MWD Directional Drill Pipe yog dab tsi
MWD laum yeeb nkab yog siv rau kev taw qhia kab rov tav drilling hauv thee mine tunnels. Thaum siv nrog cov khoom siv hauv orifice, lawv tso saib cov ntaub ntawv drilling trajectory nyob rau lub sijhawm, tso cai rau cov neeg ua haujlwm kho qhov drilling trajectory sai raws li cov ntaub ntawv tso tawm, yog li ua tiav lub hom phiaj ntawm kev taw qhia drilling. Lawv tau siv dav hauv kev tswj xyuas kev tswj xyuas hauv geology, thee, roj av, thiab kev txuag dej kev lag luam.
Khoom nta
Lub laum yeeb nkab lub cev yog welded los ntawm kev sib txhuam vuam txheej txheem, muab cov khoom zoo tag nrho thiab lub neej ua haujlwm ntev. Lub laum yeeb nkab sib txuas xov muaj lub zog siab thiab zoo tiv thaiv -galling kev ua tau zoo. Lub laum yeeb nkab yog tsim los nrog lub teeb liab kis tau tus mob uas ua tiav bidirectional tiag -lub sij hawm kev sib txuas lus ntawm lub downhole ntsuas sojntsuam thiab lub orifice explosion- pov thawj computer, nrog high kis tau tus mob efficiency. Internal conduit thiab pob qij txha muaj zoo sealing kev ua tau zoo thiab siab stability.
Scope ntawm daim ntawv thov
MWD laum kav dej feem ntau yuav tsum tau ua nyob rau hauv cov thee coefficient ntawm 1 los yog ntau tshaj los yog ruaj khov formations mus txog rau ib tug ruaj khov coefficient ntawm 6. Lawv feem ntau yog siv rau kev tsim kho ntawm qhov ntev -ntaus roj qhov dej thiab kev tshawb nrhiav dej thiab cov qhov dej hauv cov pob zeb hauv av rau cov mines, thiab cov kev taw qhia kuj tseem siv tau. nyob ze - kab rov tav engineering qhov.
Kev Tiv Thaiv Kev Ua Haujlwm
Ua ntej siv lub laum yeeb nkab, xyuas seb cov yas sib koom puas muaj xoob, deformation, los yog tawg, xyuas kom meej lub nplhaib sealing zoo, cov xov yog huv si, thiab lub caij nplooj ntoos hlav reducer txhim khu kev qha. Ua ntej ntxiv cov yeeb nkab laum, siv cov xov sib txuas rau cov xov xov thiab cov roj tshwj xeeb rau lub nplhaib sib khi, thiab tswj ua kom - nce ceev mus rau 25 r / min lossis tsawg dua. Ua kom lub qhov drilling trajectory du nrog lub qhov inclination dabtsi yog khoov tswj ntawm 3 degrees ib 6 m thiab azimuth dabtsi yog khoov ntawm 2 degrees ib 6 m. Thaum disconnecting, tswj breakout ceev mus rau 25 r / min los yog tsawg dua thiab xyuas kom meej lub hwj chim lub taub hau retraction nrug yog 100 mm los yog ntau tshaj. Tom qab disconnection, ntws dej los ntawm cov yeeb nkab lub cev thiab haum cov xov tiv thaiv tam sim ntawd.
Technical Parameters
A 75 hli specification muaj ib tug pas nrig lub cev OD ntawm 73 hli, sib koom ua ke OD ntawm 75 hli, ntev ntawm 3000 hli, siab tsis kam ntawm 10 MPa, conductor kuj qis dua 0.5 ohm, rwb thaiv tsev tsis kam siab tshaj 2 megohm, pom zoo drilling torque ntawm 6000 N m, thiab nyiam me ntsis loj ntawm 96 hli. Lub 89 hli specification muaj ib tug pas nrig OD ntawm 89 hli, sib koom OD ntawm 91 hli, pom zoo torque ntawm 12000 N m, thiab nyiam me ntsis ntawm 113 hli.
