Yuav ua li cas kom tsis txhob yuam kev nyob rau hauv Kab rov tav Directional Drilling Rig Guide Angle Adjustment

I. Cov Ntsiab Cai Tiv Thaiv

1. Ua raws li lub hauv paus ntsiab lus ntawm kev nplua -tuning: Tswj qhov kev hloov ntawm inclination lub kaum sab xis thaum lub sij hawm kho ib zaug rau 2% ~ 4%, zam "dhau thiab quab yuam hloov" uas tuaj yeem ua rau thim rov qab los yog S- zoo li txoj kev taug, ua kom lub borehole du.

2. Strictly implement "measurement every 3 meters of drilling": Promptly detect lateral/longitudinal deviations (>0.3 meters) thiab pib kho kom tiv thaiv kev sib txawv ntawm qhov sib txuam.

3. Tsis txhob tig thaum lub sij hawm kev taw qhia ua ntej: Thaum lub sij hawm hloov kev taw qhia, kev sib hloov me ntsis yuav tsum tau nres, thiab tsuas yog axial thrust yuav tsum tau thov; txwv tsis pub, kev taw qhia yuav ua tsis tiav.

4. Rov qab mus rau qhov chaw ruaj khov ua ntej kev kho: Ua ntej kho, thim rov qab 1 ~ 2 drill rods (3 ~ 6 meters) los xyuas kom meej tias txoj kev tshiab pib los ntawm qhov chaw siv yam tsis muaj offset.

II. Precise Control ntawm Tool Face Angle
Siv cov txheej txheem tswj kev taw qhia kom raug kho cov ntawv qhia phaj rau lub hom phiaj:

12 teev txoj hauj lwm → Upward kho;

6 teev txoj hauj lwm → downward kho;

3 teev tsaus ntuj lossis 9 teev sawv ntxov → Kev kho sab xis lossis sab laug.

Tam sim ntawd kaw lub laum pas nrig tom qab hloov kho kom tsis txhob lub ntsej muag lub ntsej muag sib txawv vim kev sib hloov.

III. Dynamic Adjustment Strategy Raws li Tsim

1. Mos Av Layer: Yooj yim rau "drifting," txo qhov ntsuas qhov ntev mus rau 2 meters, siv siab -frequency fine-tuning, thiab txo cov av nkos kom txo tau cov teebmeem buoyancy.

2. Gravel Layer: Loose particles, nws raug nquahu kom siv bevel laum me ntsis txhawm rau txhim kho cov lus qhia raug, ua ke nrog siab - ntim av nkos twj tso kua mis kom ruaj khov ntawm phab ntsa borehole.

3. Pob Zeb Layer: Cov lus teb qeeb qeeb, ncua lub sijhawm ua ntej kev taw qhia, ntxiv dag zog rau cov av nkos txias, thiab tiv thaiv cov khoom siv overheating ua rau tus cwj pwm tswj tsis tau.

4. Alternating Mos thiab Hard Layers: Cia siab ua ntej, zoo - kho lub ntsej muag lub kaum sab xis kom tso cai rau lub kaum sab xis them nyiaj, thiab zam qhov "head-up/head-down" deviations.

IV. Kev them nyiaj yug Technical thiab Management

1. Kev tiv thaiv- cuam tshuam kev teeb tsa: Thaum tsim los ze rau siab - cov kab hluav taws xob lossis cov qauv hlau, hloov mus rau cov ntsuas hluav taws xob lossis qhib lub tshuab hluav taws xob hauv av kom tsis txhob muaj teeb meem wireless vim muaj kev cuam tshuam sib nqus.

2. Tiag -time Data Comparison: Ntshuam qhov ntsuas trajectory mus rau hauv BIM 3D qauv thiab dynamically muab piv nrog rau txoj kev tsim kom paub tam sim no sib txawv.

3. Cov ntaub ntawv pov thawj thiab pov thawj: Ua kom tiav cov ntaub ntawv qhia txog kev tsim kho cov ntaub ntawv, sau cov thrust, torque, twj tso kua mis siab, thiab cov av nkos tsis haum rau txhua qhov tho yeeb nkab los pab txhawb qhov teeb meem tracing.

4. Kev cob qhia cov neeg ua haujlwm tau zoo: Cov neeg ua haujlwm yuav tsum paub cov qauv kev teb thiab kev kho cov logic, tshem tawm cov haujlwm raws li qhov xav tau.
