Abstract: PCT No. PCT/NO96/00256 Sec. 371 Date Aug. 5, 1998 Sec. 102(e) Date Aug. 5, 1998 PCT Filed Oct. 28, 1996 PCT Pub. No. WO97/16623 PCT Pub. Date May 9, 1997Inflow regulation device for a production pipe for production of oil or gas from an oil- and/or gas reservoir (9), where the production pipe comprises a lower drainage pipe with drainage pipe sections (5) with one or more drainage pipe elements (2; 2a, 2b) having opening(s) (3; 3a, 3b) for inflow of oil and/or gas to an inner space (8) of the drainage pipe section. The inflow may be regulated by a movable sleeve (1) that abuts one adjacent side surface of the drainage pipe section (2; 2a, 2b) and where the sleeve is provided with a portion(s) (6) being able to cover/uncover the opening(s) in the drainage pipe element. The sleeve further comprises helical spurs/recesses (14, 15) that in conjunction with one adjacent abutting surface (18, 21) of the drainage pipe element (2; 2a, 2b) forms channels (16, 17) that may connect the reservoir (9) with the inner space (8) of the drainage pipe. The helical spurs/recesses (14, 15) may be constituted by one or more pair(s) of left- and/or right-oriented spurs/recesses. The sleeve (1) is axially movable by a double-acting ring piston device (21, 22) or by thread means (12, 13) arranged between the sleeve (1) and the drainage pipe element (2; 2a, 2b).
