Lub hauv paus ntsiab lus ua haujlwm thiab txheej txheem ntawm kab rov tav directional drilling yog dab tsi?
May 29, 2023| 1 Kev tsim kho lub hauv paus ntsiab lus ntawm kab rov tav directional drilling thiab pilot drilling Guided drilling yog tsuas yog ua tiav los ntawm dav hlau-pab txiav cov khoom. Yog hais tias lub laum txoj hlua yog pub thiab tig tib lub sij hawm, lub ramp poob nws directionality thiab enables ib tug straightened qhov; Yog tias txoj hlua laum tsuas yog tig, cov tshuaj tiv thaiv quab yuam ua rau ntawm txoj hlua ua rau me ntsis hloov kev taw qhia. Muaj ib tug sojntsuam los yog transmitter nyob rau hauv lub pilot ntsis.
2 Qhov zoo thiab qhov tsis zoo ntawm kab rov tav kev taw qhia qhov zoo: tsawg cuam tshuam rau saum npoo, kev tsim kho ceev ceev, tswj tau cov kev taw qhia ntawm cov raj xa dej, kev tsim kho siab. Disadvantages: Qhov chaw tsim kho yuav tsum tau ntau, nws yog ib qho nyuaj rau tsim nyob rau hauv uas tsis yog-cohesive av thiab gravel txheej, thiab nws yog feem ntau haum rau ntau yam av txheej tsis muaj pebbles loj.
3 Kab rov tav directional drilling kev tsim kho txheej txheem Kev tsim kho → ntsuas thiab teeb tsa → khoom siv teeb tsa → drilling rig anchoring → av nkos npaj → pilot qhov kev tsim kho → qhov reaming siv → yeeb nkab rub rov qab.
