Ubushinwa Gukora Imyitozo ngufi
Ibisobanuro:
Imyitozo ngufi ya cola ikozwe mubyuma bikomeye cyane nyuma yo kuvura ubushyuhe. Imikorere yubukanishi nu murongo uhuza byujuje ibisabwa API. Ikoreshwa cyane cyane kubikoresho bidasanzwe bihujwe cyangwa bigize umubare runaka wibikoresho byo gucukura.
Imyitozo ngufi ya Drill Collars itanga ubukana bukenewe muguteranya umugozi wimyitozo kandi bigafasha kwirinda gutambuka kubushake bwa borehole. Ingano yacyo yoroheje ituma itanga umuriro mwinshi kandi ikongera umuvuduko wo kwinjira. Iza ifite akajagari cyangwa kuzunguruka hanze, bifite akamaro mukugabanya gutandukana gutandukanye. Nkigisubizo, Bigufi ya Drill Collar yemeza ko ibikorwa byo gucukura bikomeza kugenda neza kandi bidahagaritswe, bityo bikongerera ubushobozi rusange mubikorwa byo gucukura.
