摘要： The present document describes a sensing apparatus for lowering into a well and cementing therein at a certain depth. The sensing apparatus comprises an elongated casing and a sensor device protruding from an outside surface of the elongated casing for generating measurement data and sending the data to the surface of the well using a cable extending from the sensor device along the outside surface of the casing. A flow of cement is provided between the outside surface of the casing and the well for cementing the casing in place and isolating different layers of the well. Presence of the sensor device and the cable creates an obstruction within the flow path of the cement which may result in the formation of micro-annulus around the sensor device and the cable. In order to address this problem, a plurality of fins is provided around the casing, the fins being shaped to cause a straight flow of cement received at the fins to rotate around the longitudinal axis of the casing when exiting the fins for increasing cement flow between the elongated casing and its surrounding environment to mitigate micro-annulus formation. Another means to address this problem is to provide cable attachments which distance the cable from the casing and thereby let cement flow between the cable and the casing also mitigating micro-annulus formation.

摘要： A coil of continuous steel tubing string is stretched along the ground. An elongate bundle of instrument lines, including thermocouples and pressure sensor wiring, is threaded into the bore of the tubing string. The instrument lines are landed at multiple spaced apart measurement points along the string. The string and the contained bundle are cut at pressure measuring points. A tubular sub having a side port is supplied for each point. One set of cut line ends is threaded through the sub and reconnected with the other set. A pressure sensor is inserted in the string at the cut point and connected with pressure sensor wiring and the port. This process is repeated along the tubing string. The product is a continuous tubing string housing a plurality of pressure sensor assemblies connected to ports along the string and a plurality of thermocouples operative to measure temperature at points along the string. The pressure sensor assemblies and thermocouples are operative to transmit their measurements through the dry tubing bore to ground surface.
