Umehluko Phakathi Kwepayipi Lokubhoboza kanye Nekhola Yokubhoboza

Amapayipi okubhoboza namakholola angamathuluzi abalulekile embonini kawoyela. Lesi sihloko sizokwethula umehluko phakathi kwale mikhiqizo emibili.

I-Drill Collars

Amakholomu okubhola atholakala ngaphansi kwentambo yokubhoboza futhi ayingxenye eyinhloko yomhlangano wembobo engezansi (BHA). Izici zabo eziyinhloko izindonga zabo eziwugqinsi (ngokuvamile 38-53mm, okuwugqinsi izikhathi ezingu-4-6 kunezindonga zamapayipi okubhoboza), ezinikeza isisindo esikhulu kanye nokuqina. Ukuze kube lula ukusebenza kokumba, ukuphakamisa izisele kanye nemisele eshelelayo kungenziwa ngomshini endaweni engaphandle yemicu yangaphakathi yekhola yokubhoboza.

Gcoba Amapayipi

Amapayipi okubhoboza amapayipi ensimbi aneziphetho ezinentambo, asetshenziselwa ukuxhuma impahla engaphezulu yensimbi yokubhoboza nezinto zokumba noma ukuhlanganiswa kwembobo engezansi phansi komthombo. Inhloso yamapayipi okubhoboza iwukuhambisa udaka lokumba luyise endaweni yokubhoboza nokusebenza ne-drill bit ukuze ukhuphule, ukwehlisa, noma ukuzungezisa ukuhlanganiswa kwembobo engezansi. Amapayipi okubhoboza kufanele amelane nezingcindezi ezinkulu zangaphakathi nangaphandle, ukugoqa, nokudlidliza. Ngesikhathi sokukhishwa nokucwengisiswa kukawoyela negesi, amapayipi okubhola angasetshenziswa kabusha izikhathi eziningi. Amapayipi okubhoboza ahlukaniswe ngamapayipi okubhoboza isikwele, amapayipi ajwayelekile okubhoboza, namapayipi esindayo sokubhola.

Izindima Ezihlukene Embonini Kawoyela Negesi
Lawa mathuluzi amabili anezinjongo ezahlukene ekukhishweni kukawoyela negesi. Amakholomu okubhoboza amapayipi ensimbi anezindonga eziwugqinsi asetshenziselwa ngokuyinhloko ukwengeza isisindo entanjeni yokubhoboza, anikeze ukucindezela okukhulu kokubhoboza nokuvimbela ukuchezuka komthombo. Amapayipi okubhoboza, ngakolunye uhlangothi, amapayipi ensimbi anezindonga ezincane ezisetshenziswa ngokuyinhloko ukudlulisa i-torque noketshezi lokubhoboza ukuze akwazi ukuzungezisa nokubhoboza ibhithi lokubhoboza.

Kafushane, amakholomu okubhoboza, anesisindo esikhulu nokuqina kwawo, ahlinzeka ngesisindo esengeziwe kanye nokuzinza entanjeni yokubhola, kuyilapho amapayipi okubhoboza anesibopho sokudlulisa amandla emishini kanye nokuthutha udaka lokumba. Lawa mathuluzi amabili asebenza ndawonye ukuze aqinisekise ukusebenza kahle kwemisebenzi yokumba.
