<p>The invention relates to a device for removing liquids from a drill hole equipped for extracting gases from a subterraneous formation when the flow of liquid through a production pipe string has a thin-film descending component. According to the invention, the device comprises a long lower inner jacket (4) whose upper end (b) is chamfered and which is surrounded by an M-shaped short-circuiting pipe (7) provided with some short vertical portions (j and k) which are secured at the lower side by some elbows (l and m) of an M-shaped discharge route (8) surrounding partially the lower inner jacket (4), the elbows (l and m) continuing downwards with some long vertical portions (n and o) and also with short vertical portions (p and q) which, in their turn, communicate between them through a horizontal lower portion (r), the long vertical portions (n and o) having a curved lower end (s) mounted in a window (t) cut in the lower inner jacket and an open end (u), located in the accumulation chamber (a), respectively.</p> |
