TEMPERATURE DETECTION APPARATUS AND METHODS ALONG A WELL HOLE USING TEMPERATURE SENSOR MODULES CONNECTED TO A MOTHER

摘要

apparatus (100) for use in detecting temperature along a well, comprising: pipe (110) comprising a plurality of temperature sensor modules (120) provided at locations along the interior of the pipe, showing electrical properties that vary with temperature; and an electrical network (115) comprising a plurality of wires and said various temperature sensor modules,wherein the wires and various temperature sensor modules are configured as a matrix through which the wires comprise a first group of wires and a different second group of wires and each wire of the first group is electrically connected to each wire of the second group once. , by different temperature sensor modules, such that each temperature sensor module may be individually and electrically connected by a pair of wires comprising a first wire of the first group and a second wire of the second group.
