Hardware-Methodical Complex of Borehole Seismic Exploration AMC-VSP-3-48

The equipment AMC-VSP-3-48 is designed for highly sensitive three-component borehole seismic exploration in vertical and directional wells.

The composition of the equipment:

• Digital seismic multi-module downhole probe, consisting of identical downhole receiver modules interconnected by cable jumpers, a relay module and a GK module (for linking depths).
• A set of ground equipment, which includes a NOTEBOOK-type computer, a software-controlled power supply unit for the borehole probe and an interface unit containing digital telemetric communication units with a borehole probe, interfacing with a system for synchronizing seismic excitations and recording ground-based control signals.
• Technological software (TPO), which provides automatic testing of the entire complex, management of all technological processes during the execution of work, conducting preprocessing and quality control of the received data, automation of maintaining and documenting the operator’s report.

Features and Benefits

• the possibility of increasing the number of receiving modules in the probe, their interchangeability;
• the ability to work with any type of wireline cable, including single core;
• ultra-low level of intrinsic instrumental noise, which allows recording weak seismic signals and using seismic non-explosive sources with low energy during operation; lack of industrial network interference;
• the presence in the receiving modules of program-controlled calibrators that allow you to control and take into account changes in the metrological characteristics of electronic measuring channels and geophones in real borehole conditions;
• the small size and mass of the receiving modules, as well as the use in the modules of a program-controlled powerful electromechanical clamping device that provides the minimum effect of the resonance of the "device-well wall" system, as well as interference waves (hydraulic, cable waves) on recorded seismic vibrations;
• the possibility of additional depth control using the built-in gamma-ray logging module;
• ease of use and versatility of TPO, providing the possibility of its use in various modifications of borehole seismic exploration
