Yuav ua li cas kho qhov sib txawv thaum lub sij hawm kab rov tav Directional Drilling
May 08, 2026| I. Cov Ntsiab Cai ntawm Kev Deviation Kho
1. Kev Tshawb Nrhiav Thaum Ntxov thiab Kho: Cov ntaub ntawv taug qab yuav tsum tau ntsuas txhua 3 meters ntawm qhov drilling. Yog hais tias ib tug lateral los yog longitudinal sib txawv tshaj 0.3 meters, tus txheej txheem deviation kho yuav tsum pib tam sim ntawd.
2. Zoo-tuning raws li txoj hauv kev tseem ceeb: Lub kaum sab xis hloov pauv hauv ib qho kev kho yuav tsum tswj tsis pub dhau 2% ~ 4% kom tsis txhob muaj kev kho loj uas tuaj yeem ua rau rov qab sib txawv lossis qhov tsis sib xws.
3. Kev Kho Nruam Nruam: Siv "ntau qhov kev hloov me me" es tsis yog "ib- lub sijhawm kho kom muaj zog" kom ntseeg tau tias muaj kev hloov pauv ntawm lub ntuj thiab txo qis kev thim rov qab tom qab.
II. Cov txheej txheem kev ua haujlwm ntawm kev sib txawv tshwj xeeb
1. Pullback mus rau ib qho chaw ruaj khov: rub lub laum pas nrig rov qab mus rau qhov chaw uas lub trajectory tsis deviated loj, feem ntau 1 ~ 2 laum pas nrig ntev (kwv yees li 3 ~ 6 meters). Xyuas kom meej tias qhov seem ntawm cov qauv borehole no zoo li qub thiab tsis muaj kev cuam tshuam, ua qhov pib siv rau qhov tshiab trajectory.
2. Txiav txim siab lub ntsej muag ntawm lub cuab yeej. Raws li cov cuab yeej lub ntsej muag lub kaum sab xis tso tawm los ntawm cov txheej txheem kev taw qhia, txiav txim siab qhov kev xyaum me ntsis tam sim no. Rau kev kho downward, kho lub ntsej muag lub ntsej muag rau 6 teev; rau kev kho siab, kho rau 12 teev; rau sab laug lossis txoj cai kho, kho rau 9 teev lossis 3 teev sawv ntxov, raws li.
3. Siv cov kev taw qhia drilling. Tsis txhob xyaum me ntsis kev sib hloov thiab siv tsuas yog axial thrust, ua rau lub laum me ntsis "rub" los yog "rub" raws li cov kev taw qhia tsis muaj kev sib hloov. Qhov ntev ua ntej yog feem ntau 2-3 npaug ntawm qhov xyaum me ntsis ntev los ua ib txoj hauv kev ruaj khov tshiab.
4. Rov ua dua thiab txheeb xyuas qhov kev sib tw. Tom qab paub meej tias lub laum me ntsis tau nkag mus rau qhov kev taw qhia tshiab, rov pib tig qhov drilling. Tshawb xyuas cov ntaub ntawv azimuth thiab lub kaum sab xis txhua 1-2 meters kom paub meej tias kev kho tau zoo thiab tsis muaj kev hloov kho ntau dhau.
5. Cov av nkos sib xyaw thiab tswj
Nyob rau hauv cov av mos, tsim nyog txo cov av nkos viscosity los tiv thaiv kev xyaum me ntsis drift vim ntau buoyancy.
Nyob rau hauv cov pob zeb tawv txheej, txhim kho av nkos txias thiab lubrication kev ua tau zoo kom txo tau qhov cuam tshuam ntawm kev sib txhuam ntawm cov cua sov ntawm kev xyaum me ntsis thiab txhim kho kev kho kom zoo.
III. Kho cov tswv yim rau kev sib txawv
1. Mos Av Layers: Cov av tsis tshua muaj peev xwm ua rau cov laum me ntsis yooj yim rau drift. Ua kom ntsuas qhov zaus thiab siv siab -frequency fine-tuning los tswj cov trajectory.
2. Gravel Layers: Cov khoom xoob xoob thiab kev ruaj ntseg tsis zoo ua rau lub laum me ntsis. Nws raug nquahu kom siv cov kev taw qhia siab inclined laum me ntsis ua ke nrog lub siab -cov lus qhia qhov tseeb.
3. Hloov Cov Khoom Muag thiab Cov Txheej Txheem Nyuaj: Cov kev ntxhov siab tsis sib xws tuaj yeem ua rau "lub taub hau- nce" lossis "lub taub hau- nqis" phenomena. Txo qhov drilling ceev thiab dynamically kho lub ntsej muag lub kaum sab xis kom ruaj khov drilling.
4. Pob zeb Formations: Kev ua haujlwm siab drilling thiab kho qeeb qeeb yuav tsum tau txuas ntxiv lub sijhawm drilling thiab txhim kho av nkos kom tiv thaiv cov khoom siv overheating.
IV. Tshwj xeeb ib puag ncig Auxiliary Technologies
1. In areas with high-voltage lines and dense metal structures, wired sensors are used to transmit data, avoiding distortion of wireless signals due to electromagnetic interference.
2. Lub tshuab hluav taws xob hauv av yog siv los tsim cov khoom siv hluav taws xob sib nqus rau tiag tiag - lub sijhawm ntsuas qhov ntsuas qhov ntsuas, txhim kho qhov tseeb ntawm qhov chaw nyob hauv ib puag ncig nyuaj.
3. Rau ultra-ntev deb los yog txoj haujlwm nyuaj heev, ob txoj kev drilling nrog nruab nrab docking thev naus laus zis tuaj yeem siv, drilling ib txhij los ntawm ob qho kawg thiab sib sau ua ke ntawm ib qho kev txiav txim siab, txo qhov siab ntawm kev kho unilateral.
