Kodi zomwe zimayambitsa kusefukira pakubowola ndi chiyani?

Zinthu zambiri zingayambitse kusefukira mu chitsime chobowola. Nazi zina mwazoyambitsa zofala:

1.Drilling fluid circulation system kulephera: Pamene makina obowola amadzimadzi amalephera, angayambitse kupanikizika ndi kusefukira. Izi zitha kuchitika chifukwa cha kulephera kwa zida zopopera, kutsekeka kwa mapaipi, kutayikira, kapena zovuta zina zaukadaulo.

2.Kuthamanga kwa mapangidwe ndi kwakukulu kuposa momwe amayembekezera: Panthawi yobowola, kupanikizika kwenikweni kwa mapangidwe kungakhale kwakukulu kuposa momwe akuyembekezeredwa. Ngati njira zoyenera sizikuchitidwa panthawi, madzi obowola sangathe kulamulira kupanikizika kwa mapangidwe, kuchititsa kusefukira.

3.Kusasunthika kwa khoma: Pamene khoma la chitsime liri losakhazikika, lidzachititsa kuti matope awonongeke, zomwe zimapangitsa kutaya mphamvu ndi kusefukira.

4.Drilling ndondomeko zolakwa ntchito: Ngati zolakwa ntchito pobowola ntchito pobowola, monga kubowola bit clogging, kubowola dzenje lalikulu kwambiri, kapena kubowola mofulumira kwambiri, etc., kusefukira akhoza kuchitika.

5.Kuphulika kwa mapangidwe: Ngati kuphulika kwapangidwe kosayembekezereka kumapezeka panthawi ya kubowola, kusefukira kungathenso kuchitika.

Chonde dziwani kuti zifukwa zomwe zatchulidwa pamwambazi ndi chimodzi mwa zifukwa zodziwika bwino, ndipo zochitika zenizeni zimatha kusiyana malinga ndi dera, zochitika za geological, ntchito, ndi zina zotero. Panthawi yobowola, kuwunika kwatsatanetsatane kumayenera kuchitidwa ndikugwirizana. njira zowonetsetsa kuti kubowola bwino.
