Njengoko sonke siyazi, ukukhethwa kwamacandelo abalulekileyo kwi-rotary drilling rig inquma ngokuthe ngqo ubomi bayo benkonzo. Kule nto, uSinovo, umenzi we-rotary drilling rig, uya kwazisa indlela yokukhetha ii-emele zokubhola.
1. Khetha iibhakethi zokuqhuba ngokweemeko zejoloji
Umsebenzi ophambili weIsixhobo sokubhola esijikelezayokukwenza umngxuma phezu komhlaba, kwaye into esebenzayo iliwa. Ngenxa yobunzulu obuncinci bomngxunya owenziweyo, ilitye liye lafumana utshintsho oluntsonkothileyo kwisakhiwo, ubungakanani bamasuntswana, i-porosity, i-cementation, ukwenzeka kunye namandla oxinzelelo ngokushukuma kwetectonic kunye nentshukumo yendalo yomatshini kunye neekhemikhali, ngoko ke into esebenzayo yerotary drilling rig. inzima ngakumbi.
Ukushwankathela, kukho ezi ndidi zilandelayo.
Ngokutsho kwe-lithology, ihlukaniswe yaba yi-shale, ilitye lesanti, i-limestone, i-granite, njl.
Ngokutsho kwe-genesis, inokwahlulwa ibe yi-magmatic rock, i-sedimentary rock kunye ne-metamorphic rock;
Ngokweempawu zemishini, ihlukaniswe ibe yinyani, iplastiki kunye nekhululekile. Ke indlela yokukhetha i-drill bit ngokwemiqathango yokwakheka? Oku kulandelayo yintshayelelo ehleliweyo:
(1) Udongwe: Ibhakethi yokubhola ejikelezayo ene-single-layer bottom ikhethiwe. Ukuba i-diameter incinci, iibhakethi ezimbini okanye ibhakethi yokwemba enepleyiti yokukhulula ingasetyenziswa.
(2) Udaka, umaleko womhlaba obambeneyo obuthathaka, umhlaba oyintlabathi kunye nomaleko wengqalutye onesamente engekho mgangathweni kunye nobukhulu bamasuntswana amancinane unokuxhotyiswa nge-emele yokomba ephantsi kabini.
(3) Imastic eqinileyo: ibhakethi yokomba ejikelezayo enendawo enye yomhlaba (umzantsi omnye kunye nambini) okanye isikrufu esithe ngqo esinamazinyo eemele siyakunyulwa.
4 Kufuneka kuqatshelwe ukuba i-auger bit iyasebenza kumaleko womhlaba (ngaphandle kodaka), kodwa kufuneka isetyenziswe xa kungekho manzi aphantsi komhlaba ukunqanda ukuminxeka okubangelwa kukufunxa.
(5) Amatye engqalutye kunye neegrabile ezenziweyo kunye namatye agqunywe ngamandla: i-conical bit spiral kunye ne-double bottom ye-emele yokomba ejikelezayo iya kuxhotyiswa (izibuko elinye lobukhulu bamasuntswana amakhulu kunye nezibuko eliphindwe kabini lesayizi yamasuntswana amancinci)
(6) I-stroke bedrock: ixhotyiswe ngepick barrel bit coring bit - conical spiral bit - i-emele yokomba ejikelezayo enomzantsi ophindwe kabini, okanye chola ibhakethi elijikelezayo lokubhola elinomzantsi ophindwe kabini.
7 Ukuba ububanzi bukhulu kakhulu, kuya kwamkelwa inkqubo yokwemba.
