Installation ntawm Rotary Drilling cuab yeej

Cov cuab yeej drilling muaj qee qhov nruj thiab tsis txav los yog co thaum lub sijhawm drilling lossis lwm yam haujlwm. Lub installation ntawm cov cuab yeej drilling yuav tsum ua raws li cov chaw tsim khoom cov qauv. Thaum lub sij hawm tsim kho, ntau yam tshwj xeeb ntawm cov khoom laum xws li luv luv kauv xyaum, cov thoob teb, cov tub ntxhais xyaum, thiab cov tub ntxhais ua teb tuaj yeem siv tau. Thaum lub sij hawm tsim kho, sib txawv laum me me rau cov tshuab drilling tshuab raug xaiv raws li cov kev cai nram qab no raws li cov av sib txawv thiab geological tej yam kev mob: luv spiral drilling cuab yeej, haum rau cohesive av, silt, sau saum toj no dej hauv av, nruab nrab tuab xuab zeb thiab weathered pob zeb txheej. Kauv tig taub hau, siv cov av nkos phab ntsa tiv thaiv, haum rau cohesive av, silt, xuab zeb, sau, gravel av, thiab weathered pob zeb txheej saum toj no dej hauv av. Pob zeb core kauv laum khoom yog tsim rau gravel av, nruab nrab hardness pob zeb, thiab weathered pob zeb txheej. Core laum khoom yog tsim rau huab cua txheej pob zeb thiab cov pob zeb tawg. Cov kev qhia tshwj xeeb ntawm cov khoom siv tho yog xaiv thiab sib tw los ntawm tus neeg siv raws li qhov tseeb engineering teeb meem.
