AN APPARATUS FOR AUTONOMOUS DOWNHOLE LOGGING AND WIRELESS SIGNAL TRANSPORT AND A METHOD FOR GATHERING WELL DATA

摘要

An apparatus (11) for autonomous, downhole logging of well data and wireless transport of the well data out of a fluid well (1), the apparatus (11) being provided with at least one sensor (24) arranged for registration of one or several types of relevant well data, wherein the apparatus (1) comprises: means (23) arranged so as to be able to transmit the well data from the at least one sensor (24) to at least one data storage unit (51), and also means (16, 17, 22, 23) arranged to release the at least one data storage unit (51) into a fluid flow in the fluid well (1). The invention also concerns a system for autonomous, downhole logging of well data and wireless transport of the well data out of a fluid well (1), and also for reading off the gathered well data. The invention also concerns a method for gathering well data through use of the system.
