摘要： Methods and apparatus are provided for determining an indication of a nonlinear property of the formation. A sonic tool is used in a borehole to generate a signal having multiple cycles of a wave of a predetermined frequency. The amplitude of a tube wave resulting from the signal is measured. The measured amplitude is then used to determine an indication of the nonlinearity of the formation according to a relationship which relates the measured amplitude to the amplitude of a second harmonic tube wave which is generated in the borehole by the tube wave of the predetermined frequency due to the nonlinear property of the formation. The indication of nonlinearity may then be utilized to give an indication of the relative consolidation of the formation surrounding the borehole.

摘要： An improved technique for determining the thickness of a member, especially pipe such as fluid-filled casing in an earth borehole, includes the following steps: directing a pulse of ultrasonic energy toward the inner surface of the pipe, and receiving and storing, as a function of time, signals representative of ultrasonic energy reflected from the inner surface of the pipe; determining, from the stored signals, the arrival time of the initial echo from the inner surface; determining, from the stored signals, thearrival time and the amplitude of a first candidate initial echo from the outer surface of the pipe; performing a reverse search on the stored signals to determine, from stored signals at times earlier than the arrival time of the first candidate, the arrival time and the amplitude of a second candidate initial echo from the outer surface; comparing amplitudes of the first and second candidates, and selecting, based on the comparison, one of the first and second candidates as the actual outer surface echo; and determining the thickness of the pipe from the arrival time of the actual outer surface echo and the arrival time of the inner surface echo. Using this technique, the earlier arriving candidate can be properly identified as the actual outer surface echo, even when the later arriving candidate has a greater amplitude.

摘要： After an oil well has been drilled, lined and cased, and is producing, it may be desirable in situ (either at the wellhead or downhole) to measure, and log (record), the rate at which fluid, and its several distinct components, is flowing out of the geological formations through which the bore has been drilled and is passing into and up the casing. A useful type of detector system for this purpose is an optical probe (31), and the invention proposes a novel design of probe which has a doubly-angled tip, there being measured the light totally internally reflected at the interface (37), which depends on the ratio of the refractive indices of the probe tip and fluid component in which it is immersed. The invention also proposes an improved method using such a tipped probe, in which, to facilitate distinguishing between the components of a multi-phase fluid such as the gas/water/oil formation fluid in an oil well, there is employed a pair of adjacent probes, one of which is designed to distinguish between gas and liquid and the other of which is designed to distinguish between oil and "not oil" (gas/water), and there are then logically combined the outputs of the two so as to give an indication of which component the probes are in.

摘要： Measurement-while-drilling apparatus includes a 14 Mev neutron accelerator, a near-spaced neutron detector which primarily senses source neutrons and whose output is proportional to source strength, one or more intermediately-spaced epithermal neutron detectors eccentered against the drill collar wall and primarily responsive to formation hydrogen concentration, and a third far-spaced radiation detector, either gamma ray or neutron, primarily responsive to formation density. The intermediately-spaced and far-spaced detector outputs, normalized by the near-spaced detector outputs, are combined to provide measurements of porosity, density and lithology and to detect gas. A thermal neutron detector and/or a gamma ray detector may also be provided at intermediate spacings to provide additional information of interest, such as standoff measurements and spectral analysis of formation composition. Tool outputs are related to the angular or azimuthal orientation of the measurement apparatus in the borehole.

摘要： A method of logging an underground formation from within a borehole (12) includes the steps of emitting an electromagnetic signal from a first location (20) in a borehole (12), determining a time at which the signal is emitted, detecting a direct component (D) of the signal which has passed from the first location (20) to a second location (22) without being reflected, determining a time at which the direct component (D) arrives at the second location (22) and determining the speed of the signal in the underground formation from the time at which the signal is emitted, the time of arrival of the direct component (D) and the spacing of the first (20) and second (22) locations. The speed of the signal can be used for radar logging of the formation. A logging tool for performing the method includes a transmitter (20) at a first position in a tool body for emitting an electromagnetic signal, means located in the tool body for determining a time at which the signal is emitted, a receiver (22) at a second position in the tool body for detecting a signal which has passed from the transmitter to the receiver through an underground formation; and means (22) located in the tool body for processing the detected signal using the time at which a corresponding signal is emitted from the transmitter.

摘要： An electrochemical sensor utilises a chemical compound which is not a macromolecule but rather is a single chemical compound of determinate structure, incorporating two redox systems which differ in their response to a species to be detected. In one form, one redox system displays a voltammetric wave which is pH dependent while another displays a voltammetric wave which is pH independent and acts as an internal reference. The sensor comprises a solid substrate, which may be carbonaceous, on which the compound is immobilized. The sensor may be incorporated into a tool to be suspended in a wellbore.
