku-oyela, noma okokwenziwa, ukwakheka koketshezi lokumba kwenzelwa ukuhlangabezana nezinselele ezithile zokumba kuyilapho kulandelwa imithetho yemvelo.Ngokuqonda ubunkimbinkimbi bokwakheka nokuziphatha koketshezi olumbayo, onjiniyela bokubhola kanye nabaqhubi bangakwazi ukuthuthukisa ukusebenza kokumba kuyilapho benciphisa umthelela wendawo futhi baqinisekise ubuqotho bokusebenza kahle.
