Rov qab Circulation Laum Pipe

Nyob rau hauv cov nqe lus ntawm ob qho tib si tus nqi thiab zoo, peb Reverse Circulation Laum Pipe outperforms piv cov khoom nyob rau hauv lub lag luam. LEANOMS Reverse Circulation Laum Pipes kuj tseem muaj zog heev, vim yog siv cov khoom zoo thoob plaws hauv cov txheej txheem tsim khoom. Yuav luag tag nrho peb cov kev muag khoom yog rau cov neeg ua haujlwm drilling, uas tau qhib siab qhia peb Reverse Circulation Laum Pipe txij li lawv siv sijhawm ntev dua thiab xyaum sib sib zog nqus nrog tib huab cua, muab cov txiaj ntsig zoo tshaj plaws rau cov nyiaj. Tsis tas li ntawd, peb qhov rov qab rov qab laum pas nrig tau tsim tshwj xeeb rau RC drilling thiab muaj nyob rau hauv txoj hlua rov qab rov qab drilling hlua ua ke hauv qab no.

Thaum tab tom nrhiav ore deposits los txhim kho, qhov chaw tshawb nrhiav pob zeb siv RCqhov drillingkom tau txais cov qauv neeg sawv cev ntawm tus nqi qis. Txoj kev thim rov qab yog feem ntau siv rau hauv cov tawv tawv, tawg, thiab abrasive formations. Hauv qee qhov xwm txheej, txoj hauv kev no muaj ntau tus nqi txiaj ntsig tshaj pob zeb diamond coring.

Qhov zoo ntawm Reverse Circulation Drilling

Txhim khu kev qha thiab tsis muaj kab mob:

Kev sib kis kab mob yog zam vim qhov kev txiav tsis nkag mus rau lwm qhov ntawm lub qhov thaum nws txav mus los ntawm qhov me me thiab mus rau hauv cov raj sab hauv rau hauv cov cua daj cua dub. Raws li qhov tshwm sim, nws tuaj yeem ua tau los tsim kom muaj ntau qhov kev ntseeg siab, cov qauv zoo.

Cuttings los ntawm cov qauv yog yooj yim rau catalog thiab khaws cia. Cov neeg soj ntsuam thiab lwm tus neeg txaus siab yuav tuaj yeem tshawb pom cov peev txheej ntxhia ntau dua vim tias cov qauv sib sau ua ke yuav muaj qhov tshwj xeeb ntawm txoj haujlwm thiab qhov tob uas lawv nyob.

High drilling nkag tus nqi:

Nyob rau hauv qhov tob loj dua, Rov qab Circulation Drill Pipe tus nqi feem ntau nrawm dua thiab sib npaug rau qhov qhib qhov drilling. Lub raj sab hauv cov qauv tshaj tawm tuaj yeem ncav cuag tus nqi ntawm 250 m / sec, tso cai kom rov qab tau cov tho kev txiav cov txheej txheem ceev thiab nyab xeeb uas yuav tsum tau ua haujlwm tsawg dua.

Cov nqi ntau lawm yog siab dua cov pob zeb diamond drilling; ntawm qhov ceev tshaj 10 m / h, tus nqi ntawm 200-300 m / hnub yog ntau. Yog li ntawd, RC drilling cov ntaub ntawv yuav raug nthuav tawm rau cov neeg siv khoom nrawm dua vim tias cov txheej txheem drilling tau nrawm dua.

Ntau yam nyob rau hauv ib puag ncig nyuaj:

Rov qab Circulation Laum Pipe yog qhov yooj yim heev thiab siv dej tsawg dua li pob zeb diamond drilling, ua rau nws zoo heev hauv cov teb chaws xws li Australia uas cov dej yuav kim lossis txwv. Rov qab Circulation Drilling kuj tseem pheej yig dua li pob zeb diamond drilling, nrog rau cov nqi khiav lag luam nce mus txog 40 feem pua.

Kev txuag nqi yog qhov pom tseeb tshaj plaws hauv thaj chaw geologically complex, qhov twg ntau cov txheej txheem drilling yuav ua rau tus nqi ntau dua. Txij li Reverse Circulation Drilling yog qhov ruaj khov dua hauv cov xwm txheej nyuaj, cov kev siv nyiaj yuav raug khaws cia kom tsawg.
