Izici, isimiso sokusebenza kanye nohla lokusebenzisa lwepayipi lokubhoboza onqenqemeni lwesithathu

Ipayipi lokubhoboza igesi elimaphethelo amathathu arc convex, elibizwa ngokuthi ipayipi lokubhoboza elimaphethelo amathathu.Umzimba wenduku emaphakathi wepayipi lokubhoboza elimaphethelo amathathu uwuhlobo lwe-arc olumaphethelo amathathu, futhi iziphetho ezimbili zingashiselwa ngokushisela i-friction ukuze kwakhe uhlobo lwe-arc olubukeka njengonxantathu, noma lucutshungulwe lube ohlotsheni oluphelele lwama-macho amathathu.

Izici:

1. Uhlobo lokuxhuma kwentambo ye-Taper

Ekwakhiweni kwesakhiwo, umzimba wenduku usebenzisa isakhiwo sephiramidi esingunxantathu, ekukhiqizeni nasekusetshenzisweni kubonisa izici zokonga amandla aphezulu, ngakho-ke kubizwa ngokuthi ipayipi lokubhoboza iphiramidi elingunxantathu.

Izinzuzo: ekusetshenzisweni kwemiphetho emithathu yomehluko wobubanzi obushukumisayo ukuze i-slag yamalahle inganciphisi ekuhambeni kokukhishwa okuphumelelayo, ekuklanyeni nasekuqinisekiseni ukuthi uhlobo olufanayo lokucaciswa kwentambo yepayipi lokuprakthiza lube lukhulu.

2. Uhlobo lokuxhuma lwesokhethi lwezindlela eziyisithupha

I-joint of drill pipe ithatha imodi yokuxhuma ye-square-square, ukuze i-torque kanye nezakhiwo eziphelele zemishini yepayipi yokubhoboza ngaphansi kwesimo sobubanzi obufanayo ingakwazi ukufeza ukucushwa okuphezulu, okubonisa umgomo wokuklama wokwandisa i-torque yepayipi yokubhoboza.

Izinzuzo: ukusetshenziswa koxhumano lwephinikhodi yokubhoboza ekhethekile evundlile entwasahlobo, gwema ngempumelelo uhlobo olucushiwe lwentambo yokubhoboza ebhajwe, isikulufu sekhanda esontekile.

Ngesikhathi esifanayo, ukufakwa nokuhlakazwa kwephini lokubeka ipayipi le-drill enezingqimba kulula futhi kusindisa isikhathi.Uma kuqhathaniswa nephinikhodi yokulungisa isikulufa noma ibholidi, ukusebenza kahle komsebenzi kuba ngcono kakhulu.

Umgomo wokusebenza kanye nobubanzi bokusetshenziswa kwepayipi lokubhoboza elimaphethelo amathathu

Ububanzi besicelo

Isetshenziswa kakhulu ekuhloleni amanzi emigodini ejulile kanye nokumba igesi ekwakhiweni kwestrata samadwala aqinile kanye namatshe amalahle emhubheni wezimayini zamalahle, futhi ingasetshenziswa ekwakhiweni kokumba phansi komgwaqo onguthelawayeka, ujantshi wesitimela neminye imiklamo yengqalasizinda.

Umgomo wokusebenza we

Uma kuqhathaniswa nepayipi lendabuko lokubhoboza, ipayipi lokubhoboza elimaphethelo amathathu enqubweni yokumba, ukunyakaziswa okusebenzayo kwe-slag yamalahle ezungeze ipayipi lokubhoboza ukwenza ukunyakaza kwe-axial, kanye ne-drill slag iyachotshozwa futhi iphakanyiswe, ukuze ibe sesimweni esimisiwe. , futhi ngeke kubonakale kunemvula, ukunqwabelana.

Ngaphansi komthelela we-radius ejikelezayo, yakha ipayipi lokubhoboza elingunxantathu elizocikwa ngokuqiniswa okuqhubekayo kwe-borehole odongeni, indlela yokuxhuma ipulaki esheshayo yohlobo lukanxantathu, ngokuya ngesimo sokumba okufika ngesikhathi futhi ubuyisele umshini wokubhola, ngaleyo ndlela unciphise kakhulu isenzakalo, esibangelwa ipayipi lokubhoboza imbobo, ukubamba ekufeni kwaziwa nangokuthi i-anti-lock drill pipe, gwema futhi unciphise ingozi yokuqhuma kwegesi, uthuthukise ukusebenza kahle kokukhiqiza.
