Cov Kev Siv Tshwj Xeeb ntawm CMC hauv Roj Drilling

CMC (Carboxymethyl cellulose) yog siv dav hauv roj drilling, feem ntau yog nyob rau hauv cov kua dej, ua kua thiab cementing slurries.

1. Daim ntawv thov hauv cov kua dej drilling
Drilling kua yog cov khoom tseem ceeb hauv cov roj drilling txheej txheem, thiab cmc, tuaj yeem txhim kho kev ua tau zoo ntawm cov kua dej. Nws cov haujlwm tshwj xeeb yog raws li hauv qab no:

1.1 Txo cov dej poob
CMC yog cov kua dej txig ua kua uas tuaj yeem tsim cov kua lim thiab tiv thaiv cov dej poob ntawm cov ntoo kom ruaj khov. Qhov no yog qhov tseem ceeb rau kev tiv thaiv kom tsis txhob muaj phab ntsa zoo thiab zam kom tsis txhob muaj kev zam thiab lwm yam teeb meem.

1.2 Txhawb viscosity
CMC tuaj yeem kho cov viscosity ntawm drilling kua, txhim kho lub peev xwm ntawm cov kua dej los nqa cuttings kom nqa cuttings kom nqa cuttings kom thauj cov cuttings kom muaj cuttings, thiab tiv thaiv kom tsis txhob muaj kev txiav tawm, thiab tiv thaiv kev txiavnyog. Ib qho ntxiv, cov viscosity kev hloov kho cov nyhuv ntawm CMC pab txhawm rau txhim kho cov khoom siv tshuab hluav taws xob, ua rau nws haum rau cov chaw lim dej nyuaj.

1.3 Lub DRILLLE DRILLING system
CMC muaj cov ntsev zoo ua tsis zoo thiab kub tsis kam rau cov kua dej drilling. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev ua haujlwm hauv qab high salinity, cov kev tsim cov nyom thiab cov kev mob siab. Nws tuaj yeem tiv thaiv cov kua dej los ntawm kev poob qis thiab ua tsis tau vim muaj electrolyte intrusion.

2. Daim ntawv thov hauv cov kua dej ua tiav
Kev ua tiav kua yog cov kua uas siv los ntxuav qhov chaw nyab xeeb thiab tiv thaiv cov roj thiab roj dej hauv qab tom qab drilling. CMC tseem ua si lub luag haujlwm tseem ceeb hauv kev ua tiav kua dej:

2.1 Tiv thaiv cov roj thiab roj dej muaj txiaj ntsig
CMC tuaj yeem txo cov permeability ntawm kev ua kua dej, tiv thaiv cov roj kom txo cov dej paug, yog li nce roj thiab roj ntau lawm.

2.2 Muab cov kev pab lim lim lim lim
Los ntawm kev sib sau cov khaub ncaws hnav thiab cov lim lim tsawg thiab cov qauv kev puas tsuaj los tiv thaiv kev ua kom ib puag ncig ntawm qhov dej ua tiav.

3. Daim ntawv thov hauv Caasing slurry
Kev cem quav me yog siv los txhim kho cov khoom siv drilling thiab sau lub annulion ntawm qhov chaw nkaum thiab tsim. Qhov sib ntxiv ntawm cmc tuaj yeem ua kom zoo ua kom ua tau zoo ntawm cementing slurry:

3.1 txhim kho rheology
CMC tuaj yeem txhim kho cov khoom siv hluav taws xob ntawm cov cementing slurry, thiab tib lub sij hawm txhim kho kev sib txawv ntawm cov slurrry sau hauv qhov chaw zoo.

3.2 Txhim kho kev tswj hwm dej
Ntxiv CMC rau cov cementing slurry tuaj yeem txo cov dej poob ntawm cov slurry lim thiab cov chaw ua kom zoo nkauj thiab muaj kuab paug los ntawm dej poob.

3.3 Txhim kho slurry ruaj khov
Lub thickening thiab ruaj khov ntawm CMC tuaj yeem tiv thaiv slurry delamination thiab ua kom cov hom phiaj slurry, yog li txhim kho kev ntseeg tau ntawm kev ua haujlwm ntawm kev tso tseg.

4. Lwm txoj haujlwm hauv cov txheej txheem drilling
Ntxiv rau cov ntawv thov tseem ceeb tau hais los saum toj no, CMC tseem tuaj yeem ua lub luag haujlwm txhawb nqa hauv ntau yam ntawm kev nqus roj:

4.1 tiv thaiv corrosion
CMC muaj qee cov tshuaj ruaj khov, tuaj yeem tiv thaiv corrosive Cheebtsam hauv cov kua dej drilling thiab lwm yam ntxiv, thiab cov cuab yeej siv thiab cov khoom siv.

4.2 Txhim kho ib puag ncig ib puag ncig
Raws li cov neeg ua yeeb yam ntuj, CMC muaj cov txiaj ntsig zoo hauv cov roj drilling thiab tuaj yeem txo cov pa phem ib puag ncig ntawm cov kua muaj kua khib nyiab.

4.3 Txo cov nqi
Vim muaj kev ua tiav zoo ntawm CMC, nws tuaj yeem ua tiav cov txiaj ntsig zoo nrog kev siv tsawg dua, yog li nws tuaj yeem txo cov nqi roj txhua yam ntawm cov roj xis.

5. Cov Ntaub Ntawv Raug Cai
Hauv qee qhov kev tsis txaus siab drilling ua haujlwm, xws li cov cua zoo tob, ultra-tob zoo drilling, CMC tau siv dav vim nws qhov kev ua tau zoo heev. Piv txwv li, hauv cov roj ntsha drilling, CMC tuaj yeem txhim kho cov kev ua tau zoo ntawm cov kua dej hauv cov dej khov, kom muaj kev nyab xeeb drilling.

6. Yav Tom Ntej Kev Loj Hlob Kev Qhia ntawm CMC
Nrog kev txhim kho cov roj txuas ntxiv ntawm cov roj drilling thev naus laus zis, kev siv ntawm CMC kuj tseem txuas tas li. Ntawm ib sab tes, drilling cov kua dej additives nrog kev ua tau zoo dua tuaj yeem tsim los ntawm kev sib sau ua ke nrog lwm cov ntaub ntawv polymer; Ntawm qhov tod tes, ua kom zoo dua cov txheej txheem ntau lawm ntawm cmc, txo nws tus nqi thiab kev txhim kho kev tiv thaiv ib puag ncig yuav yog lub hom phiaj ntawm kev tshawb fawb yav tom ntej.

CMC yog siv rau hauv cov roj drilling thoob plaws tag nrho cov dej, ua tiav thiab cov txheej txheem cementing. Nws cov kev ua tau zoo tsis yog txhim kho kev ua haujlwm tau zoo, tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov dej hauv cov dej thiab ib puag ncig. Qhov no ntau yam ntxiv yuav txuas ntxiv mus ua si txoj haujlwm tseem ceeb hauv kev lim dej yav tom ntej.
