Kev ua haujlwm tseem ceeb hauv lub hauv paus rau cov thee mine directional drilling, gas ntws, thiab coalbed methane txoj kev loj hlob, tsis yog - sib nqus laum dab tshos rau cov thee yog kho kom haum rau cov mines 'kev ua haujlwm tshwj xeeb- qhov chaw nqaim, mos coal seams, high humidity, thiab stringent kev nyab xeeb xav tau- thiab ua tiav cov haujlwm hauv qab no:
Ib puag ncig uas tsis yog- ntsuas qhov sib nqus yog tsim nyob rau hauv cov thee mine drilling kom tshem tawm cov kev cuam tshuam sib nqus ntawm cov thee mine-cov cuab yeej tshwj xeeb downhole (piv txwv li, gas concentration sensors, coal seam thickness detectors, thiab trajectory Measuring tools), li no kom ntseeg tau qhov tseeb borehole positioning thiab data dependable coalmition.
Drilling zog yog ruaj khov mus rau lub laum me ntsis; yoog mus rau thee seams 'tsawg- lub zog thiab kev sib tsoo- cov yam ntxwv yooj yim, lawv xa qhov hnyav txaus ntawm me ntsis (WOB) los txhawb kev ua haujlwm drilling, thaum tsis txhob muaj kev vibration ntau dhau uas tuaj yeem ua rau cov pob zeb tawg.
Endowed nrog corrosion kuj, hnav tsis kam, thiab mechanical stability, lawv ua siab ntev thee mine downhole tej yam kev mob (high humidity, thee duster erosion, and moderate pressure), guaranteeing long-term trusted operation in underground thee mine settings.
Ua raws li cov txheej txheem kev nyab xeeb ntawm cov thee mine, lawv cov qauv yog tsim los ua kom haum rau cov thee mine drilling rigs - khav theeb qhov loj me thiab kev sib txuas yooj yim - yog li pab txhawb kev txhim kho thiab kev saib xyuas hauv txoj kev nqaim hauv av.
Peb muaj peev xwm ua tau ntau yam qauv - cov khoom qib thiab muab cov kev pabcuam customized raws li qhov xav tau. Cov ntaub ntawv siv rau qee cov qauv yog raws li hauv qab no:
Cov khoom yog tsim nyob rau hauv tag nrho ua raws li API 7-1 thiab ISO 9001 tus qauv. Nrog rau peb cov cuab yeej kuaj ua tiav, peb tuaj yeem muab cov khoom pov thawj thiab txhawb nqa cov ntaub ntawv xeem.
Tsis yog- cov hlua sib nqus sib nqus rau cov thee yog tsim tshwj xeeb rau kev ua haujlwm ntawm cov thee mine downhole, tsom rau kev tswj roj, kev txhim kho coalbed methane, thiab kev tshawb nrhiav thee mine geological, feem ntau hauv cov haujlwm hauv qab no:
Underground thee mine horizontal directional drilling: Muab ib qho chaw tsis muaj -magnetic ib puag ncig rau cov pa roj borehole positioning instruments, xyuas kom meej qhov chaw ntawm borehole nyob rau hauv siab - gas thee seams thiab txhim kho cov roj extraction efficiency los txo kuv cov pa tawg txaus ntshai.
Ua ntej-draining drilling hauv thee seams: Kho kom haum rau cov mos mos thiab tawg cov thee seams, xa cov zog drilling ruaj khov kom tsis txhob muaj qhov sib tsoo thaum ua kom tsis muaj- sib nqus cuam tshuam ntawm cov roj concentration xyuas cov cuab yeej thaum lub sijhawm drilling.
CBM cov kev taw qhia cov qhov dej: Qhia cov hlua tho kom nkag mus rau cov thee seams kom zoo, nrog rau tsis yog -kev ua haujlwm sib nqus kom ntseeg tau tias qhov ntsuas qhov tseeb ntawm cov roj seam thickness thiab cov ntsiab lus roj, thiab cov qauv kev ruaj ntseg hloov mus rau ntev - lub sij hawm roj ntau lawm drilling cycles.
CBM kev tshawb nrhiav qhov dej: Muab cov ntaub ntawv txhim khu kev qha rau kev ntsuam xyuas cov khoom siv hluav taws xob coalbed methane, zam kev sib nqus qhov sib nqus ntawm cov cuab yeej tshawb nrhiav geological hauv thee-cov kabmob strata.
Coal seam thickness nrhiav kom tau qhov drilling: Koom tes nrog downhole geological logging cuab yeej kom raug ntsuas thee seam thickness thiab tis tsis muaj kev cuam tshuam sib nqus, muab cov ntaub ntawv rau thee mine mining npaj.
Kev kuaj xyuas qhov tsis raug hauv cov mines thee: Laum los ntawm cov chaw ua haujlwm hauv qhov chaw ua txhaum cai, ua kom lub borehole ruaj khov nrog cov qauv ruaj khov thiab ua kom ntseeg tau qhov tseeb qhov kev ntsuas qhov tsis raug nrog tsis- sib nqus ua haujlwm.
Mine txoj kev excavation auxiliary drilling: Pab hauv kev taw qhia drilling rau cov thee mine txoj kev nthuav dav, kom ntseeg tau cov kev raug mob hauv txoj kev nqaim thiab tsis txhob muaj kev cuam tshuam sib nqus ntawm kev saib xyuas kev nyab xeeb hauv av.
Coal mine dej tswj qhov drilling: Ua kom haum rau dej-cov kabmob coal seams, nrog corrosion- cov ntaub ntawv tiv thaiv tiv thaiv xeb hauv siab- qhov chaw noo thiab tsis yog- kev ua haujlwm sib nqus tiv thaiv dej ntsuas ntsuas ntsuas.
Txij li xyoo 2009, SHANXI ZHONGHE tau tshwj xeeb hauv kev txhim kho thiab tsim cov khoom tsis yog-magnetic drilling. Peb tswj hwm tag nrho cov txheej txheem tsim khoom, uas suav nrog kev smelting, forging, thiab machining ntawm cov khoom tsis yog- sib nqus. Nrog rau kev tswj xyuas nruj zoo nyob rau txhua theem, txhua tus neeg cov khoom tau raug tshuaj xyuas zoo thoob plaws hauv cov txheej txheem tsim khoom.Peb nruj me ntsis ua raws li American Petroleum Institute (API) cov qauv thiab feem ntau siv cov ntaub ntawv qib P530, P550, thiab P650 hauv peb cov txheej txheem tsim khoom.
Cim npe nrov: non- sib nqus laum dab tshos rau cov thee, Tuam Tshoj tsis yog- sib nqus laum dab tshos rau cov thee manufacturers, lwm tus neeg, Hoobkas
