摘要
FIELD: oil and gas industry.;SUBSTANCE: continuous measurement is carried out on profiles above intended field or in water layer of perspective area. The concentration of heavy metals is measured by means of ion-selective electrodes selectively reacting to ions of heavy metals of copper (Cu), lead (Pb), cadmium (Cd), silver (Ag) and mercury (Hg). The anomalies in concentrations of heavy metals are defined by the excessive amplitude of concentration above the background. If no silver (Ag) and mercury (Hg) anomalies are detected, then by the form and arrangement of Cu, Pb and Cd anomalies, the field is drilled out to make corrections in Cu, Pb and Cd concentration excluding Ag and/or Hg effect on experimental dependencies. The anomalies in corrected Cu, Pb And Cd values are defined. The field is drilled out in the form and arrangement of the anomalies. Additionally, helium concentration is continuously measured by means of optomechanical chip consisting of nano-waveguide and cantilever attached thereto. Helium anomalies are recorded by means of helium detector and module of standard holographic matrices with recorded spectra of NMR substance atoms in aqueous medium.;EFFECT: expanded functional capabilities, increased reliability of searches, reduced labour input.;1 cl
