Njengoba sonke sazi, ukukhethwa kwezingxenye ezibalulekile ze-rotary drilling rig kunquma ngokuqondile impilo yayo yesevisi. Kulokhu, iSinovo, umkhiqizi we-rotary drilling rig, uzokwethula indlela yokukhetha amabhakede okubhola.
1. Khetha amabhakede okubhola ngokuya ngezimo ze-geological
Umsebenzi oyinhloko weI-Rotary drilling rigukwenza umsele wembobo ngaphezulu, futhi into esebenzayo idwala. Ngenxa yokujula okuncane kwembobo yenqwaba eyakhiwe, idwala liye laba nezinguquko eziyinkimbinkimbi ekwakhekeni, usayizi wezinhlayiya, i-porosity, usimende, ukwenzeka namandla okucindezela ngokusebenzisa ukunyakaza kwe-tectonic kanye nesenzo semvelo somshini namakhemikhali, ngakho-ke into esebenzayo ye-rotary drilling rig. iyinkimbinkimbi ikakhulukazi.
Ukufingqa, kunezigaba ezilandelayo.
Ngokusho kwe-lithology, ihlukaniswe nge-shale, i-sandstone, i-limestone, i-granite, njll.
Ngokusho kwe-genesis, ingahlukaniswa ngamatshe amakhulu, idwala le-sedimentary kanye nedwala le-metamorphic;
Ngokusho kwezakhiwo zemishini, ihlukaniswe yaba iqinile, ipulasitiki futhi ikhululekile. Ngakho-ke ungakhetha kanjani i-drill bit ngokuya ngezimo zokwakheka? Okulandelayo yisingeniso esihlukanisiwe:
(1) Ubumba: ibhakede lokumba elijikelezayo elinesendlalelo esisodwa phansi likhethiwe. Uma ububanzi buncane, amabhakede amabili noma ibhakede lokubhola elinepuleti lokuthulula lingasetshenziswa.
(2) Udaka, ungqimba lwenhlabathi ehlangene olubuthaka, inhlabathi eyisihlabathi kanye nongqimba lwamatshana olunosimende olungeluhle kanye nosayizi omncane wezinhlayiyana kungafakwa ibhakede lokumba elingaphansi eliphindwe kabili.
(3) I-mastic eqinile: ibhakede lokumba elijikelezayo elinendawo eyodwa yomhlabathi (iphansi elilodwa neliphindwe kabili) noma isikulufu esiqondile esinamazinyo ebhakede sizokhethwa.
(4) I-Permafrost layer: ibhakede le-auger eliqondile kanye nebhakede lokumba elijikelezayo lingasetshenziswa kulabo abaneqhwa elincane, futhi i-conical auger bit ingasetshenziswa kulabo abaneqhwa elikhulu. Kufanele kuqashelwe ukuthi i-auger bit iyasebenza ongqimbeni lwenhlabathi (ngaphandle kodaka), kodwa kufanele isetshenziswe lapho engekho amanzi angaphansi komhlaba ukugwema ukuminyana okubangelwa ukumuncwa.
(5) Amatshe amatshe anosimende namatshe aqine kakhulu: i-conical spiral bit kanye nebhakede lokumba elijikelezayo eliphansi eliphindwe kabili kufanele kufakwe (imbobo eyodwa yosayizi wezinhlayiyana ezinkulu kanye nembobo ephindwe kabili yosayizi wezinhlayiyana ezincane)
(6) I-Stroke Bedrock: ifakwe i-pick barrel coring bit - i-conical spiral bit - ibhakede lokubhola elijikelezayo elinephansi eliphindwe kabili, noma khetha i-spiral bit eqondile - ibhakede lokubhola elijikelezayo elinephansi eliphindwe kabili.
(7) Itshe elingaphansi eliqinile: lifakwe i-cone barrel coring bit - i-conical spiral bit - ibhakede lokubhola elijikelezayo eliphansi eliphindwe kabili. Uma ububanzi bukhulu kakhulu, inqubo yokumba esezingeni kufanele yamukelwe.
