Raws li cov cuab yeej downhole rau thee mine directional drilling, roj cia, thiab CBM ntau lawm, tsis yog -stabilizers magnetic stabilizers rau thee yog tsim los rau thee mines 'kev ua hauj lwm tej yam kev mob (txoj kev nqaim, mos / tawg coal seams, high humidity, thee plua plav, thiab kev nyab xeeb yuav tsum tau ua) thiab ua cov hauj lwm nram qab no: Hauv coal mine drilling, tsis muaj kev ntsuas tshwj xeeb los ntawm{1} cheeb tsam sib nqus. cov cuab yeej downhole nrog rau cov roj concentration sensors, thee seam trajectory detectors, thiab geological logging cuab yeej, kom tso cai rau qhov tseeb borehole tso thiab txhim khu kev qha cov ntaub ntawv ntawm cov thee seam. Cov khoom no yog ua ke nrog cov phab ntsa borehole, thiab stabilize lub laum txoj hlua nyob rau hauv mos los yog tawg coal seams los ntawm minimizing laum hlua vibration, eccentricity, thiab wobble, uas tiv thaiv borehole vau thiab txhim kho wellbore zoo.Cov no yog heev sib sib zog nqus thiab tso cai rau kom yooj yim kev koom ua ke nrog mine drilling rigs thiab nyob rau hauv qhov chaw nqaim heev. (high humidity, plua plav abrasion, nruab nrab siab), corrosion resistance, hniav hnav tsis kam, thiab mechanical stability, muab kev ua haujlwm ntev -lub sij hawm txhim khu kev qha yam tsis muaj kev cuam tshuam kev nyab xeeb.
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.
Tsim tshwj xeeb rau kev lag luam thee mine downhole, tsis yog -stabilizers magnetic stabilizers rau thee tsom rau kev tswj roj, kev txhim kho coalbed methane, thiab thee mine geological tshawb nrhiav, nrog rau thawj daim ntawv thov thoob plaws hauv qab no:
Hauv av kab rov tav kev taw qhia cov roj ntws tawm: Lawv ua kom ruaj khov rau txoj hlua tho hauv cov mos siab siab - pa roj carbon seams, tiv thaiv cov borehole vau thiab xyuas kom meej qhov chaw ntawm cov roj ntws tawm. Lawv qhov tsis yog -magnetic traits precludes cuam tshuam nrog roj concentration sensors thiab trajectory ntsuas cov cuab yeej, boosting gas extraction efficiency thiab mitigating mine explosion txaus ntshai.
Ua ntej- mining gas pre-drainage drilling: Acclimating rau fractured thee seams, lawv dampen laum hlua vibration kom tsis txhob exacerbating thee seam fractures, yog li khaws cia cov kev ncaj ncees ntawm cov roj ntws boreholes.
CBM cov kev taw qhia cov qhov dej: Qhia txoj hlua tho kom nkag mus rau cov thee seams kom zoo, cov hniav sib txuas tsis sib haum borehole deformation hauv cov coal seams. Tsis yog- kev ua tau zoo sib nqus ua rau muaj qhov ntsuas qhov tseeb ntawm cov roj seam tuab thiab cov ntsiab lus roj, ua kom yooj yim rau kev tshem tawm CBM.
CBM kev tshawb nrhiav qhov dej: Txhim khu kev ruaj ntseg yog npaj rau geological logging cov cuab yeej, tsis txhob sib nqus teb distortion ntawm subsurface cov ntaub ntawv thiab xyuas kom meej kev ntsuam xyuas ntawm CBM peev xwm.
Coal seam thickness thiab faib nrhiav kom tau: Hauv kev koom tes nrog downhole geological instruments, lawv pab kom raug ntsuas ntawm thee seam thickness dawb los ntawm kev sib nqus cuam tshuam, muab cov ntaub ntawv txhawb nqa rau kev npaj mining thee.
Coal mine fault thiab dej-kev tshawb nrhiav cov qauv kabmob: Hauv qhov chaw txhaum lossis dej-cov kabmob thee, lawv ruaj khov rau txoj hlua tho kom muaj kev ruaj ntseg hauv lub qhov dej, thaum ua kom tsis muaj kev cuam tshuam ntawm qhov chaw txhaum thiab dej ntsuas ntsuas ntsuas.
Mine txoj kev nthuav dav kev taw qhia drilling: Boasting ib tug compact qauv, lawv hloov mus rau hauv av nqaim txoj kev, coj txoj hlua laum raws tus tsim trajectory thiab tsis txhob sib tsoo nrog ib puag ncig cov pob zeb. Hnav- cov hniav tiv taus tiv taus cov pa roj av yaig, ua rau lub neej ua haujlwm ntev hauv qhov chaw muaj plua plav.
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-magnetic stabilizers rau thee, Tuam Tshoj tsis yog-magnetic stabilizers rau thee manufacturers, lwm tus neeg, Hoobkas
