Development of a resource-saving, small-sized downhole hydraulic machine for well drilling

Abstract: Аналізом структурних особливостей і технологічних можливостей серійних забійних гідродвигунів (гідромашин), призначених для буріння свердловин, встановлені їх недоліки. Це обмежені ресурси, обумовлені складністю конструкції, витрата робочої рідини, значні габаритні розміри по довжині, маса, низькі частоти обертання валу, що не відповідають технологічним режимам алмазного буріння свердловин. З аналізу конструктивних схем забійних гідродвигунів зроблено висновок, що найбільші можливості для максимального викорис… Show more

“…From the practice of developing groundwater deposits, it is known [2] that the hydro-impulse method of well development with alternating impact of shock waves on aquifers gives the maximum effect and allows, under certain conditions, not only to restore the permeability of the aquafer, but also artificially increase it.…”

“…To do this, a bottom-hole assembly was formed consisting of: a hydraulic machine, small in length, with low consumption of working fluid, a core barrel with non-rotating centralizers and a floating core receiver, thin-walled diamond bits with a separate system of flushing ports and a hydrojet effect of rock destruction [1,2].…”

“…Abroad, there are turbodrills whose rotational speed reaches 2500 rpm, for example, Neyrfor TTT 2 1/8 [21] and Neyrfor TTT 2 7/8 [22], developed by Schlumberger [23,24]. However, these turbodrills have a significant limitation associated with their diameter, hence the small working area of the blades, due to which the hydraulic energy of the drilling fluid flow is converted into the rotation of the turbodrill shaft [25,26].…”
