SYSTEM AND METHOD FOR PRODUCTION OF A PRIMARY FLUID, SUCH AS OIL, FROM AN UNDERGROUND RESERVOIR

摘要

The invention relates to a system and a method for production of a fluid from an underground reservoir. The system comprises a casing (10) with an internal tubing (11). At least one plug-in device to be received in the tubing, Means for wire line installation and retrievement of the plug-in device; Means for (un)locking and means for sealing the plug-in device in the casing. Two secondary fluid lines (15) alongside the tubing are connectable to the plug-in device for operating. The system comprises one or more plug-in devices, each comprising at least one functional section, wherein for pumping devices the first functional section comprises a drive for a pump, which is connectable to the drive such that the pump lies closer to the reservoir than the drive in the position of use. The plug-in devices can be placed at different positions P1 through P6 in the tubing.
