Ubuchwepheshe Bokubhoboza Okuqondisayo ； Ipayipi Lokubhoboza ； Ukusikwa Kokubhoboza

Ubuchwepheshe bokubhoboza ngendlela eqondisayo buyindlela ethuthukisiwe yokubhoboza esebenzisa amathuluzi akhethekile okudonsa phansi kanye namasu okulawula ukulinganisa ukuze kwandiswe indlela yokubhoboza ngendlela eklanywe kusengaphambili (engaqondile) eya ekwakhekeni kwenhloso. Ingqikithi yokubhoboza ngendlela eqondisayo iwukulawula ngenkuthalo indlela yokubhoboza. Umqondo wayo oyinhloko uhilela ukuqondisa i-drill bit endaweni eqondiwe ngenqubo evaliwe 'yokulinganisa - ukuhlola - ukulungiswa'. Le ndlela inqoba imikhawulo yokubhoboza ngendlela eqondile yendabuko, engaqhubeka kuphela ngomugqa wokulinganisa, okwenza kube lula 'indawo eqondile kanye nokukhishwa' kwezinsizakusebenza ezingaphansi komhlaba. Imi njengobunye bobuchwepheshe obuyinhloko emikhakheni efana nokuhlola nokuthuthukiswa kukawoyela negesi, ubunjiniyela be-geological, kanye nokukhishwa kwezimbiwa.

Ubuchwepheshe bokubhoboza obuqondisa izinto buyithuluzi elibalulekile ekuthuthukisweni kwamandla kwanamuhla kanye nobunjiniyela be-geological. Intuthuko yalo inquma ngqo ikhono kanye nokusebenza kahle kokusetshenziswa kwezinsiza ezingaphansi komhlaba. Ukuqhubekela phambili, luzodlala indima ebaluleke kakhulu ekuthuthukisweni kwezinsiza ezijulile, ukuthuthukiswa okuhlakaniphile, kanye nokusetshenziswa kwemikhakha ehlukahlukene.

Amapayipi okubhobozazisebenza njengezingxenye eziyinhloko zeshubhu emisebenzini yokubhoboza (kufaka phakathi ukubhoboza okuqondiswayo, ukubhoboza umthombo oqondile, njll.), amandla okudlulisa, ukudlulisa uketshezi lokubhoboza, kanye namathuluzi okuxhumanisa imigodi ephansi. Njengezinto eziyinhloko zentambo yokubhoboza (ehlanganisa amapayipi okubhoboza, amakhola okubhoboza, izingcezu zokubhoboza, njll.), zithinta ngqo ukusebenza kahle kokubhoboza, ikhwalithi ye-wellbor, kanye nokuphepha kokusebenza.

Umsebenzi oyinhloko wamapayipi okubhoboza ukusebenza njengesixhumanisi phakathi kwezingxenye eziphezulu nezingezansi. Axhuma phezulu endaweni yokubhoboza engaphezulu, athole i-torque kanye nengcindezi yokubhoboza evela endaweni yokubhoboza; phansi ukuze axhumane namathuluzi okudonsa phansi njengemigoqo yokubhoboza nama-bits, adlulisele amandla ku-bit ukuze kungene edwaleni. Ngesikhathi esifanayo, isakhiwo sawo esingenalutho sidlulisa uketshezi lokubhoboza (udaka) ukuze lupholise i-bit, lugcobe intambo yokubhoboza, futhi luthuthe izingcezu ezivela emgodini womthombo ziye endaweni engaphezulu.

Amapayipi okubhoboza aqukethe izingxenye ezimbili: umzimba kanye nejoyinti. Lawa ahlanganiswa ngokushisela okungqubuzanayo, okudinga amandla aphezulu kanye nezakhiwo zokuvala eziphakeme ukuvimbela ukuvuza koketshezi lokubhoboza noma ingcindezi engalawuleki yomgodi ophansi.

Izicucu zokubhoboza zakha ingxube yezinhlayiya eziqinile ezikhiqizwa lapho i-drill bit iphula idwala elingaphansi komhlaba ngesikhathi senqubo yokubhoboza. Zimelela umkhiqizo oqondile wemisebenzi yokubhoboza futhi zisebenza njengokugxila okuyinhloko kokuhlolwa kwe-geological, ukulawulwa kokuphepha kwe-wellbore, kanye nokuphathwa kwemvelo. Empeleni, izicucu zokubhoboza 'ziyimfucumfucu yamadwala aqhekekile' ekhiqizwa kanyekanye nenqubo yokubhoboza. Azigcini nje ngokuthwala ulwazi olubalulekile mayelana ne-subsurface strata, kodwa ukusebenza kahle kokucubungula kwazo kanye nesimo kuthinta ngqo ukuphepha kanye nomnotho wemisebenzi yokubhoboza.

Izinto eziyinhloko ezisetshenziswayo zihlanganisa amatshe okwakheka (njengetshe lesihlabathi, itshe lodaka, i-limestone, i-granite, njll.), okungenzeka kuxutshwe nenani elincane lezithasiselo zoketshezi lokubhoboza (isb., ubumba, ama-polymer) kanye nemfucumfucu yensimbi (isb., izinhlayiya zokuguguleka kwe-drill bit, imikhiqizo yokugqwala kwepayipi lokubhoboza). Ukubhoboza okusikiwe akuzona nje 'izinto ezilahliwe' kodwa kunalokho kusebenza 'njengabathwali bolwazi' ababalulekile kanye 'nezinkomba zesimo sokusebenza' emisebenzini yokubhoboza.

Uma izicucu zingabuyiselwa ngokushesha kusuka emgodini womthombo ziye endaweni engaphezulu, zingase ziqongelelane ngaphakathi kwembobo, okungase kubangele izehlakalo zokuphepha ezinkulu. Ngenxa yalokho, 'ukuthuthwa nokususwa kwazo' kungenye yemisebenzi eyinhloko yoketshezi lokubhoboza. Izici zoketshezi lokubhoboza—njengobukhulu bezinhlayiya kanye nezinga lokuqhekeka—zinganikeza ukuqonda okuqondiswe emuva mayelana nokuqonda kwemingcele yokubhoboza, ngaleyo ndlela kusize ekwenzeni ngcono ukusebenza kahle. Lapho zilethwa phezu koketshezi lokubhoboza, izicucu zidlula ezigabeni ezintathu eziyinhloko: ukuhlukaniswa, ukuhlaziywa, kanye nokulahla, okwakha umjikelezo wokucubungula ophelele.
