Application of Space-time Multi-shot Continuous Directional Coring Tech.
Abstract:To solve the problems of non-vibration-resistance and low recovery of rock samples existing in orientation instrument which takes radial as reference, KD Orientation Instrument was developed out based on the relationship between time and space position of borehole. The basic structure, technical data and application in situ of the instrument were introduced in details.
