Kab rov tav Directional Drilling Tshuab ua haujlwm txoj cai thiab txheej txheem
Dec 01, 2022| 1. Txoj kev tsim kho ntawm Kab rov tav Directional Drilling Tshuab thiab directional drillin
Pilot drilling yog feem ntau ua nrog 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 cov 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 Directional Drilling Tshuab
Qhov zoo: kev cuam tshuam me me rau saum npoo, kev tsim kho ceev ceev, tswj cov kav dej tso kev taw qhia, thiab 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.
