Vim li cas CMC tuaj yeem siv rau hauv cov roj drilling?

Carboxymethyl cellulose (CMC) pom kev siv dav hauv cov roj drilling vim nws cov khoom tshwj xeeb uas hais txog ntau qhov kev sib tw hauv cov txheej txheem drilling. Nov yog vim li cas CMC siv hauv roj drilling:

1. Dej viscosity tswj:

Hauv kev lag luam roj drilling, cov kua dej drilling (tseem hu ua cov av nkos) yog qhov tseem ceeb rau lubrication, txias, thiab tshem tawm cov khib nyiab. Cov kua dej no yuav tsum muaj kev tswj cov viscosity kom ua tau zoo nqa cov pob zeb txiav rau saum npoo thiab tswj kev ruaj ntseg hauv lub qhov borehole. CMC ua haujlwm raws li kev hloov kho rheology hauv cov kua dej drilling, tso cai rau cov kws ua haujlwm kom tswj tau cov viscosity thiab ntws ntawm cov av nkos. Los ntawm kev kho qhov concentration ntawm CMC, cov neeg ua haujlwm drilling tuaj yeem kho cov kua dej viscosity kom ua tau raws li cov kev cai tshwj xeeb ntawm kev sib txawv drilling, xws li qhov sib txawv ntawm qhov kub thiab txias.

2. Lim tswj:

Kev tswj cov dej poob lossis pom yog qhov tseem ceeb hauv cov roj drilling los tiv thaiv kev tsim kev puas tsuaj thiab tswj kev ruaj ntseg zoo. CMC ua haujlwm raws li tus neeg saib xyuas kev pom los ntawm kev tsim cov ncuav mog qab zib nyias, impermeable lim rau ntawm phab ntsa borehole. Lub ncuav mog qab zib lim no zoo kaw qhov tsim thiab txo qhov poob ntawm cov kua dej hauv cov pob zeb nyob ib puag ncig, yog li txo qhov tsim kev puas tsuaj thiab khaws cia cov dej ruaj khov. Tsis tas li ntawd, CMC pab txhim kho lub ncuav mog qab zib lim kev ncaj ncees thiab ua haujlwm ntev, ua kom muaj kev ruaj ntseg zoo rau lub sijhawm ntev thaum lub sijhawm ua haujlwm drilling.

3. Ncua tseg ntawm Drilling Cuttings:

Thaum lub sij hawm drilling, pob zeb cuttings yog generated raws li lub laum me ntsis nkag mus rau hauv subsurface formations. Kev ncua zoo ntawm cov cuttings nyob rau hauv cov dej drilling yog qhov tseem ceeb los tiv thaiv lawv qhov chaw thiab sib sau ua ke nyob rau hauv qab ntawm lub borehole, uas tuaj yeem cuam tshuam kev txhim kho drilling thiab ua rau cov khoom puas. CMC ua raws li tus neeg sawv cev ncua, pab kom cov drilling cuttings dispersed thiab tshem tawm hauv cov kua. Qhov no ua kom muaj kev tshem tawm tsis tu ncua ntawm cuttings los ntawm lub qhov dej thiab tswj xyuas qhov zoo tshaj plaws drilling efficiency.

4. Tsim Kev puas tsuaj Mitigation:

Hauv qee qhov xwm txheej ntawm qhov drilling, tshwj xeeb tshaj yog nyob rau hauv kev tsim rhiab heev los yog cov reservoirs, kev siv cov dej drilling tuaj yeem ua rau muaj kev puas tsuaj vim cov dej ntxeem tau thiab kev cuam tshuam nrog cov pob zeb matrix. CMC-raws li drilling kua muaj qhov zoo hauv kev txo qhov tsim kev puas tsuaj, ua tsaug rau lawv kev sib raug zoo nrog ntau hom kev tsim thiab kev sib cuam tshuam tsawg kawg nrog cov kua tsim. Cov khoom uas tsis muaj kev puas tsuaj ntawm CMC pab khaws cia lub reservoir permeability thiab porosity, kom ntseeg tau tias qhov zoo ntawm hydrocarbon ntau lawm tus nqi thiab reservoir kev ua tau zoo.

5. Kev xav txog ib puag ncig thiab kev nyab xeeb:

CMC-based drilling kua feem ntau nyiam rau lawv cov txiaj ntsig ib puag ncig thiab kev nyab xeeb. Piv nrog rau lwm cov additives, CMC yog biodegradable thiab tsis muaj tshuaj lom, txo cov kev cuam tshuam ib puag ncig ntawm kev ua haujlwm drilling thiab txo kev pheej hmoo rau cov neeg ua haujlwm thiab cov tsiaj qus. Tsis tas li ntawd, CMC-raws li cov kua dej muaj tshuaj lom neeg tsawg thiab ua rau muaj kev phom sij tsawg rau cov neeg ua haujlwm drilling, ua rau muaj kev nyab xeeb ua haujlwm hauv cov roj drilling rigs.

Xaus:

Hauv kev xaus, CMC tau siv dav hauv kev ua haujlwm ntawm cov roj drilling vim nws muaj peev xwm los daws ntau yam teeb meem uas tau ntsib hauv cov txheej txheem drilling. Los ntawm kev tswj cov kua dej viscosity thiab pom kom ncua kev txiav cov drilling thiab txo qhov tsim kev puas tsuaj, CMC plays lub luag haujlwm tseem ceeb hauv kev ua kom zoo dua qhov drilling, ua kom muaj kev ruaj ntseg zoo, thiab txo qhov cuam tshuam ib puag ncig. Nws qhov kev ua tau zoo, kev ua tau zoo, thiab kev nyab xeeb ua rau CMC qhov kev nyiam tshaj plaws hauv kev tsim cov kua dej drilling, txhawb nqa kev tshawb nrhiav roj thiab kev tsim khoom lag luam.
