Njengoba sonke sazi, ukukhethwa kwezingxenye ezibalulekile ze-rotary drilling rig kunquma ngqo impilo yayo yokusebenza. Ngenxa yalokhu, i-Sinovo, umenzi we-rotary drilling rig, izokwethula indlela yokukhetha amabhakede okubhoboza.
1. Khetha amabhakede okubhoboza ngokwezimo zejoloji
Umsebenzi oyinhloko we-umshini wokubhoboza ojikelezayoiwukwakha umsele wembobo ebusweni, kanti into esebenzayo yidwala. Ngenxa yokujula okuncane kwembobo yenqwaba eyakhiwe, idwala liye labhekana nezinguquko eziyinkimbinkimbi esakhiweni, usayizi wezinhlayiya, ukubhoboka, ukuhlanganiswa kwesimende, ukwenzeka kanye namandla okucindezela ngokuhamba kwe-tectonic kanye nesenzo semvelo somshini kanye namakhemikhali, ngakho-ke into esebenzayo ye-rotary drilling rig iyinkimbinkimbi kakhulu.
Ngamafuphi, kunezigaba ezilandelayo.
Ngokusho kwe-lithology, ihlukaniswe nge-shale, i-sandstone, i-limestone, i-granite, njll.
Ngokusho kwe-genesis, ingahlukaniswa ibe yidwala le-magmatic, idwala le-sedimentary kanye nedwala le-metamorphic;
Ngokwezakhiwo zemishini, ihlukaniswe yaba eqinile, ipulasitiki kanye nekhululekile. Ngakho-ke ungayikhetha kanjani i-drill bit ngokwezimo zokwakheka? Okulandelayo yisingeniso esihlukanisiwe:
(1) Ubumba: kukhethwa ibhakede lokubhoboza elijikelezayo elinephansi elinongqimba olulodwa. Uma ububanzi buncane, kungasetshenziswa amabhakede amabili noma ibhakede lokubhoboza elinepuleti lokulayisha.
(2) Udaka, ungqimba lomhlabathi olubuthakathaka oluhlangene, inhlabathi enesihlabathi kanye nongqimba lwamatshe amancane olune-cementation embi kanye nosayizi wezinhlayiya ezincane kungafakelwa ibhakede lokubhoboza elingaphansi eliphindwe kabili.
(3) I-mastic eqinile: ibhakede lokubhoboza elijikelezayo elinokungena komhlabathi okukodwa (iphansi elilodwa neliphindwe kabili) noma isikulufu esiqondile esinamazinyo ebhakede kufanele sikhethwe.
(4) Ingqimba ye-permafrost: ibhakede le-auger eliqondile kanye nebhakede lokubhoboza elijikelezayo lingasetshenziswa kulabo abanokuqukethwe okuncane kweqhwa, kanti i-conical auger bit ingasetshenziswa kulabo abanokuqukethwe okukhulu kweqhwa. Kufanele kuqashelwe ukuthi i-auger bit iyasebenza engqimbeni yomhlabathi (ngaphandle kodaka), kodwa kumele isetshenziswe lapho kungekho amanzi angaphansi komhlaba ukuze kugwenywe ukuminyana okubangelwa ukumuncwa.
(5) Amatshe amancane aqinisiwe kanye namatshe agugile kakhulu: kufanele kufakwe ibhakede lokubhoboza eliyindilinga eliyindilinga kanye nebhakede lokubhoboza elijikelezayo elingaphansi eliphindwe kabili (imbobo eyodwa yobukhulu bezinhlayiya ezinkulu kanye nembobo ephindwe kabili yobukhulu bezinhlayiya ezincane)
(6) Isisekelo sedwala: sihlonyiswe nge-pick barrel coring bit - i-conical spiral bit - ibhakede lokubhoboza elijikelezayo eline-bottom double, noma i-pick straight spiral bit - ibhakede lokubhoboza elijikelezayo eline-bottom double.
(7) Idwala eligugile kancane: lifakwe i-coring bit ye-cone barrel - i-conical spiral bit - ibhakede lokubhoboza elijikelezayo elingaphansi kabili. Uma ububanzi bukhulu kakhulu, inqubo yokubhoboza ehlelwe ngokwezinga kufanele ilandelwe.
