Njengoko sonke sisazi, ukukhethwa kweendawo ezibalulekileyo zerotary drill rig kumisela ngokuthe ngqo ubomi bayo benkonzo. Ngenxa yesi sizathu, iSinovo, umenzi werotary drill rig, iza kwazisa indlela yokukhetha iibhakethi zokubhola.
1. Khetha iibhakethi zokubhola ngokweemeko zejoloji
Umsebenzi ophambili weisixhobo sokugrumba esijikelezayoyenzelwe ukwenza umngxuma phezu komphezulu, kwaye into esebenzayo lilitye. Ngenxa yobunzulu obuncinci bomngxuma wenqwaba owakhiweyo, ilitye liye latshintsha kakhulu isakhiwo, ubungakanani bamasuntswana, ukubola, ukuqina, ukwenzeka kunye namandla okucinezelwa ngentshukumo ye-tectonic kunye nentshukumo yendalo yoomatshini kunye neekhemikhali, ngoko ke into yokusebenza yerotary drilling rig iyinkimbinkimbi kakhulu.
Ukushwankathela, kukho ezi ndidi zilandelayo.
Ngokwe-lithology, yahlulwe yaba yi-shale, i-sandstone, i-limestone, i-granite, njl.
Ngokwe-genesis, inokwahlulwa ibe yi-magmatic rock, i-sedimentary rock kunye ne-metamorphic rock;
Ngokweempawu zoomatshini, yahlulwe yaba lukhuni, iplastiki kunye nekhululekileyo. Ngoko ke ungayikhetha njani i-drill bit ngokweemeko zokwakheka? Oku kulandelayo yintshayelelo ehleliweyo:
(1) Udongwe: kukhethwa ibhakethi yokugrumba ejikelezayo enezantsi elinomgangatho omnye. Ukuba ububanzi buncinci, kungasetyenziswa ibhakethi ezimbini okanye ibhakethi yokugrumba enepleyiti yokukhupha impahla.
(2) Udaka, umaleko womhlaba odibeneyo obuthathaka, umhlaba onesihlabathi kunye nomaleko welitye elincinci onesamente embi kunye nobukhulu obuncinci bamasuntswana bunokuxhotyiswa ngebhakethi yokugrumba engaphantsi kabini.
(3) I-mastic eqinileyo: Ibhakethi yokubhola ejikelezayo ene-inlet yomhlaba omnye (i-bottoms enye ne-double bottoms) okanye isikrufu esithe tye esinamazinyo ebhakethi kufuneka sikhethwe.
(4) Umaleko onomkhenkce ongapheliyo: ibhakethi ye-auger ethe tye kunye nebhakethi yokubhola ejikelezayo zingasetyenziselwa abo banomkhenkce omncinci, kwaye i-conical auger bit ingasetyenziselwa abo banomkhenkce omninzi. Kufuneka kuqatshelwe ukuba i-auger bit iyasebenza kumaleko womhlaba (ngaphandle kodaka), kodwa kufuneka isetyenziswe xa kungekho manzi angaphantsi komhlaba ukuze kuthintelwe ukuxinana okubangelwa kukufunxa.
(5) Iingqalutye eziqinisiweyo kunye neegrabile kunye namatye agutyungelwe ngamandla: i-conical spiral bit kunye ne-double bottom rotary drilling bucket kufuneka zixhotyiswe (i-single port yobukhulu be-particle enkulu kunye ne-double port yobukhulu be-particle encinci)
(6) Ilitye eliqinileyo: lixhotyiswe nge-pick barrel coring bit - i-conical spiral bit - ibhakethi yokugrumba ejikelezayo enezantsi eliphindwe kabini, okanye i-pick straight spiral bit - ibhakethi yokugrumba ejikelezayo enezantsi eliphindwe kabini.
(7) Ilitye eligutyungelwe kancinci: lixhotyiswe nge-cone barrel coring bit - i-conical spiral bit - ibhakethi yokubhola ejikelezayo ephindwe kabini. Ukuba ububanzi bukhulu kakhulu, kuya kusetyenziswa inkqubo yokubhola ehleliweyo.
