Fluid property sensor system

摘要

The present invention relates to fluid property measurement in a subterranean well. A Sensor system is provided as comprising a tubular string 18 positioned in a wellbore with a port 32 formed through a sidewall of the string 18 and providing fluid communication between an internal flow passage 40 of the string 18 and a zone 12 intersected by the wellbore. At least one sensor 62 is provided for sensing pressure of fluid flowing through a flow restriction 56 in the flow path between the zone 12 and the port 32.
