ON THE CORRECTNESS OF THE THICKNESS FORECAST AND POROSITY OF RESERVOIRS, IDENTIFIED ACCORDING TO SEISMIC SURVEYING MATERIALS

Abstract

The urgency of the work lies in the fact that in performing seismic works in midrange 0÷120 Hz resolution of the research falls significantly. The possibility of identification and correlation of 2÷10 m net
reservoirs, their porosity and fluid type determination is excluded.
To eliminate these drawbacks, it is proposed to:
1) use single sources of vibrations and pickups instead of patterns;
2) increase the sweep signal taper for lessening surface-wave mode;
3) choose the optimal bin value, that provides the
preservation of the frequency interval of summing
signals and positive traceability of reflecting interfaces throughout the site of interest;
4) work out a program, layers thickness that provides determination according to the values of seismic signal amplitudes.
It is shown, that the assigned tasks for processing
and seismic signals interpretation can be resolved
when implementing high-resolution VPS-Geo seismology survey.
