is designed for oil/gas, coal, ore and hydrogeological wells investigation with a diameter of 150 mm, max. operating pressure up to 25 MPa and max. operating temperature 70 °C.

 

 

Description

Advantages:

  • combination of different geophysical methods according to the solving geological problem and customer demands;
  • informational, energetical, constructive module compatibility;
  • openness for system combination and addition of new transducers on a customer’s demand.

Complex Composition

Digital transducers with a diameter of 48 mm, which realize the following methods:

  • gamma-ray (GR) or spectrometric gamma-ray logging (SGR);
  • density gamma-gamma ray (Density GR);
  • selective gamma-gamma ray (Selective GR);
  • litho-density gamma-gamma ray (Litho-density GGR) lateral logging (LL) or scanning laterolog (Scan LL);
  • neutron-gamma ray (N-GR) or spectral gamma-ray (SGR);
  • neutron-neutron log (GL);
  • full wave acoustical logging (FWAL);
  • magnetizability log;
  • caliper log (CL);
  • temperature and resistivity log (TR).

The equipment AKIPS is compatible with any type of programmable stations.

AKIPS complex can be delivered in two modifications:

telemetry connecting link module, combined with GR module, to which any of the mentioned above modules can be attached from the underside; GR module serves for depth positioning during different round trip operations.

set of separate downhole tools, which constructively cannot be attached.

Delivery completeness: downhole digital modules, facilities for tool calibration, devices for tool servicing, spare tools and accessories kit, certificates, operating manuals.

*Interface unit, IBM-compatible computer Notebook, soft-ware controlled power-supply source, technological software.
