Dab tsi yog qhov sib xyaw ntawm bentonite hauv cov av nkos?

Qhov sib xyaw ntawm bentonite hauv cov av nkos tuaj yeem sib txawv nyob ntawm qhov kev xav tau tshwj xeeb ntawm kev ua haujlwm drilling thiab hom drilling av nkos siv. Bentonite yog ib qho tseem ceeb ntawm cov av nkos drilling, thiab nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho cov viscosity thiab lubrication ntawm cov av nkos. Kev sib xyaw kom zoo yog qhov tseem ceeb rau kev ua kom pom kev zoo drilling av nkos.

Feem ntau, bentonite yog tov nrog dej los tsim ib qho slurry, thiab qhov sib xyaw ua ke yog qhia raws li tus nqi ntawm bentonite (los ntawm qhov hnyav) ntxiv rau ib qho ntim dej. Cov yam ntxwv xav tau ntawm cov av nkos, xws li viscosity, gel lub zog, thiab kev tswj xyuas pom, cuam tshuam rau kev xaiv sib xyaw.

Ntau yam cuam tshuam rau kev txiav txim siab ntawm qhov sib tov sib xyaw, suav nrog hom bentonite siv (sodium bentonite lossis calcium bentonite), drilling tej yam kev mob, thiab cov kev cai tshwj xeeb ntawm kev ua haujlwm drilling. Cov yam tseem ceeb no yuav tsum tau txiav txim siab los kho cov av nkos rau qhov geological yam ntxwv ntawm qhov tsim tau drilled.

Sodium bentonite yog hom bentonite feem ntau siv hauv kev tsim cov av nkos. Ib qho piv txwv sib xyaw rau sodium bentonite av nplaum yog 20 mus rau 35 phaus ntawm bentonite av nplaum ib 100 nkas loos dej. Txawm li cas los xij, qhov piv txwv no tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb drilling thiab tej yam kev mob.

Calcium bentonite, ntawm qhov tod tes, yuav xav tau kev sib xyaw sib txawv piv rau sodium bentonite. Kev xaiv ntawm sodium bentonite thiab calcium bentonite nyob ntawm cov yam ntxwv xws li cov kua dej uas xav tau, salinity ntawm cov dej drilling, thiab cov yam ntxwv ntawm kev tsim.

Ntxiv nrog rau qhov sib xyaw ua ke sib piv, drilling av nkos formulations muaj peev xwm muaj lwm yam additives los txhim kho kev ua tau zoo. Cov additives no yuav muaj xws li polymers, viscosifiers, tshuaj tswj cov kua dej, thiab cov khoom hnyav. Kev sib cuam tshuam ntawm bentonite thiab cov additives no yog ua tib zoo txiav txim siab kom ua tiav cov khoom rheological xav tau thiab cov yam ntxwv ntawm cov av nkos.

Nws yog ib qho tseem ceeb rau cov kws tshaj lij drilling los ua qhov kev sim kuaj thiab kev sim ua kom zoo tshaj qhov sib xyaw ua ke rau kev ua haujlwm tshwj xeeb. Lub hom phiaj yog los tsim cov av nkos uas yuav ua tau zoo nqa cov laum txiav rau saum npoo, muab kev ruaj ntseg rau lub qhov borehole, thiab ua tau raws li ib puag ncig thiab kev tswj hwm ntawm qhov chaw drilling.

Qhov sib xyaw ua ke ntawm bentonite hauv cov av nkos yog qhov tseem ceeb ntawm qhov sib txawv raws li yam xws li bentonite hom, drilling tej yam kev mob thiab xav tau av nkos. Drilling cov kws tshaj lij kev lag luam ua tib zoo tshuaj xyuas cov xwm txheej no los txiav txim siab qhov sib xyaw kom zoo rau kev ua haujlwm tshwj xeeb drilling, kom ntseeg tau tias muaj txiaj ntsig zoo, ua tiav cov txiaj ntsig drilling.
