    摘要： A method and apparatus for locating a collar of a casing of a wellbore is disclosed. A sensor for measuring a magnetic field is conveyed through the casing on a tool string. A physical model is formed of a process of obtaining a magnetic measurement of the casing with the sensor. A simulation of the physical model is run through a processor to select a design parameter of the tool that allows for using the sensor at a determined value of an operational parameter for obtaining the measurement at a selected signal-to-noise ratio. The tool is conveyed into the wellbore and the sensor set to the determined value of the operational parameter. The magnetic measurement of the casing is obtained using the sensor, and the collar is located using the obtained magnetic measurement.

    摘要： A system and method for orienting a tool in a near vertical wellbore. The system includes a tool string having a whipstock at an end thereof, at least two magnetometers oriented transverse to a longitudinal axis of the tool string, and a processor. A first set of magnetic measurements of the earths' magnetic field is obtained during rotation of the tool using a first of the at least two magnetometers and a second set of magnetic measurements of the earth's magnetic field is obtained during rotation using a second of the at least two magnetometers. The processor fits a curve to the first and second sets of magnetic measurements to determine a peak value, determines magnetic north from the determined peak value, determines a toolface orientation of the drill string with respect to the determined magnetic north, and anchors the whipstock at the selected depth and toolface orientation.

    摘要： An apparatus for determining a location of a downhole component includes at least one transmitter device and a receiver device. One of the at least one transmitter device and the receiver device is disposed at a first component of a borehole string configured to be deployed in a borehole and retained at a stationary position, and another of the at least one transmitter device and the receiver device is disposed at a moveable component configured to be moved while the first component is at the stationary position, the at least one transmitter device configured to emit a wireless signal and the receiver device configured to detect the wireless signal when the first component is at the stationary position. The apparatus also includes a processing device configured to receive signal data and estimate a location of the moveable component relative to the first component based on the signal data.

    摘要： An improved heat exchanger for an automotive vehicle, comprising at least one end tank; and at least two heat exchangers including a plurality of spaced apart metal tubes with fins between the spaced tubes. The heat exchangers are preferentially disposed so that their respective tubes and fins are generally co-planar with each other and are connected to the end tank. In preferred embodiments, the heat exchanger may include a radiator element.
