Ishubhu ehlanganisiwe, eyaziwa nangokuthi ishubhu eguquguqukayo, yenziwe ngeshubhu yensimbi ye-carbon alloy eguquguqukayo ukuze ihlangabezane nezidingo zokuguquguquka kwepulasitiki kanye nokuqina okudingekayo ekusebenzeni kwe-downhole.Ukucaciswa okujwayelekile kwamashubhu ahlanganisiwe yilezi: Phi 1/2 izingxenye ezintathu kwezine 3/8 25.4mm, φ31.75mm, φ38.1mm, φ44.45mm, φ50.8mm, φ60.325mm, φ66.675mm, 2φ5mm 2φ5mm .55mm, φ88.9mm, njll., khipha amandla 55000Psi~120000Psi.Amashubhu ahlanganisiwe, alinyazwa kurola futhi angaba amamitha ayizinkulungwane ezimbalwa ubude, angangena esikhundleni seshubhu elicushiwe elivamile ukuze lisebenze ngokuqhubekayo emgodini waphansi ngokucindezela.Amashubhu ahlanganisiwe asetshenziswe kabanzi ekubholeni, ekugawuleni, ekuqedeni, ekusebenzeni nasekusebenzeni, nokunye okwengeziwe ekuhloleni nasekuthuthukisweni kukawoyela negesi.
Nakuba izwe lethu laqala kudala ukusebenzisa ubuchwepheshe bamashubhu ahlanganisiwe emsebenzini ongaphansi komhlaba, kodwa ngenxa yethonya lezici ezihlukahlukene kubangele ukuthi ubuchwepheshe bamashubhu obuhlanganisiwe abutholanga ukuthuthukiswa okubanzi okudumile ezweni lakithi, inkolelo-mbono kanye nezinga lobuchwepheshe uma liqhathaniswa nentuthuko ethuthukisiwe. amazwe kusenegebe elithile, okuholela ekusetshenzisweni kwangempela ohlelweni lweshubhu elihlanganisiwe ukuze kusetshenziswe ngokugcwele inzuzo.Ngaphezu kwalokho, iningi lomsebenzi ongaphansi komhlaba ezweni lakithi ukhona ekusetshenzisweni kobuchwepheshe bokufaka amashubhu ahlanganisiwe ngobumpumputhe, alukho uhlelo lokwakha olunemininingwane ngaphambi kokusetshenziswa, njengokusetshenziswa kwemishini nezindlela zobuchwepheshe kanye nokusebenzisa uhla, okuholela ekusetshenzisweni kobuchwepheshe bokubopha amashubhu ahlanganisiwe. umsebenzi ongaphansi komhlaba ukuguquguquka okuphansi, ubuchwepheshe obuvamile ekusetshenzisweni kwemishini akubangeli izinkinga eziphelele, ubuqiniso bezinto zokusebenza Isimo sokusetshenziswa komhlaba wonke sidala ithonya elithile elibi.
Ukuguga okuhlobene kwemishini yokufaka amashubhu ehlanganisiwe
Njengamanje, iningi lemishini esetshenziswayo yasekhaya yokufaka amashubhu ahlanganisiwe iyimishini ethunyelwa kwamanye amazwe, okokusebenza kusalele emuva, okunye kwaze kwafinyelela umnqamulajuqu wokulahlwa.Ikhanda lomjovo, isivimbeli sokuvuthela, isistimu ye-hydraulic kanye nesistimu yokulawula egqoke izingxenye kunzima ukukubuyisela nokugcina.Ibanga elifanelekile lobubanzi beshubhu lincane, eminye imisebenzi ekhethekile yemigodi engaphansi ayihlangabezani nezidingo zokwakha.
Ukusetshenziswa kobuchwepheshe be-tubing obuhlanganisiwe
Ukusetshenziswa kwe-gas lift yokubuyisela uwoyela
Ubuchwepheshe bokubuyisela uwoyela we-gas lift ukujova igesi emthonjeni nokusebenzisa ukunwetshwa kwegesi ukunciphisa ukuminyana koketshezi oluxubile emthonjeni, ukuze uwoyela osemthonjeni uphume kalula.Ukusetshenziswa kobuchwepheshe bamashubhu ahlanganisiwe kuye kwalithuthukisa kakhulu inani lokubuyiselwa kukawoyela ongahluziwe kanye nezinga lobuchwepheshe bokubuyisela uwoyela.Ezindaweni eziningi, igesi ye-ammonia ijovwa phansi embobeni ngobuchwepheshe be-coiled tubing (CT) ukuze kuthuthukiswe ukutholakala kukawoyela negesi.
Kwambiwa Imithombo Emisha Eme mpo
Amashubhu amasha ahlanganisiwe I-Well ibholwa kusetshenziswa i-rig eyinhlanganisela ene-top drive ebholwa ngendlela evamile ekuqaleni kokumba.Lapho i-drill ifinyelela ekujuleni okuthile, ishintshela ekuboleni amashubhu asongelekile, ngemva kwalokho ingasebenzisa i-casing noma iqedele imbobo evuleke kahle.Ukumba okungaqondile kubala iningi lama-ct Wells amasha.
Izinzuzo ze-ct drilling Wells emisha ukuphepha, ukubhola okusheshayo (akukho collar), ukuhamba kalula, indawo encane, ukuzenzekelayo okuphezulu nokonga abasebenzi.Njengamanje, isivinini sokumba amashubhu ahlanganisiwe phesheya siyashesha kakhulu.Ngomthombo we-CBM wama-700m kuya ku-1000m, kuthatha izinsuku ezi-4 kuphela ukusuka ekuhlelweni kwemishini yokumba kuya ekukhishweni kwazo zonke izinto zokusebenza zokumba ngemva kokwakhiwa.I-Canada njengamanje iyisifunda esisebenza kakhulu emhlabeni jikelele sokumba amashubhu ahlanganisiwe.
Ukusebenza kwe-Downhole ezindaweni zikawoyela kuyingozi, futhi ukusetshenziswa kobuchwepheshe bamashubhu obunjiwe kudinga ubuchwepheshe kanye nezidingo eziqinile zokusebenza kwemishini.Ngokusebenzisa imishini ethuthukisiwe ehlukahlukene yokwenza imisebenzi ye-downhole ingathuthukisa ngempumelelo ukusebenza kahle, ukuze ukuphepha kwabasebenzi bokwakha kunikeze isisekelo sesiqinisekiso.Kodwa-ke, ukuze kuncishiswe isikhathi sokwakha, kuncishiswe izindleko futhi kuthuthukiswe inzuzo, iningi lamabhizinisi e-petroleum aseChina ayaqhubeka nokusungula ubuchwepheshe obuhlobene nokwakhiwa kwenqubo, kodwa ngesikhathi esifanayo, kusenezinkinga ezithile ekukhiqizeni imishini, ukuze inqubo iqhubeke. yokusebenza ngaphansi komhlaba, kukhona ukushoda okukhulu kwemishini.Ukuze kuthuthukiswe ukuthandwa okubanzi kobuchwepheshe be-tubing obuhlanganisiwe, okokuqala udinga uhlelo olunzulu lwemishini njengokwesekwa, ukuze izwe lethu liqinise ukukhiqizwa kwemishini ehlobene, landise ukutshalwa kwezimali, ukwenza imishini efanele kanye nezinsiza ukuhlangabezana nezidingo zentuthuko ezweni lethu, sithuthukise izinga lokusebenza nokusetshenziswa kwemishini, ngaleyo ndlela sinikeze isisekelo sokuqaliswa kwesiqinisekiso sobuchwepheshe bamashubhu ahlanganisiwe.
Ithemba lokuthuthukiswa kwamashubhu ahlanganisiwe
Ukuhlanganisa ukushiyeka kokusebenza kwamashubhu ahlanganisiwe, esigabeni sokugcina sokuthuthukiswa kwendawo kawoyela, thatha ukukhuphuka kobuchwepheshe obungcono kakhulu, ukwenza ngcono umphumela wokusetshenziswa kwamashubhu ahlanganisiwe, kwandisa amathuba okusebenza kweshubhu elihlanganisiwe, ukudlala ikhono lokusebenza kweshubhu elihlanganisiwe, ukuqinisekisa ukuqaliswa ngempumelelo komsebenzi ongaphansi komhlaba, ukusiza ukuwenza ube ngcono ekukhiqizeni indawo kawoyela.
Ithemba lokuthuthuka lamashubhu ahlanganisiwe esikhathini sakamuva liyahlaziywa ukuze kuthuthukiswe izinga lokuzenzekelayo lemishini yokulawula indawo yeshubhu ehlanganisiwe, kwandisa njalo izinyathelo zobuchwepheshe zokusebenza kwamashubhu ahlanganisiwe, ukuthuthukisa isivinini sokusebenza ngaphansi komhlaba nokwakha, kufinyeze isikhathi sokusebenza kanye ukwakhiwa, futhi uqinisekise ukuphothulwa ngokushelelayo kokusebenza nokwakhiwa komhlabathi.Amathuluzi okukhipha amanzi okucwaninga, alenze asebenzisane nezinyathelo zobuchwepheshe ezihlanganisiwe zamashubhu, athuthukise izinga lokusebenza kanye nokwakhiwa kweMithombo evundlile esigabeni sakamuva sokuthuthukiswa kwendawo kawoyela, thatha izinyathelo zobuchwepheshe ezingcono kakhulu zokuhlola kanye nokuvuselela amandla, ukuthuthukisa ukuphuma kwedamu, ukuhlangabezana nezidingo zokukhiqiza ukuthuthukiswa kwe-oilfield.
Ukuthuthukiswa okuqhubekayo kwezinto zokuhlanganisa amashubhu ahlanganisiwe, ukusetshenziswa kwezinto ezintsha kanye nobuchwepheshe obusha kubuchwepheshe bokusebenza kwamashubhu ahlanganisiwe, shintsha ububanzi noma ushintshe i-taper yokufaka amashubhu ahlanganisiwe, ukuxazulula izinkinga ezinzima zokusebenza okukhethekile kwemigodi ephansi.Ukusebenza nokwakhiwa kwe-downhole kalula ku-Deep Wells, kunciphisa ukuguga kumashubhu ahlanganisiwe futhi andise impilo yesevisi yamashubhu ahlanganisiwe.
