Wireline Logging - Perforation

Perforation ntawm lub qhov

Lub rooj sib tham yuav tsum muaj ua ntej rigging li perforation, nrog rau cov neeg ua haujlwm hauv qab no:

• Logging Engineer / Well Site Geologist
• Zoo Service Supervisor, raws li muaj
• Wireline Operations Supervisor
• Drilling Supervisor

Qhov Chaw Drilling Engineer

• Lub hom phiaj tseem ceeb ntawm lub rooj sib tham yog:
• Qhia kom meej cov kab lus qhia thiab kev sib txuas lus.
• Sib tham txog kev ua haujlwm.

Sib tham txog tej xwm txheej tshwj xeeb, xws li huab cua, qhov xwm txheej, xov tooj cua silence, sij hawm, kev ua haujlwm ib txhij, thiab lwm yam.

Tsis tas li ntawd yuav tsum muaj kev sib tham ua ntej ua haujlwm nrog cov txiav thiab cov neeg ua haujlwm laum.

Ua ntej rab phom khiav hauv lub qhov, ua kom dummy khiav, txhawm rau xyuas tias cov tubing / casing tsis muaj kev cuam tshuam. Lub dummy yuav tsum muaj tib yam OD. raws li rab phom perforating siv. Kev txiav tawm khiav yav dhau los uas tsis muaj kev cuam tshuam tau ntsib, tuaj yeem suav tias yog kev khiav haujlwm dummy, uas nyob rau hauv cov xwm txheej zoo li no yuav raug cais tawm, raug kev sib tham nrog Base.

Yog hais tias lub siab yuav tsum tau tso tawm thaum lub sij hawm perforation, los yog yog ib tug permeable cheeb tsam yog perforated, ib tug wireline BOP, lubricator thiab cov khoom ntim yuav tsum tau rigged rau ntawm ib tug wireline riser nippled rau saum BOP. Nrog rau lub taub hau cable hauv lub lubricator, lub siab ntsuas cov cuab yeej mus rau qhov xav tau siab.

Xyuas kom tseeb tias tsis muaj qhov tsis txaus ntseeg nyob rau hauv lub taub hau cable, lossis qhov muaj peev xwm muaj peev xwm ntawm rig thiab casing, thiab tseem hais tias chav tsev wireline yog zoo earthed.

Ntsuas qhov ntev ntawm txhua rab phom thiab qhov kev ncua deb ntawm thawj txhaj tshuaj thiab CCL / GR, thaum sib dhos.

Thaum txhua qhov tuav phom, cov neeg ua haujlwm tsis tseem ceeb yuav tsum raug cais tawm ntawm thaj chaw ua haujlwm.

Thaum phom phom tag nrho cov neeg ua haujlwm yuav tsum tawm ntawm txoj kab hluav taws, kom txog thaum rab phom nyob hauv qhov dej nyab xeeb.

Depth Correlation

Khiav casing dab tshos locator (CCL) thiab gamma-duab tshav (GR) log hla tag nrho lub caij kom tau perforated. Sau cov cav ntawm qhov tob perforation, thiab sib raug zoo nrog yav dhau los khiav gamma-ray cav ntawm cov ntaub ntawv siv. Txhawm rau kom ntseeg tau tias rab phom nyob ntawm qhov tseeb qhov tob ua ntej yuav tua, cov kev ntsuas qhov tob yuav tsum tau kuaj nws tus kheej ob zaug, ua ntej tso cai rau tus kws txiav ntoo kom tua cov phom.

Thaum lub sij hawm detonation, saib xyuas qhov qhia tias rab phom tau raug rho tawm haujlwm.

Cov av nkos hauv lub qhov yuav tsum tau ua tib zoo saib rau kev poob lossis kev nce qib thoob plaws hauv kev nkag mus, thiab tshwj xeeb ua ntej POH. Lub qhov yuav tsum tau khaws cia tag nrho txhua lub sijhawm.

Thaum lub rooj sib dhos perforating raug muab rov qab, xyuas kom meej tias rab phom nyob rau saum lub lubricator ua ntej kaw cov hlau-kab valve.

Thaum rab phom tau tso rau ntawm txoj kev taug kev, nws yuav tsum tau kuaj xyuas qhov tsis raug nqi hluav taws xob.

Raws li cov kws tshaj lij tshaj lij ntawm cov khoom siv perforating thiab ua tiav, Vigor cov kws tshaj lij engineer pab pawg muaj kev paub zoo thiab kev nkag siab tshwj xeeb ntawm kev tsim thiab siv cov phom perforating, thiab Vigor pab pawg engineering tau txhim kho peb tus kheej cov phom perforating kom ntseeg tau tias peb cov khoom tuaj yeem pab peb cov neeg siv khoom. ua kom tiav qhov chaw tsim kho kom zoo tshaj plaws. Yog tias koj txaus siab rau Vigor's perforating phom series khoom, thov tsis txhob yig tiv tauj peb kom tau txais cov kev pabcuam tshaj lij thiab cov khoom zoo tshaj plaws thiab cov kev pabcuam.
