Cov Yam Cuam Tshuam Rau Qhov Zoo Thiab Qhov Ceev Ntawm Drilling

1. Txij li thaum qhov ceev ntawm qhov kev sib tsoo ntawm cov khoom sib xyaw yog ob npaug ntawm cov iav II ntawm lub tshuab drilling, thiab yuav luag plaub npaug ntawm cov iav I, nws yooj yim kom nce ROP ntau heev.

2. Qhov kev sib hloov ceev ntawm kev sib xyaw ua ke yog qhov tsim nyog rau cov yam ntxwv txiav ntawm PDC ntsis hauv kev tsim shear.

3. Txoj kev mus rau qhov dej yog du. Kev sib xyaw ua ke ntawm kev khawb thiab kev khawb swb rau kev hloov pauv sijhawm, nws yooj yim los tswj lub kaum sab xis ntawm lub qhov thiab xyuas kom muaj kev nyab xeeb ntawm qhov hauv qab.

4. Cov qauv cuab yeej drilling tau yooj yim heev. Thaum lub sijhawm compound drilling, lub siab drilling feem ntau yog <100-120kN, thiab cov kev xav tau drilling tuaj yeem ua tiav nrog tsawg dua lossis tsis muaj lub dab tshos laum, thiab qhov tshwm sim ntawm kev lo rau tau txo qis heev.

5. Lub tshuab laum PDC ua haujlwm tau zoo ua haujlwm nrog lub cuab yeej siv hluav taws xob los laum qhov dej, uas zam kev ua tsis tiav ntawm lub khob hliav qab ntawm kev kub ceev thiab tsis ua rau muaj kev poob ntawm lub khob hliav qab.

Kev Cuam Tshuam ntawm Cov Kev Ntsuas Drilling rau Qhov Ceev Zoo ntawm Drilling

Thaum lub sijhawm ua haujlwm drilling, qhov cuam tshuam ntawm cov kev ntsuas drilling ntawm cov yam ntxwv tswj tau ntawm qhov ceev drilling tsis tuaj yeem tsis quav ntsej, xws li: hom ntsis, lub taub hau nozzle, lub zog dej ntsis, lub zog ntsis, qhov ceev, lub zog twj tso kua mis, kev hloov chaw, thiab lwm yam. Hauv qee qhov xwm txheej, ROP feem ntau yog nce los ntawm kev tswj lub zog drilling, kev sib hloov ceev, lub zog twj tso kua mis thiab kev hloov chaw.

Kev cuam tshuam ntawm Drilling Fluid rau Drilling Quality thiab Speed

Cov kua dej drilling yog cov ntshav ntawm kev drilling, yog li qhov kev ua tau zoo ntawm cov kua dej drilling yog qhov tseem ceeb heev rau kev drilling. Cov yam tseem ceeb uas cuam tshuam rau ROP yog qhov viscosity ntawm cov kua dej drilling, qhov ceev ntawm cov kua dej drilling thiab cov khoom khov hauv cov kua dej drilling. Vim tias tus neeg sawv cev kho mob siv rau hauv cov kua dej tob uas twb muaj lawm yog nplua nuj nyob rau hauv chromium ions thiab lwm yam hlau ions hnyav uas muaj kev cuam tshuam loj rau ib puag ncig, nws raug pom zoo kom kawm thiab siv cov kua dej drilling uas zoo rau ib puag ncig los txhim kho cov kua dej drilling silicate uas tam sim no siv hauv ntau qhov me me hauv Suav teb, Synthetic basic drilling system los tsim cov kua dej drilling uas tiv thaiv ib puag ncig uas haum rau cov xwm txheej geological thiab engineering ntawm txhua qhov chaw drilling.
