To taub Drilling Fluid
Drilling kua, tseem hu ua drilling av nkos, ua hauj lwm raws li ib tug multifunctional tshuaj tseem ceeb rau drilling kev ua hauj lwm nyob rau hauv ntau yam lag luam, xws li roj thiab roj, geothermal, thiab mining.Nws lub hom phiaj tseem ceeb yog los pab hauv qhov drilling boreholes, tswj kev ruaj ntseg zoo, txias thiab lubricating lub laum me ntsis, thauj cov laum txiav rau saum npoo, thiab tiv thaiv kev tsim kev puas tsuaj.Drilling kua yog ib qho sib tov sib xyaw uas muaj ntau yam khoom tsim kom tau raws li cov kev xav tau tshwj xeeb.
Cheebtsam ntawm Drilling Fluid:
Base Fluid: Cov kua hauv paus tsim lub hauv paus ntawm cov dej drilling thiab tuaj yeem yog dej, roj, lossis hluavtaws-raws li, nyob ntawm seb qhov drilling thiab ib puag ncig cov cai.Cov dej-raws li cov kua dej feem ntau yog siv vim lawv cov nqi-zoo thiab ib puag ncig tus phooj ywg.
Additives: Cov khoom siv ntxiv tau muab tso rau hauv cov kua dej drilling los txhim kho nws cov kev ua tau zoo thiab daws cov teeb meem tshwj xeeb uas tau ntsib thaum lub sijhawm drilling.Cov additives muaj xws li viscosifiers, filtration agents, lubricants, shale inhibitors, weighting agents, thiab fluid control agents.
Weighting Materials: Cov khoom hnyav, xws li barite lossis hematite, yog ntxiv los ua kom qhov ntom ntom ntawm cov dej drilling, ua kom nws muaj zog txaus los tiv thaiv kev tsim kev ntxhov siab hauv qhov tob.
Rheology Modifiers: Rheology modifiers tswj cov khoom ntws ntawm cov kua dej drilling, ua kom muaj kev ncua txaus ntawm kev xyaum txiav thiab kev thauj mus los rau saum npoo.Cov kev hloov kho rheology feem ntau suav nrog bentonite, polymers, thiab xanthan gum.
Corrosion Inhibitors: Corrosion inhibitors tau koom ua ke los tiv thaiv cov cuab yeej drilling thiab cov khoom hauv qhov chaw los ntawm cov khoom corrosive tam sim no hauv cov kua tsim.
Biocides: Biocides tiv thaiv kev loj hlob ntawm cov kab mob thiab cov kab mob nyob rau hauv cov dej drilling, txo qhov kev pheej hmoo ntawm microbiologically induced corrosion (MIC) thiab tswj cov kua dej stability.
Sib txawv Drilling Mud los ntawm Drilling Fluid
Thaum drilling av nkos thiab cov dej drilling feem ntau siv sib hloov, qee cov kws tshaj lij kos qhov sib txawv ntawm ob nqe lus raws li lawv cov khoom thiab kev siv.
Drilling av nkos: Raws li kev lig kev cai, drilling av nkos yog hais txog cov roj-raws li drilling kua.Drilling av feem ntau muaj cov kua hauv paus tsim los ntawm cov khoom siv roj av zoo lossis cov roj hluavtaws.Roj-raws li av nkos muaj qhov zoo xws li kev txhim kho lubrication, kev ruaj ntseg ntawm qhov kub thiab txias, thiab txhim khu kev ruaj ntseg zoo hauv qee qhov kev tsim.
Drilling Fluid: Hauv qhov sib piv, cov kua dej drilling suav nrog ntau pawg uas suav nrog cov dej-raws li thiab roj-raws li cov qauv, nrog rau cov khoom siv hluavtaws.Dej-raws li drilling kua, uas yog feem ntau ntawm kev ua haujlwm drilling, feem ntau hu ua cov kua dej drilling.Cov kua dej hauv dej yog nyiam nyob rau hauv ntau qhov xwm txheej drilling vim lawv qhov kev sib raug zoo ib puag ncig, tus nqi qis dua, thiab yooj yim ntawm kev pov tseg.
Cov ntawv thov thiab cov kev sib tw
Daim ntawv thov:
Kev Tshawb Fawb Drilling: Drilling kua ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav kev ua haujlwm drilling, qhov twg lub hom phiaj tseem ceeb yog ntsuas subsurface geology thiab txheeb xyuas cov peev txheej hydrocarbon reservoirs.
Siv tau zoo: thaum tsim kho kom zoo, tho kev pab hauv stidilizing lub condbore, tswj hwm kev teeb tsa ntawm casing thiab xis mas.
Kev Ntsuam Xyuas Kev Tsim Kho: Cov kua dej Drilling pab kom rov qab tau cov qauv tseem ceeb thiab pab txhawb ntau yam kev ntsuas kev tsim, suav nrog kev txiav thiab kev sim.
Kev sib tw:
Kev txhawj xeeb ib puag ncig: Kev pov tseg ntawm cov dej drilling ua rau muaj teeb meem ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv kev lag luam tawm ntug dej hiav txwv uas cov kev cai nruj tswj kev tawm mus rau hauv ib puag ncig marine.
Tsim Kev puas tsuaj: Kev tsim cov dej tsis raug drilling tuaj yeem ua rau muaj kev puas tsuaj, ua rau cov khoom tsim tau zoo thiab lub neej ntev.Kev tswj cov kua dej muaj pes tsawg leeg thiab cov khoom pom yog qhov tseem ceeb los txo qhov kev pheej hmoo no.
Fluid Poob: Cov kua dej poob, los yog cov infiltration ntawm cov dej drilling rau hauv qhov tsim, tuaj yeem ua rau lub cev tsis muaj zog, kev poob qis, thiab txo qhov kev ua haujlwm zoo.Kev sib koom ua ke cov tshuaj tiv thaiv cov dej tsis zoo yog qhov tseem ceeb los daws qhov teeb meem no.
Thaum cov ntsiab lus "drilling av" thiab "drilling fluid" feem ntau siv sib hloov, lawv tuaj yeem xa mus rau cov qauv sib txawv me ntsis thiab kev siv hauv cov ntsiab lus ntawm kev ua haujlwm drilling.Drilling kua ua hauj lwm raws li ntau yam khoom tseem ceeb rau borehole drilling, muab functionalities xws li lubrication, cuttings thauj, thiab wellboe stability.Txawm hais tias dej-raws li, roj-raws li, los yog hluavtaws, muaj pes tsawg leeg ntawm cov dej drilling yog tsim los ua kom tau raws li cov kev sib tw drilling tshwj xeeb thaum ua raws li kev cai ib puag ncig.Los ntawm kev nkag siab txog qhov tsis sib xws ntawm cov dej sib xyaw ua ke thiab tus cwj pwm, cov kws ua haujlwm drilling thiab cov neeg ua haujlwm tuaj yeem ua kom zoo dua qhov kev ua haujlwm drilling thaum txo qhov cuam tshuam ib puag ncig thiab ua kom muaj kev ncaj ncees.
