Новые технологии геофизических исследований для наклонно направленного бурения
Разработана методика и технические средства для проведения электромагнитных зондирований методом ЗСБ-МПП с поверхности воды при изысканиях под ННБ и микротоннели. Зондирования проводятся в режиме непрерывного сканирования разреза по системе площадной съемки
в движении со скоростью до 2–3 км/ч. Глубина исследований составляет до 50 м при слое воды до 20 м. Метод применялся на переходах через реки Амур, Уссури, Ока, Ангара, Кубань и другие.
New Technologies of Geophysical Studies for Directional Drilling
Yu.Yu. Dmitriev (CJSC “SRIDS “GeoEngineering”, Krasnodar)
#2, p 8
A technology together with the hardware have been developed to conduct electromagnetic sounding using the nearfield transient EM sounding and transient surveying from the water surface. The data acquired is used in further survey for directional drilling and microtonnels. Sounding is conducted in the mode of the depth section continuous scanning using three-dimensional survey at a speed of 2 to 3 km/h. The surveying depth is down to 50 m with the water layer depth down to 20 m. This technique was used for crossing the Rivers of Amur, Ussuri, Oka, Angara, Kuban and others.
