Kev Taw Qhia General:

ODEX (luv luv rau "Overburden Drilling Excentric") kuj hu ua Stratex, Tubex lossis ODS. Nws yog kev hloov pauv ntawm huab cua-kho DTH rauj. Nws yog nrog lub viav-tawm eccentric me ntsis kom ream hauv qab ntawm lub casing. Thiab lub percussion me ntsis muaj ob qhov chaw kho cov lus qhia: ib tug concentric tsav me ntsis, thiab tom qab nws yog ib tug eccentric reamer me ntsis uas viav vias tawm mus rau loj lub borehole txoj kab uas hla thaum drilling. Tom qab lub eccentric me ntsis yog ib qho kev qhia ntaus ntawv uas koom ib tug tshwj xeeb sab hauv lub xub pwg nyom casing khau rau hauv qab ntawm lub ODEX casing. Lub ODEX yog li rub los ntawm txoj hlua laum raws li lub qhov tau nce siab. Cuttings tshuab los ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov khoom siv thiab cov khau khiab rau lub voj voog ua rau lawv mus rau hauv av los yog mus rau tus qauv sau.

ODEX systems yog cov kev daws teeb meem kev lag luam feem ntau rau cov casing drilling hauv nruab nrab hauv av. Lawv nrov heev nrog cov neeg ua haujlwm drilling rau cov qhov dej hauv qhov dej, qhov dej kub hauv qhov dej, qhov nruab nrab ntawm qhov nruab nrab ntawm lub tsev, lub pas dej da dej thiab qhov chaw nres nkoj, thiab ntiav micro-piling ua haujlwm. Vim yog lub tis ingenious reaming, lub ntsis yog retrievable thiab siv tau dua. ODEX yog qhov zoo tagnrho rau qhov luv luv hauv homogenous overburden, ua tsaug rau qhov zoo tshaj plaws raws li cov qauv yooj yim, kev ua haujlwm yooj yim, cov cuab yeej drilling rov qab tau, lub neej ua haujlwm ntev thiab zoo. Drilling yam ntxwv ntawm ODEX systems yog qhov tseem ceeb tib yam li rau DTH rauj drilling txoj kev, xws li:

Kev tshem tawm sai ntawm cuttings;

Kev nkag siab siab, tshwj xeeb tshaj yog nyob rau hauv cov pob zeb resistant (xws li basalt);

Ib qho yooj yim av thiab hauv av sampling thaum lub sij hawm drilling;

Muaj peev xwm ntsuas cov txiaj ntsig kwv yees ntawm qhov kev xaiv qhov tob hauv qhov tsim;

Advantageous nyob rau hauv unconsolidated formations uas muaj kev pheej hmoo ntawm caving (qhov no yog tej zaum qhov tseem ceeb tshaj feature).

PLATO muaj ODEX hom xws li ODEX90 txog ODEX280, tsim nrog shanks ntawm feem ntau ntawm DTH hammers sizing ntawm 3 "mus rau 10". Lawv txhua tus muaj xws li Guide Device, Casing Shoe, Eccentric Reamer, Pilot Bit, Guide Tsho, thiab Cov Khoom Siv Xauv.
