【Abstract】 The overall design of induction logging tool based on LabVIEW is introduced,it illustrates that the principle of demodulation about the phase-sensitive detector which is one part of the induction logging tool and the method to achieve phase-sensitive demodulation with LabVIEW.The experiment about six-coil system’s vertical property in a homogeneous low-resistivity formation and the experimental curves show that the induction logging tool based on LabVIEW works well and the phase-sensitive detector meet the requirements of the experiment.更多还原
