Sesiphi isixhobo ekufuneka sisetyenziselwe ukugrumba kwi-geology enemozulu enamandla

1. I-drilling rig ixhotyiswe nge-friction okanye i-kelly bar edibeneyo, enokuthi ihlangabezane nobubanzi bemfumba kunye nobude bemfumba.

2. I-Kelly Bar: khetha uhlobo lombhobho wokubhobhoza ngokokomelela kwelitye eligutyungelwe ngamandla (imitha e-1 yemitha yemfumba yedayamitha, umzekelo), elona nqanaba lokuthwala lingaphantsi kwe-500 kPa kunye ne-friction kelly bar; ngaphezulu kwe-500 kPa enebha edityanisiweyo ye-kelly.

3. Izixhobo zokomba: Uninzi lwamatye agrunjwe ngamandla angonjwa nge-emele engaphantsi kabini yamazinyo embumbulu; izixhobo zokomba ezine-cone-cone spiral zingasetyenziselwa ukomba owomileyo. Xa amandla okuthwala ekugqibeleni aphakama ukuya kwi-600 kPa-900 kPa, kuyimfuneko ukusebenzisa i-cartridge drill yokusika i-ring, kodwa akunakwenzeka ukuthatha ii-cores, ngoko ke kuyimfuneko ukusebenzisa ukutyumza kabini phantsi kwakhona.

4. Amazinyo okugaya: 30/50.22 mm bullet amazinyo kunye ne-4S bullet amazinyo esikhokelo asetyenziselwa ukugrumba kwimozulu eyomeleleyo, enceda ukutyumza, ukunciphisa ukuxhathisa ukugrunjwa, kunye nokunciphisa ngempumelelo ilahleko.
