Ibikoresho byo gusya downhole bifite ubushobozi bwo hejuru

Ibisobanuro bigufi:

Ibikoresho byo gusya bikoreshwa mu gusya amafi n'ibindi bikoresho byo mu mazi, gusukura imyanda yo ku rukuta (urukuta rw'imyobo) cyangwa gusana isanduku. Ihame ni ugusya amafi mo imyanda munsi y'umugozi uzunguruka n'igitutu cy'umugozi ukoresheje tungsten carbide ihambiriwe ku gice cyo gukata cy'igikoresho cyo gusya, kandi imyanda ishobora kongera gukoreshwa mu gusya ikongera ku butaka hakoreshejwe amazi yo gucukura.
Ubwoko bwinshi bw'ibikoresho byo gusya bukunze gukoreshwa mu miterere yabyo, mu gihe hakurikijwe imiterere itandukanye y'amafi, hakenewe ibice bihuye byo gukata. Ibice bikunze gukoreshwa mu gusya bishobora gushyirwa imbere, inyuma no mu mpera z'ibikoresho byo gusya.
Nyuma yo gushushanya no kwegeranya ikoranabuhanga mu myaka ya vuba aha, byahuye n'ibyo abakiriya baturutse mu Bushinwa no mu mahanga bakeneye bitewe n'imikorere yabo yizewe. Uretse ubwoko n'ingano byavuzwe mu bikubiye muri ibi bikurikira, twishimiye kandi gukora hakurikijwe imiterere yihariye ishobora guhaza ibyo abakiriya bakeneye.

Uruganda rwa Taper

Uruganda rwa Taper rukora inzitizi, rukora isanduku n'ibice by'imigozi byasenyutse, rukora n'amadirishya n'ibice by'imigozi byasenyutse. Igice cyo hasi cy'uruganda rwa Taper, gifite umurambararo muto, cyinjira mu gasanduku kasenyutse n'umugozi. Hanyuma impande z'uru ruganda zizunguruka gato kugira ngo rukure igice cyo munsi kugeza ku murambararo wuzuye w'uru ruganda.

Uruganda rwa Taper rugizwe n'umubiri ufite ishusho y'urukiramende na karubide ya tungsten. Umubiri ufite ishusho y'urukiramende ifite dogere 30, agace k'urukiramende gafite ishusho nk'iy'amababa, kandi ubuso bwarwo bufite ishusho ikomeye cyangwa iy'urukiramende rwa tungsten.
