Cultivating the Land of Egypt: Txoj kev mus rau kev vam meej hauv av Exploration Project

Tsis ntev los no, peb cov neeg siv khoom tau ua tiav txoj haujlwm tshawb nrhiav av hauv tebchaws Egypt thiab xa peb cov vis dis aus qhia txog lawv cov txheej txheem tshawb nrhiav av siv qhov tseeb.tri-cone laum khoom.

Cov duab onsite tso saib cov neeg siv khoom siv drilling thiab kev ua haujlwm zoo, nrog raulaum khoomtsis tu ncua nkag mus rau hauv av raws li cov neeg ua haujlwm saib xyuas txhua kauj ruam. Qhov kev ua tau zoo ntawm tri-cone laum cov khoom tau ua rau kev tshawb nrhiav cov txheej txheem nrawm thiab txhim khu kev qha, ua rau tus neeg siv khoom taug qab ntau yam teeb meem hauv cov txheej txheem geological nyuaj nrog yooj yim.

Qhov kev sim no tsis tau tsuas yog ntxiv dag zog rau peb txoj kev koom tes nrog cov neeg siv khoom tab sis kuj tau ua tus qauv zoo rau lwm lub tuam txhab hauv kev lag luam, ua kom pom qhov tseem ceeb ntawm cov cuab yeej tshaj lij thiab cov thev naus laus zis hauv kev tshawb nrhiav av. Peb tau cog lus tias yuav muab cov khoom lag luam zoo thiab cov kev pabcuam zoo los txhawb peb cov neeg siv khoom zoo hauv txhua qhov kev ua haujlwm.

 Kev siv ntawmTri-Cone Drill Bits

1. Kev cuam tshuam ntawm txawv Geological Formations rauDrill BitUa tsis tiav

Kev cuam tshuam ntawm geological formations ntawm laum me ntsis tsis ua hauj lwm feem ntau manifests nyob rau hauv cov txheej txheem drilling, cuam tshuam rau drilling ceev thiab nkag mus rau tus nqi thaum uas yuav ua rau muaj teeb meem xws li poob zoo, blowouts, collapses, thiab me ntsis jamming. Kev hloov ntawm cov av nkos kuj tuaj yeem cuam tshuam qhov zoo ntawm qhov zoo, nrog rau kev sib txawv ntawm qhov zoo thiab qhov tsis sib xws, tom qab ntawd cuam tshuam rau cementing zoo. Los ntawm kev tshuaj xyuas geological formations thiab lawv cov teebmeem ntawm cov txheej txheem drilling, peb tuaj yeem txiav txim siab paub txog kev xaiv thiab kev siv laum.

• Av nplaum, Mudstone, thiab Shale: Cov qauv no zoo li nqus dej dawb los ntawm cov av nkos drilling, ua rau o, txo txoj kab uas hla ntawm qhov dej, thiab muaj peev xwm drilling hindrances, nrog rau me ntsis jamming. Nyob rau lub sij hawm ntev soaking, thaiv detachment tej zaum yuav tshwm sim, ua rau wellbore expansion thiab vau. Yog li ntawd, nws raug nquahu kom siv cov dej huv lossis qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Carbonaceous shale muaj kev sib koom ua ke tsis muaj zog, ua rau nws yooj yim tawg, thaum cov av nkos tsim, ua softer, tso cai rau kev drilling sai dua tab sis muaj kev cuam tshuam rau cov av nkos.

• Sandstone: Cov yam ntxwv ntawm cov xuab zeb sib txawv raws li qhov loj me, muaj pes tsawg leeg, thiab cov khoom siv cementing. Cov khoom me me, cov ntsiab lus ntau dua quartz, thiab nce silica thiab hlau cement yields harder formations, ua rau hnav ntau dua ntawm cov laum khoom; conversely, ntau av nplaum-raws li cement ua rau softer thiab yooj yim drilled formations. Coarser particles nrog tsawg cement tuaj yeem ua rau cov av nkos tsis tau, ua rau cov av nkos tuab ntawm qhov dej thiab cov teeb meem jamming.

• Gravel: Drilling nyob rau hauv gravel formations tau yooj yim ua rau dhia khoom, khi, thiab lub qhov dej puas. Thaum lub twj tso kua mis qis los yog cov av nkos tsis txaus, cov gravel particles yuav tsis rov qab tau yooj yim, ua rau muaj kev puas tsuaj loj rau cov menyuam lub cev thiab cov hniav.

• Limestone: Feem ntau nyuaj thiab qeeb rau kev xyaum, limestone tuaj yeem nthuav tawm qis nkag mus. Qee qhov chaw yuav muaj qhov tsis muaj dab tsi, thiab kev khawb rau hauv cov kab noj hniav no tuaj yeem ua rau muaj kev sib khi, ploj mus, thiab ua kom tawg tom qab av nkos.

Limestone formations ho cuam tshuam tus nqi nkag, mechanical drilling ceev, thiab xyaum me ntsis tsis ua hauj lwm. Tsis tas li ntawd, thaum softer thiab harder formations interlace, xws li av nkos alternating nrog nyuaj sandstone, zoo deviation yog ntau dua; cov kaum sab xis hauv cov formations kuj tuaj yeem ua rau muaj kev cuam tshuam zoo. Drilling ntawm cov ces kaum tuaj yeem ua rau muaj kev pheej hmoo ntawm kev puas tsuaj me ntsis. Yog tias qhov tsim muaj cov ntsev ntsev (xws li gypsum lossis pob zeb ntsev txheej), cov khoom ntawm cov av nkos yuav raug cuam tshuam, cuam tshuam rau kev ua haujlwm ib txwm ntawm cov khoom siv laum.
