Cov txheej txheem rau kev kho lub kaum sab xis ntawm kab rov tav Directional Drilling Rig

I. Cov txheej txheem ua haujlwm tseem ceeb

1. Cia siab tias tsim muaj kev cuam tshuam: Ua ntej nkag mus rau cov txheej txheem ntawm cov pob zeb mos thiab tawv tawv lossis pebble txheej, zoo - kho lub ntsej muag lub ntsej muag raws li daim ntawv tshaj tawm geological, tseg lub kaum sab xis them nyiaj los tiv thaiv lub laum me ntsis los ntawm "txoj hauv ntej" lossis "txoj hauv qab."

2. Tswj kev nce qib: Ua kom muaj kev sib tw ceev thaum lub sij hawm kev taw qhia kom tsis txhob muaj kev sib txawv ntau dhau los ntawm kev sib tw tam sim ntawd; tswj txhua qhov kev taw qhia ua ntej ntu mus rau 1.5-3 meters kom ntseeg tau tias muaj kev ruaj khov ntawm txoj kev tshiab.

3. Precise Tool Face Angle Positioning: Siv cov kev taw qhia kev tswj xyuas kom haum cov phaj qhia nrog lub hom phiaj kev taw qhia (piv txwv li, 12 teev sawv ntxov, 6 teev tsaus ntuj), thiab xauv lub laum pas nrig tom qab kho kom tsis txhob muaj kev sib hloov.

4. "Retraction Verification" kom paub meej qhov ntsuas ntsuas: Ua ntej kho, thim rov qab 1-2 laum rods mus rau qhov chaw ruaj khov kom paub meej tias qhov qub trajectory tsis tau drifted ua ntej siv kev hloov kho kom tsis txhob yuam kev.

II. Kev hloov cov tswv yim rau kev ua haujlwm sib txawv

1. Mos Av Layer: Yooj yim rau "drift," yuav tsum tau ntsuas luv luv rau 2 meters. Siab -frequency fine-tuning yuav tsum tau ua hauj lwm, nrog rau lub ntsej muag lub kaum sab xis hloov kho nyob rau hauv 2%.

2. Gravel Layer: Cov khoom xoob xoob ua rau lub laum me ntsis slippage. Nws raug nquahu kom siv lub taub hau beveled los txhim kho cov lus qhia raug, nrog rau siab - ntim cov av nkos kom ruaj khov ntawm phab ntsa borehole.

3. Pob zeb txheej: siab drilling tsis kam thiab qeeb teb. Lub sij hawm taw qhia ua ntej yuav tsum tau ncua, thiab cov av nkos txias yuav tsum tau ntxiv dag zog los tiv thaiv overheating thiab poob ntawm tus cwj pwm tswj.

4. Ntev-Kev hla kev deb: Siv ob txoj kev drilling nrog nruab nrab docking tshuab, drilling synchronously los ntawm ob qho kawg. Kev sib piv kev sib piv yog ua nyob rau ntawm qhov sib koom ua ke, txo qhov siab ntawm unilateral kho.

III. Kev Pabcuam Technology los txhim kho qhov tseeb

1. In areas with high-voltage lines and dense metal structures, use wired sensors to transmit data, avoiding distortion of wireless signals due to electromagnetic interference.

2. Siv lub tshuab hluav taws xob hauv av rau cov khoom siv hluav taws xob sib nqus calibration, txhim kho qhov chaw muaj kev ntseeg siab hauv cov cheeb tsam nyuaj.

3. Siv BIM 3D qauv los simulate txoj kev drilling thiab ua ntej - npaj lub ntsej muag lub kaum sab xis rau cov ntsiab lus tseem ceeb kom ua tiav "kev tsim kho raws li daim duab."

IV. Cov Lus Qhia Txog Kev Ua Haujlwm
1. Ntsuas txhua 3 meters ntawm qhov drilling; Yog tias pom qhov sib txawv> 0.3 meters, pib kho tam sim.
2. Tswj qhov kev hloov ntawm lub kaum sab xis rau txhua qhov kev kho tsis pub dhau 2% ~ 4% kom tsis txhob "kho thiab hloov kho sai" uas tuaj yeem ua rau rov qab sib txawv.
3. Tom qab rov pib dua, tsis tu ncua saib xyuas rau 1 ~ 2 meters kom paub meej txog kev ruaj ntseg ua ntej txuas ntxiv cov pa drilling.
