摘要： The present invention provides a system for determining downhole conditions including a time domain reflectometer (172) that is operable to generate a transmission signal and receive a reflected signal. A tubular (192) is positioned downhole in a downhole medium (214, 216, 218, 220, 222) and a waveguide (186), which is in electrical communication with the time domain reflectometer (172), is operably contacting the downhole (214, 216, 218, 220, 222). The waveguide (186) is operable to propagate the transmission signal and operable to propagate the reflected signal that is generated responsive to an electromagnetic property of the downhole medium (214, 216, 218, 220, 222).

摘要： A fluidic oscillator can include a fluid switch, at least two fluid paths from the fluid switch, and a sensor which measures a frequency of fluctuations in flow through the fluidic oscillator. A method of measuring a flow rate of a fluid can include flowing the fluid through a fluidic oscillator, a majority of the fluid flowing alternately via at least two fluid paths from a fluid switch of the fluidic oscillator, and a sensor detecting a frequency of the flow alternating between the fluid paths. Another fluidic oscillator can include a fluid input, at least two fluid paths from the fluid input to respective fluid outputs, whereby a majority of fluid which flows through the fluidic oscillator flows alternately via the fluid paths, and a sensor which detects pressure fluctuations due to the flow alternating between the fluid paths.

摘要： A method is provided for monitoring a well. In a described embodiment, the method uses annulus pressure to communicate between a downhole system and a remote location. The method may use intermittent electrical power generated by changes in annulus pressure to power the downhole system. Various sensors and well tools may be monitored and actuated by the downhole system, and acquired data may be transmitted to the remote location.

摘要： Methods of controlling a downhole tool in a well are disclosed wherein pressure change signals are introduced into a column of fluid standing in the well. The command signal includes at least one high level pressure change applied to the column of fluid. The high level pressure change includes a change from a first value to a second value, with the second value being at least about 1,000 psi above hydrostatic pressure of the column of fluid in the well, and with pressure being maintained at the second value for an interval of time corresponding to information stored in a control system of the downhole valve. A number of suitable command signal formats are disclosed, particularly including pressure drop signals.

摘要： An electric coupling for two electric circuits in a well includes an electric contact and a contact receiver connected to respective ones of the circuits so that a contact/receiver pair is formed when the contact and receiver are moved together The receiver is sealed by a sealing member. The sealing member is disposed so that it is penetrated by the contact when the contact and receiver are moved together. A coupling including two such pairs is preferably used to connect two electric wires in the well to form a current conductive loop linking two electric coils. One of the coils is adapted to be moved in the well relative to the other coil which is adapted to be fixed in the well. In a preferred embodiment, one coil is on a wireline tool and the other coil is on a downhole tool. The current conductive path established across an intervening space between the tools is electrically insulated from the bodies of the tools and preferably has a resistance sufficiently low that the current conductive path is not effectively short-circuited by fluid in the intervening space which the path crosses.

摘要： A downhole electrical power supply apparatus has a high fluid pressure source zone and a low fluid pressure discharge zone each defined at least partially within the apparatus. A fluid powered engine provides rotational mechanical output and is powered by fluid flowing from the source zone through the engine to the discharge zone. An electrical powered generator converts the rotational mechanical output of the engine into electrical output.
