Integrated logging tool for borehole |
摘要 |
An apparatus for measuring characteristics of earth formations surrounding a borehole, comprises a resistivity measurement device having a multiplicity of antennae spaced between each other in a longitudinal direction of the apparatus. A neutron measurement device of the apparatus comprises at least a neutron source and at least a neutron detector, each of the neutron detectors being at a distance from the neutron source in the longitudinal direction of the apparatus. The multiplicity of antennae are interleaved with the neutron measurement device in order to reduce a total length of the apparatus and in order to allow a determined area of the earth formation to be measured simultaneously using the neutron measurement device and the resistivity measurement device.
