Tej yam cuam tshuam rau Drilling zoo thiab ceev

1. Txij li thaum lub laum me ntsis ceev ntawm compound drilling yog ob zaug ntawm iav II ntawm qhov drilling rig, thiab ze li plaub zaug ntawm iav kuv, nws yog ib qho yooj yim kom nce ROP.

2.Qhov kev sib hloov ceev ceev ntawm kev sib txuas drilling yog tsim rau kev txiav cov yam ntxwv ntawm PDC me ntsis hauv kev tsim shear.

3.Wellbore trajectory yog du. Ua ke cov kev taw qhia drilling thiab zawv zawg qhov drilling rau lub sijhawm hloov pauv, nws yooj yim los tswj lub kaum sab xis dogleg thiab xyuas kom muaj kev nyab xeeb ntawm qhov chaw.

4.Cov cuab yeej drilling yog qhov yooj yim. Thaum lub sij hawm sib xyaw ua ke, qhov drilling siab feem ntau yog <100-120kN, thiab cov kev xav tau ntawm qhov drilling tuaj yeem ua tiav nrog tsawg dua los yog tsis muaj dab tshos tho, thiab qhov ua tau zoo yog txo qis heev.

5. Lub tshuab ua haujlwm siab PDC laum me ntsis koom tes nrog lub zog drilling cuab yeej los laum qhov dej, uas zam qhov tsis ua hauj lwm thaum ntxov ntawm lub khob hliav qab ntawm kev kub ceev thiab tsis ua rau lub khob poob siab.

Influence of Drilling Parameters on Drilling Quality Speed

Thaum lub sij hawm drilling txheej txheem, cov kev cuam tshuam ntawm cov kev tsis sib txawv ntawm cov kev tswj ntawm qhov drilling ceev yuav tsis raug ignored, xws li: me ntsis hom, me ntsis nozzle txoj kab uas hla, me ntsis dej hwj chim, me ntsis siab, ceev, twj tso kua mis siab, displacement, thiab lwm yam. Cov ntaub ntawv ntawm qee lub hom phiaj xwm txheej, ROP feem ntau yog nce los ntawm kev tswj cov drilling siab, kev sib hloov ceev, twj tso kua mis siab thiab hloov chaw.

Influence of Drilling Fluid on Drilling Quality and Speed

Drilling kua yog cov ntshav ntawm drilling, yog li qhov kev ua tau zoo ntawm cov dej drilling yog qhov tseem ceeb heev rau kev drilling. Lub ntsiab tseem ceeb cuam tshuam rau ROP yog qhov viscosity ntawm cov kua dej drilling, qhov ceev ntawm cov kua dej drilling thiab cov ntsiab lus ntawm cov dej drilling. Nyob rau hauv kev pom ntawm qhov tseeb hais tias tus neeg saib xyuas kev kho mob siv nyob rau hauv lub uas twb muaj lawm lub qhov dej tob system yog nplua nuj nyob rau hauv chromium ions thiab lwm yam hnyav hlau ions uas muaj kev cuam tshuam zoo rau ib puag ncig, nws raug nquahu kom kawm thiab siv ib puag ncig tus phooj ywg tob tob drilling kua. system los txhim kho lub silicate drilling kua system tam sim no siv nyob rau hauv ib tug me me ntau yam nyob rau hauv Tuam Tshoj, Synthetic yooj yim drilling system los tsim ib tug sib sib zog nqus zoo ib puag ncig tiv thaiv drilling kua series haum rau geological thiab engineering tej yam kev mob ntawm txhua qhov chaw drilling.
