Abstract

The self-reactance method for locating hidden subsurface non-metal pipelines made of high molecular compounds (polyethylene, polystyrene, PVC, polypropylene) is proposed. It is based on the self-reactance properties of liquids in pipelines, which appear with the forced polarization of liquid by turning the magnetic axis of the protons at some angle in relation to the magnetic field of Earth. After the polarization pulse a liquid proton axis precession starts in the direction to the magnetic field of Earth. It results in appearance of the variable mag­netic field of free nuclear precession with Larmor frequency, that testifies to the location of subsurface pipeline with a liquid. Proton precession time depends on the liquid and serves as a sign for recognition of liquid type in a pipeline.
