Применение методов сейсмо - и электротомографии для обнаружения зон повышенной трещиноватости при строительстве трубопроводов способом наклонно-направленного бурения в горно-складчатой области

On the site of horizontal directional drilling in the area of Sochi (Krasnodar region) were carried out drilling, geophysical and laboratory works. Under geophysical studies particular attention is paid to the study of of the geological structure of the bedrock, identifying faults and zones of jointing. Our experience has shown, positioning of small-scale heterogeneities of the geological environment such as zones of jointing of the traditional methods of seismic and electrical exploration is characterized by low accuracy. At the same time, the joint application of seismic tomography and electro tomography demonstrates greater efficiency and reliability of detection of these zones.
