DEVICE AND PROCESS FOR MONITORING THE POSITION OF AN OIL / WATER CONTACT

摘要

"device and process for monitoring the position of an oil / water contact". a device for monitoring the position of an oil / water contact (owc, 22) between a continuous oil fluid (2o) that overlaps with a continuous water fluid (2w) within a casing tube (7) comprising the following aspects: a transmitter (5) for generating an electromagnetic signal (s ~ t ~), said transmitter (5) provided with electrical energy (g ~ t ~) from a voltage signal generator (g); said transmitter (5) being arranged within said oil continuous fluid (2 °), and which is above said oil / water contact (22) and which is within said casing tube (7); said electromagnetic wave signal (s ~ t ~) to partially propagate downwardly from said transmitter (5); said electromagnetic wave signal (s ~ t ~) to be partially reflected from said oil / water contact (22) and partially reflected by the end of the coating, giving rise to a reflected electromagnetic signal that propagates upwards (s ~ r ~); a sensor (6) for detecting said reflected electromagnetic signal (s ~ r ~), and said sensor (6) also arranged above said water / oil contact (22), which provides a sensor signal (r ~ r ~) for a receiver (60) for receiving said sensor signal (r ~ r ~) and further for an analyzer device (61) for analyzing said sensor signal (r ~ r ~), for example with respect to propagation time in two directions or amplitude to calculate an elevation level for said oil / water contact (22).
