Ua rau thiab kev daws teeb meem rau qhov nyuaj Disassembling Laum Pipe ntawm Kab rov tav Directional Laum

Nyob rau hauv tus txheej txheem ntawm backdragging thiab reaming ntawm Kab rov tav Directional Drill,nws feem ntau tshwm sim hais tias lub laum yeeb nkab yog qhov nyuaj rau disassemble, uas ua rau lub sij hawm ncua ntawm kev tsim kho.Yog li dab tsi yog qhov ua rau thiab kev daws teeb meem rau qhov nyuaj disassembly ntawm laum yeeb nkab?

Ua rau:

Drilling yeeb nkab drilling lub kaum sab xis sib txawv

In lub sijhawm npaj, tus neeg teb xov tooj tsis tuaj yeem kho lub kaum sab xis ntawm lub laum thav duab hauv lub sijhawm thiab raug, uas ua rau qhov sib txawv ntawm lub kaum sab xis ntawm qhov nkag ntawm lub cev ntawm lub laum rig thiab lub laum yeeb nkab, uas ua rau qhov sib txawv ntawm qhov sib txawv. nruab nrab ntawm lub hauv ntej thiab nram qab lub cev thiab lub laum yeeb nkab tuav.Nyob rau hauv tus txheej txheem ntawm drilling thiab towing, txawv txav quab yuam nyob rau hauv kev twb kev txuas xov ntawm laum yeeb nkab ua rau txawv txav ntawm kev twb kev txuas xov.

Drilling ceev

Thaum lub sij hawm kev tsim kho, lub drilling thiab rub rov qab ceev ntawm lub drilling rig yog ceev heev, uas ua rau kom lub zog rotational ntawm lub laum yeeb nkab thiab lub rotational torque ntawm lub laum yeeb nkab tshaj qhov siab tshaj plaws rotational torque, uas ua rau muaj kev puas tsuaj rau cov xov txuas. ntawm lub laum yeeb nkab.

Tsis zoo laum yeeb nkab

Txheeb xyuas cov kav dej tho uas nyuaj rau disassemble ntawm qhov chaw tsim kho.Yog tias cov xov txuas ntawm cov kav dej laum no puas thiab deformed, nws txhais tau tias lub zog ntawm cov xov txuas ntawm cov kav dej laum tsis txaus.

 

Kev daws teeb meem:

Kev xaiv raug ntawm cov yeeb nkab laum

Thaum teeb tsa lub laum yeeb nkab rau cov kev taw qhia drilling rig, lub laum yeeb nkab yuav tsum raug xaiv kom tsim nyog raws li cov av, thiab kev sib hloov torque ntawm cov laum yeeb nkab yuav tsum tau tswj nruj me ntsis.

 

Ua lub tshuab kom raug

Thaum lub sij hawm lub pipeline drilling / pullback kev tsim kho ntawm lub drilling rig, propulsion ceev ntawm lub hwj chim lub taub hau yuav tsum tau kom tsim nyog slowed down.

Cov neeg ua haujlwm yuav tsum raug cob qhia kom tsis txhob muaj lub zog ntau dhau ntawm qhov drilling rig vim qhov tsis paub ntawm qhov drilling rig thiab kev tsim kho geology, ua rau muaj kev puas tsuaj thiab deformation ntawm laum yeeb nkab txuas threads.

Laum yeeb nkab disassembly txoj kev

Thaum disassembling lub laum yeeb nkab, thawj zaug siv tus lwm yam rau niaj hnub disassembly.Tom qab tuav 2 ~ 4 lub laum cov kav dej hauv lub vice, xyuas seb cov hniav puas hnav.Yog hnav, hloov cov hniav hauv lub sijhawm.

Thaum lub laum yeeb nkab yog ib qho nyuaj rau disassemble, lub vise clamps lub laum yeeb nkab ntau tshaj 2 lub sij hawm, thiab nto ntawm lub laum yeeb nkab clamping ib feem yog hnav heev, lub disassembly yuav tsum tau nres tam sim ntawd.Siv cov pa oxygen acetylene nplaim taws los ci cov xov txuas ntawm cov yeeb nkab laum, lossis siv rauj rau vibrate cov xov txuas ntawm lub laum yeeb nkab kom disassemble.

Yog hais tias lub laum yeeb nkab tsis tuaj yeem disassembled los ntawm cov txheej txheem saum toj no, tsuas yog siv txoj kev nyem nyem.Cov txheej txheem tshwj xeeb yog: siv cov roj txiav los txiav ib daim duab peb sab ntawm cov xov sab hauv kawg ntawm lub laum yeeb nkab kom tso lub zog nruj, thiab tom qab ntawd cov yeeb nkab laum tuaj yeem raug tshem tawm.Txawm li cas los xij, vim yog tus nqi siab ntawm cov laum yeeb nkab, txoj kev txiav tawm lub siab nyem tuaj yeem ua rau nws nyuaj rau kev kho qhov txiav laum yeeb nkab, yog li txoj kev no yuav tsum tau siv nrog ceev faj.
