Izicelo ze-Tricone Drill Bits Ezimweni Ezihlukile.
1.Soft Formations
Ukwakheka kobumba nodaka:Izinyo lensimbiama-tricone drill bitszifaneleka kakhulu ukwakheka okuthambile njengobumba netshe lodaka ngenxa yokuqina kwazo okuphansi. I-Three Cones drill Bit ingasika kalula futhi iphule idwala. Ukuma kwamazinyo kungaklanyelwa ukukhuhla nokugunda, ngakho-ke ngesikhathi sokubhoboza, asebenza njengefosholo ukuze asuse idwala elithambile. Ngaphezu kwalokho, kulokhu kwakheka, amandla omthelela kubhithi lokubhoboza aphansi, okuvumela amazinyo ensimbi ukuthi aphule kahle idwala ngaphandle kokuguga ngokweqile.
I-Sandy Soft Formations:Ama-TCI Drill Bits nawo ayasebenza ekwakhekeni kwesihlabathi ngezinhlayiya ezinhle kanye nokungasindisi kahle. Ekwakhekeni okunjalo, ukugingqika kwe-cone kanye nesenzo sokugunda kwamazinyo kukhulula izinhlayiya zesihlabathi, i-Tricone Rock Bit ekhishwa emgodini uketshezi lokumba. Kodwa-ke, uma kuqhathaniswa nobumba netshe lodaka, izinhlayiya zesihlabathi zingase zibangele ukuguga okuthile emazinyweni, ngakho ukukhetha kwe-Tricone Rotory Drill Bits kufanele kuncike ezicini ezithile zesihlabathi (ezifana nosayizi wezinhlayiyana, ubulukhuni, njll.). Ngenjwayelo,izinsimbi zokubhoboza izinyo lensimbizisafaneleka.
2.Medium-Hard Formations
Ukwakheka kwe-Sandstone:Ngokwakheka kwe-sandstone, ukukhethwa kwe-bit kuncike ebukhuni be-sandstone. Okwesanti esiqinile esilinganiselwe futhi esiqinile, a i-tungsten carbide insert (TCI) i-tricone drill bitngokuvamile inketho engcono kakhulu. Ukufakwa kwe-carbide eqinile kungamelana nokuguga kanye nomthelela we-sandstone, kuyiphule ngokugingqika kwama-cones kanye nomthelela kanye nezenzo zokuchoboza amazinyo. Ngesikhathi esifanayo, uketshezi lokumba luphuma ngemibhobho ukuze lupholise i-API ejwayelekile ye-tricone bit futhi luthwale izinhlayiya ze-sandstone eziphukile, kuqinisekiswe ukuthi kancane kusebenza kahle.
Ukwakheka kwe-Limestone:I-Tungsten carbide insert TCI tricone bit nayo ifanele ukwakheka kwe-limestone. Nakuba i-limestone inobunzima obuthile, akunzima ukuphuka njengamatshe aqine kakhulu. Ukufakwa kwe-carbide ngokuphumelelayo kwephula i-limestone ngokusebenzisa ukunyakaza okuhlanganisiwe kwamakhoni, ukusebenzisa umthelela nokucindezelwa. Ngesikhathi sokumba, uketshezi lokumba lupholisa kancane, luvimbele ukushisisa ngokweqile futhi luthwale izinhlayiya ze-limestone ezichotshoziwe ziphume emgodini.
3.Amanye Amafomu Aqinile (anemikhawulo ethile)
Amafomu e-Hard Shale:Ukuze kuqiniswe ukwakheka kwe-shale, insimbi yokubhoboza evalekile yamanzi egesi kawoyela enokufakwa kwe-tungsten carbide ingasebenza. Ukufakwa kwe-carbide kungaphula ngempumelelo i-shale, kuyilapho i-bearing evaliwe ivimbela izinhlayiya eziqinile oketshezini lokubhoboza ukuthi zingangeni kuma-bearings, ukuqinisekisa ukuthi ibhithi lisebenza ngokuzinza ngaphansi kwengcindezi ephakeme namandla omthelela. Kodwa-ke, izinga lokuguga lebhithi lingashesha ekubunjweni kwe-shale okuqinile uma kuqhathaniswa nokwakheka okuthambile nokuphakathi nendawo, ngakho-ke kuyadingeka ukuqapha isimo se-Isert Tooth Drill Bit futhi ulungise ishejuli yokushintsha ngokusekelwe ezicini ezifana nobulukhuni bokubunjwa nokujula kokumba.
Amafomu e-Hard Sandstone:Kwezinye izimo ze-sandstone eziqinile ezingaqinile ngokwedlulele, i-tungsten carbide ifaka i-tricone drill bit, kanye nemingcele efanele yokumba (njengejubane lokuzungezisa, isisindo kubhithi, njll.), isengasetshenziswa. Kodwa-ke, njengoba ukuqina kwe-sandstone kwanda, ukusebenza kahle kokumba kuzokwehla, futhi ukuguga emazinyweni kuzoqina. Ezimweni ezinjalo, kubalulekile ukuqapha ukusebenza kwebhithi eduze futhi ulungise imingcele yokumba njengoba kudingeka.
