I-Wireline Logging - Ukubhobozwa

Lesi sihloko sixoxa nge-perforating casing ngokusetshenziswa kocingo lwe:

ukwenza i-casing casing cementing, ngokucindezela ngemibhobho kanye

ukuqapha (ukwakheka) izingcindezi ngemuva kwebhokisi.

I-casing perforation

Umhlangano kufanele ubanjwe ngaphambi kokuqoshwa kokubhobozwa, kukhona nabasebenzi abalandelayo:

● Unjiniyela Wokugawula Amahlathi/ Isazi sokuma kweNdawo Yendawo

●I-Well Service Supervisor, njengoba kufanele

●I-Wireline Operations Supervisor

●Drilling Supervisor

●Well Site Drilling Engineer

Inhloso enkulu yomhlangano ukuthi:

●Cacisa imigqa yokubika neyokuxhumana.

●Xoxa ngokusebenza.

●Xoxa nganoma yiziphi izimo ezikhethekile, isib. izimo zezulu, isimo sembobo, ukuthula komsakazo, isikhathi, ukusebenza ngasikhathi sinye, njll.

Ngaphezu kwalokho, kufanele kubanjwe ingxoxo yangaphambi komsebenzi nabasebenzi abagawula imithi kanye nokumba.

Ngaphambi kokuba isibhamu siqhunyiswe emgodini, kwenziwa i-dummy run, ukuze kubhekwe ukuthi i-tubing/casing ayinazo yini izithiyo. I-dummy kufanele ibe ne-OD efanayo. njengesibhamu sokubhoboza okufanele sisetshenziswe. Ukuqaliswa kokungena okwenziwa ngaphambilini ngaphandle kwezithiyo okuhlangatshezwane nazo, kungase kubhekwe njengokugijima okungaqondile, okungase kukhishwe ngaphansi kwezimo ezinjalo, ngaphansi kwengxoxo ne-Base.

Uma ukucindezela kulindeleke ukuthi kukhishwe ngesikhathi sokubhobozwa, noma uma indawo ekwazi ukungena ibhobozekile, i-BOP yocingo, okokugcoba kanye nebhokisi lokugxusha lizofakwa esikhuphukeleni sezintambo esifakwe ingono phezulu kwe-BOP. Ngekhanda lekhebula ku-lubricator, ingcindezi ihlola okokusebenza kungcindezi edingekayo.

Qiniseka ukuthi awekho ama-voltage adukayo ekhanda lekhebula, noma amandla kagesi phakathi kwerigi ne-casing, kanye nokuthi iyunithi yocingo ifakwe uthuli ngendlela efanele.

Linganisa ubude besibhamu ngasinye kanye nebanga phakathi kweshothi yokuqala ne-CCL/GR, uma sihlanganiswa.

Ngesikhathi sokuphatha izibhamu, abasebenzi abangabalulekile kumele bakhishwe endaweni yokusebenza.

Uma izibhamu zihlomile bonke abasebenzi kufanele bangangeni emlilweni, kuze kube yilapho isibhamu siphephile emthonjeni.

Ukuxhumana Okujulile

Qalisa i-casing collar locator (CCL) kanye namalogi e-gamma-ray (GR) kuso sonke isikhawu ukuze ambobozwe. Rekhoda ilogu ekujuleni kokubhoboza, futhi uhlobanise namalogi e-gamma-ray asetshenziswa ngaphambilini kumalogi ezithenjwa. Ukuqinisekisa ukuthi isibhamu sikujule okulungile ngaphambi kokudubula, izibalo zokujula kufanele zihlolwe ngokuzimele kabili, ngaphambi kokugunyaza unjiniyela wokugawula adubule izibhamu.

Ngesikhathi sokudubula, bheka izinkomba zokuthi kuqhume isibhamu.

Izinga lodaka embobeni kufanele libhekwe ngokucophelela ngokulahleka noma izinzuzo phakathi nokugawulwa kwemithi, futhi ikakhulukazi ngaphambi kwe-POH. Imbobo kufanele igcinwe igcwele ngaso sonke isikhathi.

Lapho ukuhlangana kwe-perforating kulandwa, qiniseka ukuthi isibhamu siphezulu ku-lubricator ngaphambi kokuvala i-valve yolayini wocingo.

Uma isibhamu sibekwe ku-catwalk sizobhekwa ukuthi akunacala yini.

Izibhamu ezigqobhoza amandla ziyaklanywa, zikhiqizwe, zihlolwe futhi zihlolwe ngezinga eliphezulu lemboni, futhi sibheke ngabomvu ukusebenzisana namakhasimende ethu ukuze sibambe iqhaza ekuthuthukisweni kwemboni kawoyela negesi. Uma udinga noma yiziphi izibhamu zokubhoboza noma ukumba nokuqedela ukugawulwa kwemithi, sicela ungangabazi ukuxhumana nathi ukuze uthole ukwesekwa komkhiqizo osezingeni eliphezulu kanye nenkonzo eseduze kakhulu.
