Abstract

Invenţia se referă la un dispozitiv pentru extragerea lichidelor din sonde prin gazliftare, destinat extracţiei de lichid din sonde, în special din acelea cu debit scăzut. Dispozitivul pentru extragerea lichidelor din sonde prin gazliftare, conform invenţiei, asigură ascensiunea lichidelor din sondă, prin aceea că este alcătuit din nişte ţevi (3 şi 4), concentrice, limitate şi solidarizate cu un niplu superior (5) şi cu un niplu inferior (7). Ţeava (3) interioară limitează o cameră de pompare (c) şi ţeava (4) exterioară limitează o cameră de comunicare (d). La partea superioară a niplului superior (5), este situată o cameră de acumulare (B). Camera de pompare (c) este prevăzută cu o supapă de admisie (11) şi cu un flotor (12) ce culisează pe o tijă (14) ce poate deplasa un sertăraş (16) distribuitor, montat într-o cavitate (o) a niplului superior (5). Niplul inferior este prevăzut cu o supapă de evacuare (21).The invention relates to a device for the extraction of liquids from wells by gaslifting, for the extraction of liquid from wells, especially from those with low flow rate. According to the invention, the device for extracting liquids from the gas wells according to the invention provides for the flow of the liquids from the well in that it consists of some concentric, limited and joined pipes (3 and 4) with a superior nipple (5) and a lower nipple 7). The inner tube (3) limits a pumping chamber (c) and the outer pipe (4) limits a communication chamber (d). At the top of the upper nipple (5) there is an accumulating chamber (B). The pumping chamber (c) is provided with an intake valve (11) and a float (12) sliding on a rod (14) that can move a dispenser (16) mounted in a cavity (?) of the upper nipple (5). The lower nipple is provided with an outlet valve (21).
