摘要： A method for measuring the linear flow velocity, radial position, direction, and the flow rate of water flowing within and behind a well borehole casing. A logging tool containing a source of essentially monoenergetic 14 MeV neutrons and at least one gamma ray detector is positioned within the well borehole opposite the zone in which water flow measurements are desired. The neutron source is turned on thereby irradiating any flowing water and other areas in the vicinity of the well borehole with high energy neutrons. After a predetermined irradiation time, the neutron source is turned off. Following a quiescent period of several milliseconds to allow thermal capture gamma radiation to decay to a negligible level, the gamma ray detector is turned on and the count rate from the N-16 induced within the flowing water is recorded as a function of time. The linear flow velocity, the Full Width Half Maximum time period, and the total count are determined directly from the resulting count rate curve. The radial position and the flow rate are determined using the predetermined relationship between the Full Width Half Maximum time period, radial position, and linear flow velocity, and the predetermined relationship between linear flow velocity, radial position, and the ratio of the flow rate to the total count for the logging tool. The direction of flow is determined by sensing the presence or absence of flowing N-16 above or below the source.

摘要： A system for use in cased well boreholes for measuring gamma ray spectra induced by bombardment of earth formations in the vicinity of the borehole with fast neutrons. Monoenergetic fast neutrons emitted in repetitive pulses penetrate the borehole structure and enter earth formations in the vicinity of the borehole and are moderated by elastic and inelastic scattering to thermal energy and captured by the nuclei of elements in and about the borehole. A scintillation detector optically coupled to a photomultiplier detects gamma radiation induced by the neutrons and produces electrical pulses with amplitudes representative of the energy of gamma rays. A pulse height analyzer connected to the output of the detector and photomultiplier separates the electrical pulses into a spectrum representative of the gamma ray energy spectrum. A timing circuit generates time gate signals to separate the electrical pulses into those of fast neutron induced gamma rays, thermal neutron capture gamma rays, and background gamma rays prior to sending the pulses to the pulse height analyzer. The timing cycle has a fast subcycle in which pulses representative substantially only of fast neutron induced gamma rays and thermal neutron capture gamma rays are sent to the pulse height analyzer and a slow subcycle portion in which pulses substantially representative only of thermal neutron capture gamma rays and background gamma rays are sent to the pulse height analyzer.

摘要： A method of data conversion is set forth. In this system, the amplitude of a borehole sidewall response is recorded as a data record. This includes a sinusoidal representation of an interface. Several points on the sinusoidal curve are transformed in parameter space to represent dip and strike of the interface. Multiple point transform provides quality data so that noise on the signal has reduced impact. The transform is the Hough Transform into parameter space. This can be used with BHTV to provide acoustic data representing the sidewall of the well.

摘要： A seismic logging system for VSP or cross well data capture set forth. It is comprised of M duplicate recording stations connected serially below a main structure suspended on a logging cable. Each of the recording stations preferably includes orthogonally arranged displacement transducers, and they are in turn connected with suitable amplifiers, filters and converters to form digital words, and the digital words are recorded in organized fashion in a memory. A telemetry unit is connected to that memory for transfer of data. This data transfer takes place over a short distance into the main unit, and the main unit includes a much larger memory for storing and holding data from M recording stations deployed along and there below in the well borehole, and further including telemetry means for transfer of data along the logging cable. The main memory and the main telemetry means operate at different rates and different capacities; each recording station has its own memory and telemetry means to individually form data words which are first stored locally and then transferred to the main memory where upon telemetry along the logging cable subsequently occurs.

摘要： A stretch corrected wireline depth measuring system is set forth including method and apparatus. It forms a log quality indication which indicates those occasions where the tool velocity is outside acceptable limits. The apparatus utilizes calibrated encoder wheels, preferably a redundant and duplicate pair, to form pulse trains indicative of surface wireline velocity. Additional measurements are made of wireline tension, and magnetic marks on the wireline are observed. All of this data is input to a CPU which determines the raw depth, and adjusts this value with depth corrections. The device calculates wireline stretch as a function of tension and total wireline in the borehole. This enables formation of output data as a function of depth including cable tension, tool speed, depth correction and log quality in the event that tool velocity is outside an acceptable range.

摘要： A fluid flow and simultaneous fluid density measuring device is set forth. The preferred embodiment incorporates a sonde having a lower inlet port, an upper outlet port, a lengthwise tube extending through the sonde and connected with the ports. A packer provides external isolation to direct all fluid flow into the tube. A float within the tube is buoyantly raised primarily as a function of fluid velocity and fluid density, and the position of the float is measured by placing a radioactive source in the float and measuring the count rate at spaced detectors to ascertain float location. Fluid is simultaneously measured by determining the radiation count rate attenuation of the fluid. With other fixed parameters and measurement of the float position and fluid density, the fluid flow rate can be determined. Both method and apparatus are set forth.

摘要： An igniter is set forth in the present disclosure for use with a coring gun assembly. A bullet equipped with a bottom and having an O-ring thereabout is positioned in a chamber at one end thereof for firing to take a core sample. At the opposite end, an igniter is positioned in the chamber resting primarily on a shoulder aligning an elongate cylindrical shell within the chamber and having an external O-ring for sealing purposes. An elongate electrically insulated conductive firing pin extends through said shell so that an external circuit can be connected thereto to create a firing pulse. The current flows through the pin and through a bridgewire disc positioned at the end of the pin which in turn ignites a prepackaged cylindrical explosive charge to fire the bullet.
