Fractural reservoir has great exploration potential, that has complex anisotropy and is difficult to explore and develop. UltraDo has formed and summarized integrity study technology combining core description, well logging recognizing, seismic prediction and ground stress research based on many years project experience. Especially, pre-stack anisotropy ant body fracture prediction technology takes a important role in prediction for sweet spot types and fracture distribution by studying on the relationship between fracture characteristics of tight reservoir and seismic attenuation character.
