摘要： A device and a method for selective control of fluid flow between a flow pipe (14) of a well and surrounding rocks (12). The flow pipe (14) is provided with at least one flow-through particle filter (16) placed externally on the flow pipe (14) and between the flow pipe (14) and the rocks (12). The filter (16) is connected in a flow-through manner to the flow pipe (14) via a flow channel (38). The characteristic of the invention is that the flow pipe (14) is provided with an imperforated pipe wall inside of and vis-a-vis said flow channel (38) when installing the flow pipe (14) in the well. Then the flow pipe (14) may be perforated selectively inside of the flow channel (38) for one or several filters (16) along the flow pipe (14), whereupon fluids may flow through the flow channel (38) and the filter (16) via perforation apertures (54) in the flow pipe (14).

摘要： A downhole measurement device includes one or more sensors configured to measure a parameter in a well; a plurality of memory tags for storing measurement data from the one or more sensors; and an ejection module configured to release one of the plurality of memory tags upon a predetermined condition. A method for monitoring a well includes deploying of a measurement device having one or more sensors and a plurality of memory tags into a wellbore; obtaining measurement data of the parameter using the one or more sensors; writing the measurement data to one of the plurality of memory tags; releasing the memory tag having the measurement data; allowing the memory tag having the measurement data to be carried by a flow in the wellbore uphole; reading the measurement data from the memory tag having the measurement data at a location remote from the downhole measurement device.
