摘要： A system for use with a subterranean well can include a magnetic sensor, a magnetic device which propagates a magnetic field to the magnetic sensor, and a barrier positioned between the magnetic sensor and the magnetic device. The barrier can comprise a relatively low magnetic permeability material. A method of isolating a magnetic sensor from a magnetic device in a subterranean well can include separating the magnetic sensor from the magnetic device with a barrier interposed between the magnetic sensor and the magnetic device, the barrier comprising a relatively low magnetic permeability material. A well tool can include a housing having a flow passage formed through the housing, a magnetic sensor in the housing, and a barrier which separates the magnetic sensor from the flow passage, the barrier having a lower magnetic permeability as compared to the housing.

摘要： Methods of actuating a well tool can include releasing chemical energy from at least one portion of a reactive material, thermally expanding a substance in response to the released chemical energy, and applying pressure to a piston as a result of thermally expanding the substance, thereby actuating the well tool, with these steps being repeated for each of multiple actuations of the well tool. A well tool actuator can include a substance contained in a chamber, one or more portions of a reactive material from which chemical energy is released, and a piston to which pressure is applied due to thermal expansion of the substance in response to each release of chemical energy. A well tool actuator which can be actuated multiple times may include multiple portions of a gas generating reactive material, and a piston to which pressure is applied due to generation of the gas.

摘要： The disclosure describes a method and apparatus for effectively communicating data along an acoustic transmission path. The method comprises driving an acoustic transmitter to send a data signal along the acoustic transmission path, where the signal is distorted by ambient noise. The distorted signal is input to a spaced apart plurality of sensors so that consequent time-delayed signals provide reinforcement of the basic signal and attenuation of the ambient noise component when combined.
