ABSTRACT:
Production of pertroleum deposits in which water is mixed with the hydrocarbons. The quality of separation is controlled by incorporating within a packer (200) a regulated valve (100) which receives the flow of reinjection water after its separation in a unit (7), the water passing into a fluorescence analyzer (4). The results of the measurement are transmitted to a microprocessor unit (12) which produces a signal which actuates a hydraulic pump (9), which in its turn, actuates the valve (100). Separation of water from the hydrocarbons at the bottom of the well and control of the quality of the separation are effected before the reinjection of the water in a subterranean deposit zone (3).
