METHOD FOR BLAST EXCITATION OF SEISMIC VIBRATIONS IN A WELL

摘要

A method for blast excitation of seismic vibrations in a well includes displacement and installation at given depth in the well of an exciter of seismic vibrations with n explosive charges and electric detonators by means of electric logging cable or tube systems, and implementation of excitation of seismic vibrations through detonation of charges of exciter of seismic vibrations. Excitation of seismic vibrations is carried out at one level in the well through transportation in turn to the place of excitation of seismic vibrations of single charges from group of charges that are held at given safe distance from the place of excitation of seismic vibrations. One performs alternative separation of charges from the group for transportation to the place of excitation of seismic vibrations and sequential realization of separate explosions of charges.
