Gucukura imiyoboro ihindagurika ni iki?

Gucukura imiyoboro y'amazi isubira inyuma (Reverse Circulation Drilling) ni iki?

Gucukura hakoreshejwe uburyo bwa "reverse circulation" ni uburyo bwo gucukura bukoresha uduce twa PDC dusimburana, n'inkoni zifite inkuta ebyiri kugira ngo habeho gucukura no gukusanya ingero. Urukuta rw'inyuma rufite imiyoboro y'imbere ituma ibyaciwe bisubizwa hejuru mu gihe igikorwa cyo gucukura gikomeje.

Gucukura imiyoboro inyuma biracyatuma imiyoboro ifunguka ariko bitandukanye no gucukura diyama kuko bikusanya ibice by'amabuye aho gukusanya igice cy'imbere cy'amabuye. Iyi miyoboro ikoresha uduce twihariye two gucukura imiyoboro inyuma dutwarwa na piston ihinduranya umwuka cyangwa inyundo.

Utu duce two gucukura dukoresha amashanyarazi aturutse inyuma dukozwe muri tungsteni, icyuma, cyangwa uruvange rwabyo byombi kuko bikomeye bihagije gukata no gusya ibuye rikomeye cyane. Binyuze mu migendekere yaryo ya piston, inyundo ishobora gukuraho ibuye ryashegeshwe, hanyuma rigashyirwa hejuru n'umwuka ufunze. Umwuka uhuha mu gice cy'amazi. Ibi bituma habaho ihinduka ry'umuvuduko uvamo amashanyarazi aturutse inyuma, ari na byo byongera imiterere y'amazi mu muyoboro.

Gucukura imiyoboro y'amazi inyuma ni byiza cyane mu gupima amabuye yo munsi y'ubutaka mu rwego rwo gusesengura imiterere y'ubutaka no gukora urufatiro rw'amabuye.

Noneho ko umaze kumenya icyo ari cyo, reka turebere hamwe zimwe mu nyungu zo gucukura imiyoboro y'amazi mu buryo bwa reverse circulation.

Ifite akamaro mu kubona ingero zitanduye

Gucukura imiyoboro y’amazi mu buryo bwa reverse circulation bikuraho kwanduzwa kw’amabuye iyo agejejwe hejuru, kuko ibiti binyura mu muyoboro w’imbere ufunze ufite umwenge umwe gusa ku buso aho icyitegererezo gikusanyirizwa. Bityo, ushobora gukusanya ingero nyinshi nziza zo gusesengura.

Igipimo gitangaje cy'ubwinjirane

Uduce twihariye two gucukura inyuma y’urukuta turakomeye cyane kurusha utundi dusanzwe two kurangiza kubera utundi duce tw’icyuma cya tungsten. Imyitozo yo gucukura inyuma y’urukuta ikora ku muvuduko wihuta kandi igakuramo uduce twaciwe mu gihe gito cyane. Umuvuduko unyuramo uduce two gucukura hejuru ushobora kugaragara kuri metero 250 ku isegonda.

Guhindagurika mu bihe bibi

Gucukura imiyoboro y'amazi mu buryo bunyuranyije n'amategeko si ikintu kigoye kandi ntigisaba amazi menshi. Iki gikorwa gituma gucukura imiyoboro y'amazi mu buryo bunyuranyije n'amategeko biba byiza ndetse no mu turere tudakunze kubonekamo amazi menshi nko mu turere duto cyangwa mu turere tw’amazi make.

Ihendutse cyane

Gucukura imiyoboro isubira inyuma birahendutse cyane, cyane cyane ugereranije no gucukura diyama. Si ukubera gusa ikiguzi cyo gukora cyagabanutse, ahubwo no kubera igihe gito bifata kugira ngo urangize gucukura. Muri rusange, gucukura imiyoboro isubira inyuma bishobora kugabanya kugeza kuri 40% ugereranije no gucukura bisanzwe. Niba ucukura ahantu hari ubutaka bubi, igiciro gishobora kwiyongeraho kabiri.

Guhindura Inzira y'Umuvuduko mu Gihe cy'Ingano (Reverse Circuit Control)

Ubwiza bw'ibipimo byabonetse ni ingenzi cyane muri gahunda iyo ari yo yose yo gushakisha kugira ngo hakorwe igenamigambi ryiza ry'ibirombe cyangwa mu gushyira ibisasu. Kugenzura amanota ni byo bikoreshwa mu kugena imiterere y'amabuye n'imiterere y'amabuye y'agaciro. Gucukura imiyoboro y'amazi inyuma ni byiza mu kugenzura amanota kuko:

• Bisaba uburyo buke bwo kubikoresha ugereranyije n'ubundi buryo
• Ingero zabonetse nta kintu na kimwe cyanduye kirimo
• Igihe cyo guhindukira vuba
• Ingero zabonetse zishobora guhita zijyanwa muri laboratwari kugira ngo zisesengurwe

Ikintu cy'ingenzi cyane mu gikorwa cyo gucukura amazi mu buryo bunyura inyuma ni ugukata ingero. Uburyo bwinshi bushobora gukoreshwa mu kugarura ingero, ariko intego nyamukuru ni ukubona ingero nziza zishoboka mu gihe gito.

Niba ukeneye serivisi zo gucukura imiyoboro ikoresha ikoranabuhanga ryo gucukura imiyoboro ikoresheje ...uduce twa PDC dusimburanakugira ngo hirindwe gutinda guterwa n'uduce tw'imyobo twangiritse. Hanyuma, buri gihe menya neza ko igikorwa cyo gucukura gikurikije amahame ngenderwaho y'ibidukikije.
