Chifukwa Chiyani Rotary Drilling Rig Imakhala Ndi Zida Zina Pobowola?

Pamene chobowola chozungulira chikugwira ntchito, nthawi zonse pamakhala matope pansi pa dzenje, zomwe ndi vuto losapeŵeka la makina obowola rotary.Ndiye n'chifukwa chiyani ili ndi zinyalala pansi pa dzenje?Chifukwa chachikulu ndi chakuti njira yake yomanga ndi yosiyana.Chombo chobowola chozungulira chimagwiritsa ntchito njira yobowola matope osazungulira, ndipo slag yobowolayo siingatengedwe pansi ndi kuzungulira kwa matope kuti akhazikike.

Zifukwa zazikulu zomwe zimachitika ndi sediment ndi izi:
1. Zotsalira pakati pa mano a ndowa zobowolera mozungulira ndi chivundikiro chapansi cha chidebe chobowola
2.Mano ang'onoang'ono pobowola ma rotary ndi ochepa, kotero kuti sediment pakati pa mano ndi yosapeweka;
3.Chivundikiro chapansi cha chida chobowola sichimatsekedwa mwamphamvu;
4.Nthaka yodulidwa kuchokera m'mphepete mwa kunja kwa chidebe chobowola chozungulira sichingalowe m'kamwa mwa silinda chifukwa cha pansi pa dzenje ndipo imakhalabe pamphepete mwa dzenje;
5.Pobowola mchenga wamatope ndi mapangidwe a pulasitiki, slag yobowola mu chidebe chobowola imatayika panthawi yokweza, ndipo nthawi zina ngakhale zonse zimatayika mu borehole;
6.Kubwereranso kwa chidebe chobowola ndi chachikulu kwambiri, katunduyo ndi wodzaza kwambiri, ndipo matope amachotsedwa mu dzenje la ngalande la chivundikiro chapamwamba.

Malinga ndi muyezo wadziko lonse, chandamale makulidwe a matope pansi pa dzenje kwa mulu mikangano ndi mapeto kubala mulu si oposa 100mm ndipo osapitirira 50mm, motero.

Zomwe zili pamwambazi ndizifukwa zomwe zimapangidwira m'mabowo ang'onoang'ono obowola ang'onoang'ono opangidwa mwachidule ndi Gookma.Ngakhale kuti ichi ndi vuto losapeŵeka la zida zazing'ono zobowola mozungulira, zida zobowola mozungulira akadali makina oyenera kwambiri pobowola ndi kuyika milu pakali pano.
Pambuyo pobowola pobowola bowolo, tiyenera kuyeretsa dzenjelo, kuti matope omwe ali pansi pa dzenjelo achotsedwe.
