摘要： A directional tool and method of surveying a wellbore with the directional tool in a borehole string. A first sensor of the directional tool is disposed in a non-homogeneous ambient magnetic field. A first applied magnetic field is applied to the first sensor. A first measurement is obtained at the first sensor while the first sensor is disposed within the non-homogeneous ambient magnetic field and with the first applied magnetic field applied. A second applied magnetic field is applied to the first sensor. A second measurement is obtained at the first sensor while the first sensor is disposed within the non-homogeneous ambient magnetic field and with the second applied magnetic field applied. The directional tool is calibrated based on the first and second measurement. A downhole survey measurement is obtained with the calibrated directional tool in the wellbore.

摘要： A method, system and drilling apparatus for directional drilling are disclosed. A drill bit is located at a downhole end of a drill string in a borehole. A length of the borehole between a surface location and the drill bit at the downhole end of a drill string is determined and an azimuth angle and inclination of the drill bit is obtained. The length of the borehole may be determined by recording an arrival time at a downhole location of an acoustic pulse travelling from a surface location to the downhole location and determines the travel time and borehole length therefrom. A downhole processor determines a position and orientation of the drill bit from the determined length, azimuth angle and inclination and alters a steering parameter of the drill bit using the determined position and orientation of the drill bit to obtain a selected trajectory for drilling the borehole.

摘要： An apparatus and method to detect a fluid flow. The apparatus includes a nuclear magnetic resonance (NMR) tool to perform an NMR measurement on the fluid in a sensitive volume by establishing a magnetic field in the sensitive volume that exhibits a change in magnitude in a direction of the fluid flow when the fluid flow is radial with respect to the NMR tool and by transmitting refocus pulses, without any tipping pulse, to obtain the NMR measurement comprising spin echo signals. The system also includes a processor to receive the NMR measurement from the NMR tool and determine whether the fluid flow exists based on an amplitude of the NMR measurement.
